  1. Device to Prevent Clogging of Shower Drains Team Members: Linh Bui, Alicia Ader, Joe Wagner, Jeffrey Chae, Chun Chan, Won Seok Choi Advisor: Dr. Grace Hsuan

  2. Problem • Shower drains are often clogged with long strands of hair http://www.famousmisteredwards.com/edwordz/images/bathroom/03_24_drain.jpg

  3. Problem • The clogged location is not easily accessible http://www.cheap-rooter.com/images/bathtub_shower.jpg - edited by Linh

  4. Objective • Find a solution to remove hair from shower drains • Environmentally friendly • Low Cost • Low Maintenance • Easy to Use

  5. Research • Shower drain structure • Filter solution • Hair properties • Chemical solution • Design of device • Installation of the device

  6. Existing Solutions • Snake- plumber tool • Drain-o • Mesh filter http://www.geardiary.com/2007/02/06/the-flexisnake-hair-clog-tool-review/ http://www.made-in-china.com/servlet/image?compatible=true&tid=2&fid=0&lan_code=0&cache=1&id=EiTawytrvQhA

  7. Chemical Solution • Find a chemical that cleans drains easily • Research previous products to find basic chemicals • The chemical solution involves too hard to create and may not have beneficial affects for the environment • Research the element responsible for breaking down hair in the drains and state that we could increase the amount of that element in our chemical solution, but the effects of it on the environment eliminated it from our choice

  8. Chemical Solution • Cons: • Damages the environment • Causes chemical hazards • Pros: • Easy to use • Somewhat cost efficient

  9. Filter Solution • A two level filter • Face plate guards large objects • Lower level has wires weaved into a basket to trap hair http://www.made-in-china.com/servlet/image?compatible=true&tid=2&fid=0&lan_code=0&cache=1&id=EiTawytrvQhA – Edited by Linh

  10. Filter Solution • Pros: • Easy to use • Cost efficient • Effectively trapping hair before they enter the drain • Cons: • High Maintenance • Health hazardous

  11. Best Solution • Created to cut hair into finer pieces • Constructed with non-corrosive materials • Located above the p-trap • Powered by electricity • Operated by a manual switch

  12. Device Prototype • Attached razor blades placed 5mm apart • Made from one of the strongest stainless steel, Type 301 • The motor is placed outside of the chamber Created by Won Choi

  13. Device Prototype • Side view of the device attached to the p-trap • Bottom consists of a steel plate to act as a cutting board • Recommended replacement every three years Created by Linh Bui

  14. Final Device • Interlocking rectangular teeth mechanism • Stretching hair until exceed stress/strain point • Recommended replacement every five years

  15. Final Device • Various views of the final device • The blades are attached to the piston • O-rings on the piston prevents water leakage Pictures by Won Choi

  16. Final Device • Device attached to the p-trap Pictures by Won Choi

  17. Final Device • Front view • The shaft travels in a circular motion Picture by Won Choi, Animated by Linh Bui

  18. Final Device • Cons: • May require professional installation • Pros: • Minimal Maintenance • Environmentally Friendly • Durable for five years

  19. Summary • Shower drains are clogged by long strands of hair • Existing solutions are either ineffective or require unsanitary processes • Best solution to solve the problem: mechanical device

  20. Acknowledgment • Dr. Grace Hsuan – Guidance • Jay Bhatt – Project researching • Young Choi – Assisting device graphics
