Description

Product design system and design method thereof Technical Field The invention relates to the technical field of information, in particular to a product design system. Background In the design and production management of industry standard products, a manual design mode is generally adopted at present aiming at personalized orders of customers. Taking a valve as an example, engineers need to manually search part manuals according to customer demands (such as nominal diameter DN, nominal pressure PN, materials and driving modes), perform product model selection, modeling, assembly drawing in a CAD or PLM system, and finally compile a bill of materials (BOM). This process has the following significant problems: (1) The efficiency is low, the repeatability is heavy, the order technology preparation period is long, the market is difficult to quickly respond, and large-scale customization cannot be realized. (2) The accuracy is poor, the personal experience of engineers is highly relied on, and problems of inconsistent design parameters and requirements, material selection errors (such as mismatching of pressure levels and incompatible interfaces) and the like are easy to occur, so that the design reworking or hidden danger of product quality is caused. (3) The knowledge inheritance is difficult, namely the design experience (such as type selection rules and check logics) of the senior engineers is mostly implicit knowledge, the settlement and the multiplexing are difficult, and the flow of personnel can lead to the loss of knowledge. (4) The standardization is insufficient, design output varies from person to person, resulting in a lot of product variants, which is unfavorable for supply chain management and production cost control. Some existing product configurators (or called product design software) mainly focus on the selection and quotation of the front end of sales, the output result is only a preliminary material list, and no deep engineering rule verification exists, so that accurate design data (such as production-level BOM, processing drawing and the like) which can be used for guiding production cannot be automatically generated, namely, the design of the product still needs a great amount of secondary design and verification work of designers. Disclosure of Invention In view of the fact that the existing product design software has low design depth on the product, can not automatically design a first draft which can meet the needs of technicians, can not finish the manufacturing patterns for production, a product design system and a design method thereof are necessary, and the problems of low efficiency, easiness in error and difficulty in standardization caused by the fact that the technicians design single products or small batches of products are adopted are solved.

The invention realizes the automatic design of the technology and the process pattern of the product to be manufactured, reduces the workload of technicians, and also realizes the standardized design of the product. Furthermore, the user interaction module adopts a Web configurator to provide a market demand information input interface, a user directly fills in required information or parameters in the corresponding bar window, and the user interaction module directly stores and records the information or parameters input by the user, so that the input and storage synchronization is realized.
