A Method of Controlling Design by Criterion

Abstract

A method of controlling design by standards, the method includes a basic standard data collection step, which is used to collect and organize the drawings of the products of the enterprise and the components used in the products and the corresponding standard information through the standard management equipment, The standard data management step is used to manage the affected products in the life cycle of the enterprise's standard generation, change, replacement, replacement, and extinction, and the design data management step is used for the design department of the enterprise to In the design stage of the production drawing of the equipment, the designer will be prompted according to the data changes in the standard data management steps. The invention proposes a standard-based control design method, which manages standard data with components as units, and can ensure the implementation of the standard from the design stage.

Description

technical field [0001] The invention relates to a method for managing the design process in the part drawing design stage before product production, especially a method for design management using standard data that product parts need to follow. Background technique [0002] In the "Standardization Law of the People's Republic of China", it is stipulated that standards should be formulated for the following aspects related to industrial products, [0003] 1. The variety, specification, quality, grade or safety and sanitation requirements of industrial products. [0004] 2. The design, production, inspection, packaging, storage, transportation and use methods of industrial products or the safety and hygiene requirements in the process of production, storage and transportation. [0005] 3. Technical terms, symbols, codes and drawing methods related to industrial production, engineering construction and environmental protection. [0006] For industrial products, especially fo...

Problems solved by technology

[0010] 3. Are the enterprise standards being used still citing the abolished standards? Will the product design still mistakenly adopt the abolished standards and the standards that need to be revised?

[0012] If these problems are not resolved, it will inevitably lead to a reduction in the qualified rate of the product, a waste of materials and processing resources, and in severe cases, it will also bring safety hazards to consumers of the product.

[0013] For example, for an enterprise that produces aircraft engines, each of its aircraft engine products consists of thousands of components, and each component should comply with the corresponding national or military standards or aviation or enterprise standards. , the enterprise standard may refer to the national standard or navigation mark of the upper level. For example, if a bolt should comply with the corresponding enterprise standard, when the content of the national standard quoted by the enterprise standard has been partially changed, the material or processing technology of the bolt should When the change is made, if the enterprise standard cannot be updated in time, or the updated enterprise standard cannot be fed back to the first-line production department through the design department to update the production drawings in time, the production department will still carry out bolt production according to the enterprise standard before the change on the old drawings , In this case, the produced bolts cannot meet the acceptance requirements, thereby wasting materials and processing resources. If these bolts are accidentally assembled on the aircraft engine and circulated to customers, it may also bring serious safety hazards

[0014] The existing standardization management work mainly relies on manpower and paper-based management. Since a single product may involve thousands of standards, on the one hand, pure manual management is inefficient and cannot effectively solve the above problems. It is easy to find out which parts and components a certain standard is used in. In addition, it is easy to cause errors and omissions in standard management information, and it is easy to use (or quote) outdated obsolete standards in enterprise design and production. Outdated standards for design and production, resulting in an increase in the rate of unqualified products, or making the company's products unable to meet customer requirements

[0015] Chinese patent CN101436200A provides a standardized information management system and its standard update method. This patent provides a method that can automatically update the data information of the standard adopted by the enterprise and send the updated information to the corresponding user. However, for the standard in the design , production and other processes have been implemented and did not provide a corresponding solution
