The document discusses engineering design and the engineering design process. It defines design as creating something new by arranging existing things in a new way to satisfy a societal need. Good design requires both analysis of how a part will perform and synthesis to identify design elements. The engineering design process starts by determining a need, gathering information, stimulating design concepts, investigating concepts using analytical tools, reviewing information, testing the best design, and optimizing through iteration. Types of design discussed include original, adaptive, redesign, selection, and industrial design.

2. What is Design? “to fashion after a plan” - Webster's dictionary to design is to create something that has never been although engineers are not the only people who design things To design is to pull together / synthesissomething new or to arrange existing things in a new way to satisfy a recognized need of society

3. Design Good design requires both analysis and synthesis Understand how the part will perform in service Able to calculateexpected behavior before it exists in physical form by using the appropriate disciplines of science and engineering and the necessary computational tools – ANALYSIS Identification of the design elements that will comprise the product into workable system -SYNTHESIS

5. Engineering 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!!!

6. Engineering Design Process contn’ 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.

7. Engineering Design Process contn’ 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.

8. Engineering Design Process contn’ 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

9. Types of Design Original design - innovative design, It employs an original, innovative concept to achieve a need Adaptive design - adapts a known ' solution to satisfy a different need to produce a novel application Redesign - improve an existing design

10. Types of Design Selection design - design task consists of selecting the components with the needed performance, quality, and cost from the catalogs of potential vendors Industrial design - improving the appeal of a product to the human senses, especially its visual appeal, more artistic than engineering
