There have been 3E problems of energy, economy and environment since the earth has its history. Especially, the energy and environment problems have been getting serious after the modem industry revolution. Therefore, the demand of gas as an eco-friendly energy source is getting increased. With the demand of gas, the installation and use of gas boiler is also increased, so human life injury by the waste gas(CO) of boiler goes on increasing every year. It is the content about a life of the exhaust tube which is used at Gas boiler in this paper. We explain also the course to apply the 6SC(6 Step Creativity)of practical TRIZ and evaluate the resolution.

This paper represents a study on the development of the conceptual design for the bicycle transmission by TRIZ. At first the problem of the transmission of commercial bicycles was analyzed. The problem was defined as "the variable sprocket pitch diameter with respect to the tension change of chain". The conceptual solutions were derived by Su-Field Model Analysis, IFR(Ideal Final Result), SLP(Smart Little People), and Contradiction Matrix. The here developed sprocket prototype shows the automatic change of sprocket pitch diameter with the tension change of chain.

Recently, paradox management is a new paradigm to solve the management dilemmas. This is a new perspective and a creative way of thinking to draw the synergic effect by pursuing simultaneously the conflicting elements. As one method for the paradox management, this paper proposes a process of combining the TOC (Theory Of Constraints) and TRIZ (Russian Theory of Inventive Problem Solving) and applies to a dilemma case in business environments.

This study is to solve the public education's dilemma between the standardized education to maximize learning efficiency and the personalized education to maximize learning effectiveness, using the paradox management process. The process is based on combining the TOC (Theory Of Constraints) and TRIZ (Russian Theory of Inventive Problem Solving), which is a creative way of thinking to draw the synergic effect by pursuing simultaneously the conflicting elements. Through this research, a new concept of learning method can be suggested on a public course. Further research should be performed to develop a learning guideline based on the students' empirical study results.

This paper represents a study on the development of the conceptual design for a skateboard by TRIZ. At first the problems of a commercial skateboard was analyzed. And its development objective was defined in connection with the theory of the system improvement trend. The developed conceptual design was compared with a commercial skateboard. The skateboard riding action analysis with a motion capture equipment shows the here developed skateboard more efficient than commercial one.

Mass customization meets various needs of customers as well as produces various products and service in low cost like mass production. However, low cost and product diversity have conflicting concepts. Therefore, in order to solve this problem, we need standardization methods. In this paper, we suggest a method for determining the product platform which is a set of common parts in a product family. To achieve the method, we used the Contradiction Analysis of TRIZ (Theory of Inventive Problem Solving), Using this approach, we found a model that obtains various products within limited resources and conditions. Also, we suggest another method that increases the flexibility of our method by Design Structure Matrix.

This paper describes the Blue Ocean Strategy and Business TRIZ (Russian Theory of Inventive Problem Solving) Tactics as one method for knowledge creation and innovation. The opening new market avoiding keen competition is very popular recently and is not just prosper, but survival problem. As one new strategy for finding new market, the Blue Ocean Strategy gives the big blueprint for new market, but has no enough tools to make more concrete ideas. In this paper, we suggest using the Strategy Campus and other tools in the Blue Ocean Strategy at initial stage and then, compensating the TRIZ principles to make more concrete ideas for new market as tactics. We applied it to find the new market for conventional newspaper industry and EBS (Education Broadcast System) management innovation in Korea as case studies and got better results comparing to using only the Blue Ocean Strategy.

TRIZ, the theory of inventive problem solving, is widely used in traditional engineering fields such as mechanical, electrical, and electronic engineering and generated good results. Yet there are few examples in software field. But software field requires creative problem solving capabilities more than any other fields and we expect that we can get remarkable results by applying TRIZ in this field. In this paper, we try to break the psychological inertia that TRIZ is difficult to use in software area through development of new software, the Smart Clicker, by applying TRIZ. And we present an approach how to apply TRIZ in software field.

As the word 'creation and innovation' has been the keyword in success, there has been an increasing interest in TRIZ (Theory of inventive problem solving). So far, TRIZ has been applied to electronics and mechanics as the prime mover of product innovation. This study is to explore the applicability of TRIZ to the biotechnology sector, a future emerging technologies, especially to problem solving and innovative research and development. This study was focused on red ginseng processing. Problem causes and contradictions were identified with regard to processing-related problems, and 'the 40 principles of invention' were applied to problem solving. Steamed fresh ginseng is called 'Red ginseng'. Cracks in red ginseng cause the loss of active ingredients and also are not of merchantable quality. In the 40 principles of invention, applicable ones were finally selected through contradiction matrix and brainstorming, the tools of TRIZ. With experiments, effective methods were suggested to prevent red ginseng from cracking in a steaming process.

Recently, the fast development of communication technologies has brought a great convince for human beings' life. Lots of commercial services and transactions can be done by using mobile communication equipments such as smart phones. Consequently, smart phones have attracted lots of companies to invest them for their potential growth of market. Compared with basic feature phone, a smart phone can offer more advanced computing ability and connectivity. However, based on the responses of customers, there still are many defectives such as not friendly and smooth operation, short standby time of batteries, threat of virus infected and so on needed to be improved. Therefore, this study will propose a product innovative function development procedure into TRIZ (theory of inventive problem solving) to transform voice of customers into product design and to create novel functions, respectively. A case study of smart phones will be provided to illustrate the effectiveness of the proposed method.
