Element G: CONSTRUCTION OF A TESTABLE PROTOTYPE

EQUIPMENT

Inventor- the 3D printing software we were trained on
3D printer/plastic- to print a tangible product from the models
Anti-glare Film- this was the anti glare material that was available

BILL OF MATERIALs

Visor: $24.36
Anti Glare film: $28.89
Rubber Bands
Hot glue
Glue gun
Cardboard
CAD models

INCREMENTAL TEST PLAN

Folding- The product can fold up when not in use without being distracting to the user. The product will also fold down and into position to the side of the users head deflecting light away from the user. tested by attaching the visor to the cars built in visor and folding it down and into position. If the product rests between the user and the driver side window, protecting their peripheral vision, the test is passed.
Anti glare- The product will deflect light from the user enhancing their ability to see and drive. Tested by folding into position (down and between the user and the car's driver side window) and shining a flashlight from outside directed towards the user. If the user can still see adequately then the test is passed.

BUILD PROCEDURE WITH Photos

Prototype Build Day 1: On day 1, I took the store bought Visor apart, to recycle the pieces due to little resources. We chose to use the second part of the visor as our main piece. We found a way to cut the visor with short notice, however it was not the best tool, which led to a crack in our plexiglass.

Prototype Build Day 2: On day 2, I attached the extension onto the visor, and noticed the support was not supporting the extension as well as we needed it too. This led us to decide to 3D print an additional CAD model of the same two pieces.

Prototype Build Day 3: On day 3, I attached the second support CAD model, and realized it did not stay was sturdy as possible, therefor I used rubber bands to hold the pieces in place. I then noticed that when folded down the visor's extension went too far to the left, rendering it useless. This led to me gluing a small strip of cardboard to it to keep it from going out farther than needed.

Prototype Build Day 4: On day 4, I placed the anti-glare film over the extension, and folded it up as if it were in a car and out of the drivers view, and the extension fell, this led to placing velcro on the top of the visor and the extension.
