Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] The maintainability qualitative design method in the product design stage of the embodiment of the present invention is realized based on the obstacle tree and the modified maintainability conflict matrix based on TRIZ, and the implementation steps are as follows:

[0021] step one:

[0022] Establish maintainability design obstacle tree for design target;

[0023] The maintainable design obstacle tree is a logical tree diagram of the maintenance design obstacle occurrence process represented by a Boolean relationship from the result to the cause, and the basic structure is as follows figure 1 As shown in Fig. 1, the maintainability design obstacle tree graphically represents...

Abstract

The invention discloses a product design stage maintainability qualitative design method. The method comprises the following steps: establishing a maintainability design obstacle tree for a design target; performing qualitative analysis on the established maintainability design obstacle tree, and analyzing a minimum cut set and a minimum path set of the maintainability design obstacle tree to obtain a conflict vector of the design target; obtaining a corrected maintainability conflict matrix according to a TRIZ conflict matrix, determining a deterioration parameter and an improvement parameter of a maintainability design conflict matrix, and establishing a mapping relation between an invention principle set and a product design feature set. According to the method, a TRIZ original understanding vector is obtained by adopting a correction maintainability conflict matrix based on TRIZ, a relation matrix of a design conflict vector and an original understanding vector is obtained by combining the obtained conflict vector, and a conflict vector-original understanding vector relation equation of a corresponding conflict design system is established to help design decision making. The invention provides a method for solving the conflict problem between maintainability design requirements and other quality design characteristics.

Description

technical field [0001] The invention relates to the technical field of maintainability design, in particular to a maintainability qualitative design method in the product design stage, in particular to a maintainability qualitative design method in the product design stage based on obstacle tree and maintainability conflict matrix based on TRIZ theory. Background technique [0002] Design quality is very important to products, and obtaining high-quality products with the least cost has become the main pursuit of product design today. The formation of product design quality is not only in the manufacturing stage, but also in the design stage and after-sales service stage, especially the design stage plays a decisive role. Maintainability is a quality characteristic of the product itself and must be injected into product design. Incorporating maintainability requirements into the product design process and realizing maintainability requirements through design and verification...
