Recently, paradox management is a new paradigm to solve the management dilemmas. This is a new perspective and a creative way of thinking to draw the synergic effect by pursuing simultaneously the conflicting elements. As one method for the paradox management, this paper proposes a process of combining the TOC (Theory Of Constraints) and TRIZ (Russian Theory of Inventive Problem Solving) and applies to a dilemma case in business environments.

There are no products, systems to manage health and detect security for infant, the old and the weak in Korea. Recently, the concerns of parents are increasing more about all of children(baby, infant, etc) because rate of birth is decreasing gradually. Also, the average span of human life is on an increasing trend according to well-being and evolution of medical treatment. Therefore, this treatise analyzed problems in managing and following-up infant, the old and the weak at present. By using TRIZ to solve problems, we devised new conceptional ideas, detail designs to manage health, detect security, cope with correspondences for them and developed the prototype and tested it. Excellent performances are proved through various field test.

Axiomatic Design has been developed as a general design framework during past two decades and TRIZ has been developed for a design tool over 50 years. Axiomatic design is quite excellent in that the design should be decoupled. When a design matrix is established, the characteristics of the design are identified concerning the coupling properties. If the design is coupled, a decoupling process should be found. However, axiomatic design does not specifically indicate how to decouple. In this paper, a design method is developed to use TRIZ in the decoupling process. The decoupling ideas are extracted from the substance field analysis and various methods in TRIZ. The mettled is applied applied to the conceptual design of a beam splitter for the laser marker and the results are analyzed.

창조와 혁신이 성공의 중요한 키워드로 대두되면서 창의적 문제해결 방법론인 트리즈(TRIZ)에 대한 관심이 고조되고 있다. 지금까지 트리즈는 전자 및 기계분야에 도입되어 제품혁신의 원동력으로 활용되고 있어, 본 연구에서는 미래유망기술인 바이오분야에 트리즈 기법을 적용하여 문제를 해결하고 혁신적인 연구개발을 추진할 수 있는지의 가능성을 타진해보고자 하였다. 바이오분야 연구 중 홍삼제조과정에서 발생하는 문제를 선정하고, 이의 문제와 문제원인 구분 및 모순을 도출하고 트리즈의 발명 40가지 원리를 적용하여 홍삼 제조과정에서 발생되는 갈라짐 문제를 해결하고자 하였다. 홍삼은 수삼을 스팀 등의 방법으로 쪄서 익혀 말린 담갈색의 인삼으로, 홍삼의 갈라짐은 유효성분의 유출과 외형등급 하락으로 상품성을 떨어트리는 주요 원인이 된다. 트리즈 툴(Tool) 중 모순 매트릭스 및 브레인스토밍을 통해 적용 가능한 발명원리를 도출하고, 실험을 통해 홍삼 제조과정에서 갈라짐을 방지할 수 있는 유용한 방법들을 제안하였다.

본 연구는 과학혁명 시기의 창의적 과학자 중 한 명인 Hooke의 생애와 업적을 통해, 오늘날 과학교육에서의 발명교육에 대한 시사점을 제시하고자 하였다. 이에 Hooke에 의해 출간된 저서와 논문을 중심으로 그의 업적과 창의적 문제해결 과정을 통해 나타나는 특징을 범주화하고 영향을 미친 배경이 무엇인지 논의하였다. 연구 결과, Hooke는 일상적 맥락에서 관찰가능하고 통용되는 사실을 기반으로 과학적 추론을 시도하였으며, 실제 관찰과 탐구에 필요한 다양한 도구와 방법들을 직접 제작하고 이를 적극적으로 활용하였다. 다른 과학자들과 구분되는 Hooke의 발명에 관한 천재성은 호기심을 자극할 수 있는 주변 환경과 그의 예술적 재주, 그리고 다양한 분야에 대한 관심을 이끈 스승과 동료들이 있었기에 가능했다. 또한 과학적 이론과 관찰 가능한 실재 사이의 일원론적인 세계관을 지지함으로써 실물 및 도구의 제작을 통한 이론의 창안을 시도하였다. 이에 본 연구에서는 이를 토대로 오늘날 과학교육에서 발명교육을 연계한 실천방안과 시사점을 제시하였다.

설계VE 과정에서 아이디어 창출은 가장 중요한 부분이다. 그러나 아이디어 창출은 일반적으로 설계VE 팀원의 지식이나 경험을 통하여 진행되게 된다. 설계VE 워크샵에서 좋은 성과를 내기 위해서는 단순하게 설계VE 팀원의 지식이나 경험에 의존하는 것이 아니라 보다 체계적인 접근방법이 필요하게 된다. 본 연구에서는 설계VE 워크샵에서 사용할 수 있도록 TRIZ의 모순충돌 개념을 활용한 체계적인 아이디어 창출방법을 제시한다. 연구과정에서는 TRIZ의 모순충돌 개념을 바탕으로 설계가 가지는 문제영역을 정의하고, 기술적 요인을 활용하여 모순충돌을 나타냈다. 아이디어 창출과정에서 기술적 요인은 설계기능을 향상시키기 위한 체계적 방법론으로 활용됐다. 가시설 공사에 대한 시범사례에서는 본 연구에서 제시한 아이디어 창출절차를 적용할 경우 설계가치를 향상시킬 수 있다는 것을 시범적으로 제시했다.

A creative innovation and an innovative problem-solving of industrial companies can be achieved by overcoming the challenges of technical and physical contradictions. The approaches to address conflicting and paradoxical problems, such as technical and physical contradictions have a crucial role in advancing the quality assessment for manufacturer and service provider. The term, technical contradiction, depicts the state that improvement of one ends of IFR (Ideal Final Result) leads to unfavorable condition of the other ends, and results in conflicting problem. Another type of contradictions that's discussed in this study is a physical contradiction which is due to two mutually opposing states of the means of ends, and gives paradoxical situation. By integrating the means-ends chain perspectives, the physical contradiction that is a specifically root-causes, "means", can be initially addressed to resolve the downstream problem of technical contradiction which represents a general and abstract goals, "ends". This research suggests IFR resolution processes to handle both physical contradiction of means and technical contradiction of ends by employing causal relationship with IFR, effects and causes. In summary, the study represents three major processes that resolve such contradictions are demonstrated as follows: 1) Derivation of causal and hierarchical relationship among IFR, ends and means by considering CAED (Cause-And-Effect Diagram) and LT (Logic Tree). 2) Identification of causal relationship between physical contradiction and technical contradiction by using TPCT (TRIZ Physical Contradiction Tree) and TCD (Technical Contradiction Diagram). 3) Application of integrated TRIZ principles by classifying 40 inventive principles into 4 general conditions of the separation principle of mutually opposite states in space, in time, based on conditions, and between the parts and the whole. In order to validate the proof of proposed IFR resolution processes, the analysis of the TRIZ case studies from National Quality Circle Contest in the years, 2011 to 2014 have been proposed. The suggested guidelines that are built based on TRIZ principles can uniquely enhance the process of quality innovation and assessment for quality practitioners.

Bollard installed on the street is a facility that protects pedestrians by restraining cars from entering on the sidewalk. It is basically classified into manual, semiautomatic, automatic type and mostly manual type is widely used because the automatic type is imported and much expensive. However, in case of manual handling type in practice, it is very troublesome and difficult to remove it whenever cars are permitted, and in case of automatic type, since underbody of a bollard is very long, it is difficult to dig a deep hole in the ground because a pipe, a hose or a cable is under the surface. In order to reduce these difficulties, this paper proposed new design of the multistage bollard that moves up and down automatically by using hydraulic system. This is developed by 6 step creativity of TRIZ inventive problem solving and structural analysis. The developed bollard can be installed in shallow hole and allow entry of vehicles through up-and-down movement without its removal manually. Finally, we could see smoothly motion through the manufactured bollard.

Axiomatic Design has been developed as a general design framework during past two decades and TRIZ has been developed for a design tool over 50 years. Axiomatic design is quite excellent in that design should be decoupled. When a design matrix is established, the characteristics of the design are identified according to the coupling properties. If the design is coupled, a decoupling process should be found. However, axiomatic design does not specifically indicate how to decouple a coupled design. In this research, the coupling manner is classified into six patterns. Each pattern could be solved by an appropriate TRIZ module. A table, which matches the coupling pattern and a TRIZ module, is proposed for effective application of the two design theories. The decoupling ideas are proposed by using TRIZ modules. When the number of decoupled designs is more than one, the engineer should select the final idea. The proposed method is applied to practical cases such as a tape feeder and a beam adjuster of the laser marker.
