Final Presentation
The Reflected Light Bumper was a product designed to improve transportation safety at Purdue University. The prevalent issue my team and I decided to tackle was the poorly lit bike lanes around campus, which resulted in __ accidents yearly. Our solution was a rounded speed bump illuminated by LED lights and reflective tiles bordering the bike lanes to light up the roads and provide a physical barrier between pedestrians and bikes.
Process
Process
Identified problems in Purdue campus transportation
Decided to solve accidents caused by dimly lit bike-lanes
Brainstormed product that provided illumination and a physical barrier for bike lanes
Researched and calculated costs of product using different materials with Microsoft Excel
Used Weighted Decision Matrix to determine best solution
Designed CAD and found parts on McMaster-Carr to design prototype
Iterated designs based on teacher feedback
Created pseudo code to explain process
Recorded all data and processes in a final Technical Brief on MS Word
Finalized design based on peer and teacher feedback: decision to use both LEDs and reflectors to optimize costs and illumination, using both an intrinsic light source and feed of bike lights.
Created video presentation to advertise product
Iteration 1: Simple LED light inside bumper
Iteration 2: Reflective tiles inside bumper
Iteration 3: Combination of both LED light and reflected bumper
