Electric Toothbrush Project Matt, Will, Yousef, Sam October 8, 2012
Project Outline• Test and research Oral-B toothbrush• Dissection and analysis of
toothbrush• Product and patent research • Surveyed customer wants and
needs• Concept generation and selection • Benchmarking of Ideas
Project management
• Google docs• Distributed the work load • Communicated through Email and Text
Messaging• Collaborative design effort
Consumer Needs Revised Problem
Statement
• Develop a toothbrush that is more appealing toothbrush that uses more environmentally friendly plastics. The toothbrush should also be softer and more comfortable to use.

Brush Head Design (form and function)
1. Different Size and Shape Bristles, tongue scraper on back, Rotate different directions
2. Two circular bristle heads, all the same size.
3. Three sets of bristle sizes and shapes that rotate the same way
4. One circular head that rotates
5. Flat brush with bristles on either side that rotate oppositely
Human Factors Body Design (Form)
1. Inverted cone, base comfortably molds to hand
2. Flat base, slowly decreasing in size as you move up
3. Circular base, uniform without
4. Flat base, slowly decreases in size but not as drastic as idea 2.
Energy Mechanism for Brush Head (function)
1. Spinning shaft then a belt attaches to spin the brush head
2. When the motor opens he tube moves 180 degrees to the head component . This moves one side of the brush causing rotation
3. Motor makes a revolution to wind up spring then releases in an oscillating motion
Power Generation and Power Accessories (function)
1. Induced by Magnetism
2. Removable and Rechargeable batteries
3. (top picture)A/C Outlet
4. (bottom picture)Solar Panel that hooks into the toothbrush
5. AA battery operated

Final Design
How does it work?• The head of the toothbrush oscillates. This occurs
because the motor drives a spring to create as much potential energy as necessary.
• The battery is removable and rechargeable. This is a sustainable object because it will not deplete or run out as long as a current is running through.
• The head of the toothbrush can be removed for cleaning.
• The compartment under the head stores the battery and the wiring.
• When a consumer holds the toothbrush their number one thought will be comfort. They will also have a great ease of use turning it on and off.
Customers Needs vs. Final Project
• We can support this through the Facebook survey we conducted• Using the survey we were able to eliminate the factors
customers don’t care about and implement the ones that they do
• Important factors included: gender, bristle type, style, price range, appearance and importance of hygiene.
