Embodiment 1

[0035] Knowledge exists in various forms, such as design examples, which include design models and associated design documents, which are the final design solutions for finalized products; design examples include information such as technical information, experience skills, calculation formulas, and design parameters. , Technical information is a variety of literature reports in discrete form, including standard specifications, technical manuals, research reports, patents, academic papers, etc. Experience skills are solutions to specific problems accumulated by designers in long-term practice. This kind of knowledge mainly exists in the form of tacit, which needs to be fully excavated to make it explicit; calculation formulas and calculation parameters are mainly for Validated empirical formulas and parameters for specific design problems. Due to the lack of systematic organization in the prior art, these knowledge resources generally exist in a discrete form and cannot form a...

Embodiment 2

[0051] The knowledge unit described in Embodiment 1 is a static knowledge resource organized for a certain design activity. It has certain pertinence and the scope of knowledge that can be queried by each knowledge unit is small. Therefore, if only knowledge units are used to assist design, then When designing a product, it is necessary to manually analyze the specific solution to the problem, and then combine the solution with the solver used by the corresponding active node to solve the problem. In fact, there are a large number of modeling and analysis problems in the product design process, such as parameter solving, structural analysis, fluid analysis, thermal analysis, etc., these solving or analysis processes are carried out with the support of certain empirical formulas or professional software Yes, in order to obtain accurate solution results, designers are required to be proficient in professional knowledge, have rich practical experience, and be able to master the us...

Embodiment 3

[0073] Knowledge units and knowledge components can only be used within the project team. If they want to expand their scope of use (knowledge sharing between project partners), they need to be further transformed into knowledge services. Therefore, on the basis of the second embodiment, this embodiment forms knowledge components into knowledge services that can be used by other users, and provides a product design knowledge management method based on knowledge services, such as Figure 6 As shown, the method includes the steps of:

[0074] S1: According to the knowledge needs of each design activity in the historical product design process, collect and organize the knowledge resources related to each design activity and combine them into knowledge units corresponding to each design activity. For the specific implementation of this step, refer to Embodiment 1, which will not be repeated here.

[0075] S2: Analyze the design steps and required solvers of each design activity, ...

Abstract

The invention provides a product design knowledge management method and a product design knowledge management system, and relates to the field of computers. The method comprises the following steps of: collecting and organizing design cases related to each design activity according to the knowledge requirements of each design activity in a product design process, and combining the design cases into knowledge units corresponding to the design activities. Or, after the formation of the knowledge units, the method also comprises the following steps of: analyzing design steps of each design activity and a required solver, and packaging the knowledge unit, the design steps and the solver, which correspond to each design activity, into a knowledge component corresponding to the design activity. After being formed, the knowledge components also can be registered and published to form shared knowledge service. The product design knowledge management scheme has the advantages of integration, knowledgeability, parameterization, automation, configurability, navigability and the like, complexity in problem solving is lowered, and requirements for the design experiences of a designer are lowered.

Description

technical field [0001] The invention relates to the field of computers, in particular to a product design knowledge management method and system. Background technique [0002] At present, complex products with high, precise and cutting-edge technical features require high performance indicators, complex structures and working conditions, high system integration, and involve multiple disciplines and specialties. Therefore, the product design process of such products is a technology-intensive and knowledge-intensive process. Intensive and highly complex creative activities require extensive sharing of knowledge resources within and between enterprises. At present, due to the lack of effective methods and tools for summarizing and sorting out product design-related knowledge, enterprise design knowledge is independent and scattered, complicated and disorderly, and the reusability rate is not high. Designers need to spend a lot of time searching for relevant knowledge before sta...
