The Product Design Process (Dieter: Chapter 1)
To design is to create something that has never been, it is frequently said that design is the essence of engineering. Design establishes and defines solutions to and pertinent structures for problems not solved before, or new solutions to problems which have previously been solved in a different way.
Importance of Product Design
The real key to world-competitive products lies in high-quality product design. Decisions made in the design process cost very little in terms of the overall product cost but have a major effect on the cost of the product. Quality cannot be built into a product unless it is designed into it. The design process should be conducted so as to develop quality cost-competitive products in the shortest time possible.
The Design Process
Design is a sequential process consisting of many design operations. The design method starts with knowledge of the states of the art; identification of need; then conceptualized as some kind of model; doing feasibility analysis; and production phases.
A Problem solving methodology consists of: Definition of the problem; Gathering of information; Generation of alternative solutions; Evaluation of alternatives; and Communication of the result.
The morphology of design that represents a complete design process consist of: 1. Conceptual Design; 2. Embodiment Design; 3. Detail Design; 4. Planning for manufacture; 5. Planning for Distribution; 6. Planning for Use; 7. Planning for Retirement of the Product.
