TRIZ is a theory of inventive problem solving. Recently the importance of creative capabilities is being emphasized and many successful cases using TRIZ are being introduced, therefore interest in TRIZ has been increasing. But TRIZ is not easy to learn alone compared to other creative thinking tools. Although it is effective to learn TRIZ through various cases, it is not easy for beginners to experience those many cases. Therefore, we developed a software called Do-TRIZ for TRIZ learning. Do-TRIZ provides descriptions and various examples of key concepts to make it easier for beginners to learn TRIZ. Also, the learners can add new cases continuously on Do-TRIZ. Especially, process-based problem solving modules have been implemented on Do-TRIZ, in order to make it possible to solve problems based on technical contradiction, physical contradiction, and IFR(Ideal Final Result). The learners can use the modules to solve their problems and to share the results. Also, we implemented Do-TRIZ Memo app that works with Do-TRIZ.

In mechanical design part, though many design methodologies have been developed, most of them are applicable for detailed design. Therefore, when people had to do conceptual design, they relied on their individual creativity. To improve this phenomenon, some methodologies are developed such as TRIZ and axiomatic design. In this paper, both TRIZ and axiomatic design methodologies will be reviewed. In addition, some papers which contain conceptual design case study will be also dealt with. These case studies are results of application both axiomatic design and TRIZ methodology.

Recently the government banners green growth promises as a paradigm of national development which are to reduce greenhouse gases and environmental pollution by exhaust gases from automobiles. Existing in all countries around the world by using fossil fuels to minimize environmental changes are developing a new alternative energy sources. Among the emerging alternative energy, using solar energy technology is applied across the industry, but the maintenance and repair to integrate solar cells and has been a problem occurs. To prolong the life of cells integrated on a solar cell is exposed when the non-eye, etc., when not integrated by the solar cells should not be exposed. In order to resolve these contradictions, a intellectual solar green street lighting was developed by using Q(Quick)-TRIZ.

This paper presents a study on the design of a pulling module for silicon ingot and an apparatus of manufacturing silicon single crystal ingot using the same method. The pulling module is conceptually designed by using TRIZ. Czochralski method(CZ) is representative way to manufacture single crystal ingot for wafers. The seed can be broken by high tension which is caused by large weight of a silicon ingot. The solution of this problem has been derived using 6SC(6 steps creativity)TRIZ. The pulling module is actuated by DC motor and rollers. High tension in the seed is removed by the rotate-elevate motion of rollers in the pulling module. A rubber belt is included in the rotate-elevate mechanism for increasing friction between rollers and silicon ingot.

The purpose of this study was to explore the strategies for applying TRIZ to technology education. This study was carried out through literature review on contradiction, 40 principles, 76 standard solutions, multi screen method, effects, the law of technology evolution, and ARIZ, and questionnaire survey to investigate the validity. Through this study the strategies for applying TRIZ to technology education were proposed and the validity was identified. Only the '40 Principles' was appropriate to technology education of elementary and middle school. The results of this study were as follows; In elementary school technology education, segmentation, extraction, local quality, asymmetry, consolidation, universality, counterweight, do it in reverse, mediator, self service, dispose, flexible membranes or thin films, changing the color, homogeneity, rejecting and regenerating parts, and composite materials were suitable. And in middle school technology education, segmentation, extraction, local quality, asymmetry, consolidation, universality, counterweight, prior counteraction, prior action, cushion in advance, do it in reverse, dynamicity, partial or excessive action, continuity of useful action, convert harm into benefit, mediator, self service, dispose, flexible membranes or thin films, changing the color, homogeneity, rejecting and regenerating parts, transformation of properties, phase transition, thermal expansion, and composite materials were suitable.

Purpose: SIT(Systematic Inventive Thinking) has been widely used in recent years. The validity of the five thinking tools of SIT is examined, and how to improve the inventive thinking tools is investigated. Methods: Frequency analysis on the usage of the TRIZ 40 inventive principles was used. Inventive thinking tools are derived by eliminating principles with low frequencies and grouping similar principles together. Results: Segmentation, prior action, combining, extraction, cushion in advance, transformation of properties are most frequently used among the 40 principles of TRIZ. The most frequently used principles and similar principles with them are grouped into new inventive thinking tools. Two of them, division and attribute dependency, belong to the 5 thinking tools of SIT, and the others, proactive measures, combination and reversal, do not. Conclusion: The newly identified inventive thinking tools are division, combination, proactive measures, attribute dependency, and reversal. The new five inventive thinking tools are quite efficient since they can cover more than two thirds of the TRIZ 40 inventive principles.

Global warming is affecting all industries, and has been applied very quickly in the energy sector. Existing in all countries around the world by using fossil fuels to minimize environmental changes are developing a new alternative energy sources. Among the emerging alternative energy, using solar energy technology is applied across the industry, but the maintenance and repair to integrate solar cells and has been a problem occurs. To prolong the life of cells integrated on a solar cell is exposed when the non-eye, etc., when not integrated by the solar cells should not be exposed. In order to resolve these contradictions, a square solar flower of the biological mother was developed by using TRIZ technique(6SC).

Although companies have to concentrate on effort to save cost to survive competition, transportation costs are taking more portions in total sales costs due to globalization in the modern times. It is the reason why Transportation Management System TMS is getting more important. However, it is practically difficult for the system to fit to all of transportation environments and actually many problems are taking place with the system. Therefore, a new idea is necessary to solve such problems fundamentally rather than temporarily or superficially. To do so, if TRIZ, which is a theory that systematically establishes creative ideas on the basis of patent analysis, is employed, it can bring forth a guideline with some creative principles that can be applicable in drawing out innovative ideas based on conceptual shift. The present study aims to propose a methodology of how TRIZ should be applied to solve the problems that happen in TMS as a whole. Particularly, the study focuses on how to design customized TMS system that can be employed for each of different situations in a creative way.
