Class Schedule:

Meets for 3 hours of lecture and 1 hour of laboratory each week for 10 weeks.

Computer Usage:

AutoCad, Unigraphics, SolidWorks, Powerpoint, Matlab, MathCad.

Laboratory Projects:

Group Design Project, 1st Phase – the deconstruction and competitive benchmarking of an actual commercial thermo-electro-mechanical device. The testing phase is completed in a laboratory. Group Design Project, 2nd Phase – an thermo/fluid and electromechanical design problem based on the deconstruction phase described above. The testing and comparison takes place in the laboratory.

Professional Component

Contributes toward the Mechanical Engineering Topics courses and Major design experience.

Design Content Description
Approach:

5 design exercises: 3 individual; 2 in groups. At least 1 oral and 3 written reports are required; a final design project report. 1) Group assignments - students explore the design/manufacturing interface using a commonplace device or implement. Encouraged to visit local manufacturers. 2) Design Project, 1st component (in group) – design challenge begins with the deconstruction of an thermo-electro-mechanical device (5 weeks). (Example: deconstruct a hair dryer and determine its fluid/thermal/mechanical performance). 3) New Product Directions (individual) – develop an invention and examine the patent literature. 4) Design Project, 2nd component (in group) – design challenge from the thermo-electro-mechanical systems arena (5 weeks). (Example: design a musical instrument from a hair dryer. 5) Failure Analysis (individual) – uncover a failed device or component and analyze the source of the failure using basic thermal, fluid, vibration, or strength of materials considerations.
