Engineering Design by George Dieter & Linda Schmidt pdf

Engineering Design – Dieter’s Engineering Design represents a major update of this classic textbook for senior design courses. As in previous editions, Engineering Design provides a broader overview of topics than most design texts and contains much more prescriptive guidance on how to carry out design. Dieter focuses on material selection as well as how to implement the design process.

Engineering Design provides the senior mechanical engineering students with a realistic understanding of the design process. It is written from the viewpoint that design is the central activity of the engineering profession, and it is more concerned with developing attitudes and approaches than in presenting design techniques and tools.

The 4th Edition of Engineering Design represents the reorganization andexpansion of the topics and the introduction of a coauthor, Dr. Linda Schmidt of theMechanical Engineering Department, University of Maryland. As in previous editions, Engineering Design is intended to provide a realistic understanding of the engineer-ing design process.

It is broader in content than most design texts, but it now containsmore prescriptive guidance on how to carry out design. The text is intended to be usedin either a junior or senior engineering course with an integrated hands-on designproject. The design process material is presented in a sequential format in Chapters 1through 9.

At the University of Maryland we use Chapters 1 through 9 with juniorstudents in a course introducing the design process. Chapters 10 through 17 presentmore intense treatment of sophisticated design content, including materials selection,design for manufacturing, and quality. The complete text is used in the senior capstonedesign course that includes a complete design project from selecting a market to creat-ing a working prototype. Students move quickly through the first nine chapters andemphasize chapters 10 through 17 for making embodiment design decisions.

The authors recognize deterrents to learning the design process. Design is acomplex process to teach in a short amount of time. Students are aware of a myr-iad of design texts and tools and become overwhelmed with the breadth of designapproaches. One challenge of the design instructor’s task is to convey to the studentthat engineering design is not a mathematical equation to be solved or optimized.Another is to provide students with a cohesive structure for the design process thatthey can use with a variety of design methods and software packages.

Toward that end, we have adopted a uniform terminology throughout and reinforced this with anew section at the end of each chapter on New Terms and Concepts. We have emphasized a cohesive eight-step engineering design process and present all material in the context of how it is applied. Regardless, we are strong in the belief that to learn design you must do design. We have found that Chapter 4, Team Behavior and Tools, is helpful to the students in this regard. Likewise, we hope that the expanded discussion of design tools like bench marking, QFD, creativity methods, functional decomposition and synthesis, and the decision process and decision tools will bene?t the students who read this book.

Many new topics have been added or expanded. These include: work break-down structure, tolerances (including GD&T), human factors design, rapid prototyping, design against wear, the role of standardization in DFMA, mistake-proo?ng,Six Sigma quality, and the make-buy decision. Finally we have introduced different approaches to the steps of design so that students appreciate the range of practice and scholarship on the topic of engineering design.The authors hope that students will consider this book to be a valuable part of their professional library. In order to enhance its usefulness for that purpose, many references to the literature have been included, as well as suggestions for useful design software and references to websites.

Many of the references have been updated, all of the websites from the third edition have been checked for currency, and many new ones have been added. In a book that covers such a wide sweep of material it has not always been possible to go into depth on every topic. Where expansion is appropriate,we have given a reference to at least one authoritative source for further study

Introduction – Engineering Design

What is design? If you search the literature for an answer to that question, you will?nd about as many definitions as there are designs. Perhaps the reason is that the process of design is such a common human experience. Webster’s dictionary says that to design is “to fashion after a plan,” but that leaves out the essential fact that to design isto create something that has never been. Certainly an engineering designer practices design by that de?nition, but so does an artist, a sculptor, a composer, a playwright, or many another creative member of our society.

Thus, although engineers are not the only people who design things, it is true that the professional practice of engineering is largely concerned with design; it is often said that design is the essence of engineering. To design is to pull together something new or to arrange existing things in a new way to satisfy a recognized need of society. An elegant word for “pulling together” is synthesis .

We shall adopt the following formal dentition of design: “Design establishes and defines solutions to and pertinent structures for problems not solved before, or new solutions to problems which have previously been solved in a different way.
