Abstract：Research purposes: Technological innovation is a substantial technological action that needs science theory guiding, as well as the protection of rules and regulations for it, such as it can be got two times doing one. The purposes in this paper are guiding technological innovation in engineering field with used innovation theory and methods by developmental country.
Research methods: Exploring a lot of documentations and information in internet, and getting into the products about company developing software, the author use methods of analyzing, generalization and summarization.
Research results: exploring a theory and method to guide the technological innovation action.
Research Conclusions: On based of inducing the cause and traditional methods of innovation the technological innovation action must be guided by scientific theory is discussed in this paper. This theory is TRIZ. The basic principle, system and applications of TRIZ are discussed in the paper. Also the latest effect in information is induced. Finally, a few of enlightenments are put forward in the paper.
