Kansei Engineering-based Design Research On The Side Elevation Feature Line Of The Hatch-back Car

Traditional designs mainly concern about product functional features,with the development of economy and improvement of consumption level, people nowadays pay attention not only to product functional features, but also to form perception, which produces an urgent need for product form perception support technology.This paper takes the side elevation feature line of the hatch-back car as main object of study. It steps from Kansei engineering, which can convert consumers’preference into relevent design variables like products’side elevation feature lines. Therefore it can indicates designers how to design consumer-oriented products.First, we can protract the side pictres with SolidWorks software, and choose the represent one. The tasks conducted in this study include developing an appraisal scale for car product form by first framing the set of appraisal words and then purifying it according to statistic methods and experts’opinion, establishing the relationship model between consumers’preference and car product form perceptions and proving its validity, finding out the latent factors which potentially affect consumer preference. Establishing a model from consumer preference to design variables, which provide a bridge for designers.The tasks optimize the model between consumer preference and design variables with genetic algrithm,find the best solutions which are based on the semantic words and come from the primary population.The results of this paper can indicate designers how to design consumer-oriented products, and also help car product designers with technology support and other product designers with method reformation.
