  • 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 design process of super water-saving toilet bowl system by the theory of inventive problem solving (TRIZ). The physical contradiction in TRIZ is defined far saving water in toilet bowl system with preventing the bad smell from septic tank. The super water-saving toilet bowl system is obtained by using the separation principle in time far resolving the physical contradiction. The real system is made using CAD tools. The consumption of water in the system implemented, is estimated about 3 ιcomparing with 13 ι of that in conventional toilet bowl system.

  • With the rapid development of urban suburbanization, a plenty of commercial operation of suburban environmental resource, the environment in suburb is more and more deteriorated. It also leads some passive effect on ecology, human, society and nature etc. At the same time, a serial of emergency rescue action has been implemented to decrease the deteriorating of suburban environment. For example, some important ecology nature reserves were built up; some compulsive protections have been put in practice for some key resource development region and gotten some good achievements. However, we still face the problem is that how to balance the contradiction between suburban environment resource development and conservation. It's necessary to introduce some western advantage management ideas, combined our actual situation, to find a way which is the most benefited to combine our country's suburb environment development and use.

  • QFD(Quality Function Deployment) is a very important tool to improve market share by reducing the gap between the voice of customer and the product's performance. But QFD is not a problem solving tool, although it is very useful in identifying what has to be solved or improved in order to meet the customer's desires. TRIZ has proved to be a very strong tool to solve the difficult problems that requires inventive thinking. QFD integrated with TRIZ becomes hot research recently. But merely linking between HOQ(House of Quality) in QFD and the contradiction matrix in TRIZ can not provide designers with a concrete method to solve the technical problem in the design process. Practically, the contradiction matrix and 40 inventive principles are not helpful for solving the technical problem. To solve the technical problem using TRIZ, a search for the tool and the object involved in the problem is made, from which the wanted result should be derived. A practical method to integrate QFD and TRIZ is proposed in this paper.

  • ATMS(Assumption-based Truth Maintenance System)는 추론기관의 추론 과정을 기억하고 각 추론 상태의 진위를 관리해주는 기능을 수행한다. ATMS는 JTMS나 LTMS와는 다르게 각 노드의 레이블과 Nogood들을 관리함으로써, 추론기관의 추론에 모순(Contradiction)이 발생하였을 때 이를 효과적으로 처리해준다. 기존의 ATMS는 모순에 영향을 주는 가정(Assumption)을 제거(Retract)함으로써 모순에 영향을 주는 원인을 제거하는 방식을 취하고 있다. 그러나, 본 논문에서는 이와 같은 방식으로 문제가 해결되지 못하는 새로운 종류의 모순을 설명하고 이를 처리하기 위해서는 ATMS가 추론기관과 연동하여 모순을 처리하는 방식에 대해서 서술하고자한다.

  • This paper revisits some old issues of irony, i.e., situational vs. verbal irony, and irony vs. paradox, in order to further clarify the issues. Although these issues seem to have been fully discussed, there are still unresolved and/or vague aspects that need to be accounted for. This paper also revisits the issue of theorizing the phenomenon of verbal irony, which has long been scrutinized by many philosophers and linguists including Aristotle, Grice, Sperber and Wilson, and recently, Utsumi and Attardo.

  • TRIZ was developed and refined in the Soviet Union between 1946 and 1985 by Genrich Altshuller. Its primary application has been for solving inventive problems in the areas of engineering. But, recently the elements of TRIZ began to be applied non-technical areas by Darrell Mann. TRIZ theroy was brought into South Korea in 1995 and it is used by the LG, SAMSUNG, POSCO. TRIZ is simply not the tool for technical problem solving, covering many areas of comprehensive approach is being recognized. TRIZ is a methodology for defining problem, finding root cause through RCA(Root cause analysis), defining technical contradiction and physical contradiction. TRIZ overcomes contradiction and purses problem solving method through innovation. TRIZ is a problem solving method in this study using the principles of non-technical fields applied to the improvement of the logistics area study. The method to overcome contradiction is 40 principles. It is possible to generate idea by using 40 principles. This study was applied to logistics field of non-technical area by using TRIZ principle.

  • Robert Venturi's theories like 'Complexity and Contradiction in Architecture' and 'Symbolism of Architecture' had a major impact on architects in postmodern culture and we could have his contextual understandings in those theories. In his early books, "Complexity and Contradiction in Architecture" and "Learning from Las Vegas", Robert Venturi showed theories related to context several times. But with looking at existing books or papers, we could barely see well-organized studies about his contextual understandings. So this study shows contextual approaches and thoughts with those theories, 'Complex and contradictory architecture', 'Architectural order and conventional architecture', 'Discontinuity in internal and external architecture', and 'Symbolism of architecture' in his two books. In those four theories, Venturi's contextual understandings are as fellows. To begin with, he developed contextual theories in architecture, understanding a whole building embracing each architectural factor, with architectural thoughts of complexity and contradiction. Second, he stressed architectural order to link each contradictory factor and used conventional architecture, as for existing common and ordinary things, to make available communication. Conventional factors were applied to urban viewpoints. Given the fact that contemporaries shared those factors, we could see contextual understandings in his approach. On top of that, unlike modern architects, he understood that functions of the inside and the outside were two different things. Based on contextual thoughts, he tried applying 'facade' that is one side providing an interface between in and out of a building to surroundings. Last, he wanted to express any meaningful connection between present and past, using symbolism in architecture. Presented by symbolism of architecture, architectural functions, architectural uses, historical meaning, ordinary factors, or something were also based on sharing in contemporary people. As the methodology to show these contextual factors, Venturi used an approach of symbolism.

  • Recently, the importance of creativity and problem-solving skills are being emphasized in engineering education. In particular, research is actively being conducted on learning models considering practicality or applicability in practice and education among many creative problem-solving methods. The objective of the present study is to develop a teaching and learning model and verify its effects in order to promote creative thinking and problem-solving skills using the TRIZ Contradiction Analysis. This study led the participants to obtain basic knowledge of creative engineering design through the creative engineering design course for freshmen at an engineering college, and come up with ideas and solutions using the TRIZ Contradiction Analysis. A survey was conducted and analyzed to verify the effectiveness of education using the proposed teaching and learning model, and as a result, the effectiveness of education has been proven by an average of 89 positive responses. Follow-up research is needed on improved application models so that the proposed learning model can be applied to various subjects.
