Problems solved by technology

[0006] Aiming at the following defects in the existing technology: (1) The functional lexicon in the existing innovative design of auxiliary products is too large or too small to be suitable as an external information source for auxiliary design; (2) Design products are often based on design (3) The degree of correlation between auxiliary information and the product to be designed is low, resulting in the innovation of the designed product cannot meet the actual product demand

Embodiment 1

[0080] Such as figure 1 As shown, a product innovation aided design method based on a fuzzy cognitive map disclosed in this embodiment includes the following steps:

[0081] Step 1. Construct a functional lexicon N with a scale suitable as an external information source for auxiliary design according to the requirements of actual engineering problems.

[0082] When solving practical engineering problems in the field of mechanical design, a functional lexicon N with a scale suitable as an external information source for auxiliary design should be constructed according to the actual needs of the field of mechanical design. From the perspective of the size of the functional thesaurus, the more function words contained in the functional thesaurus, the different ways designers describe the same design concept, the more ambiguity will occur; the fewer the function words contained in the functional thesaurus , the harder it is to cover all product designs. The thesaurus based on RF...

Embodiment 2

[0170] Step one, two are with embodiment 1.

[0171] Step 3: According to the function of the product to be designed, obtain function words from the function lexicon N described in step 1 as product innovation auxiliary design information. Obtain the initial input vector IPV (Initial InputVector) according to the obtained function words, and multiply it with the adjacency matrix AM obtained in step 2.4 to obtain the intermediate vector MV (Middle Vector). Transform the intermediate vector MV into the subsequent input vector IPV using a binary compression function 1 . Repeat iterations until IPV n =IPV n-1 , the IPV n As the output vector OPV (Output Vector). According to the output vector OPV, the function words corresponding to the function word in the function word library N mentioned in step 1 are obtained, and the function words corresponding to the function word library N are output.

[0172] That is to use the function words that can represent the product functions...

Abstract

The invention discloses a product innovation aided design method based on a fuzzy cognitive map, relates to product innovation aided design methods and belongs to the field of product aided design andintelligent manufacture. The invention constructs a functional word bank suitable for the external information source of the auxiliary design based on the actual engineering problem requirements, andconstructs a fuzzy cognitive map according to the influence relationship between the functional words. Finally, the functional vocabulary with high product relevance and creative information requiring to be designed is output through calculation and reasoning of fuzzy cognitive maps; The output function vocabulary is used as auxiliary information for product innovation design. The innovative auxiliary information design enables the designed product to have more functions that meet actual needs, improve the actual use performance and innovation of the designed product, and solve related engineering problems. The present invention is universal, and it is preferable to engineering problems in the field of mechanical design, and is not limited to engineering problems in the field of mechanical design.

Description

technical field [0001] The invention relates to a product innovation aided design method, in particular to a product innovation aided design method based on a fuzzy cognitive graph, belonging to the fields of product aided design and intelligent manufacturing. Background technique [0002] my country has become the largest manufacturing country, but most manufacturing companies have weak independent innovation capabilities. Therefore, China urgently needs to accelerate reforms and promote the transformation from Made in China to Created in China, and the innovative design capabilities of enterprises have increasingly become a key competitive factor for enterprises. [0003] For product design companies, innovation capability is embodied in the comprehensive ability to produce innovative design solutions. Although the experience and knowledge possessed by designers are the source of innovative design solutions, they also limit the innovative design solutions produced by desi...
