FIELD OF INVENTION
[0001] The present invention relates generally to a control device.
BACKGROUND OF THE INVENTION
[0002] Multifunctional and direction control devices or actuators like joysticks can be
used, e.g. to allow browsing and entering a selection in a menu list. They are used
within electrical devices and mostly consist of a lever, which picks up the action
executed by the user and feeds this movement or pressing action towards a sensor.
The sensor acts like a switch and an transmission element like a rocker if further
provided. Due to space and cost constraints, the application flexibility of those
designs is limited. As long as friction within a hinge appears, the lifetime of the
purely mechanical construction is also limited.
SUMMARY OF THE INVENTION
[0003] In accordance with one aspect of the present invention there is provided a control
device comprising a rigid base, a tilting area adapted to move relative to the rigid
base upon exertion of a force thereto, a hinge unit connecting the tilting area to
the rigid base, an input unit connected to the tilting area to apply a force to the
tilting area, and at least one sensor element provided to detect a movement of the
tilting area.
[0004] The invention thus provides a tilting area and a fixed area, the rigid base, and
a hinge unit in between. Accordingly, a force applied to the input unit creates a
relative movement of the tilting area with respect to the rigid base or any elements
associated with the rigid base. The hinge unit allows by its stiffness and/or flexibility,
which can be adjusted by its shape and its material, a deflection of tilting area
towards rigid base. The sensor element picks up the movement from the tilting area
with respect to the rigid base and translates the primary effected physical values
like travel resulting from the movement and/or pressure into an output signal.
[0005] The invention allows the formation of a simple and easy to manufacture and cost efficient
control element. Also, a distinctive determination of multiple grades of a directed
action is possible due to the simple application of a mechanical path of the tilting
area.
[0006] The resulting movement can have x,y,z axis direction or any combination of those.
[0007] The input unit is preferably mounted or fixed to the tilting area.
[0008] Preferably, the rigid base extends in a first plane and the tilting area is provided
to extend in parallel to or within the first plane in a situation where no force is
exerted on the tilting area. Upon exertion of a force thereto the tilting area is
adapted to be tilted with respect to the first plane and then extends in a second
plane not parallel to the first plane.
[0009] A suspension element may be provided to suspend the combination of the rigid base,
the tilting area and the hinge unit.
[0010] Preferably, the tilting area, the rigid base and the hinge unit are integrally formed
with each other and are formed of the same material. This allows the so formed integral
unit to be the carrier for the input unit while at the same time providing an elastic
suspension for a directional operation of the input unit. Only one single element
is needed to provide these functions. This element can be easily and cost-effectively
formed. Moreover, by its integrated provision, the hinge unit is provided frictionless.
The resulting control device is highly reliable due to its frictionless suspension
and its frictionless translation of force or deflection to sensors. Also, the device
is rugged with respect to extreme climatic environments like dust, dirt, humidity
or temperature due to a selection of specific materials and the frictionless suspension,
and frictionless translation of force and/or deflection to the sensor element
[0011] Further, also sensors delivering electrical values may be used and may be formed
contactless thereby further improving the reliability and ruggedness.
[0012] The tilting area, the rigid base and the hinge unit may be formed of steel, stainless
steel, ceramics, PCB (printed circuit board) or plastic. This formation of the tilting
area, the rigid base and the hinge unit as a single element out of one material, standard
materials can be used and even three-dimensional printing can be used to form these
integrated elements.
[0013] In another embodiment, the tilting area, and the rigid base are formed of the same
material like for instance steel, ceramics or plastic and the hinge unit is formed
of a different material like for instance rubber.
[0014] The hinge unit is preferably shaped such that a predetermined flexibility of the
hinge unit is obtained. Thus, through the shape and/or material of the hinge unit,
its flexibility can be defined. The hinge unit may be s-shaped, or meander like shaped
or can have any other shape.
[0015] Preferably, the hinge unit provides a bias force to the tilting area. Thus, the hinge
unit creates a counterforce once deflection or a force is applied to the input unit.
Once an action disappears, the tension respectively the counterforce lets the tilting
area return to its zero position as long as no locking state is provided by any auxiliary
mechanical elements.
[0016] In one embodiment, the hinge unit is provided by the sensor elements itself adapted
to be pressed or moved upon exertion of a force thereto. This allows an even simpler
construction of the control device.
[0017] In one embodiment, the rigid base is formed of plastic and the tilting area is formed
of steel, or vice versa.
[0018] The input unit may be a joystick.
[0019] The input unit may an encoder or a potentiometer or any other input element having
at least one mode of intrinsic operation. This allows the application of even more
functions to the control device.
[0020] In one embodiment, a support element is further provided to support the tilting area.
The tilting area moves relative to the support element. The support element may however
also be part of the tilting area or attached thereto and may move together with the
tilting area with respect to the rigid base or the suspension element. The support
element or parts of it may however also be formed by the surrounding housing of the
apparatus, where the control device is liked to be included into.
[0021] The sensor element may be an optical, magnetic, capacitive, inductive, resistive
sensor element or a voltage and current transducer.
[0022] The sensor element translates an applied force by pressure/force or tension detection
into an output signal.
[0023] The sensor element may be located on any of the tilting area, the rigid base, or
the input unit sensing different movements.
[0024] In one embodiment, the sensor element forms part of the input unit.
[0025] Further, a restriction element may be provided to restrict movement of the tilting
area in at least one of the possible directions of movement. According to the invention,
the desired grades of freedom of the resulting movement can be restricted, which may
be desirable for certain applications.
[0026] In another embodiment, an auxiliary element can be provided connectable to the tilted
area to lock the control device in at least one direction.
[0027] In a further embodiment, a haptic feedback element can be provided connectable to
the tilted area to provide a haptic feedback of movement of the tilting area.
[0028] The characteristics, features and advantages of this invention and the manner in
which they are obtained as described above, will become more apparent and be more
clearly understood in connection with the following description of exemplary embodiments,
which are explained with reference to the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0030] Throughout the following, a control device will be described. The control device
is adapted to detect a movement of its input device along the x, y, z-axis or any
combination of those. The control device translates a directed activity of a user
to an input unit like turning a knob, stick etc. into an electrical value related
to direction of activity.
[0031] Figure 1 is a schematic top view of a first embodiment of the invention. Figure 2
is a side view of the embodiment shown in Figure 1. The control device according to
the invention comprises a rigid base 1b and a tilting area 1a which adapted to move
relative to the rigid base 1b upon exertion of a force thereto. Rigid in this respect
means that the base 1 b is provided unmoveable with respect to the tilting area 1a.
Further provided is a hinge unit 1c connecting the tilting area 1 a to the rigid base
1 b. The hinge unit 1 c allows the deflection of the tilting area 1 a with respect
to the rigid base 1 b. The control device, the rigid base 1 b, the tilting area 1
a and the hinge unit 1 c are in the embodiment shown all of rectangular shape but
can have different shapes as well, like e.g. circular.
[0032] Further provided is an input unit 2 connected to the tilting area 1a to apply a force
to the tilting area 1 a, and at least one sensor element 3 provided to detect a movement
of the tilting area 1 a. Around the input unit 2, the tilting area 1a is provided
surrounded by the hinge unit 1c which again is surrounded by the rigid base 1 b.
[0033] A sensor element 3 is provided to detect the movement of the tilting area 1a. In
the first embodiment, four sensor elements 3 are provided. Two sensor elements 3 are
provided left and right of the input unit 2, i.e. along the positive and negative
x-direction. Two further sensor elements 3 are provided on the upper and lower side
of the input unit 2, i.e. along the positive and negative y-direction as shown in
Figure 1. The invention, however, is not limited to the use of four sensor elements
3. According to the desired functionality of the control device, fewer or more sensor
elements 3 may be provided. The sensor elements 3 are exemplarily and not restrictively
provided below a top surface of a suspension element 10 of the control device and
on top of the tilting area 1 a. Here, the sensor elements 3 are exemplarily adapted
to measure a pressing force resulting from a movement of the tilting area 1 a. However,
the sensor elements 3 are not restricted thereby and can have different functionality.
[0034] In the first embodiment of Figure 1 and 2, the rigid base 1 b and the tilting area
1 a extend in the same plane when no force is applied to the input unit 2. The support
element 4 below the tilting area 1a is only an optional element. It supports the tilting
area 1a. This provides stability and further also allows the provision of a counterforce
against a pressing action in the z-direction of the input unit 2. The input unit 2
could be provided as a pressing knob or stick and the pressing of the knob or stick
along the z-direction can thus be detected. Without the optional support element 4,
this pressing action may not be detectable.
[0035] The control device may comprise a suspension element 10. The suspension element 10
may have a rectangular shape with a top surface 11, a bottom surface 12 and two side
surfaces 13 and may be hollow. On its top surface 11, a hole 14 may be provided to
allow the input unit 2 to extend therethrough. The suspension element 10 may also
be described to have the shape of a rectangular letter "C" lying on its back. Here,
the suspension element is shown as a separate element, but it or its parts can also
be integrally formed by the surrounding housing where the control device is built
into.
[0036] The tilting area 1a in Figures 1-3 extends in parallel to the top and the bottom
surface of the suspension element 10 within the suspension element 10. On both its
lateral ends, the hinge units 1c are coupled to the rigid base 1b. The rigid base
1b is rigidly connected to the suspension element 10. In the embodiment shown, the
rigid base 1b is fixed or pressed between side walls 14 of the suspension element
10. However, the rigid base 1 b may not be a separate element but may be an integral
part of the suspension element 10 itself. In some embodiments described later, the
rigid base 1 b could also be provided by the top surface 11 of the suspension element
10.
[0037] Figure 3 shows the control element of the first embodiment in an actuated state.
A force or an action applied perpendicular, angled or parallel to the axis of the
input unit 2 as indicated by the arrow creates a possible relative movement of the
tilting area 1 a towards the rigid base 1 b. The hinge unit 1 c allows by its given
stiffness or flexibility according to its shape and/or material a deflection, movement
or tilt of the tilting area 1 a towards the rigid base 1b. The hinge unit 1c may be
biased against the tilting area 1 a and creates a counterforce once deflection or
force is applied to the Input unit 2. The resulting movement of the tilting area 1a
can have an x,y, or z axis direction or any combination of those. The sensor element
3 picks up the movement or force of the tilting area 1a towards the rigid base 1b
and translates the primary physical values like travel resulting from a movement and/or
pressure into an output signal. Once the action disappears, the tension respectively
the counterforce lets the tilting area 1a return to its zero position as long as no
lock state is provided by auxiliary mechanical elements as described later.
[0038] In a preferred embodiment of the invention as shown in Figure 4, the tilting area
1a, the rigid base 1 b and the hinge unit 1 c are integrally formed of the same material
thus constituting one single integrally formed element extending in a single plane.
The single element may be formed from PCB (printed circuit board), plastics, steel,
ceramics etc. However, other materials are also possible. This allows a simple and
cost effective manufacturing of the control device according to the invention. Furthermore,
the control element formed thereby is very robust and long-life. Advantageously, the
stiffness or flexibility of the hinge unit 1 c can be defined by its geometry or shape
of this section. The hinge unit 1 c may have a meander shape or may be s-shaped. In
this embodiment, the control element could be formed by 3D printing.
[0039] Thus, the invention may use a single element, for instance a PCB element, where the
input unit 2 is mounted onto the tilting area 1 a being movable towards the rigid
base 1 c of the same PCB.
[0040] The hinge unit 1c between those areas - also consisting of the same PCB - creates
by its shape an elastic suspension of the movable part of PCB. Both areas - movable
and fixed ones - can accommodate any sensor element 3 to pick up the relative movement
between movable and fixed parts of the PCB. The input unit 2, as will be later described,
can also be part of an additional input element like e.g. a potentiometer being mounted
onto tilting area 1a, thus allowing a combined interaction of control activities during
operation. This interaction may be a pushing of the input unit 2 into one direction
(+-x, +-y or combination thereof) and turning the input unit 2 around its own axis.
The input unit 2 can be any input element having at least one mode of intrinsic operation.
[0041] Throughout the invention, the tilting area 1a is can either be in the center or the
outer area of the rigid base 1b. Thus, the input unit 2, a lever, knob, etc. can be
rigidly assembled to the center area of the control device and then the surrounding
outer area becomes fixed. It also can be assembled to the outer area then the center
area of the control device becomes fixed.
[0042] Needed wires to any electrical sensor element 3 can also be fed from the sensor element
3 to an electronic circuitry using the hinge unit 1c without the need of additional
cabling.
[0043] Figure 5 is a schematic top view of a third embodiment of the invention. Figure 6
is a schematic side view of the third embodiment of the invention. In Figure 5 and
Figure 6, the tilting area 1a, the rigid base 1b and the hinge unit 1c are formed
of different materials with respect to each other. In the top view shown in Figure
5, the tilting area 1a, a rigid base 1 b and hinge unit 1c all have a rectangular
shape. Around the input unit 2, the tilting area 1 a is provided surrounded by the
hinge unit 1 c which again is surrounded by the rigid base 1 b. In the side view of
Figure 6 it is visible that the tilting area 1a and the rigid base 1b extend in the
same plane while the hinge unit 1 c is provided coupled to the lower surfaces of the
rigid base 1 b and the tilting area 1 a. The rigid base 1 b and the suspension element
10 may be made of plastic, the tilting area 1 a may be formed by a steel plate, and
the hinge unit 1c may be a rubber cushion. However, other materials are also possible.
However, the hinge unit 1c can also be coupled to the upper surface of rigid base
1 b and tilting area 1 a or upper surface of rigid base 1 a and lower surface of tilting
area 1 b and vice versa.
[0044] In the fourth embodiment of Figure 7, the tilting area 1a and the rigid base 1b are
formed of same material while the hinge unit 1c is formed of a different material.
The hinge unit 1c may comprise springs or rubber cushions etc. However, other materials/elements
are also possible. In the embodiment shown in Figure 7, four springs are provided
along the positive and the negative x-axis and the positive and the negative y-axis.
Also, four sensor elements 3 are provided along the positive and the negative x-axis
and the positive and the negative y-axis. However, the embodiment is not limited thereto.
[0045] In another embodiment a shown in Figure 8 the hinge unit 1c may be provided by the
sensor element 3 itself. The tilting area 1 a is supported on a support element 4.
In a plane of the tilting area 1 a, a gap is formed between the rigid base 1 b and
the tilting area 1 a where in figure 1 the hinge unit 1 c was provided. The tilting
area 1 a may be guided by vertical extensions 15 from the top surface 11 of the suspension
element 10. In the embodiment shown, the elastic suspension and counterforce is provided
by the sensor element 3 itself which may be a spring based tact switch in coaction
with the support element 4.
[0046] Figure 9 is a schematic side view of a sixth embodiment of the invention. Whereas
in the previous embodiments, the tilting area 1a was provided around the input unit
2 and was surrounded itself by the rigid base, here, the rigid base 1 b is located
below the tilting area 1 a, which still surrounds the input unit 2. The rigid base
1b is coupled to the bottom surface 12 of the suspension element 10. Here, the bottom
surface 12 of the suspension element 10 may be provided with a support element 4 to
support the rigid base 1b. The hinge unit 1c is placed exemplarily on the same plane
as the rigid base 1 b and couples the rigid base 1 b to the tilting area 1a. In Figure
10, the same embodiment is shown in which a force is applied to the input unit 2 such
that the tilting area 1 a is tilted with respect to the rigid base 1b placed below
the tilting area 1a and the sensor 3 is activated due to its motion towards the suspension
element 10. In the provided embodiment, the sensor 3 is a pressing switch. However,
any other sensor element can be provided.
[0047] Figure 11 is a schematic side view of a seventh embodiment of the invention. With
respect to the first embodiment, only the input unit 2 is different. The input unit
2 itself can provide an additional grade of actuation. This may be provided by an
encoder or a potentiometer or any input element having at least one mode of intrinsic
operation. The input unit 2 may detect a downward pressing force onto its top surface,
which could be used for a selection of an element in a menu. In order to provide a
counterforce against the pressing force, a support element 4 is provided below the
tilting area 1 a. If the input unit 2 is a potentiometer, also a rotation of the input
unit 2 around its axis can be detected. Thus, the control device is multifunctional.
In this embodiment, a sensor element 3 forms thus also part of the input unit 2 itself.
[0048] Figure 12 is a schematic side view of an eighth embodiment of the invention. The
input unit 2 in the embodiment shown can also pick up indirect actuation which may
result from acceleration, vibration of a mechanical element 20 placed on top of the
input unit 2. In this embodiment, the input unit 2 is not directly accessible by a
user.
[0049] Figure 13 is a schematic side view of an ninth embodiment of the invention. In Figure
13, a restriction element 5 is provided in a direction path of movement of the input
unit 2 or the tilting area 1 a. Exemplarily, the restriction element 5 is provided
adjacent to the input unit 2 and is provided in the example shown to extend in the
horizontal direction. The restriction element 5 is located on the top surface 11 of
the suspension element 10, but could also be formed below the top surface 11 of the
suspension element 10. The restriction element 5 is provided to restrict possible
deflections in one direction. This is done in the embodiment shown by narrowing the
hole 14 formed on the top surface 11 of suspension element 10 into which the input
unit 2 is inserted. This allows to provide a restriction in one direction which may
be necessary for a specific application of the inventive control device. The restriction
element 5 could also be provided to restrict the movement of the tilting area 1 a.
Here, the restriction element 5 may vertically extend from the top or bottom surface
11, 12 of the suspension element 10. The exemplarily provided restriction element
5 of figure 13 fully restricts the movement in the positive x-direction. Therefore,
a corresponding sensor element 3 may be omitted as shown in figure 13.
[0050] Figure 14 is a schematic side view of a tenth embodiment of the invention. An auxiliary
or locking element 6 is provided attached to the inner bottom surface 12 of the suspension
element 10 and also on the bottom surface of the tilting area 1 a. The auxiliary element
6 in the embodiment shown may be formed of magnetic elements. Upon movement of the
tilting area 1 a, the magnet 6a on the tilting area 1 a locks with the magnet 6b of
the suspension element 10. This locking may be overcome by an increased force applied
to the input unit 2. The locking effect allows an output of a constant output signal
for a certain time as long as the lock is not interrupted.
[0051] Figure 15 is a schematic side view of an eleventh embodiment of the invention. A
haptic feedback element 7 is provided to apply a haptic feedback for the selected
activity direction. This could be a detent or a multi-step detent. The haptic feedback
element 7 of figure 15 consists of two parts, an extension element 7a extending from
the tilting area 1a and having a protrusion and an interlocking element 7b with a
plurality of indentations provided to interlock with the protrusion of the extension
element 7a. The interlocking effect depends on the tilt of the tilting area 1 a and
the protrusion may move from one indentation to the other along the path of movement
of the tilting area 1 a providing a haptic feedback of detents.
[0052] Figure 16 is a schematic side view of a twelfth embodiment of the invention. In Figure
16, the restriction element 8 is provided to allow a certain movement in one direction,
but to provide a restriction in that direction beyond the allowable movement. This
may provide a protection or limitation of an impact for the tilting area 1a and/or
the sensor element 3 in case of applying an extensive force or deflection to the input
unit 2. In contrast to figure 13, the restriction element 8 does not fully restrict
the movement in one direction. Therefore, a corresponding sensor element 3 is still
provided.
[0053] Figure 17 is a schematic side view of a thirteenth embodiment of the invention. An
auxiliary element 9 can provide an active acknowledgement of an executed action like
optical or mechanical indicators/actuators from the control device where the actuation
information is fed to a separate element.
[0054] In the embodiments shown, the sensor element 3 may be provided to translate an applied
action or force by a proximity detection, i.e. contactless. This may be based on an
optical, magnetic, capacitive, inductive, resistive detection or by voltage and current
transducers. The sensor element 3 may alternatively translate an applied action by
a pressure or force detection. Here, a spring activated switch could be used. Further,
the sensor element 3 may translate and applied action by a tension detection in form
of a strain gauge.
[0055] The sensor element 3 may also provide partial or full functionality of a hinge unit
1 c as shown in Figure 8. This may be implemented by a counterforce of pressed switch,
which removes the full or partial need for an additional hinge unit 1 c.
[0056] Throughout the invention, sensor elements 3 can be located on at least one of the
following elements: the tilting area 1 a, the rigid base 1 b, the hinge unit 1 c or
the input unit 2 picking up any tension, travel or shift among the respective adjacent
elements.
[0057] The invention has a number of benefits compared to prior art.
[0058] The inventive control device has high reliability resulting from a frictionless suspension
and/or a frictionless translation of force / deflection to the sensor elements by
a usage of contactless sensor elements.
[0059] The control device provides extreme climatic ruggedness against dust, dirt, humidity,
temperature by a possible selection of corresponding materials, a frictionless suspension,
a frictionless translation of force / deflection to sensor elements and the usage
of contactless sensor element.
[0060] Further, a distinctive detection of multiple grades of directed action by the application
of a mechanical path of the tilting area is feasible.
[0061] A flexible application of multiple grades of directed action by a combination of
parts of a singular function like potentiometers, switches to an element having multi-action
either separate or as a combination is provided by the inventive control device.
[0062] Further, the invention is cost efficient by a usage of standard materials and components
like encoders, switches and a few additional manufacturing processes.
[0063] It should be understood that the embodiments shown may also be combined if not excluded
otherwise.
[0064] While this invention has been described in connection with what is presently considered
to be practical exemplary embodiments, it is to be understood that the invention is
not limited to the disclosed embodiments, but, on the contrary, is intended to cover
various modifications and equivalent arrangements included within the scope of the
appended claims.
