Fundamentals of Engineering – Honors – ENGR H191 Lecture 23 – Design Process1 The Design Process Overview of the process Design versus other aspects of engineering Steps in the design process Communication skills References: BTG, Chapter 14 “The Engineering Design Process, 2 nd Edition” by Atila Ertas and Jesse Jones, Wiley, 1996.

Fundamentals of Engineering – Honors – ENGR H191 Lecture 23 – Design Process2 “Design is the most creative part of the total engineering process.” An engineer will typically engage in various activities in their career. They may include Research Development Testing Manufacturing The Design Process  Technical Service  Construction  Sales  Management  Design

Fundamentals of Engineering – Honors – ENGR H191 Lecture 23 – Design Process3 Engineering Design Engineering design sometimes is the creation of an original product typically is the refinement or modification of an existing product Pie chart Page 664 REF: Technical Graphics,p664

Fundamentals of Engineering – Honors – ENGR H191 Lecture 23 – Design Process4 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!!!

Fundamentals of Engineering – Honors – ENGR H191 Lecture 23 – Design Process5 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.

Fundamentals of Engineering – Honors – ENGR H191 Lecture 23 – Design Process6 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.

Fundamentals of Engineering – Honors – ENGR H191 Lecture 23 – Design Process7 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

Fundamentals of Engineering – Honors – ENGR H191 Lecture 23 – Design Process8 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

Fundamentals of Engineering – Honors – ENGR H191 Lecture 23 – Design Process9 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
