P R O B L E M S T A T E M E N T

The redesigned electric toothbrush needs to focus on portability, mostly being smaller in size. Durability and user friendliness also need to be considered. Powerfulness should also be looked into but is the least important need to focus on. The new problem statement expands the list of needs and adds ones that were not originally considered.

EXTERNAL SEARCH1) Patent Search: A search was performed to find available patents relevant

to our customer needs to get an idea of what technology was available and decide how practical our designs were

2) Benchmarking: Features of our toothbrush were measured against the same features in toothbrushes made by competitors.

3) Project Dissection: We measured the noise, power generated from the battery, and battery life of the toothbrush.

4) Design Target: From our external search we acquired knowledge of different designs from various patents, we established what the customer needs, as well as finding different designs to compare to each other.

CONCEPT GENERATION

Fitted grip that conforms to shape of the fingers

MORPHOLOGICAL CHART

CONCEPT SELECTIONCRITER IA

Selection criteria was based on a combination of all four of the team’s Pugh charts, as well as logical reasoning to decide whether the concepts together would be applicable in a practical sense.

FINAL DESIGN

HOW IT WORKSF I N A L C O N C E P T

S E L E C T I O NBrush Head: One circular

spinning head, above lateral motion square bristles, with harder plastic on the sides

Body/Grip: Indents in handle to match finger position for a fitted handle

Power Generation: Detachable button batteries with separate charging base

Energy Mechanism: Spinning shaft to oscillate brush head

H O W

The motor is located inside the handle above the batteries, this is then connected to a vertical shaft which is connected to a circular spinning brush head as well as a lower square brush head that vibrates side to side, just like the original toothbrush. The motor gets its power by three rechargeable button batteries below inside the handle which has rubber finger placement areas for increased grip and comfort while brushing.

CONCLUSION• This project was very insightful into the design and

improvement process that people and companies go through to create new and more capable products for consumers to use. We worked really well together as a group and took advantage of each of our strengths to make up for each of our individual weaknesses. As a whole this project taught us how to work as a team to successfully create a possible functioning product. Our final product meets every customer need to the highest possible degree. In order to accomplish this goal we have pulled from previous designs as well as created some of our own. Some of our own unique designs are a completely rubber grip with indents to conform to your fingers as well as rechargeable button batteries to aid in weight reduction. In the end we have created a piece of machinery that further improves the cleaning of teeth and if put into production would benefit the society as a whole.
