UH Capstone - Team 10

Blog 4      During the period of November 11 to November 25 the team worked mostly on generating a production plan. This involved sourcing buyout materials, tabulating a lead time for ordered parts, outlining the manufacturing process, and exploring potential places to execute manufacturing processes.      Table 1 shown below shows the compilation of the research and includes the cost of the items including tax, its purpose, and the vendor the team has identified. Table 1: Items needed for Manufacturing Process       Table 2 shown below shows the manufacturing processes the team has identified that will be needed to build the prototype. For each process, the expected time duration has also been identified and as a whole the manufacturing process is expected to take 64 days from start to finish. Table 2: Estimated Time for Each Manufacturing Process Other details in the manufacturing process have also been decided by G10 which includ...

Blog 3  Team 10 has been working on designing a casing for a wheelchair motor that waterproofs and cools it. For the duration period from October 28th to November 11th, the team has completed its second milestone which was performing the analysis for simulated models and entered its third milestone which is generating a production plan. The work completed for the second milestone specifically includes performing the heat transfer analysis for the fins and performing the pressure calculations for the seal. For the third milestone, the team has started with identifying all the potential materials that will be required to build and install the casing. When the team performed heat transfer calculations for fin dissipation, we realized that the initial constraint of keeping the casing exterior below 44°C was unrealistic due to the casing's low Biot number of roughly 0.003. The casing's extensive surface area compared to its volume, coupled with high thermal conductivity, results in ...
