Preliminary model and product design

During the course of product design the industrial designer ought to harmonize the relationships of a lot of systems between product and human being,product and environment,product and civilization,product and economic benefit etc.,then and only then could the designer be able to design a practical,economic,beautiful,safe and comfortable and green environmental new product.Along with the continuous renewal of digital technique,the young designers are more and more depending on the digital facilities to carrying out structural design and model manufacturing.In the transformation from abstractive numerals to virtual formation of product,human being is lacking the real feelings on the formation,thus there will naturally be many unreasonable places in the being designed product.Therefore while the industrial designer is at the same time enjoying the new technique of design and obtaining high efficiency of design should not ignore the fundamental mission of design and must face up to the reasonability of the traditional designing skill.It has been considered by this paper that during the designing stage of product structure,the manufacture of traditional preliminary model is not only the necessary measure for harmonizing the designer's contradictions between rationality and sensibility and between visual sense and sense of touch but also an important channel for lowering the designing cost.
