  2. Characteristics of Successful Designers • Successful designers (ones producing better quality solutions to given design problems) are those who: • Clarify requirements (objectives, functions, constraints, etc), by asking questions related to the problem under consideration. • Search actively for information pertaining to their design problem. • The state of the art in the field of the problem under consideration should be reviewed through all possible means such as books, handbooks, journals, printed leaflets of manufacturers, internet, consultations with experienced personnel, private communications, etc. • Detach themselves from fixation on early solution concepts. • Produce variants that influence their design problem. However, they periodically assess and evaluate in order to reduce the number of possible variants.

  3. The Design Process • The simplest Design Process Can be modeled by four stages (see Fig. 9): • Exploration • Generation • Evaluation • Communication • Elaboration on the four-stage model can be simulated by the model given in Fig. 10 • Exploration: Need + Analysis of Problem + Statement of Problem • Generation: Conceptual Design + Selected Schemes • Evaluation: Embodiment of Schemes + Detailing • Communication: Further Detailing + Working Drawings, etc

  4. Analysis of the Problem • Analysis of problem (in Fig. 10) • Output of the Analysis is a statement of the problem that can have 3 elements: • A statement of the design problem proper (brief) • Constraints on the solution, e.g. codes of practice, customers’ standards, date of completion, etc. • Criterion of excellence to be worked two, e.g. reduce cost and keep high quality.

  5. Fig. 10 & 12 Embodiment of Schemes • The design schemes (that have been generated in the conceptual design phase, Fig. 11) are worked up in greater detail and one final choice between these schemes is made. • There should be a great feedback from this phase to the conceptual design phase.

  6. Conceptual Design (Fig. 10) • It generates broad solutions in the form of schemes (alternatives). • The selected schemes/scheme have/has to be worked up in greater detail (embodiment of schemes) and one final scheme has to be selected. • Detailing of the selected scheme finalize large number of small but essential points.

  7. Design Procedures • 7-Stage Design Procedure (figs. 10 & 21): • Clarify Objectives • Establishing Functions • Setting Requirements • Determining Characteristics • Generating Alternatives • Evaluating Alternatives • Improving Details
