Research On The Innovative Design Of Electro-haulage Shearer

Concept design serves as the most creative stage in the process of product design. Innovation is the feature of concept design. It plays a decisive role in product design. TRIZ is theories of inventing problems and solving issues. The theory of TRIZ can provide an effective theoretical support in the process of conceptual design. We can predict the direction of product development and obtain the design direction of product concept by the study of product technology of evolutionary trends. We can clear and definite the product problems should be solved by researching idealization principle and conflict. We can inventively solve the problems by studying conflict solving theories. This paper discusses the definition of the conceptual design, characteristics, content and developing situation, studies the methods and processes of the conceptual design,as well as the theory supported by TRIZ theory when it is in the procession of conceptual design.Meanwhile, the thesis also discussed TRIZ theory in detail.Electro-haulage shearer, which undertakes the main function of cutting coal,is the equipment used for exploiting coal mine. Its reliability directly affects the production of the coal.Thus, it is imperative to improve its performance, function and reliability. This paper studies the Electro-haulage shearer's developing status, structural features and technical status at home and abroad. And it puts forward the designing and innovating point about the electro-haulage shearer.This paper, by studying conceptual design method about product and TRIZ theory, brings forward process and method of conceptual design based on TRIZ theory, which combines with the developing status and technical features of electro-haulage shearer.At the same time, they were used in the conceptual design process of electro-haulage shearer. The paper also analyses the Functional requirement, functional structure, evolutional tendency and idealized design, determines the concept of the coal machine, and designs the concept in detail.By using TRIZ theory this paper analyses the conflict existing in the coal machine, and improves the design through the theory of conflict resolution of TRIZ theory. At last, the paper draws the new design. Evaluating the conceptual designing scheme by adopting the fuzzy comprehensive evaluation method has bigger advantage than the former innovative scheme.Practice proves this method provides an effective way for the innovative and conceptual scheme of the electro-haulage shearer. It also can be helpful to improve the idealistic level of the electro-haulage shearer.
