Current rear view mirrors systems for bicycles are clumsy, unattractive, poor quality, too expensive, or have a small viewing range. Our solution is to create a low cost alternative that requires no power to operate, and attaches to any helmet.

Green Process Design For Disassembly Recyclability No Power Input Env. Friendly Materials Environmental Considerations Fog / Rain Resistant Withstand Elements Ability to block out Sun Doesn't Increase Wind Resistance Marketability Inexpensive Easy to Store Aesthetically Pleasing Colors Shape Customizable Ergonomics Comfortable Light Weight Safe to Ware Functionality Doesn’t Compromise Helmet Integrity Adjustable w/o Tools Holds Mirror Orientation Adjustable w/o Tools Provides Wide Viewing Angle Detaches from Helmet Adjustable Mirrors Clear, Correctly Oriented Image Attaches to Multiple Types of Helmets Durable Minimizes Obstruction to Forward view

Customer Needs Team’s Evaluation 1. Safe to wear9 2. Provides a wide angle view behind the cyclist9 3. Holds mirror orientation as set by user9 4. Minimizes obstruction to the cyclist’s forward field of vision 9 5. Attaches to a typical helmet without compromising the helmet’s integrity 9 6. Is lightweight and comfortable to wear9 7. Is durable9 8. Provides a clear, correctly oriented image9 9. Is adjustable to provide optimal view for the rider9 10. Is inexpensive ($10-20) for the consumer3 11. Detaches from the helmet3 12. Can be adjusted without the use of tools3 13. Requires no power input3 14. Is aesthetically pleasing3 15. Refrains from significantly increasing wind resistance1 16. Is fabricated in an environmentally friendly way1

IDRisk ItemEffectCause Likelihood Severity Importance Action to Minimize RiskOwner 1 Improper mirror orientations and alignment. Image may be inverted, out of focus, or the projected image may not line up with target. Lack of optics experience within the team 339 Research optics, determine faculty and other experts who can assist with optical design. Martin Savage 2 Improper structural design. System may not be structurally sound, natural frequency may pose stability issues. Lack of vibration experience within the team 339 Research vibrations, determine faculty and other experts who can assist with structural design. Olivia Scheibel 3 Exceeding the desired manufacturing cost. System will be unable to be manufactured within desired price range. Cost of materials to build system 3 26 Research lower cost alternatives for system components. Zachary Kirsch 4 Unable to adhere to NHTSA standards Prototype unable to be manufactured for retail Strict standards conflicting with stability needs Be knowledgeable of applicable standards.
