3D icon for use with a switch and a method of making the 3D icon
An assembly including a three dimensional icon defined within an interior of the assembly; the assembly including a non-moveable switch; a device for illuminating the three dimensional icon, wherein illumination of the three dimensional icon by the device causes the three dimensional icon to be visible on an exterior surface of the assembly.
1. An assembly, comprising:
a polycarbonate substrate layer having a forward facing surface and a rearward facing surface opposite to the forward facing surface;
a three dimensional icon defined within the polycarbonate substrate layer, the three dimensional icon being a three dimensional shape molded in the rearward facing surface of the polycarbonate substrate layer;
a layer of polyurethane applied to the forward facing surface of the polycarbonate substrate layer;
a non-moveable switch;
a device for illuminating the three dimensional icon, wherein illumination of the three dimensional icon by the device causes the three dimensional icon to be visible on an exterior surface of the assembly.
2. The assembly as in claim 1 , wherein the assembly is a portion of a vehicle interior.
3. The assembly as in claim 1 , wherein the device is a light emitting diode (LED).
4. The assembly as in claim 1 , wherein the non-moveable switch is a capacitive sensor integrated with a printed circuit board.
5. The assembly as in claim 1 , wherein the three dimensional shape of the three dimensional icon is a laser drawn three dimensional image within the rearward facing surface of the polycarbonate substrate layer located above the non-moveable switch.
6. The assembly as in claim 1 , wherein the non-moveable switch is integrated with a printed circuit board and the device for illuminating is provided by side firing light emitting diodes (LEDS).
7. The assembly as in claim 1 , wherein the non-moveable switch is a printed touch sensor integrated into a flexible film located on the forward facing surface of the polycarbonate substrate layer that is disposed adjacent to the layer of polyurethane.
8. The assembly as in claim 7 , wherein the flexible film is injection molded with the polycarbonate substrate layer.
9. The assembly as in claim 1 , wherein an area below the three dimensional shape of the three dimensional icon is filled with a clear material.
10. The assembly as in claim 9 , wherein the non-moveable switch is a capacitive touch pad located behind the three dimensional icon.
11. An assembly, comprising: a polycarbonate substrate layer;
an icon sub-assembly inserted into an opening located in the polycarbonate substrate layer, the icon sub-assembly including; a non-moveable switch, a three dimensional icon, the three dimensional icon having a forward facing surface and a rearward facing surface and a three dimensional shape molded in the rearward facing surface of the three dimensional icon and a device for illuminating the three dimensional icon; and
a layer of polyurethane applied to the polycarbonate substrate layer and the icon sub-assembly.
12. The assembly as in claim 11 , wherein the non-moveable switch is formed from a clear conductor that is located on a top of the icon sub-assembly.
13. The assembly as in claim 11 , wherein the non-moveable switch is a sensor ring located about a periphery of the icon sub-assembly.
14. The assembly as in claim 11 , wherein the icon sub-assembly has a frame that surrounds the device for illuminating.
15. The assembly as in claim 14 , wherein the frame includes a flange portion that engages a rearward facing side of the polycarbonate substrate layer about a periphery of the opening in the polycarbonate substrate layer that the icon sub-assembly is inserted into.
16. The assembly as in claim 14 , wherein a flange is located between end portions of the frame and the flange engages a forward facing surface of the polycarbonate substrate layer located adjacent to the layer of polyurethane.
17. The assembly as in claim 14 , wherein the frame is formed from a polycarbonate material.
18. The assembly as in claim 17 , wherein the frame is opaque.
19. A method for forming an assembly, comprising:
forming a polycarbonate substrate layer with a forward facing surface and a rearward facing surface opposite to the forward facing surface;
forming a three dimensional icon within the polycarbonate substrate layer, the three dimensional icon being a three dimensional shape molded in the rearward facing surface of the polycarbonate substrate layer;
applying a layer of polyurethane to the polycarbonate substrate layer;
applying a non-moveable switch to the forward facing surface of the polycarbonate substrate layer; and
securing a device for illuminating the three dimensional icon to the polycarbonate substrate layer, wherein illumination of the three dimensional icon by the device causes the three dimensional icon to be visible on an exterior surface of the assembly.
