Embodiment

[0030] Taking the MP3 music player as an example, the hierarchical user tacit knowledge expression method includes the following steps:

[0031] 1) In the visual product design scheme, take MP3 music player design as an example, such as figure 1 As shown, 24 samples are collected, and the design features of MP3 music players are divided into two levels, that is, the product as a whole and components, such as figure 2 shown;

[0032] 2) the design components and candidate scheme definitions of the MP3 music player are as shown in table 1,

[0033] Table 1 Product Design Factors of MP3 Music Players

[0034]

[0035] The overall design semantics are contained in the perceptual cognition of each component, such as the body, screen, function keys, and decorative lines, etc., and the perceptual cognition of components is reflected in the implicit utility of the candidate shape. To express the implicit knowledge of product design semantics , define the product as follows

Abstract

The present invention discloses a semantic evaluation method based on the layered product design. A graphical method is used for visualizing the product design, dividing the product design into layers, and transforming implicit knowledge. In the visualized product design, the orthogonal design and the full-profile method are used for semantic evaluation of the product design; the regression analysis is used for calculating the importance of the product components in the semantic evaluation of the whole design; the degree of recessive utilization of each candidate shape of the product design is then evaluated, to acquire the semantic evaluation of the ultimate product design. The semantic evaluation method effectively realizes the expression of the implicit knowledge in the process of the product design, compensates the quantitative research on the graphical method, and improves the semantic research efficiency of the product design.

Description

technical field [0001] The invention relates to a method for extracting and expressing product design semantics, in particular to a method for evaluating product design semantics based on layering. Background technique [0002] Design is to use existing knowledge, skills and technology to solve problems or create new things, and it is an important creative activity of human beings. However, those existing knowledge and skills are often implicit, and it is difficult for even skilled designers to clearly say what knowledge, skills and how they use them in design. This tacit knowledge includes those informal and hard-to-express skills, techniques and know-how, etc., which are the result of long-term accumulation and creation of individuals. This kind of knowledge has subjectivity, randomness and ambiguity. To conceptualize this kind of knowledge is the difficulty and key of knowledge modeling, and it is also the basis and source of knowledge management and design innovation. ...
