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.
