Design-bites - Illustrated product design booklets by Andrew Taylor

Product description

A look at common external factors and the 'Design for X' strategies used to meet them. The guide contains sections on design for manufacture and assembly, design for maintainability, design for reliability, safety and quality standards, and product survivability (design for adverse conditions). Additional sections cover environmental impact and basic materials selection.
