  7. Revised Problem Statement After having assessed the niche “green” market, the design team has identified the key consumer demands to be included in the final concepts of the electric toothbrush redesign. Ultimately, we will employ these demands in order to produce a final product that is more sustainable with regards to both customer satisfaction and environmental conscientiousness. In particular, based on the assessment of the market demands, the project will proceed with particular emphasis on the aspect of quality, namely effectiveness, the category and sub-category of which were proven to be the most critical features according to the consumers surveyed.

  8. Benchmarking/Patent Searches We based our searches on three criteria; Cleaning, Packaging, Aesthetics. We researched different companies to see what patents and designs they already had on the market.

  9. Benchmarking/Patent Searches: The Gillette Company US 7, 636, 977 B2 Jan. 26, 2010 US 3,220,543 Nov. 30, 1965

  10. Benchmarking/Patent Searches: Colgate-Palmolive Company US D476, 157 S Jun. 24, 2003 US D475,529 S June 10, 2003

  11. Benchmarking/Patent Searches: Phillips Company 5, 836, 030 Nov. 17, 1998 US 6,463,615 B1 Oct. 15, 2002

  18. Energy Mechanism for Brush Head Concept 1: Has jet stream of water to wet the toothpaste. None of the bristles rotate Concept 2: One of the bristles rotate in a circular motion while the other set of bristles move in a lateral motion. Concept 3: The brush has toothpaste dispenser built into it.

  37. How Does it Work? Our finalized product is designed to eliminate the complications associated with electric toothbrushes. • Activation begins after pressing the on button, and activity concludes either after 2 minutes or after the off button is pressed. • Simultaneously, the brush heads work together in order to eliminate plaque from teeth. -One rotational and one linear moving head will ensure that tooth cavities will be penetrated and a necessary surface area can be covered. -They are also set at a slight angle to increase penetration • Power is generated from electrical power source. -Toothbrush charges while sitting upright in a charging station.

  38. Final remarks • Does final product address customer needs? • Comfort • Environmentally sound • Convenience • Quality • Durable replacement parts • Mechanically durable • Lasting charge life • Effectiveness
