Applied Design

At the end of this course, the students should be able to: 1. demonstrate proficiency in systematic scientific design methodology; 2. demonstrate creative application of the design process to engineering problems; 3. demonstrate proficiency in design for the manufacture of complete mechanical systems and devices; 4. undertake a group design project; 5. submit reports showing all calculations, justification for choice of design and instructions on detail design, manufacture, testing and use; and 6. demonstrate use and evaluation of a CAD/CAM software package in the actual manufacturing design project.

Scientific Design Methodology: creative application of the design process to engineering problems with emphasis on the manufacture of complete systems to accomplish overall objectives of minimum weight, high efficiency while satisfying the design constraints. An appreciation of the process of engineering design, and of systematic procedures and tools usable in the design process, with particular reference to mechanical systems and devices. Topics include systematic problem definition, search for possible solutions, statistical analysis of stress/strength interference, experiment planning techniques, optimum design for minimum weight and cost, and management of the design process. Design Project: Students will be required to conduct a design project under supervision, using the presented techniques, and taking at least to a workable layout drawing of a device. The design should involve simple mechanical systems (e.g. testing and assembling devices, heat drive, etc.) for a specified duty, analyse its operating conditions and after considering the design criteria, choose between potential solutions. Reports submitted by students should contain all calculations, a comparison of potential solutions, justification for the design finally chosen, and instructions on detail design, manufacture, testing and use. Use and evaluation of several CAD/CAM software packages. Students will gain experience with CAD/CAM software while carrying out an actual manufacturing design project.
