Abstract

The importance and foundation for attachment-level design of integral snap-fit assemblies was first pointed out by Bonenberger at General Motors [1–3]. Based on that work, a method was developed and tested and is presented here to identify and address important issues at the conceptual stage in a systematic way and generate alternative attachment concepts. The method starts by exploring the design space to generate as many concepts as possible [4]. Alternative concepts are generated by considering variations in attachment interface geometry, assembly procedures, actual snap-fit features, and options for fully constraining all parts of the assembly using locators beyond locks. In the last step, alternatives are evaluated using a quantitative tool, and a “best” attachment concept is selected based on design objectives for a particular application. Applying the method to case studies has confirmed that it is a useful design aid for efficiently generating, and evaluating, or simply checking attachment concepts. [S1050-0472(00)01003-5]
