자동차 측면충돌시 인체의 상해를 줄이기 위하여 도어 시스템 부품 중에 도어트림이 충격을 차단하고 인체를 보호하는 역할을 하고 있다. 차체 판넬이 변형되어 도어트림에 전달되는 충돌 에너지를 패드가 흡수 하는데 중대한 기능을 한다. 이전에 충격흡수 패드는 외곽부위의 수평면에 의존하여 설계되었으며 이 구조는 점진적으로 충격을 흡수 하는데 문제점이 발견 되었는데 트리즈의 6단계 창의성 기법을 적용하여 패드의 주요 특성을 찾아내고 그 특성에 모순을 해결하여 차종에 적용할 수 있는 기본 단면과 설계 자유도가 높은 충격흡수부재를 개발 하였다.

가스의 수요가 늘어나면서 대량수요처에 대한 위험성과 안전성을 확보하기 위한 노력이 필요한 시점이다. 본 연구에서는 LPG저장탱크의 안전성과 경제성을 고려한 저장탱크를 파악하기 위하여 TRIZ 기법을 활용하였다. 지상형은 화염 등에 의한 위험성이 높으며, 지하매몰형은 부식 등에 의한 경제적 손실이 크다. 따라서 지상형과 매몰형에 대한 문제점을 해결하기 위해 6SC(6 Step Creativity)을 응용하였으며, 그 결과 지하격납형을 도출하였다.

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 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 external inspection and packaging stages of products used in the semiconductor manufacturing process, there is a problem in which particles are adsorbed to the product itself or a carrying tool due to electrostatic discharge. This study presents a methodology that can improve the problem of adsorption of particles to a product by using a practical TRIZ technique. By applying the proposed practical TRIZ-based methodology, the problem was defined, and contradictions caused by product waiting time were derived. Among the derived contradictions, physical contradictions were set and the concept of 'space separation' was applied to derive solutions such as 'installation of Ionizer' and 'improvement of the layout of the workroom'. As a result of the experiment by applying 'Ionizer Installation' and 'Workroom Layout Improvement' derived through the application of practical TRIZ, it was confirmed that the particle adsorption problem that occurs during the waiting time of the product can be solved.Through this study, it is expected that workers, facility engineers, and technical engineers working at manufacturing processes will be able to effectively solve the problems they face through creative thinking and change of ideas by using practical TRIZ techniques, and contribute to innovative technology development and productivity improvement.

LPG(Liquefied Petroluem Gas) Vehicles in metropolitan area being applied to improve air quality and have been proven effective for the reduction of air pollution. These gas stations are required to safe the storage tank because of possibility of causing huge loss of life and property. While storage tanks above ground have potential risk of explosion if fire breaks out and those under-ground are difficult to inspect due to poor accessibility neither above nor under-ground tank can serve us well. This study used the RPS-TRIZ (Rapidly Problem Solving-Teoriya Resheniya Izobretatelskikh Zadatch) technique and suggested the use of under-ground containment storage tank as a solution for safety issues and safety inspection.

In this study, we wanted to apply the creative problem-solving theory of TRIZ to explore the possibilities of applying it in fashion design as well, and to develop a creative bag design so that one product design can be transformed into a form for another purpose. Through TRIZ's 4 invention principles, Local Quality No. 3, Universality No. 6, Nesting No. 7, and Another dimension No. 17, the solution was derived and applied, and the final design was developed, and it was found to satisfy the functionality and usability of 2 types of bag form and apron shape. Accordingly, it was confirmed that TRIZ as an invention principle technique can be fully utilized in fashion design. It is hoped that it will increase the possibility of developing a converged design in the future and be used as a basic example material for designing products that are highly utilized in everyday life.

In the TFT-LCD(Thin Film Transistor-Liquid Crystal Display) panel manufacturing industry, SAMSUNG, a late entry, can catch up to leading first mover, SHARP. The changes the note, monitor, TV, and mobile markets in the TFT-LCD industry were studied using a system analysis method. In addition, the fast response time technology in SAMSUNG TFT-LCD technology was developed using the TRIZ method. For example, a new liquid crystal mixture of a wide view angle and fast response time were developed by doping a new high birefringence liquid crystal material in a base mixture using the contradiction method and su-field method of TRIZ. The response time of a new liquid crystal mixture was improved to approximately 60%(16.2ms with base LC mixture, 9.8ms with a new LC mixture).

트리즈는 처음에는 기술 분야에서 사용되었으나 현재는 창의적으로 문제를 해결하기위해 교육, 문화 등 비 기술적인 부분에서도 많이 연구되고 있다. 프로그래밍 교육방법에서도 가능한 대안을 생각해보고 오류를 검증 및 수정하는 과정에서 창의적인 사고과정이 포함되어 있다. 따라서 프로그램밍 교육에도 트리즈의 원리를 사용한다면 확산적 사고를 증진시키는 프로그래밍을 교육할 수 있을 것이다. 이에 본 연구에서는 트리즈의 40가지 발명원리를 활용한 프로그래밍 교육을 제안하였다. 프로그래밍 교육에 트리즈의 발명원리를 적용하여 프로그래밍에 다양한 방법을 시도하는 창의적인 프로그램 교육이 가능할 것이다. 추후에 프로그래밍 교육을 위한 더 다양한 트리즈의 원리를 활용하는 교육방법 연구가 필요하다.

In order to reduce the cost and weight of the soft-foamed instrument-panel (IP), it was developed the new IP which is made by the two kinds of injection methods. One is the compression-injection with back-foamed foil inserted, and the other is two-shot injection with the passenger airbag door. We named it 'IMX-IP' which means that all components ('X') of the IP with different resins are made in a mold. The development procedure of this technology was introduced (1) Design of the new injection mold through TRIZ method, (2) Optimization of the injection conditions and back foamed-foil for minimizing the foam loss and thickness deviation, (3) Development of CAE for two-shot injection compression, (4) Reliability performance test and application to the mass production. The reduction of the processes through the two-shot injection with back foamed-foil inserted made it possible to enhance soft feeling on IP and reduce the cost and weight simultaneously.
