To improve the productivity of cargo containment construction for a membrane LNG carrier, it is important to shorten the installation period and process of the scaffolding system, which is a construction workbench of a cargo containment for a membrane LNG carrier. As an effective method, opinions are being gathered to enlarge the lifting unit from the existing two stages to eight stages. On the other hand, the stresses around the pin and hole will increase significantly because of the increase in lifting load according to the large size of the module. The purpose of this study was to establish a new large module-lifting plan by introducing TRIZ to solve these problems. This study adopted a method to utilize 40 inventive principles, which is one of the various problem-solving tools of TRIZ. First, technical contradictions were derived, the engineering parameters were selected. Second, efficient inventive principles were selected to overcome the technical contradictions using a contradiction matrix. Finally, the general and specific solutions were derived through the selected inventive principle, and structural analysis confirmed that the stress generated in the structure was low. The utility of TRIZ was confirmed by the successful lifting of large modules using the established lifting method.

일반적으로 실무에서 공학적인 상충(Trade-offs)의 문제를 해결하는 가장 대표적인 방법론으로 트리즈(TRIZ)가 있다. 지금까지 트리즈관련 연구에 의하면 공학적 파라미터간의 모순을 해결하는 데는 트리즈의 유용성이 이미 확인되었다고 볼 수 있다. 하지만 제품 설계에 있어 트리즈의 사용 범위를 반드시 공학적인 파라미터간의 모순을 해결하는 데 사용을 국한시킬 필요는 없다. 관점을 달리하여 선행설계 엔지니어가 처음부터 소비자의 요구사항에 대한 컨조인트(Conjoint)단계에서 모순을 푼다면 공학적인 문제로 환언(Reduce)시키거나 분화(Breakdown)시켜 제한조건하에서 지엽적이고 복잡한 모순 문제를 풀지 않아도 될 것이기 때문이다. 본 논문에서는 고객 니즈 중심의 컨조인트와 공학 파라미터 모순 해결의 트리즈의 사고를 자연스럽게 연결하기 위해서 제약이론(TOC)의 갈등해소도(CRD : Conflict Resolution Diagram)를 도입하도록 한다. 갈등해 소도는 목적을 달성하기 위해 전행조건의 갈등요소를 확인한 후 타협안을 찾지 않고 잘못된 가정을 엎을 대책으로서 주입(injection) 제시하여 목표를 달성하는 방법이다 따라서 컨조인트의 고객 니즈 최적화를 달성하기 위해 세부 고객 니즈의 갈등요소를 확인하고 트리즈를 주입시켜 제품 설계 목적을 달성할 수 있게 적용하고자 한다. 본 연구의 목적은 첫째, 제약이론(TOC)의 사고를 바탕으로 트리즈를 이용하여 고객니즈의 모순관계를 해결하는 진보된 컨조인트 방법론을 제시하는 것이다. 이 방법론을 앞으로 Conjoint-TRIZ라 표기하도록 하겠다. 둘째, 본 연구에서 제시한 Conjoint-TRIZ 방법론을 자동차 인테리어 설계의 새로운 접근법으로 적용을 시도하여 그 유용성을 검증한다.

This study aims to recognize that creative thinking methodologies can be adopted in the spatial design. The concept of 'Convergent' and 'Divergent' used in structure of intellect model by Guilford is chosen to understand the character of creative thinking methodologies. Technical and physical contradictions is analyzed for '40 inventive principles' of TRIZ and spatial design works. Through this study, we recognize that the creative thinking methodologies consist of analysis, idea generation and evaluation phase. The psychological inertia that limits the creative thinking should be move away from solving problem, and convergent and divergent thinking have peculiarities to be adopted in condition and to be harmonized, and to set the direction of solving technical problems through to reach the target point integrated way of thinking is needed. '40 inventive principles' by Altshuller are based on engineering and useful in many areas of fields. However some principles are not accepted in design process because these are not considered in design field and paradigm is changed from machine to nature. Nowadays, nature is a prime issue for sustainable human life, because it has sustainable recycle structure and saving energy ways. Thus, creative thinking, including TRIZ is useful in design education and progress, and should be an essential element to get a new design paradigm.

Various drones have extended application area very fast. In this paper, we define two contradictions in designing a portable-size drone by using TRIZ technique. The first is a physical contradiction between high rigidity and good portability, and the second is a technical contradiction between high stability and good portability. Through TRIZ technique, six design principles, which guide direction for optimal design, were driven. Consequently, an umbrella mechanism and design criteria were proposed for a portable-size drone. Detail design is verified through finite element method. Test results for the portable-size prototype drone show good performance, and prove its usefulness to be equivalent to a general full-size drone.

This paper presents a study on the design for contamination preventation system of solar battery. The system of contamination preventation has an wind amplifier. Wind amplifier is conceptually designed by using TRIZ. The surface of solar battery is covered with dust during accumulate the energy. The dust cause reduce power of photovoltaic module and efficiency drop of photovoltaic system. Reflect and absorb of incident ray are caused by the dust on surface of solar battery. The solution of this problem has been derived using 6SC(6 steps creativity)TRIZ. The wind amplifier which has structure such as funnel shape. The incident wind in the wide hole is amplified by the gate become narrow. The system of contamination preventation with wind amplifier which mounted on the side of the solar battery surface reduces the reflect and absorb and improve the efficiency of photovoltaic system.

Patents have been recognized as a core knowledge asset which are closely related with company's technological competitiveness. However, only a small portion of patents are actually contributing to the profit of the company. In addition, it costs a lot of money continuously to maintain the patent rights regardless of their values. Thus, effective methodologies are required to create patents with high values. It is examined what kind of differences exist between high value patents and the others in the use of TRIZ methodologies. For the purpose, we analyzed the US granted patents of Samsung Electronics. The analysis shows that there is no significant difference in the use of inventive principles, but high value patents utilize 'separation by condition' the most where as the others 'separation by space' the most frequently in the use of separation principles. In the use of standard solutions, high value patents use the 'class 2' principles frequently than the others.

This study the problem of deposition uniformity observed during Mist-CVD deposition experiments. The TRIZ's ADRIGE algorithm, a problem-solving technique, is utilized to systematically analyze the issue and propose solutions. Through problem and resource analysis, technical contradictions are identified regarding the precursor's volume and its path when it encounters the substrate. To resolve these contradictions, the concept of applying the principle of dimensional change to transform the precursor's three-dimensional path into a one-dimensional path is suggested. The chosen solution involves the design of an enhanced Mist-CVD system, which is evaluated for feasibility and analyzed using computational fluid dynamics. The analysis confirms that the deposition uniformity consistently follows a pattern and demonstrates an improvement in uniformity. The improved Mist-CVD equipment is validated through analysis, providing evidence of its feasibility and yielding satisfactory results.

In the 21st century, The service industry is becoming a new core business. In the modern industrial society, it escapes from supporting the manufacturing industry and finally leads to the growth of the manufacturing industry. Although many companies have met a variety of customer requirements through the existing service process, an organization or service developer has been failed because they had depended on intuitive judgment. Therefore, in this paper, we suggests CSIM(Case-based Service Improvement Methodology) to support improvement direction. This methodology is based on 120 cases and developed by utilizing the TRIZ concepts. As a result, CSIM will be a creative tool to support a developer to solve the problems.
