It could have been about 1/5th the length and still contained the same amount of information. He spends a lot of time on definitions instead of practical information. After purchasing his book, I found some free snap-fit design guides on the internet that I found much more useful. Rating: 2 / 5 I agree with the other people who said this book repeats itself.

Bonenberger Sun, 28 Mar 2010 13:28:38 +0000 http://www.petroscrap.com/the-first-snap-fit-handbook-creating-attachments-for-plastics-parts#comment-478 Potential readers should take advantage of this site's feature that lets you review this book's Table of Contents and Introduction. As is clearly explained in the "Introduction" and "Reader Expectations" Sections, this book is not just about equations for snap feature behavior. There are indeed many sources for feature behavior calculations; some are provided in the book. This book is useful if you want to understand a snap-fit attachment as a system in order to avoid many common errors. Many of these errors are trivial, but they are repeated again and again in all kinds of plastic products. My personal experience is that the root causes of most snap-fit attachment problems are neither prevented nor resolved by simply calculating feature behavior and a 'systems' approach is essential. To post this message, I must rate my own book; this is not an attempt to bias the ratings.

This is an excellent resource book for design, and a helpful resource when putting together snap-fit design workshops for jr and sr mechanical engineers.

It will avoid the mistakes a young engineer might make, and the writer also provides several very good examples to guide experienced engineers' creativity.

It discusses snap fit mechanisms, locators, locating schemes and overconstraints, design-for-assembly, and the snap-fit function from the end user point-of-view. It includes formula for calculating all of the important functions I wanted to predict in a design. It goes through a logical design sequence to create a snap-fit design that works in your particular application and identifies what you should and should NOT do. Some things were trivial for plastic design, others were not obvious and had not occurred to the design teams in which I have participated.<p>After reading this book I immediately recognized poor snap-fit designs on products I have worked with for years. A mechanical analysis of an optimized snap-fit based on this book showed how these concepts would have helped tremendously in the initial product design phase. I will certainly use this book in all my future snap-fit designs. Rating: 5 / 5 This book is a very good reference for designing plastic snap-fit features.
