Instructional Methodology for Capstone Senior Mechanical DesignSenior mechanical design - the capstone design course, is always a big event for everymechanical curriculum. Students look forward to it not only because it is a chance to apply allthey have learned in converting ideas into reality through a mechanical design project, but alsobecause they want to conduct a real design in an industrial setting. Students are looking for abridge to help them migrate from an academic environment to an industrial environment. It is abig responsibility for faculty who instruct the senior mechanical design because faculty shouldtry to build a smooth bridge to connect academics to real world situations for students. Someobservations, experiences and options about how to instruct senior mechanical design projectsbased on our Capstone design course - MECH690-Mechanical Design will be presented andshared throughout this paper. Several key strategies for instructing senior mechanical design,based on our senior design examples, will be presented and discussed in detail. For example,one key strategy is how to properly accept or firmly reject students’ design proposals. A gooddesign proposal must clearly describe its application “need”. Any design proposal without aclear applied “need” must be rejected. That every design project must go through all stages ofthe general design process is an essential strategy for ensuring the greatest chances for asuccessful design project. Jumping or skipping some stages of the general design processfrequently causes disaster by abnormally ending the project. Another key strategy is propermonitoring and guidance to the design team. Weekly class meetings and weekly group meetingswith the faculty are a must. The faculty should act like a chief engineer to alter, stop, reject orsuggest a design option or guide the general direction of the design project. One more keystrategy is ensuring students must pay enough attention to general design criteria such as safety,manufacturability & assembly-ability, and economics during the design process. Completion ofthe design project to fabrication of a prototype is not considered the overall purpose of thestudent design experience. Realization of the design project with consideration of safety, ease ofmanufacturing & assembling, achieved at economic price is considered essential for anysuccessful capstone mechanical design project. Finally, requiring an engineering documentationpackage of the design project, including reports and production drawings, is also a key strategy.
