Exploration On Cognition Of Product Formal Based On Semiology And Aesthetic

In today's highly competitive marketplace, how to meet consumers' needs in a shorter lead time is very important for an enterprise. So the strategy of developing a product is transformed from product-push type to market-pull model. A well-designed product should not only satisfy consumers' physical requirements but should also satisfy their psychological needs. Customers generally expect to perceive some critical images from the product. However, do designers really know what product images consumers want? Even if they know what images to express, do the users perceive the same expected images the designers have aimed to express in products? The psychological problem focused on the image perceptions for a product is full of fuzziness and uncertainties. Traditionally, this problem is solved by the designer's experience, habit, intuitive feeling and inspiration. This design model is lack of theoretical support. It is difficult to create the form for the product thereby expressing the specific characteristic and image of the product which fit consumers' favorite. Recently systematic and scientific research on product image or product style, such as Kansei engineering and fuzzy theory, is developed.This thesis firstly explains the new tendency of product design in the 21st century. Then it presents the current achievements and trends of Semiotics and Kansei engineering. Afterwards, it probes into existing written words as to the cognition and rebuilding of style and points out their problems. In this way, a new design methodology and procedure is necessitated. In the style and image chapter, expatiating on the means of image and style. In the two levels of the style, sense attributes are introduced respectively, namely the form of a sign, the structure of a sign and the meaning of a sign. As is known to all, people's understanding of the integrity of a product (style) is greatly impacted by the form and structure of a sign. Therefore, this thesis explains in detail the form of a sign and its corresponding meanings as well as different rules embedded in the structure of a sign. These rules dictate products' combinations and structural relationships in the stylistic design system and indirectly affect the expressiveness of style and its degree. We set up the stylistic cognition on the basis of the aesthetic, which is of significance to both the selection of typical mobiles into the database for stylistic mobiles and to the filtration of common feature sets. A case study of mobile based on signs and aesthetic is conducted to instantiate and verify those theories mentioned in the former chapters. At the end of this chapter a tentative computer-aided prototype system for stylistic design is elicited. Yet it is supposed to work when designing simpleproducts. I hope that my study will help to shift the practice experience to some feasible theory.
