[edit] Abstract
This paper presents a method for evaluating the lightweightedness of a vehicle, specifically addressing those components whose primary purpose is to aid in manufacturing and assembly rather than to provide end-user function. Seven specific laziness indicators are described and illustrated: rigid-to-rigid connection, support for a flexible, non-moving part, positioning feature, duplicate geometry, fastener, bridging system, and material flow restriction. These indicators are used to evaluate individual vehicle components as part of a proposed method for identifying mass reduction potential. The indicators do not require extensive knowledge of the functionality of the components being evaluated. The purpose of the proposed method is to focus the attention of designers on components or assemblies with high potential for mass reduction.
