The Technology Of Mapping Technology Maturity Of Product Based On Patent Analysis And Its Software Development

TRIZ points that all products are "technical systems" based on the core technology. The technical system evolves over time, which process parallels the micro-evolution of biological systems and illustrates the life cycle stages of child, growth, maturity and decline. What evolves is the characteristic index of the technical systems whose improvement is shown by a s-curve on the time-scale. The position of current product on its evolution calls the technology maturity of the product (TM) and the process of identifying TM calls the technology maturity mapping (TMM).To enterprises that live in a changeful market, the index of TM is an important guideline for laying a course and trading technology. It also is a crucial reference for choosing the valid proportion between systematic innovation and partial innovation, by which enterprise can hold the chance for innovation. The TM helps enterprise weigh up his level and potential of technology. So that it can make innovation considering the situation, reduce the risk and increase the profit on investment, and gain and keep an advantage of competition.Based on an analysis of process of technical system evolution, this thesis puts forward the definition of TM of product and TMM, and discusses the importance of doing TMM from multi-angles.After analyzed the existing methods of the technology maturity mapping, some defects can be detected in these methods on the aspects of data acquiring, algorithm, veracity and so on. By integrating all the existing fruit and considering the condition of our country, a new model of the technology maturity mapping that applies patent analysis is put forward. And the phases of product lifecycle divided by the new model, the resultant items for justifying the TM as well as the algorithm and approaches using these items are discussed.On the basis of requirement analysis of the software, system analysis is done by using the Fashion Method that represents the second-generation object-oriented technology, and the object model as well as the interface model is developed. The program design has been finished on the platform of VC++6.0. The software includes patents analysis and statistic, curve fit and algorithm implementation.Eventually the technology maturity of the butterfly valve is mapped by using the method put forward by this thesis and the software, and the result is discussed.
