Technical Field
[0001] The present disclosure relates to the field of razors. More specifically, the present
disclosure relates to razor connectors which attach a razor cartridge to a razor handle.
Background
[0002] Razors are well known everyday items to shave of unwanted bodily hair, e.g. beard
hairs. The razor may comprise a razor cartridge including blades configured to cut
the hair and a razor handle used attached thereto. In use, a user holds the razor
handle and brings the razor cartridge into contact with a portion of skin. By movement
of the razor handle the razor cartridge moves in a shaving direction and unwanted
hair is removed. The razor cartridge may be releasably connected to the razor handle
via a razor connector. A releasable attachment of the razor cartridge may allow exchanging
the razor cartridge, for example when the blades have become dull, instead of discarding
the entire razor. However, razor connectors typically comprise complex mechanisms
requiring multiple components, for example springs, pushers, push buttons, releasing
mechanisms etc. The complex mechanisms increase the assembly complexity and increase
the production time. Further, the multiple components, especially those that are movable,
increase the risk of system failure as they are more prone to breaking.
[0003] The present disclosure aims to address the aforementioned issues in optimizing razor
connectors.

Detailed Description
[0074] Hereinafter, a detailed description will be given of the present disclosure. The
terms or words used in the description and the aspects of the present disclosure are
not to be construed limitedly as only having common-language or dictionary meanings
and should, unless specifically defined otherwise in the following description, be
interpreted as having their ordinary technical meaning as established in the relevant
technical field. The detailed description will refer to specific embodiments to better
illustrate the present disclosure, however, it should be understood that the presented
disclosure is not limited to these specific embodiments.
[0075] Razor connectors typically comprise multiple components, in particular multiple movable
components. The number of components increases the required assembly time during production,
as well as the risk of breaking of the razor connector.
[0076] In a first aspect, the present disclosure relates to a razor connector 10 configured
to connect a razor cartridge 100 to a razor handle 12. The razor connector 10 comprises
at least one interlocking feature configured to interlock with at least one interlocking
part of the razor cartridge 100 and a push-button 16 integrally formed with a hinge
24. The push-button 16 is configured to rotate the hinge 24 from a first to a second
position upon actuation, wherein rotation of the hinge 24 from the first to the second
position is configured to disconnect the razor cartridge 100 from the razor connector
10.
[0077] The razor connector 10 according to the first aspect may significantly reduce the
required assembly time compared to other types of razor connectors.
[0078] Figure 1 illustrates a top view of an exemplary razor connector 10 according to the
present disclosure with a razor handle 12. The razor connector 10 may be connected
to the razor handle 12 at a proximal end and a razor cartridge 100 at the distal end,
as shown in Figure 3 and 4. In embodiments, the razor connector 10 may comprise a
tongue, configured to allow pivotable movement of the razor cartridge 100 relative
to the razor handle 12. The tongue 14 may extend from a distal end of the razor connector
10. The distal end and proximal end may define the proximal-distal razor connector
axis 40. Figure 1 shows the proximal-distal razor connector axis 40 running centrically
through the razor connector 10.
[0079] Figure 2 is a more detailed top view of the exemplary razor connector 10. Figure
2 shows two hinges 24a, 24b. In embodiments, the razor connector may comprise only
one hinge.
[0080] As shown in Figure 2 the hinge 24b is integrally formed with the push-button 16.
The hinge 24 may be arranged towards the razor connector's 10 distal end. The hinge
24 may be arranged in distal direction of the push-button 16 and/or may be attached
to the push-button 16 at the hinge's 24 proximal end. As is furthermore depicted in
Figure 2, the push-button 16 may be connected to the hinge 24b by a strut 30.
[0081] In embodiments, the hinge 24 may comprise a first 24a and a second hinge 24b, wherein
the first 24a and the second hinge 24b may be disposed opposing one another, in particular
wherein the proximal-distal razor connector axis 40 is disposed between the first
24a and the second hinge 24b. Figure 4 depicts an embodiment wherein the first hinge
24a is connected to a first push-button 16a, in particular by a first strut 30a, and
the second hinge 24b is connected to a second push-button 16b, in particular by a
second strut 30b.Alternatively, the first hinge 24a may be connected to the push-button
16 by a first strut 30a and the second hinge 24b may be connected to the push-button
16 by a second strut 30b. A single push-button 16 may facilitate handling by the user.
Two push-buttons 16a, 16b may require less force for actuation of the push-buttons
16a, 16b.
[0082] Alternatively or additionally, the razor the push-button 16 may not be directly connected
to a hinge 24. As depicted in Figure 8, the push-button 16 may comprise a push-protrusion
44a. The push-protrusion 44a may push against the proximal end of the hinge 24a, in
particular a portion of the proximal end of the hinge 24a disposed towards the razor
connector axis 40, when the push-button 16 is actuated, which may lead to the rotation
of the hinge 24a. The strut 30 and push-protrusion 44a may be suitably combined.
[0083] In embodiments, the push-button 16 may move from a proximal position to a distal
position upon actuation. As the push-button 16 is integrally formed with the hinge
24, the push-button 16 may transfer forces to the hinge 24. Hence, when the push-button
16 is moved from a proximal position to distal position, the push-button 16 may exert
a force in distal direction upon the hinge 24.
[0084] In embodiments, the hinge 24 may be configured to rotate from the first position
to the second position about an axis of rotation 42. The hinge's axis of rotation
42 may be substantially perpendicular or perpendicular to the proximal-distal razor
connector axis 40. The hinge's axis of rotation 42 may be disposed further away from
the proximal-distal razor connector axis 40 compared to the push-button 16 and/or
the strut 30, as is indicated for example in Figure 2. Hence, when the push-button
16 is moved in distal direction, a part of the hinge 24 may move at least partly in
distal direction, in particular a part of the hinge 24 disposed closer to the proximal-distal
razor connector axis 40 than the hinge's axis of rotation 42.
[0085] The hinge 24 may perform a hinge-type movement relative to the razor connector 10,
in particular a hinge-type movement about the axis of rotation 42. The term "hinge-type
movement" within this disclosure is well-known in the art and attributed its common
meaning in this technical field. Additionally to the aforementioned definitions, the
term "hinge-type movement" may refer to the hinge 24 performing a rotational movement
relative to the razor connector around the axis of rotation 42.
[0086] As mentioned above, the razor connector 10 according to the first aspect comprises
at least one interlocking feature. As depicted in Figure 6, the at least one interlocking
feature may be a recess 18, in particular a recess 18 configured to interlock with
at least one interlocking protrusion of the razor cartridge 100. Alternatively or
additionally, the at least one interlocking feature may be an interlocking protrusion,
in particular an interlocking protrusion configured to interlock with at least one
recess of the razor cartridge 100
[0087] The interlocking protrusion and the recess may interlock through a snap-fit when
the razor connector 10 is connected to a razor cartridge 100 on its distal end. The
razor connector 10 or parts thereof and/or the razor connector or parts thereof may
be flexible, improving the snap fit and allowing release of the snap-fit.
[0088] The hinge 24 may be configured to disconnect the razor cartridge 100 from the razor
connector 10 upon actuation of the push-button 16 by pushing the at least one interlocking
part of the razor cartridge 100 out of the at least one interlocking feature. More
specifically, the hinge 24 may be configured to disconnect the razor cartridge 100
from the razor connector 10 upon actuation of the push-button 16 by pushing the at
least one interlocking part of the razor cartridge 100 out of the at least one interlocking
feature by at least a part of the hinge 24 moving in the distal direction due to the
rotation of the hinge 24 around its axis of rotation 42.
[0089] As depicted in Figure 3, the hinge 24 may be configured to be in contact with the
razor cartridge 100, when the razor cartridge 100 is connected to the razor connector
10. The hinge 24 may be configured to push the at least one interlocking part out
of the at least one interlocking feature by moving the at least one interlocking part
of the razor cartridge 100 in distal direction relative to the at least one interlocking
feature.
[0090] As depicted for example in Figure 2 and Figure 6, the hinge 24 may comprise a protrusion
20, in particular wherein the protrusion 20 is arranged on a distal end of the hinge
24, in particular wherein the protrusion 20 is configured to be in contact with the
razor cartridge 100, when the razor cartridge 100 is connected to the razor connector
10. The protrusion 20 may improve the disconnection mechanism of the razor connector
10, in particular by exerting a force in distal direction on an adjacent part of the
razor cartridge 100 when the hinge 24 is rotated about its axis of rotation 42. The
protrusion 20 may act as a cam, hence the protrusion 20 may transform rotary motion
to linear motion, in particular the protrusion 20 may transform hinge's 24 rotational
movement about its axis of rotation 42 into a motion in the distal direction. In embodiments,
the first hinge 24a may comprise a first protrusion 20a and the second hinge 24b may
comprise a second protrusion 20b.
[0091] In embodiments, the protrusion 20 may be configured to disconnect the razor cartridge
100 from the razor connector 10 upon actuation of the push-button 16 by pushing the
at least one interlocking part of the razor cartridge 100 out of the at least one
interlocking feature, more specifically wherein the protrusion 20 may be configured
to disconnect the razor cartridge 100 from the razor connector 10 upon actuation of
the push-button 16 by pushing the razor cartridge's 100 protrusion of out of the razor
connector's 10 recess 18 and in particular wherein the protrusion 20 may be configured
to disconnect the razor cartridge 100 from the razor connector 10 upon actuation of
the push-button 16 by pushing the razor cartridge's 100 interlocking protrusion of
out of the razor connector's 10 recess 18 by moving in the distal direction due to
the rotation of the hinge 24 around its axis of rotation 42.
[0092] Movement of the at least one interlocking part of the razor cartridge 100 in distal
direction may release the snap fit. More specifically, as the hinge 24 and/or protrusion
20 may be in contact with the razor cartridge 100, movement of the at least part of
the hinge 24 in distal direction may also move an adjacent part of the razor cartridge
100, e.g. a part of the razor cartridge comprising the at least one interlocking part,
in distal direction leading to release of the snap fit.
[0093] Alternatively, in embodiments, the hinge 24 and/or protrusion 20 may be configured
to push the at least one interlocking part out of the at least one interlocking feature
by moving the at least one interlocking part of the razor cartridge 100 in the distal
direction and away from the proximal-distal razor connector axis 40 relative to the
at least one interlocking feature. Movement of the at least one interlocking part
of the razor cartridge 100 away from the proximal-distal razor connector axis 40 may
undo the snap-fit and the movement into the distal direction may prevent reengagement
as the at least one interlocking feature and at least one interlocking part may not
be aligned anymore. Movement of the interlocking part of the razor cartridge 100 away
from the proximal-distal razor connector axis 40 may for example be achieved by at
least part of the hinge 24 or the protrusion 20 being configured to move between part
of the razor cartridge 100 and the razor connector 10, e.g. parts of the razor cartridge
100 and the razor connector 10 in proximity of the at least one interlocking feature
and at least one interlocking part. As shown in Figure 5 the connector sleeve 102
may comprise an angular portion, which may facilitate movement by the protrusion 20
between the receiving head 28 and the razor connector sleeve 102. Further, in embodiments
the protrusion 20 may comprise an angular portion at its distal end, which may facilitate
movement by the protrusion 20 between the receiving head 28 and the razor connector
sleeve 102.
[0094] Pushing the at least one interlocking part of the razor cartridge 100 out of the
at least one interlocking feature of the razor connector 10 shall not be construed
as requiring the hinge 24 or protrusion 20 to directly contact the at least one interlocking
feature or part. The hinge 24 or protrusion 20 may merely push against another part
of the razor cartridge 100, whereby the razor cartridge 100 moves in distal direction,
which in turn may lead to the push out.
[0095] In embodiments, the push-button 16 may be connected to an elastic structure 22 configured
to exert a biasing force on the push-button 16 to return the push-button from the
distal position to the proximal position, in particular wherein the push-button and
the elastic structure 22 are integrally formed.
[0096] In embodiments, a cross-section of the elastic structure 22, in particular along
the proximal-distal razor connector axis 40, may be V-shaped, or curved, in particular
at least partially a semi-circle. The shape of the elastic structure 22, which is
partially defined by its cross-section, may be chosen based on the desired movement
of the push-button 16 upon actuation, as well as the desired movement of the hinge
24 upon actuation. For example, if the hinge 24 or protrusion 20 are configured to
push the at least one interlocking part out of the at least one interlocking feature
by moving the at least one interlocking part of the razor cartridge 100 in the distal
direction and away from the proximal-distal razor connector axis 40 relative to the
at least one interlocking feature, the shape of the elastic structure 22 may be chosen
such that at least a part of hinge 24 or protrusion 20 move between part of the razor
cartridge 100 and the razor connector 10 upon actuation of the push-button 16. For
example, a curved elastic structure 22 may allow the push-button 16 to move towards
the proximal-distal razor connector axis 40 which may move part of the hinge 24 or
protrusion 20 also towards the proximal-distal razor connector axis 40, such that
the part of the hinge 24 or protrusion 20 move between part of the razor cartridge
100 and the razor connector 10.
[0097] Figure 7 is a breakout view of the razor connector 10 showing an embodiment of the
elastic structure 22 in a top view. A plurality of details, such as the hinge 24,
have been omitted in Figure 7. As depicted in Figure 7, the elastic structure 22 may
comprise one or more circular arcs, in particular wherein a top-view of the elastic
structure 22 is shaped as one or more circular arcs. The circular arcs may provide
a high degree of elastic force to the elastic structure 22, even when integrally formed
with the push-button 16.
[0098] In embodiments, the push-button 16 may be preloaded when the razor cartridge 100
is connected to the razor connector 10; and/or, wherein the hinge 24 may be preloaded
when the razor cartridge 100 is connected to the razor connector 10. In embodiments,
the push-button 16 may be moved towards the proximal direction of the proximal-distal
razor connector axis 40 when preloaded. Preloading the push-button 16 or hinge 24
when connecting the razor cartridge 100 may reduce the required force for actuating
the push-button to disconnect the razor cartridge, as at least part of the force is
already provided due to the preloading.
[0099] In embodiments, the protrusion 20 or hinge 24 may be configured to preload the razor
cartridge 100 when the razor cartridge 100 is connected to the razor connector 10.
Preloading the razor cartridge 100 may bias the razor cartridge 100 towards an angle
relative to the razor handle 12, which may improve the handling of the razor for the
user.
[0100] As mentioned above, the razor connector 10 may comprise a tongue 14, configured to
allow pivotable movement of the razor cartridge 100 relative to the razor handle 12.
The tongue 14 may connect and/or slide into a corresponding feature of the razor cartridge
100. The tongue 14 may restrict movement of the razor cartridge 100 relative to the
razor connector 10 in certain axis. The tongue 14 may restrict movement of the razor
cartridge 100 relative to the razor connector 10 orthogonally to the proximal-distal
razor connector axis 40 and/or pivotable movement around the proximal-distal razor
connector axis 40. This may improve the connection between the razor connector 10
and the razor cartridge 100, in particular it may prevent accidental release of the
razor cartridge 100. The tongue 14 may however allow pivotable movement around an
axis disposed orthogonally to the proximal-distal razor connector axis 40. This may
in use allow the razor cartridge 100 to align to the surface of a user's skin. The
tongue 14 may allow the razor cartridge 100 to align to the user's skin by a pivotable
movement but may also apply a restoring force on the razor cartridge 100 to return
to its original orientation relative to the razor handle.
[0101] In embodiments, the tongue 14 may be a flexible tongue 14. The term "flexible tongue"
within this disclosure may refer to an elongated structure, in particular a structure
elongated at least partly along the proximal-distal razor connector axis 40, wherein
the elongated structure comprises or consists of an elastic material. The term "flexible
tongue" may refer to an elongated structure allowing pivotable movement of a connected
part, in particular a razor cartridge" due to elastic deformation. Additionally or
alternatively, the term "flexible tongue" may refer to a flexible elongated structure
not comprising movable parts, such as springs or slidable parts.
[0102] The flexible tongue 14 may further reduce the assembly time of the razor connector
10 compared to other components allowing pivotable movement of the razor cartridge
100. Further, the flexible tongue 14 may be integrally formed with other parts of
the razor connector 10. The term "elastic material" within this disclosure may refer
to a material which undergoes deformation when exposed to a force and returns, at
least partly, to its original size and shape after the force is removed. Additionally
or alternatively, the term "elastic material" within this disclosure may refer to
a material which has an elongation at yield of at least 1 %, more specifically at
least 1.5 % and in particular at least 2 %, measured according to ISO 527-1:2019.
[0103] In embodiments, the razor connector 10 may comprise a receiving head 28 configured
to receive a connector sleeve 102 of the razor cartridge 100. The receiving head 28
may align the tongue during its insertion into the razor cartridge 100. Further, the
receiving head 28 may aid in preventing movement of the razor cartridge 100 orthogonally
to the proximal-distal axis razor connector proximal-distal razor connector axis 40.
The razor connector 10 may also connect to the razor connector 100 in other ways,
in particular through other types of plug and socket connection types. Additionally,
movement of the at least one interlocking part of the razor cartridge 100 away from
the proximal-distal razor connector axis 40 may for example be achieved by at least
part of the hinge 24 or the protrusion 20 being configured to move between the receiving
head 28 and the connector sleeve 102 upon actuation of the push-button 16.
[0104] In embodiments, the push-button 16 may be arranged in proximal direction of the receiving
head's 28 distal end. Arranging the push-button 16 proximally of the receiving head's
28 distal end may prevent unintentional interaction of the push-button 16 with the
razor cartridge 100 and provide improved handling for the user.
[0105] In embodiments, the push-button 16 may comprise at least one actuation surface 26
configured to be actuated by a user to release the razor cartridge 100, in particular
by moving the actuation surface 26 in distal direction of the proximal-distal razor
connector axis 40.
[0106] In embodiments, the at least one actuation surface 26 may be disposed substantially
perpendicular or perpendicular to the proximal-distal razor connector axis 40. Arranging
the at least one actuation surface 26 substantially perpendicular or perpendicular
to the proximal-distal razor connector axis 40 may allow ergonomic actuation by the
user, in particular with his thumb.
[0107] In embodiments, the elastic structure 22 may be arranged between the actuation surface
26 and the hinge 24 and/or the protrusion 20.
[0108] In embodiments, the at least one actuation surface 26 may comprise an indicator,
more specifically a haptic indicator and in particular a protrusion, a dot, a cavity,
a groove and/or a rubber element. The haptic indicator may facilitate the identification
of the actuation surface 26 by the user, in particular without looking at the razor
connector 10 and only through haptic perception.
[0109] In embodiments, the razor connector 10 may have a top side 32 and bottom side 36
(shown for example in Figure 2 and Figure 6). The top side 32 may be the side facing
against a shaving direction and the bottom side 36 the side facing towards the shaving
direction. Alternatively or additionally, the top 32 and bottom 36 side may be defined
relative to other components. Alternatively or additionally, the bottom side may be
the razor connector's 10 side comprising the tongue, in particular the flexible tongue
14. Alternatively or additionally, the bottom side may be the razor connector's 10
side comprising the at least one interlocking feature. Additionally, the top side
32 may be the side opposite of the bottom side 36.
[0110] As depicted in Figures 5 and Figure 6, in embodiments, the tongue 14 may comprise
a first section extending parallel to the proximal-distal razor connector axis 40
along the bottom side 36 of the razor connector 10 and a second section diverging
towards the top side 32 of the razor connector 10. This configuration may, in instances,
be selected to allow the razor cartridge 100 to pivot relative to an axis disposed
orthogonally to the proximal-distal razor connector axis 40, while preventing movement
orthogonally to the proximal-distal razor connector axis 40.
[0111] In embodiments, the receiving head 28 may comprise a top side 34 (shown for example
in Figure 2) and a bottom side 38 (shown in Figure 6). The top 34 and bottom side
38 of the receiving head 28 may be defined accordingly to the top 32 and bottom side
36 of the razor connector 10. As shown in Figure 6 the flexible tongue 14 may be connected
to the receiving head 28, more specifically to the receiving head's 28 proximal end
and in particular the receiving head's 28 bottom side's 38 proximal end. This configuration
may increase the length of the tongue, which may allow for a greater deflection at
the same force compared to a shorter tongue, which may improve the alignment of the
razor cartridge 100 to the user's skin during the shaving action.
[0112] In embodiments, the push-button 16 may be arranged on the top side 32 or bottom side
36 of the razor connector 10, in particular on the top side 32 of the razor connector
10.
[0113] In embodiments, the tongue 14 may have a polygonal cross-section, more specifically
a square, rectangular or octagonal shape and in particular a rectangular shape. In
embodiments, a corner of the polygonal cross-section may be round. The rounded edges
may facilitate sliding the tongue into the razor cartridge's 100 corresponding feature.
[0114] In embodiments, the protrusion 20 may be placed at the top side 32 of the razor connector
10, in particular on the hinge's 24 distal section at the top side 32. In embodiments,
the protrusion 20 may be placed at the bottom side 36 of the razor connector 10, in
particular on the hinge's distal section at the bottom side 36. As shown for example
in Figure 2 and Figure 6, the hinge 24 may comprise the protrusion 20 on its distal
section at both the top side 32 and bottom side 36. This configuration may improve
the release of the razor cartridge 100. A protrusion 20 placed only at the top side
32 or bottom side 36 may only tilt the razor cartridge 100 when the push-button 16
is actuated. A protrusion at both the top side during the actuation of the push-button
16 may push the razor cartridge 100 straight towards the razor connector's 10 distal
end, which may release the razor cartridge 100. However, it may also be sufficient
to place the protrusion 20 at only either the top side 32 or the bottom side 36. In
particular, if the protrusion 20 is placed on the side comprising the at least one
interlocking feature, in particular the recess 18, the protrusion 20 may push the
razor cartridge 100 so far towards the distal end on that side, that the razor cartridge
100 is released from the razor connector 10, although the overall razor cartridge
100 only tilts relative to the razor connector 10.
[0115] In embodiments, the at least one interlocking feature may be positioned proximally
of the receiving head's 28 distal end, more specifically on the bottom side 36 of
the razor connector 10 on the receiving head 28 proximally of the receiving head's
28 distal end and in particular on the bottom side 36 of the razor connector 10 on
the receiving head 28 proximally of the receiving head's 28 distal end adjacent to
the tongue. Placing the at least one interlocking feature, in particular a recess
18 on the bottom side 38 of the razor connector 10 may be used e.g. if the bottom
side 38 of the razor connector 10 is facing against the shaving direction, in some
instances, as during the shaving action the at least one interlocking feature may
be pressed together, due to the forces transferred to the razor cartridge 100 during
the shaving action.
[0116] In embodiments, different parts of the razor connector 10 may be integrally formed
with other parts of the razor connector 10. This may decrease the assembly time of
the razor connector 10.
[0117] In embodiments, the push-button 16 may be integrally formed with the at least one
interlocking feature. Additionally or alternatively, the push-button 16 may be integrally
formed with the tongue. In embodiments, the push-button 16, the at least one interlocking
feature and the tongue 14 may be integrally formed.
[0118] In embodiments, the razor connector 10 may be a one-piece part. Integrally forming
parts of the razor connector 10 may decrease the assembly time of the razor connector
10 drastically. In particular, manufacturing the razor connector 10 as a one-piece
part may lead to no assembly time for the razor connector 10 at all. Figures 1 to
7 show the razor connector 10 as a one-piece part.
[0119] To manufacture the razor connector 10 as a one-piece part different manufacturing
technologies may be used. The razor connector 10 may be, in some instances, manufacturable
by additive manufacturing technologies. The razor connector 10 may have a complex
geometry, which may be efficiently manufacturable by additive manufacturing. In particular,
the razor connector 10 may comprise multiple undercuts, which may make for example
injection molding inefficient, especially if the razor connector 10 is intended to
be manufactured as a one-piece part.
[0120] The razor connector 10 may be an individual part and connected to the razor handle
12 by a detachable or non-detachable connection, for example a push-in connection.
Manufacturing the razor connector 10 as an individual part may be advantageous if
the razor handle 12 can be rapidly and efficiently manufactured, e.g. by injection
molding, whereas the razor connector 10 can only be manufactured with more cost and
time intensive processes, e.g. additive manufacturing. In that case, an individually
manufactured razor handle 12 and razor connector 10 may reduce the manufacturing time
and cost of the complete razor. Further, a releasably attached individually formed
razor connector 10 could be exchanged if it is worn out, while retaining the razor
handle 12.
[0121] Alternatively, the razor connector 10 may be integrally formed with the razor handle
12. Integrally forming the razor connector 10 with razor handle 12 reduces the assembly
time further.
[0122] In embodiments, the razor connector 10 may comprise a plurality of layers, in particular
a plurality of layers substantially parallel to each other. The layered structure
may comprise a plurality of layers, in particular a plurality of layers substantially
parallel to each other. Additive manufacturing technologies, such as fused filament
fabrication or material jetting may lead to a plurality of layers, in particular a
plurality of layers substantially parallel to each other.
[0123] In embodiments, a layer of the plurality of layers may have a thickness between about
5 µm to about 100 µm, more specifically between about 10 µm to about 50 µm and in
particular between about 15 µm to about 30 µm.
[0124] In embodiments, a layer of the plurality of layers may have a thickness between about
0.05 mm to about 0.6 mm, more specifically between about 0.1 µm to about 0.4 mm and
in particular between about 0.15 mm to about 0.3 mm.
[0125] The thickness of the plurality of layers may depend upon the process used for manufacturing.
Further, a smaller layer thickness may lead to an increased manufacturing time of
the razor connector 10, but may also increase the mechanical stability and dimensional
accuracy of the razor connector 10.
[0126] In embodiments, the razor connector 10 may comprise a first polymer, more specifically
a photopolymer and in particular an ABS-like polymer and/or polypropylene-like polymer.
A photopolymer and in particular an ABS-like polymer and/or polypropylene-like polymer
may be processable by an additive manufacturing process such as stereolithography.
The first polymer may have a Shore D hardness between about 50 to about 120, more
specifically between about 55 to about 100 and in particular between about 60 to about
90, measured according to ISO 868:2003. The first polymer may be for example Durus
or Rigur, by the company Stratasys, Ltd.
[0127] In embodiments, the razor connector 10 may comprise a second polymer. The second
polymer may have a shore A hardness between about 10 to about 95, more specifically
between about 25 to about 80 and in particular between about 35 to about 60, measured
according to ASTM D2400 - 15. The second polymer may be for example Tango or Agilus
30, by the company Stratasys, Ltd.
[0128] In embodiments, the razor connector 10 may comprise a third polymer, more specifically
a thermoplastic polymer and in particular ABS and/or polypropylene.
[0129] In embodiments, the razor connector 10 may comprise a fourth polymer, more specifically
a thermoplastic elastomer and in particular a TPA, a TPC, a TPO, a TPS, a TPV, a TPZ
and/or a TPU.
[0130] Thermoplastic elastomers, as well as ABS and/or polypropylene may be processable
by technologies wherein a solid material is liquified and subsequently resolidified
for manufacturing, for example extrusion. Thermoplastic elastomers, as well as ABS
and/or polypropylene may in particular be processable by additive manufacturing technologies
such as fused filament fabrication and/or selective laser melting.
[0131] Additive manufacturing technologies may also be employed as multi-material processes,
wherein a one-piece part comprising at least two different materials can be manufactured.
For example, stereolithography and fused filament fabrication may be used to create
multi-material parts. In fused filament fabrication the manufacturing device, e.g.
the 3D-printer, may comprise multiple nozzles, wherein each nozzle is configured to
extrude a different polymer. In stereolithography the part to be produced may change
between vats comprising different precursors. Hence, additive manufacturing may be
employed to optimize properties of certain parts and/or regions of the razor connector
10 by varying the choice of material locally.
[0132] The second and/or fourth polymer may have a lower modulus of elasticity compared
to the first and/or third polymer. A material with a lower modulus of elasticity exhibits
a higher degree of deformation when exposed to the same force compared to a material
with a higher modulus of elasticity. The second and/or fourth polymer may have a lower
hardness, in particular shore A and/or shore D hardness, compared to the first and/or
third polymer, which may allow for a higher degree of deformation of the second and/or
fourth compared to the first and/or third polymer when exposed to the same force.
[0133] In embodiments, the hinge 24 may be connected to the receiving head 28 at a connection
shoulder, in particular wherein the connection shoulder comprises the second and/or
fourth polymer. The hinge 24 may perform a hinge-type movement relative to the receiving
head 28 in particular a hinge-type movement wherein the connection shoulder acts as
the axis of rotation 42. Additionally to the aforementioned definitions, the term
"hinge-type movement" may refer to the hinge 24 performing a rotational movement relative
to the razor connector and/or receiving head 28 around the connection shoulder. The
hinge may be connected to the receiving head 28 at two connection shoulders, wherein
one connection shoulder is positioned on the top side 32 and/or top side 34 of the
receiving head 28 and wherein one connection shoulder is positioned at the bottom
side 36 and/or bottom side 38 of the receiving head 28. In embodiments, the connection
shoulder may comprise the second and/or fourth polymer. In embodiments, the connection
shoulder may comprise the second and/or fourth polymer and the hinge 24 and/or the
receiving head comprise the first and/or third polymer. Manufacturing the connection
shoulder with a material exhibiting lower modulus of elasticity may reduce the required
force to actuate the hinge 24 and thereby the push-button 16. Alternatively or additionally,
the connection shoulder may comprise a joining-structure, for example a pin-shaped
structure, connecting the hinge 24 to the receiving head 28, in particular wherein
the pin-shaped structure is tapered. The tapering may allow for improved rotation
about the axis of rotation 42.
[0134] In embodiments, the flexible tongue 14 may comprise the second and/or fourth polymer.
The flexible tongue 14 comprising the second and/or fourth polymer, more specifically
a second and/or fourth polymer exhibiting a lower modulus of elasticity compared to
the first and/or third, may in use allow the razor cartridge 100 to align to the skin
of the user under less force. However, a flexible tongue 14 comprising the first and/or
third polymer with a higher modulus of elasticity may provide a higher stability to
the razor cartridge 100. In embodiments, the flexible tongue 14 may comprise the first
and/or third polymer and the second and/or fourth polymer. This may allow adjusting
the flexible tongue's 14 modulus of elasticity to an optimized value. In embodiments,
the elastic structure 22 may comprise the second and/or fourth polymer. The elastic
structure 22 comprising the second and/or fourth polymer may reduce the force required
to actuate the push-button 16 and/or may allow the push-button 16 to move to a greater
extent, before the elastic structure 22 breaks.
[0135] In embodiments, the hinge 24 and/or protrusion 20 may comprise the first and/or third
polymer. The hinge 24 and/or protrusion 20 comprising the first and/or third polymer,
more specifically a first and/or third polymer exhibiting a higher modulus of elasticity
may lead to a higher rigidity of the parts which may improve the actuation mechanism,
in particular the release of the razor cartridge 100 upon actuation. A higher rigidity
of the hinge 24 may lead to a higher proportion of the force applied during actuation
to be transferred to the protrusion 20, in particular as less force is absorbed by
elastic deformation of the hinge 24. Similarly, a higher rigidity of the protrusion
20 may lead to a higher force transfer to the razor cartridge 100, as less force is
absorbed by elastic deformation of the protrusion 20.
[0136] In embodiments, the push-button 16 may comprise the first and/or third polymer.
[0137] In embodiments, the actuation surface may comprise the second and/or fourth polymer.
The second and/or fourth polymer may have a higher tack and/or coefficient of friction
compared to the second and/or fourth polymer and may therefore provide better grip
to the user.
[0138] In embodiments, the tongue 14 may be connected to a spring, more specifically a spring
configured to allow the tongue to move along the proximal-distal razor connector axis
40 and in particular a spring that compresses and stretches along the proximal-distal
razor connector axis 40.
[0139] In a second aspect the present disclosure relates to a razor system comprising a
razor connector 10 according to any preceding embodiment according to the first aspect
and a razor cartridge 100, wherein the razor cartridge 100 is releasably attached
to the razor connector 10.
[0140] In embodiments according to the second aspect the razor system may further comprise
a razor handle 12 connected to the razor connector 10.
[0141] In a third aspect the present disclosure relates to a method for manufacturing a
razor connector 10 any preceding embodiment according to the first aspect according
to the first aspect. The method may comprise manufacturing the razor connector 10
using a computer-controlled manufacturing system, in particular additive manufacturing,
material jetting, fused filament fabrication, stereolithography and/or selective laser
sintering.
[0142] In a fourth aspect the present disclosure relates to a computer-based manufacturing
system for manufacturing a razor connector 10, comprising a control unit adapted to
execute the method according to the third aspect.
[0143] In a fifth aspect the present disclosure relates to a computer program comprising
computer readable code which cause a computer-based manufacturing system to carry
out the method according to the third aspect.
[0144] In a sixth aspect the present disclosure relates to a computer readable medium comprising
the computer readable code according to the fifth aspect.
[0145] In an eighth aspect the present disclosure relates to a model of the razor connector
10 according to any embodiment according to the first aspect for a computer-controlled
manufacturing system, wherein the model is configured to be processed by the computer-controlled
manufacturing system to manufacture the razor connector.
[0146] In a ninth aspect, the present disclosure relates to a computer-readable medium,
wherein the computer-readable medium comprises instructions configured to be processed
by a computer-controlled manufacturing system to manufacture the razor connector 10
according to any embodiment according to the first aspect.
