Design builds on knowledge of the engineering design process, encompassing specification, analysis, creative thought, and selection from alternative designs. Students will be equipped with the knowledge to write basic design specifications for a product or task. Students will undertake analytical calculations to design and/or select machine elements and apply selection methodologies to compare different design proposals. Students will also be tutored in the requirements for safety, ergonomic and environmental issues. They will expand their concurrent engineering knowledge into the areas of design for manufacturing, and assembly etc.
Barriers to creative thought:
Definition of mental barriers. Classification of mental barriers. Puzzles which highlight barriers.
Design process review:
General structure of design specifications. Statement of problem, “must requirements”, “want” requirements, criteria for excellence.Setting target and final specifications, needs-metrics matrix.
Concept selection:
Concept screening, selection matrices, concept rating, concept ranking.
Engineering Machine Element DesignSelection:
Requirements for engineering design calculations, industrial standards, safety factors, sizing structural elements, sizing welded joints. Component selection: threaded fasteners, locking devices, bearings, seals. Using web based supplier data
Safety requirement:
Protection of personnel, mechanical hazards, non-mechanical hazards, risk assessment. Protection of equipment, mechanical safety devices, thermal and electrical safety devices. Irish Factories Act, EU machinery directive, US OSHA requirements, safety standards and compliance.
Ergonomics:
Deifinition of ergonomics, the human-machine relationship, human factors, instrumentation and control layouts, machine construction, anthropometric data.
Design for manufacturing and assembly:
The DFM method, minimising costs, use of standard components, redesign to minimise processing, integration of parts, minimisation of assembly directions, self-aligning and self locating parts, minimising complexity. Design for Environment (DFE).
