An Incremental Innovation Design Process Model Based on TRIZ

Abstract

In the current market, most of the innovation is incremental innovation whose features are identifying problems based on the changing needs and solving problems without changing the current mainstream technology. An incremental innovation design process model based on TRIZ is proposed in this paper. First, with the method of product functional component tree, product without missing and redundant functions can be got through cutting the needless functions and adding the missing ones. Base on this, through constructing performance state diagram of technical subsystem, the performance which can not meet or over meet design requirements can be found. At last, construct the product’s three components -function model to transform the performances which do not meet demand into inventive problems which will be solved by the TRIZ tools. The approaches in the process model take full advantage of existing product which has known structure and performance. It avoids duplication of design and reduces design costs.
