Abstract

This project is purpose to create technical research for undergraduate students which have high potential in technical paper publication. Throughout this project, an existing optical mouse will separated each part purpose to do analysis and to critique the assembly point of view. After done the analysis, by using the Boothroyd- Dewhurst method some of the part will eliminate or reduce and redesign remain part as possible and come out with the some conceptual design. To ensure the purpose is achieved, some of the important element must be consider, there are followed the scope of project such as, literature review of the DFMA. In this project, all the design drawing, drawn by using the CATIA software. Finally, the new design will be compared with the original design from aspect, assembly cost, assembly time, part quantity and design efficiency. Base on calculation, the result had been containing for manual analysis, the percentage of design efficiency is 67.2 %, and for software analysis, the percentage of design efficiency is 71%. For percentage of part quantity, the result is 60% for both analyses. The result for percentage of assembly time is 70.3% for manual analysis and 63.82% for software analysis. Mean while the percentage of assembly cost is 70.3% for manual analysis and 66.7% for software analysis. From the overall result, the result obtained in software and manual analysis was not much different. For example, in result of design efficiency, the different values in manual result and software result for existing design was not much different. For manual existing design efficiency the result is 0.134 and for software the result is 0.1305. This project has shown the correct method to design and analyze optical mouse using Boothroyd-Dewhurst DFMA methodology
