P14418: Better Water Maker-Power Generation Unit

1. P14418: Better Water Maker-Power Generation Unit Requirements Purpose The Better Water Maker was developed to disinfect water in nations with high mortality rates due to poor water and sanitation systems. The goal of our team is to provide a low cost, efficient power generation system for the Better Water Maker that does not tire the user while it is fun and easy to use. • Increase ease of use • Reduce cost to target of $75 • Produce power consistently • Designed for Women and children Fig. 1: Previous Design Final Concept Selection Gearbox Electrical Seat and Track • Several designs were analyzed but this design had the best tradeoff between cost, power production, and proven science • Also used the legs as a power source • Three LED user interface • Regulator circuit to protect the bulb in the sanitation system • Mimicked a recumbent seating design • Adjustable gearbox track, that is designed to satisfy heights of women and children • Low cost materials • Increase gear ratio from 1:24 to 1:28 • Change design to accommodate foot pedal • Reduce motors from 4 to 3 to reduce torque • Increase RPM Future Recommendations Conclusion • Not optimal design but… • Testing proved that… • Use motors with same outside envelope, with same power specs, but reduced RPMs • To reduce cost, analyze different materials for several components Our Team (left to right) • Kyle Jordan: Mechanical Engineer • Liz White: Mechanical Engineer • Jacob Kleinberger: Project Manager/ Industrial Engineer • Jessica Fuss: Group Leader/ Mechanical Engineer • Erika Correa: Industrial Engineer • Chris Falanga: Electrical Engineer
