SIT(Systematic Inventive Thinking), a simplified version of TRIZ, has gained in popularity and used worldwide over recent years. In this paper, the relationship between 5 thinking tools of SIT and 40 inventive principles of TRIZ was examined. For the purpose, many practical TRIZ cases applied in a world-class consumer electronics company were analyzed. The analysis showed that SIT thinking tools were composed of 11 principles in 40 TRIZ inventive principles. Among SIT 5 thinking tools, division and attribute dependency were most frequently used. However, heavily used inventive principles such as preliminary action and beforehand cushioning were not included in SIT. If these principles are additionally reflected in SIT, the effectiveness of the thinking tools will be significantly increased.

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.

The need for integrating the arts and literature into the engineering education has been emphasized to cultivate the creative talent in recent years. However, there have been few studies to investigate how the arts and literature can be linked with nurturing creative talent in the engineering fields. In this paper, it is examined that inventive thinking principles for creative ideation in the engineering fields can be applied to the arts and literature. For the purpose, creative works in the arts and literature, which can be explained by the five thinking tools of SIT(Systematic Inventive Thinking), are collected. The result shows that engineering and the arts share common thinking patterns.

The purpose of this study is to introduce a modified CPS(Creativity Problem Solving) procedure as a new method for comparative analysis of creative techniques such as SIT(Systematic Inventive Thinking) and Brainstorming(BS) techniques. For this, a new sports game is employed as a case study. The results show that the ideas from SIT are more creative in terms of originality and practicality than those of BS. Several considerations for effective practical use of the proposed method are discussed in this study.

Purpose: This study aims to investigate the effect of product creativity on the financial performance of new product in the food industry. In addition, the applicability of creative thinking method for the development of creative new food product is examined. Methods: In this study, OPA(Originality-Practicality Analysis) method is applied to evaluate the creativity of 32 new food products of 'H' food company in Korea. Effects of product creativity on the financial performance are analyzed using t-test and logistic regression analysis. In order to examine the applicability of SIT(Systematic Inventive Thinking) for the new product development process, each subject are classified according to five SIT tools. Results: The product group belongs to creative area(CA) shows the highest financial performance among the quadrants of OPA matrix. The products are divided into two groups whether the product can be classified by SIT tools or not. The products belonged to SIT group show higher creativity than non-SIT group. Conclusion: From the result, it can be concluded that product creativity has effect on the financial performance of the new food products, and SIT can be used as a powerful tool in developing creative new food products.

TRIZ is one of the most famous tools for creative problem solving. However, it is said that TRIZ is complicated and difficult to understand and apply to solve problems. In order to resolve these difficulties, this paper presents S-ARIZ, a simplified ARIZ(the algorithm for inventive problem solving). S-ARIZ revised ARIZ-85C on two ways. First, cause and effect analysis is used to define core technical contradictions and control parameters for the physical contradictions. Second, we add 5 inventive principles which revised SIT(systematic inventive thinking) partially to IFR-1 definition (Step 3-2 of ARIZ-85C) to solve the intensified technical contradictions systematically and effectively. It is expect that S-ARIZ can contribute to the rapid spread of TRIZ.

Purpose: It can be said that the 21st century is the age of creativity. However creativity has been relatively less considered in comparison with control and continuous improvement in quality management. How to incorporate creativity into quality management is treated in this paper. Methods: The opposing characteristics of quality and creativity are examined, and the possible outcomes resulted from the conflict are reviewed. Previous researches on managing evolutionary and revolutionary changes are also examined. Results: Quality and creativity require each other although they have incompatible characteristics, and can be incorporated into the innovation cycle. Conclusion: Creative thinking tools such as SIT should be included in the quality training and education for the effective operation of the innovation cycle.

In this research, Many people understand that the (accidental) tip and the "analogy" that leads to it have played a central role in many instances of creative problem solving.And it has been pursued as a way to get more hints to make a 'knowledge base' which is a collection of many cases. The Unified Systematic Inventive Thinking (USIT), which makes it easier to apply TRIZ, will seek out various ideas through a process of analyzing the current system and examining the ideal system more clearly. In this paper, we describe the rationale and application procedure of the "6 step thinking method" which improves the "4 step thinking method".

It is examined that how flipped learning and mind-wandering affect an idea generation task. For the purpose, the participants in the idea generation task are divided into two groups to learn SIT(Systematic Inventive Thinking) and BCC(Business Creativity Codes) as idea generating tools in advance. One group learned the tools in a classroom, and the other group through an online education program. The creativity level of an idea is evaluated in the dimensions of originality, practicality, and realizability. The creativity levels of the ideas from the two groups are not statistically different in all the three creativity dimensions. To examine the effect of mind-wandering, another group generated ideas two hours a day in four days instead of eight hours in one day. The creativity levels of the ideas from the third group are higher in the dimensions of originality and practicality. This shows that the effectiveness of flipped learning is not so different from the face-to-face learning in a classroom, and mind-wandering has a positive effect in the learning.

Purpose: This study is aimed to introduce the OPA-Kano method, an integrated version of OPA(Originality Practicality Analysis) and Kano's customer satisfaction method, and to examine its applicability. Methods: 30 ideas for smart phone accessories are generated using brainstorming and SIT(Systematic Inventive Thinking) and they are analyzed through the OPA-Kano method. For analysis, correlation method between OPA and Kano's results is applied for the ideas. Results: The results show that there is significant correlation between the OPA and Kano's approach, and the effectiveness of the proposed method is verified through the case of smart phone accessories. Conclusion: From the result of this study, we conclude that the proposed OPA-Kano method can be used for the evaluation of ideas and customer satisfaction.
