Product Designer needed to design special mechanism
Closed - This job posting has been filled and work has been completed.
We have created an electronic unit that transmits a wireless signal when turned on. We wish to embed this piece in an enclosure that incorporates a mechanism to turn on the electronic unit. The mechanism should be designed so that the electronic unit is quick and easy to deliberately turn on. However, the design should also prevent against accidental turn on. Finally, when the mechanism is turned on, it should remain turned on until explicitly turned off.
The electronic unit has the following dimensions: 28mm x 15mm x 4mm [length, width, height]. The enclosure for this electronic unit must be as small and sleek as possible, as it is going to be incorporated into a piece of jewelry. Elegant and aesthetic design is important.
This electronic unit will have two wires that, when connected, turn the unit on. Thus, these leads should be connected when the mechanism is turned on, and otherwise remain unconnected when the mechanism is turned off. If you choose to use an electronic switch to handle this, please see the additional information paragraph.
Additional Information on powering the unit using electronic switch:
If you wish to use an electronic switch to power/unpower the electronics in the mechanism, you may find the following source useful: http://www.omron.com/ecb/products/
For your reference, these switches can be bought in two modes:
Normally Open (NO), where the electronic unit is powered when the switch is being pushed down, and unpowered when the switch is not being pushed down.
Normally Close (NC), where the electronic unit is powered when the switch is not being pushed, and unpowered when the switch is being pushed.
You may find these modes of operation useful when creating the design. CAD files of these switches are available on Omron’s website. Of course, you may use switches from other manufacturers if they better fit your design needs.
