Application of Technology-Effict Matrix and TRIZ In Innovative Design of Rotary Cultivator

Abstract

In the process of technological evolution of products, some functions may evolve slowly, which hinders the evolution of products as a whole. In order to compensate for the imbalance of technological evolution and find the corresponding technical shortcomings, a product design process combining technology-effect matrix with TRIZ is proposed. Through searching and screening patents related, the target patent pool is obtained and each patent is labeled. We, at the same time, summarize the technical means and effects, construct the technology-effect matrix and deduce the design objectives by extracting the technical weaknesses. Finally, the design model is obtained through using TRIZ tool to analyze the design objectives. Taking the innovative design of rotary cultivator as an example, the technology-effect matrix of rotary cultivator was constructed and a technical weakness was extracted. Based on this, the innovative design of rotary cultivator was carried out with the objective of reducing the wear of rotary cultivator blade, and thus the feasibility of the design process was verified.
