5. Hierarchal customer needs Revised problem statement After some thought, our team has decided upon using a more energy efficient approach to our toothbrush. Although it seems to be lesser in importance to other factors such as portability or safety, it is a large issue within today’s society. In reference to the factors considered more important by the consumer, they have already been considered. Other companies have created very portable, user friendly, safe toothbrushes for the general population. Using the ideas created by other firms, we can focus much of our attention to the creation of a more efficient toothbrush. Ideas to be considered are those involving rechargeable batteries (for the main point is to avoid the use of disposable batteries), a non-bulky/non-cumbersome device, and possible ways to conserve the rechargeable battery. • Portable • Lightweight • Wireless • Recharge station • User Friendly • Good grip • Left/right handed • Quiet • Aesthetically pleasing • Sustainability • Low output • Rechargeable • Durable • Strong bristles • Energy return • Cost effective • Low-cost materials • Use as little as possible • Keep toothbrush small but usable • Replaceable brush heads • Safe • Sealed off electric compartment • Bristles are strong but not too stiff • Environmentally friendly

7. Generated Concepts – Energy Mechanisms for Brush Head • Concept 1 • Oscillating brush head rather than complete rotations • Concept 2 • Magnetic generator core to increase charge time • Concept 3 • Oscillating bristles for added efficiency

8. Generated Concepts – Energy Mechanisms for Brush Head • Concept 4 • Different brushing modes • Clean, Whiten, Gum Care, Sensitive Teeth, Polish, etc • Concept 5 • Multi-coloured bristles that reflect signs of exhaustion/time to change brush heads

9. Generated Concepts – Power Generation and Power Accessories • Concept 1 • Slow ramping up strength over a number of sessions to ease electric toothbrush’s induction • Concept 5 • Auto-off mechanism after a specific period of time (More than 3 minutes) • Concept 6 • Timers • Overall 2 minute • Specific 30 seconds
