Waste machine tool remanufacturing innovative design method based on TRIZ and expandable diverging tree

Abstract

The invention discloses a waste machine tool remanufacturing innovative design method based on TRIZ and an expandable diverging tree. The waste machine tool remanufacturing innovative design method includes the steps that firstly, a formal matter-element model of a waste machine tool remanufacturing design target structure is built, by determining types of elements impeding waste machine tool innovative design, a matter-field model or a contradiction matrix is adopted to obtain innovation principles, structure innovation design is conducted on the formal matter-element model of the target structure according to the innovation principles, and then the expandable diverging tree comprising a number of candidate matter elements is formed; then, an expandable correlation function based on lateral distances and place values is introduced to represent correlation degrees between the candidate matter elements and expected matter elements, then, priority-degree values of the candidate matter elements are obtained through an expandable priority-degree evaluating method, and finally, an optimal candidate matter element is decided. By the adoption of the waste machine tool remanufacturing innovative design method based on the TRIZ and the expandable diverging tree, limits on design freedom in the structure, functions, materials and the like of an original waste machine tool can be effectively eliminated, and therefore a manufactured machine tool has higher market competitiveness and customer satisfaction.

Description

technical field [0001] The invention belongs to the field of machine tool remanufacturing, and in particular relates to an innovative design method for remanufacturing waste machine tools based on TRIZ and extension divergent trees. Background technique [0002] As the industrialization of remanufactured machine tools continues to deepen, the market and customers not only hope that the performance, cost, reliability and other technical and economical aspects of remanufactured machine tools are the same as those of new machine tools, but also expect their comprehensive performance to be improved. This requires the re-planning and design of the functional structure of waste machine tools and their waste parts. However, compared with the design of new machine tools with higher degrees of freedom, the fixedness of waste machine tools in terms of function, structure, and materials severely reduces the degree of freedom in design and greatly increases the difficulty of design.

Problems solved by technology

[0004] 1) The current remanufacturing design process of waste machine tools and waste parts lacks systematization and standardization, resulting in the ineffective transformation of remanufacturing design goals into TRIZ engineering features, resulting in low efficiency of remanufacturing design and confusion in design ideas;

[0005] 2) Due to the obstacles in the original structure, function, and materials of waste machine tools, the implementation of TRIZ innovation principles is restricted to a certain extent, resulting in low efficiency or even inability to transform TRIZ innovation principles into innovative solutions.
