Hierarchal customer needs 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 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.
