Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0025] Such as figure 1 As shown, a method for constructing a product appearance knowledge base first proposes a model of the product appearance design method, and uses the model to determine the relationship between product appearance design requirements and related design information. The specific steps are as follows:

[0026] Step 1, product appearance design data collection and arrangement:

[0027] Collect a class of perceptual image adjectives for product appearance and related product case pictures from professional websites. The standard for the pictures is a color picture that can show the information of the overall appearance of the product. The collected pictures are numbered and ma...

Abstract

The invention discloses a product appearance knowledge base construction method, which comprises the following steps: collecting and analyzing perceptual intention contours and related product cases of product appearances according to a semantic difference method in perceptual engineering, scoring the perceptual intention contours of products, and extracting representative perceptual intention vocabularies as expected functions through a factor analysis method; clustering and analyzing appearance characteristics of related products as expected structures according to corresponding sample casescores in the public factors; and based on the score condition of the CMF variable element of the case product in the public factor, mapping a relationship between an expected function and an expectedstructure, and constructing a knowledge base system of the product. The product appearance knowledge base construction method has the advantages of improving the design efficiency, guiding the product appearance design, and showing the superiority of the design method.

Description

technical field [0001] The invention relates to a method for constructing a product appearance knowledge base, belonging to the technical field of industrial design. Background technique [0002] In the process of product appearance design at the present stage, the content of user needs is uncertain, and different users have very different product needs, resulting in ambiguity in demand, because people have differences in subjective cognition of fuzzy things, and There is no universal standard. In the process of investigating user needs, it is difficult for designers to extract accurate design requirements, unable to locate the expression of products and functions, which increases the difficulty of design and even leads to wrong design directions. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a method for constructing a product appearance knowledge base. [0004] In o...
