Mechanical Engineer to develop light guides or light pipes used with LEDs

Contest Ended, Winner(s) have been selected.
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
Software:
  1. SolidWorks
Additional Information
Any 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.

There will be issues with a company logo that is not one contiguous cutout. Mute button needs further clarification.

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.

Any 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.

I would recommend a light pipe that lights up the entire Square that company name is on, and then company name is just pad printed in Black Ink. Also, you are correct. There will be a mute button on the printed circuit board. At this point we can use any button. Feel free to recommend any button and light combination.

The company name must be one continuous opening, so letters "A", "O', "D" etc. are not feasible as a cut-out for the lightpipe on the top housing.

What feature on the board actuates "mute on", "mute-off". Typically a button such as this is a separate molded part with a small light pipe inside along with a spring and features on the housing to accommodate it.

A complex helix for visualising a pedagogic hypothesis
The spiral of learning (Kolb & Kolb) is a simple helix visualising the learner's progress. I need to visualise a more complex spiral. Turns on this helix are circular. Each turn represents an interaction between teacher and learner. This helix contains 1 grand turn. A grand turn contains at least 3 smaller turns. This creates a turn complex. Each turn achieves a small or large rise on the z axis depending on the diameter of the turns on the x and y axes. In elevation view the turn complex should have a stepped appearance due to the presence of the smaller turns, with the lowest steps at left and the highest at right. The idea to be communicated is that the larger turns contain at least 3-5 smaller turns. Each turn achieves a small increase in z-height as the learner exits the turn, like freeway traffic using a cloverleaf junction. Multiple interactive turns aggregate to a large gain in z-height. In the attached illustration, the largest loop should be understood as not a part of the visualisation. I would like to see two variations of the design: (1) smaller turns ranged on outside of grand turn diameter (2) smaller turns ranged on inside of grand turn diameter.

J-shape
3D modeling of a J-shaped massage tool, much like a Theracane only smaller in dimensions. The tool should be modeled as close as possible to the attached images. The straight portion of the J-shape is approximately 10 inches long and 3/8in in diameter. The hook portion of the tool should form an approximately 180 degree arc and terminate in spherical end of 9/16in diameter. The handle, at the top of the J-shape, should be approximately 3/4in in diameter. The attached jpg images are of the actual tool that I would like modeled and should give you a good idea of it's dimensions. The png file should also provide a good reference. Thanks.
Waterproof Air monitor for drones
Hi, We need a waterproof air monitor for our drones, which has enough airflow to detect particulates, gasses and other pollutants. And has no water ingress. The enclosure needs to be made from plasics, ABS of PLA, and there has to be an atenna for a LoRa module an arduino and batteries. The sensors will be placed directly onto the arduino.
