  1. Systematic Design Procedures • Need for Design Methods • Design-by-Drawing • New Methods • Formalize certain procedures of design • Externalize design thinking • Creative Methods Brainstorming, Synetics, Enlarging Search Space, …. • Rational Methods Checklists, Objective Trees, Function Analysis, QFD, Morphological Chart, … Yong Se Kim

  2. Enlarging the Search Space • Random Input • Random words from dictionary, First visual image of TV, … • Why? Why? Why? • Network of Question-and-Answer • Counter Planning • Deliberate Opposite • Compromise Yong Se Kim

  3. Rational Methods Yong Se Kim

  4. Rational Methods • Clarifying Objectives Objective Tree – to clarify design objectives and sub-objectives, and the relationships between them. • Establishing Functions Function Analysis – to establish the functions required, and the system boundary, of a new design. • Setting Requirement Performance Specification – to make an accurate specification of performance required of a design solution. • Determining Characteristics QFD – to set the targets to be achieved for the engineering characteristics. • Generating Alternatives Morphological Chart – to generate the complete range of alternative design solutions, and to widen the search for solutions. • Evaluating Alternative Pugh, Dominic, Objective Tree etc – to compare alternative design proposals • Improving Details Value Engineering, Design for Manufacture – to increase the value of the product to customers while reducing the cost to the manufacturer.
