2.  Problem Statement  Conceptualization: assessment of customer needs and the resulting weight of importance  Preliminary Design: brainstorming, sketches, re- design concepts  Detailed Design: CAD drawings, detailed sketches and dimensions  Production: bill of materials, engineering analysis

4. 1. Appropriateness for children 1.1 Color schemes 1.2 Lightweight 1.3 Music playback 1.4 Timed operation 2. Battery Life 2.1 Re-chargeable battery 2.2 Stand that charges battery 2.3 Battery indicator 3. Adjustability 3.1 Varying speeds 3.2 Interchangeable heads 3.3 Flexible head/neck 4. Efficiency 4.1 Easy maintenance 4.2 Uses own charger 4.3 Operates for exact period of time Retails under $15

5.  Focus our goals on our target consumers, children ages 4-8.  Based on our assessment of the most valuable customer needs, we must refine our concepts to gear our design towards appropriateness for children and efficiency.  Our toothbrush will have design features such as a timed song, a re-chargeable battery, and a functional stand to accompany our toothbrush.

6. The 5 most important re-designed aspects of our toothbrush included:  Timed song  Re-chargeable battery  Bristle structure suitable for children  Ergonomics for children  Tongue scrubber

7.  Timed Song: Button that plays music for 2 minutes (the amount of time which should be spent brushing teeth)  Re-chargeable battery built in to bottom which can be docked in the docking station that is included in our toothbrush

8.  Bristle structure is small and closely knit to better accommodate the size of children’s teeth.  Reduced overall size to account for the size of a child’s hand. The handle is ergonomically friendly and comfortable.

9.  Back of the neck of the brush also serves as a tongue scrubber to eliminate bacteria on the tongue.

19.  Our problem statement originally estimated a retail cost of under $15.  In the bill of materials we calculated a per unit production cost of $7.69.  If we charge the projected $15, we would make a profit of $7.31, minus the cost of shipping and packaging.  For these reasons, we feel that the toothbrush’s cost suits the demand of customers, and has a reasonable cost of production.

20.  We as the united team of America feel that we have successfully redesigned an electric toothbrush to fit the needs of children from ages 4 to 8.  Redesign: Cost effective Timed song Re-chargeable battery Charging stand  We were able to incorporate our ideas and concepts into a ergonomic, cost-effective, and functional design.
