Example Embodiment

[0040] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0041] The principle of the present invention is:

[0042] The existing product design data contains certain design principles and design rules, and the existing products have certain novelty. Therefore, using data mining and statistical learning methods, an evaluation model can be constructed from existing products to support the evaluation of product concepts, which helps to gradually get rid of the qualitative expert evaluation method based on personal experience. The function of a product represents customer needs, is the starting point of product design and development, and is also the basic criterion for testing product design results. The component that realizes the function is an important aspect that reflects the performance of the product, is an important aspect that meets the needs of customers, and is directly related to all aspects of the ...

Abstract

The invention discloses a product concept novelty evaluation method based on a knowledge base. The method can directly calculate a product concept novelty value according to a product concept, and canprevent uncertainty brought by expert evaluation. The method comprises the following steps: extracting product concepts from existing products and converting the product concepts into a data expression form, and storing the product concepts into a product concept knowledge base; analyzing the product concept knowledge base using a mathematical statistics method, and determining key characteristicparameters of each product concept; determining novelty indexes as evaluation standard, obtaining a value and weight of each novelty index by an expert evaluation method, determining a novelty valueof a product concept; using the key characteristic parameters of product concept as input of an artificial neural network and the novelty value of the product concept as output of the artificial neural network, training the artificial neural network, to obtain an evaluation model of product concept novelty which is used to evaluate novelty of a product concept to be evaluated.

Description

technical field [0001] The invention relates to the technical field of product concept design, in particular to a method for evaluating the novelty of a product concept based on a knowledge base. Background technique [0002] In the fierce market competition environment, new product research and development capabilities are an important source for enterprises to maintain competitiveness. In the process of product development, conceptual design is the most important, critical and most innovative link. Its main task is to complete the generation and evaluation of product concept proposals. The evaluation of conceptual proposals is the process of scoring the generated series of conceptual proposals under different evaluation indicators, and then selecting the most conceptual proposals. Since conceptual design is in the early stages of product development, the quality of the conceptual scheme will have a great impact on the subsequent stages of product development. Studies ha...
