[edit] Abstract
One approach to lightweight vehicle design, presented in previous research, is through the identification of “Lazy Parts”. In this paper, the lazy part identification procedure is applied to an interior automotive console consisting of eighty-eight parts. The evaluation identifies lazy aspects of parts and estimates mass savings potential based on the elimination of the parts’ laziness. This analysis demonstrates a mass savings potential of the console of approximately 2 kilograms, or 14% of the total mass of the console. The frequency of use of seven Laziness indicators and various combinations of these indicators is also analyzed, and it is determined that the greatest potential for mass savings within the console occurs when a part has rigid-to-rigid connection and duplicate geometry indicators. This analysis also demonstrates that novice designers can analyze a system based on geometric and assembly relationships, with a limited understanding of functionality, to identify potential mass savings.
