This paper presents a new design algorithm for piece-removing dynamical system, based on 6-Sigma DMADOV technique using ARIZ and Brainstorming. Our design target is the piece-removing system installed on a mobile platform of bead-grinding equipment. The 6-Sigma DMADOV technique guides us design process according to 6 steps, i.e., Define - Measure - Analyze - Design - Optimize - Verify. A Design strategy to reduce the weight of piece-removing dynamical system will be explored by using ARIZ, i.e.,(the abbreviation of Algorithm for Inventive Problem Solving in Russian). The ARIZ will result in a final solution that the height and angle control parts for a cutting tool should be replaced by a kinematical approach, rather than complicated mechatronic approach(using motors). The Optimize step is composed of two sub-steps: (i) Generating process for obtaining several ideas of piece-removing system by using Brainstorming technique, satisfying the final solution derived from the Design step using ARIZ, and (ii) Optimizing process for selecting the most optimal idea of piece-removing system by using Pugh's matrix from the viewpoints of weight, cost and accuracy. The laststep of Verify has shown that the final design obtained by the 6-Sigma DMADOV technique with ARIZ & Brainstormingcan improve an initial design with design requirements satisfied. In this paper, we have shown that ARIZ and Brainstorming can be cooperatively merged into 6-Sigma DMADOV to give us both a formulatedproblem-solving approach and diverse candidate solutions(or ideas) without trial-and-error efforts.

Korea's Corona 19(COVID-19) quarantine, referred to as 'K-Quarantine', is a globally recognized quarantine system that has achieved both conflicting goals: health and economy. The quarantine system represented by 3T(Test-Trace-Treat) is not a method of blocking an area, but a method of screening and treating infected and non-infected persons. The screening center, one of the key elements of this screening treatment system, has evolved to suit the timing and situation of COVID-19, and has succeeded in initial response by conducting large-scale tests quickly and safely. By analyzing the evolution of screening centers that produced such significant results from a problem-solving point of view, it proved its meaning as a practical success case of creative problem-solving. In addition, the usefulness of TRIZ (Russian abbreviation of Theory of Solving Inventive Problem), a creative problem-solving theory, was confirmed through an analysis of actual verified cases of COVID-19 response. TRIZ is a problem-solving theory created by analyzing the regularity of invention patents, and is widely used not only in the technical field but also in the non-technical fields such as design, management, and education. The results of this study are expected to provide useful meaning and practical examples to researchers interested in system analysis and TRIZ application from a problem-solving perspective.

It is very necessary to have a creative problem-solving capacities to learn various majors and liberal arts based on the major, and to solve the bottleneck techniques led by students. In this study, the existing creative problem-solving curriculums, 'Methodology of Inventive Problem Solving' based on TRIZ, were improved and applied, and industrial bottleneck techniques were provided to students to solve these techniques. To improve the curriculum, 1) improvement of instructional objectives and learning contents, 2) improvement of evaluation methods and contents (reflecting the evaluation of instructor and students), and 3) learning satisfaction survey were conducted in the following order. As a result of the application of the improved curriculum, the level of activities for each team was improved, and when the core process was well understood, the evaluation of team activities was also excellent, but there was a tendency to focus on methods that are relatively easy to apply in the problem solving process. In the final exam (learning contents evaluation), teams with difficult understanding of the TRIZ theory or low team activities showed a relatively high trend, but the difference in level between divisions was slightly reduced.

A camp program where the theory of inventive problem solving TRIZ is applied to real problems of the industry was developed and taught at a five-day seminar apart from the standard curriculum at a university D in Gyeonggido. This study focuses on the educational effect that the TRIZ method has on the engineering students when their creative problem solving skills are required to solve industry problems on their own with the knowledge from their courses. For five days, the students were educated about TRIZ and assigned a real industry problem "Removal of friction caused by bubble formation in water heating pipelines". By applying TRIZ to the problem, the students developed an "Air removing Air Arrester" which received the evaluation, "with understanding the system architecture and the task objective causes and formation of the problem could be handled which directly helps the company's R&D". In this case, TRIZ offers the students a guideline and knowledge on how to approach problems and as a result the students provided a practical solution. During the process, the TRIZ method instilled confidence in the students and proved to be a motivation. It becomes obvious that this short-term program has a positive effect on students' way of thinking creatively and increasing their problem-solving abilities.

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".

멤브레인(membrane) LNG 운반선 화물창(cargo containment) 공사의 생산성 향상을 위해서는 공사 작업대인 비계 시스템(scaffolding system)의 설치 기간 및 공정 단축이 요구된다. 이를 위한 효과적인 방안으로 모듈의 탑재 단위를 기존의 2단에서 8단으로 대형화하자는 의견이 수렴되고 있다. 하지만, 모듈의 대형화로 인해 탑재 하중이 증가하면 메인 수직 파이프를 연결해주는 핀(pin)과 홀(hole) 주위에 국부 응력이 증가하여 재료의 항복응력을 초과하게 되는 문제점이 발생한다. 본 연구의 목적은 이러한 문제점을 해결하기 위해 트리즈(TRIZ)를 도입하여 새로운 대형 모듈의 탑재 방안을 수립하는 것이다. 본 연구에서는 트리즈의 여러가지 문제해결 도구 중 하나인 40가지 발명원리를 활용하는 방안을 채택하였다. 먼저 기술적 모순을 도출하고, 공학변수를 선정하였으며, 모순행렬을 활용하여 기술적 모순을 극복하기 위한 효율적인 발명원리를 선정하였다. 선정된 발명원리를 통해 일반해결안 및 특정해결안을 도출하였고, 구조해석을 통해 구조물에 발생하는 응력이 낮은 수준임을 확인하였다. 수립된 탑재 방안을 적용한 대형 모듈의 실제 탑재에 성공함으로써 트리즈의 유용성을 확인하였다.

In design education enhancement of design methodology and creativity can be stimulated through taking on several creative roles within an interactive and enjoyable studio course. To overcome blocks to creativity I developed a intermediate course, 'Furniture Design Studio I' at the sophomore advanced level course. Inventive thinking and a sense of aesthetic are the essential element for all studnets to grow as a professional designer. And to develop their creative thinking skill I introduced a system that utilizes each element into a role-playing type of projects. Students will be able to demonstrate their underlying creativity in a more open environment. Instead of stressing to solve a lot of complicate issues, the main focus is to allow freedom of expression and creativity. Role-playing are executed in a design studio environment rather than in a psychodrama situation. There are two different type of role-playing : Inventor and Designist (Designer + Artist). Students will be able to work in groups, incorporate problem solving into their projects and concentrate on more personal creative form developments. Through this process, students will enhance their problem solving abilities and broaden their scope for innovation. Thus increases the student's participation and creativity. Investigating the problems of domestic design education through these sort of special programs and developing systems that enhance creativity based on the results and the process methods.

창의적 문제해결 이론인 트리즈는 기계나 전기, 전자 등과 같은 전통적인 공학 분야에서 널리 활용되어 좋은 성과를 거두고 있으나, 아직 소프트웨어 분야에 적용된 사례는 많지 않다. 하지만 소프트웨어도 다른 어떤 분야 못지않게 창의적 문제해결 역량이 요구되는 분야이므로, 트리즈를 활용한다면 놀랄 만한 성과를 얻을 수 있을 것으로 예상된다. 따라서 본 논문에서는 트리즈를 적용해서 스마트 클리커라는 새로운 소프트웨어를 개발해 봄으로써 소프트웨어 분야에서는 트리즈를 활용하기 어렵다는 심리적 타성을 타파하고, 소프트웨어 분야에서 트리즈를 활용하는 접근방법을 제시하였다.
