Problem solving is used by professionals from many different fields in the normal course of their work .In this chapter, we will look at the definition of design and how it fits into the overall scheme of problem solving. We will also look at the process one uses in implementing a design task. We will then discuss the computational tools are helpful to the design analysis process. Finally, we will take a brief look at where one goes to acquire technical information to augment the design process. 1-1 PROBLEM SOLVING AND DESIGN Engineering is defined by ABET the Accreditation Board for Engineering and Technology as: ---that profession in which knowledge of the mathematical and natural sciences gained by study, experience and practice is applied with judgment to develop ways to utilize ,economically, the materials and forces of nature for the benefit of mankind. What differentiates engineering from many other fields is that it attempts to go from theory into practice for the purpose of developing products and processes instead of merely observing the phenomena of that science or art. For example ,a physicist studies and records findings in order to understand better some phenomenon or physical process. On the other hand , an engineer utilizes scientific information to make a particular process or product for use by consumers. ABET further defines the design portion of engineering activity as follows: Engineering design is the process of devising a system, component ,or process to meet desired needs .It is a decision-making process often iterative,in which the basic sciences and
