Description:Looking for an engineer that has experience with light guides or light pipes used with LEDs, and that can design a few simple light guides for an electronic device. 3 LEDs - red, green, blue will feed the light pipe. the other end of the light pipe will be visible to the user thorugh a cutout in the enclosure. the user will see this end of the light pipe, which is 2 strips each at .2 wide x 2" long. there may be some curvature to these 2" long strips (maybe a radius of 2.5"). when the red LED is on the strips will light up red. same for green, etc. need to make sure the lighting is continuous (not brighter at one end than the other). Proven experience with LIght pipes is required. $100 for initial sketch and background proving that this design will work. Further work would then be given to winner to develop the concept into a injection molded part. Good Luck and I look forward to working with you.
Wants:light pipe design must be able to be converted into an injection molded light guide with a cost of less than 1.00 per part at 1000pc lot size. needs to be assembly sketch with lightpipes and LEDs, and part sketches for each light pipe. see attached pg2. sketch with dimensions, material, and engineering proof (design guides, other similar products, prior experiences, etc) that the concept will work. Bonus points will be given to designs turned in by 9/21/2016
Additional InformationAny design must inlcude the following for consideration: 1) the concept must include sketch/model of the actual light guides with dimensions, and any surface treatments etc. and sketch/model of the assembly showing how they are held to circuit board and housing.
#6 Lightpipe by Adam
I recommend that you hot stamp the top of the lightpipe as opposed to pad print. The ink used in pad printing tends to no adhere very well to glossy surfaces and has a high scrap rate. The other option is in-mold decoration insert for the surrounding black area. Note: this is not real world light emission, it's just a rendering. You would need Ray Tracing software to determine how the light pipe performs.

Design should be of a liver shell. It should be an anatomically accurate model that can be printed if needed to. The inside should be hallow and the liver should include a hole on top where the hyper-vein would normally be and a hole on bottom where the vein would leave. The liver shell should be a 2 piece design that can be clicked/ screwed together to symmetrically put together the 2 halves. http://www.exchange3d.com/3D-Model-of-Liver-Anatomy/prod_28235.html#preview A more simplified version of this will be perfect.

Outdoor TV Enclosure
Design an outdoor TV Enclosure for 32" flat screen TV to be used outdoor such as backyard, pool, or cafeteria. - Inside the enclosure will hold flat screen TV with dimension of 30" x 18" x 2" (W x H x D). Dept can be extended if needed. - TV must be safely secure inside the enclosure when not attach to the VESA Wall mount - Must be able to mount with VESA Wall mount standard of 200mm x 200mm - Water resistant but does not need to be completely waterproofed - Have a cooling system, either ventilation for airflow (Fans) or cool down liquid (Freon) - A sound bar will be located in the bottom of the enclosure - Would be nice if the enclosure has feet that can be pushed in or pulled out when place on the ground to keep it balance.
