Problem-solving Methodology for Engineering Design (cont-2) • Paradox – Design knowledge grows as design freedom diminishes [Source: Dieter & Schmidt 2013] 11
Considerations of Good design Performance Requirements Functional Requirements- for components, sub-assemblies, assemblies Aesthetic Requirements-shapes, size touch and feel Environmental requirements -operations conditions e g temperature, humidity, dirt, vibration, noise, corrosive conditions energy conservation chemical emissions (hazardous) waste production, recycling requirements Human Factors Cost, e.g. price-performance considerations Regulatory and Social Issues Code of ethics require engineers to protect public health and safe Regulating agencies include: Occupation, Safety and health Council, Consumer Council, Environmental Protection Department, etc
Considerations of Good Design • Performance Requirements – Functional Requirements – for components, sub-assemblies, assemblies – Aesthetic Requirements – shapes, size, touch and feel – Environmental Requirements – operations conditions, e.g. temperature, humidity, dirt, vibration, noise, corrosive conditions, energy conservation, chemical emissions, (hazardous) waste production, recycling requirements – Human Factors – Cost, e.g. price-performance considerations • Regulatory and Social Issues – Code of ethics require engineers to protect public health and safety – Regulating agencies include: Occupation, Safety and Health Council, Consumer Council, Environmental Protection Department, etc. 12
Considerations of Good Design(cont) Design review Vital aspect of the design process Retrospective study of a design up to that point in time Systematic method to identify problems with the design determining subsequent courses of action, initiate action to correct problem areas
Considerations of Good Design (cont) • Design Review – Vital aspect of the design process – Retrospective study of a design up to that point in time – Systematic method to identify problems with the design determining subsequent courses of action, initiate action to correct problem areas 13
Computer-Aided Engineering Engineering drawing, facilitating visualization, supported by computer graphics and modeling, e. g. AutoCAD, Solid Works, etc Spreadsheets and mathematical tools e.g. MatLab, Mathematica, etc Enabled concurrent engineering design to minimize time -all aspects of the design and development are represented in a closely communicating team
Computer-Aided Engineering • Engineering drawing, facilitating visualization, supported by computer graphics and modeling, e.g. AutoCAD, SolidWorks, etc. • Spreadsheets and mathematical tools, e.g. MatLab, Mathematica, etc. • Enabled concurrent engineering design to minimize time – all aspects of the design and development are represented in a closely communicating team, 14
Engineering Project Management Mastery of engineering specialty no longer enough Project success requires collaboration across technical disciplines, organizational elements stakeholder interest Must think of a project as a cohesive whole and not separate parts
Engineering Project Management • Mastery of engineering specialty no longer enough • Project success requires collaboration across technical disciplines, organizational elements, stakeholder interest • Must think of a project as a cohesive whole and not separate parts! 15
