|After extensive use of Google's patent search we found five patents that have innovative ideas that we felt we could incorporate into our design. During concept selection we decided to incorporate the gear configuration from patent #7234187. In our old design the drive shaft spun the plastic head back and forth very rapidly. This caused excessive noise because the drive shaft struck the plastic head every time it changed direction. By incorporating the gear system from the patent, we let the head maintain continuous circular motion and thus minimized the noise from that connection. We will have to draw up a licensing agreement with Church Dwight Co., Inc.|
|Before beginning any dissection processes, the child’s electric Colgate toothbrush, model #2506VB, was first compared, or benchmarked, against existing market competition. The following House of Quality summarizes the results pictorially. The challenge lies in integrating all modifications to produce an overall better product at a competitive price. By reviewing the House of Quality, each function and component of our exisintg toothbrush could be assessed and compared to that of the competition. The assesment allowed for a more focused redesign on modifications to consider.|

After analyzing benchmark research and considering the intended market, it seems the Crest SpinBrush Kids is the main our main competitor. The Crest SpinBrush Kids is marketing towards children while doing comparably well on specific criteria. The other electric toothbrushes on the market target adults and are therefore not a concern when considering the aesthetics of the electric toothbrush redesign.
To gain a better understanding of the product, the child’s electric Colgate toothbrush, model #2506VB, was dissected. Before causing any permanent damage, all removable parts were first removed for observation to discover any possible improvements. Parts #1 -#5 were all removable without causing permanent damage to the product.
After recording weights, dimensions, quantities, and part functions within the toothbrush, it was necessary to make irreparable damage to further analyze the functions of non-removable parts within the toothbrush. Using a metal saw, the toothbrush was bisected. The masses, dimensions, and internal functions and placement of the otherwise non-removable parts were recorded. By analyzing flaws of internal components, the observations could be utilized for further concept generation of a product redesign.
