  1. The Design Process Lecture 23 Autumn Quarter

  2. The Design Process • Overview of the process • Design versus other aspects of engineering • Steps in the design process • Communication skills References: BTG, Chapter 14 Section 1.2.2, Tools and Tactics of Design, Dominick, et al, Wiley, 2001 Autumn Quarter

  3. “Design is the most creative part of the total engineering process.” Engineers will typically engage in a variety of activities in their careers. They may include: Research Development Testing Manufacturing Technical Service Construction Sales Management Design The Design Process Autumn Quarter

  4. Engineering Design • Engineering design • sometimes is the creation of an original product • typically is the refinement or modification of an existing product REF: Technical Graphics,p664 Autumn Quarter

  5. The Design Process • Starts with recognition of the need for the product. • Both design and redesign require knowledge of the intended use of the product, plus information on the • Market • Technical data • Materials and production • For any product design you are part of a team ! Autumn Quarter

  6. The steps in the design process. • Determine the need • Starts with recognition of a need • Sketching of the solution (product) is very useful during this step. • Establish Known Information • Includes gathering information on aspects of the products such as possible materials, market analysis, ability to manufacture, cost to manufacture, etc. Autumn Quarter

  7. The steps (continued) • Stimulate Design Concepts • Consider the various aspects in the manufacture of the product such as material, shape, etc. • Investigate Design Concepts with Analytical Tools • Use modern methods and tools to analyze design alternatives. Autumn Quarter

  8. The steps (continued) • Gather all information and review • Gather together all information and design alternatives and review so that decisions can be made. • Test the design that appears best. • Accept, Modify, or Reject • Optimize the design by iteration Autumn Quarter

  9. Design in the today environment • Engineering design has undergone significant change when compared to 20 years ago. • Teamwork is paramount in the modern workplace. • Computer applications for analysis of a design are essential. • Other major concerns in the modern design process • Safety and environmental protection • Product reliability • Engineering Ethics Autumn Quarter

  10. Technical communications • As engineers work as a part of a team, communication skills are very important • In the engineering field, one is rarely judged on the quality of ones technical work alone. The ability to communicate your ideas and what you have done is crucial. • Good communication skills (both oral and written) take practice • This include skills such as writing, sketching, using CAD tools, etc. • Giving presentations Autumn Quarter
