  4. Project Management Our team management was loosely organized. Everyone was a team leader and we all shared an equal share of the load based on our own talents. We very quickly discovered who was good at what an divided the work accordingly. This made for an efficient and pleasant work experience.

  5. Final Customer Needs List

  6. Final Problem Statement The team of first year engineers was given the task of redesigning the electric toothbrush to better suit the needs of consumers. The goal of this project is to contrive a smaller, cost effective device with a longer lasting battery, pleasant appearance and minimal noise.

  7. External Search The team carried out an external search which included a detailed literature review ,a patent search and a benchmarking table . The information gathered through the search gave us a reference point for a toothbrush of our own.

  8. External Search Literature review conducted gave us an understanding of the present models of electronic toothbrushes and helped us incorporate the following features Rotating brush head Slightly bent neck Slimmer battery profile Better ergonomic and aesthetic design The benchmarking table provided our team with further information of their performance levels and market success rates and design shortcomings of the leading producers of electronic toothbrushes

  9. Concept Generation On the left: A sleeker concept Designed to be As close to an ordinary Toothbrush as possible On the right: An ergonomic shape To fit precisely into the hand of the customer and provide maximum comfort.

  10. Concept Generation This Concept showcases the switch/stand Concept. When in a hand, the fingers hold down the switch. When the consumer sets It down, it turns off and stands freely on its wings.
