Changing the Mechanical Engineering Design Sequence at XXX University: A Work in ProgressDue to a Summer 2012 conversion of quarters to semester, XXX has embarked on an effort torevamp and enhance its design sequence. This began in the Spring and Summer of 2010 withgraduating student exit interviews, alumni focus groups, and faculty retreats. These culminatedin a modification of the current design sequence at this university. This paper focuses on a newdesign course for second year students admitted to Mechanical Engineering. The primaryobjectives of the course are two-fold: (i) to enhance student’s foundational knowledge, skills,and associated intuition, and (ii) to introduce the students to open–ended design problems. Thecourse is focused on the design and fabrication of functional artifacts. The students will work inteams to construct a compressed–air motor from a kit of parts, most of which will requiremachining to close tolerances before assembly. Then students will have their initial contact withsystems concepts such as control involving, for example, use of a stepper motor to control inletair pressure to the motor. Each team will then design and prototype a device that will be drivenby the output shaft of the motor and which will perform a useful task of the team’s own devising.Students will follow a structured design process while using common design techniques such asPugh charts and Quality Function Deployment charts in their decision processes. Each team willcreate several candidate design concepts, which they will winnow down to a single conceptthrough an iterative process. Two pilots of the new design course will be completed before thesemester implementation. Assessment instruments of the pilots include assignment rubrics,focus groups, surveys, and questionnaires. This paper includes some of the preliminary datacollection and results and issues encountered by the development team.
