Engineering Design

About the Book

Successful engineering design requires a strong understanding of fundamental concepts in the basic sciences and engineering combined with mathematics. This text provides an introduction to the design tools used in engineering design. It focuses on the first two steps of the design process: determination of need/problem clarification and conceptualization.

In addition, an overview of materials and manufacturing methods is presented. The use of Excel has been incorporated throughout the text for performing routine calculations, leaving more time for the creative aspects of the design process. Finally, the text contains an extensive discussion of systematic concept generation using the theory of inventive problem solving, TRIZ.
