The problems having contradiction relationships are difficult to solve because the contradiction relationships of the problems frequently cause dilemmas that are in a double-bind. Most creative and innovative examples solved contradictions inherent in the dilemmas. TRIZ provided the concept of physical contradiction as a common problem solving principle in inventions and patents. Also, TRIZ provided 4 separation principles for solving physical contradictions; (1) separation in time, (2) separation in space, (3) separation within a whole and its parts, (4) separation upon conditions. However, there have not existed accurate definitions of the separation principles of TRIZ. Thus, many TRIZ researchers have proposed various kinds of interpretations about the separation principles. In addition, it could be easily recognized that the 4 separation principles are the only way for solving physical contradictions. This paper firstly classifies the types of contradiction relationships and the contradiction solving dimensions based on the Butterfly model for contradiction solving. Secondly, this paper compares and analyzes the cases for each contradiction relationship type. The contributions of this paper lies in overcoming the bounded rationality about problem resolutions because we can reduce the problem space as much as we recognize the structures and the types of contradiction problems.

Innovative Contradiction Solving Dimensions and Algorithms

현정석,박찬정 한국정보기술학회 2017 JOURNAL OF ADVANCED INFORMATION TECHNOLOGY AND CON Vol.7 No.2

In engineering fields, many researchers have confronted with various kinds of difficult problems to solve. In particular, when there exist conflicting requirements to be satisfied at the same time, the complexity of problems increases. To solve the problems creatively and innovatively, many useful methods have been developed. Among them, TRIZ has also been used at many companies and institutes. TRIZ is a the theory of inventive problem solving. However, it is based on induction-based method. Even though many TRIZ researchers tried to reduce trials-and-errors as many as possible, there still exist trials-and-errors in its algorithm. In this paper, we propose an algorithm for solving contradiction problems systematically. Our algorithm is based on propositional logic and deduction, and thus we can automate it with a computer programming language. We have used this algorithm in educational areas, and we show the results about the academic achievements from applying the algorithm in this paper. In the future, we can apply the proposed algorithm to computers for solving contradiction problems automatically.

Butterfly Chatbot: Finding a Concrete Solution Strategy to Solve Contradiction Problems

현정석,박찬정 한국정보기술학회 2019 JOURNAL OF ADVANCED INFORMATION TECHNOLOGY AND CON Vol.9 No.1

The Butterfly model, which aims to solve contradiction problems, defines the type of contradiction for given problems and finds the problem-solving objectives and their strategies. Unlike the ARIZ algorithm in TRIZ, the Butterfly model is based on logical proposition, which helps to reduce trial and errors and quickly narrows the problem space for solutions. However, it is hard for problem solvers to define the right propositional relations in the previous Butterfly algorithm. In this research, we propose a contradiction solving algorithm which determines the right problem-solving strategy just with yes or no simple questions. Also, we implement the Butterfly Chatbot based on the proposed algorithm that provides visual and auditory information at the same time and help people solve the contradiction problems. The Butterfly Chatbot can solve contradictions effectively in a short period of time by eliminating arbitrary alternative choices and reducing the problem space.

모순해결과 나비모형에 대한 교육이 청소년들의 문제해결력에 미치는 영향

현정석,박찬정 한국과학영재교육학회 2010 과학영재교육 Vol.2 No.3

트리즈(TRIZ)는 창의적으로 문제를 해결할 수 있도록 안내하는 체계적인 알고리즘이다. 최근 교육을 비롯한 여러 분야에서 창의적 문제해결력이 화두가 되면서 많은 학자들이 브레인스토밍이나 여섯 색깔 모자 기법 등과 같은 창의적 문제해결기법에 관심을 가지고, 이를 여러 분야에 적용하고 있다. 본 논문에서는 J 과학영재교육원에 재학 중인 중등 학생들에게 트리즈 교육을 실시한 후, 이 교 육이 영재 학생들의 문제해결력에 어떤 영향을 미치는지 효과를 분석하고자 한다. 트리즈 교육 후, 학생들이 참여하게 된 발명대회에서의 성과 및 특허 출원과 관련된 내용을 위주로 기술하고, 어떤 개 선점이 있었는지도 설명한다. 또한, 향후 문제해결 사고(computational thinking)와 연결시켜 바람직한 교육 방안을 모색하고자 한다. TRIZ is a systematic algorithm for guiding students to the right way to solve given problems creatively. Recently, creative problem solving has become onf of the hot issues in various areas including education. Thus, many researchers have been interested in the techniques such as brainstorming, six thinking hats, and so on to apply these methods to various problems. In this paper, after we give lectures about TRIZ to the gifted students belong to the Institute of Science Education for Gifted Students in J University, we analyze the educational effects on their problem solving abilities. We especially develop the education model, namely Butterfly model, for the students to learning easily and quickly. Thus, we also teach them by using our Butterfly model when they solve problems. In addition, in this paper, we describe the outcomes such as patent applications and an invention competition's awards our students get. Finally, we suggest a desirable way connecting to the computational thinking when we teach adolescents about creative problem solving.

공리적 설계의 독립공리를 위배하는 사례분석과 모순해결 원리

현정석,박찬정 한국경영컨설팅학회 2019 경영컨설팅연구 Vol.19 No.3

Axiomatic Design provides quantitative criteria to evaluate whether a design is good or bad. Research works on Axiomatic Design have been based on the independence axiom. The independence axiom suggest that the uncoupled design is optimal, in which the number of functional requirements are the same as the number of design parameters, which are the physical characteristics, and each design parameter performs its function requirement independently of each other. In the Axiomatic Design, it is suggested that no case of violating the independence axiom of Axiomatic Design has been found yet. This paper analyzed the cases that were solved optimally without satisfying the independence axiom of the Axiomatic Design from the perspective of solution of contradiction. First, even though the number of function requirements and the number of design parameters are matched, partial design parameters are combined to constitute the whole design parameters. Therefore, the partial design parameters and the whole design parameters are interdependent and violate the independence axiom. This paper analyzed Duncker 's radiation problems and cart wheel cases climbing stairs. Second, although the number of design parameters is less than the number of functional requirements, which corresponds to a coupled design, there are cases where there are optimum points that satisfy two conflicting functional requirements. This paper analyzed the short-run cost curve in Economics and the bias-variance trade-offs in Machine Learning. Third, if a problem is the case that its design parameters are perfectly dependent of each other and have a -1.0 correlation, the problem may be resolved optimally. This paper analyzes Markowitz 's portfolio theory, which is based on the correlation of investment alternatives. Markowitz's portfolio theory presents an optimal portfolio for achieving the two functional requirements for expected return and risk for investment alternatives. According to the theory, when the investment alternatives are not mutually independent and have a -1.0 correlation, they can completely eliminate the risk without lowering the expected return on the investment alternative. 공리적 설계는 어떤 설계가 좋은지 나쁜지 평가할 수 있는 정량적인 기준을 제공한다. 공리적 설계에 관한 연구들은 독립공리를 바탕으로 이론을 전개했다. 독립공리는 기능적인 요구사항의 수와 물리적 특성인 설계 요소의 수가 일치하면서 아울러 각 설계 요소가 상호 독립적으로 기능적인 요구사항을 수행하는 비연성 설계(uncoupled design)가 최적이라고 제시한다. 공리적 설계에서는 지금까지 공리적 설계의 독립공리를 위배한 사례가 발견되지 않았다고 제시하였다. 본 연구는 공리적 설계의 독립공리를 충족하지 않아도 최적으로 문제가 해결되는 사례들을 모순해결 관점에서 분석하였다. 첫째, 기능적인 요구사항의 수와 설계 요소의 수가 일치할지라도 부분적인 설계 요소들이 모여서 전체 설계 요소를 구성하기 때문에 부분적인 설계 요소와 전체 설계 요소는 상호의존적인 관계를 가져 독립공리를 위배하게 된다. 본 연구는 Duncker의 방사선 문제와 계단을 오르는 카트 바퀴 사례를 분석하였다. 둘째, 기능적인 요구사항의 수보다 설계 요소의 수가 작아서 연성 설계(coupled design)에 해당하지만 한 개의 최적점에서 상충된 두 가지 기능적인 요구사항들을 충족하는 때도 있다. 본 연구는 경제학의 단기비용곡선과 기계학습의 편향-분산 트레이드오프 사례를 분석하였다. 셋째, 공리적 설계의 독립공리와 달리, 설계 요소들이 상호 독립적이지 않고 완벽하게 –1.0의 상관관계를 갖는 경우에 오히려 최적으로 문제를 해결하는 때도 있다. 본 연구는 투자대안들의 상관관계에 따라 투자 위험이 달라지는 Markowitz의 포트폴리오 이론을 분석하였다. Markowitz의 포트폴리오 이론은 투자 대안의 기대수익률과 위험에 대한 두 가지 기능적인 요구사항을 달성하는데 최적의 포트폴리오를 제시한다. 그의 이론에 의하면 투자대안들이 상호 독립적이지 않고 –1.0의 상관관계를 가질 때에 투자대안의 기대수익률을 낮추지 않으면서도 위험을 완전히 없앨 수 있는 것으로 나타났다.

Application of the Butterfly Diagram for Business and e-Commerce Innovation Cases

현정석,박찬정,강재정,하환호 한국인터넷전자상거래학회 2014 인터넷전자상거래연구 Vol.14 No.5

Innovative cases have something in common that they solved contradiction relations hidden in given problems. General Motor’s Installment Financing, Diffie-and-Hellman’s public key cryptography, Toyota’s Just-In-Time production system, and SK Telecom’s Gifticon are the examples. In order to solve problems, it is important to represent the problem with an appropriate notation. However, we hardly found the systematic representation method for the contradiction problems belong to business and e-Commerce innovations. When we confront a difficult problem to solve, if we can figure out the problem structure and the problem type, then we can easily solve the problem because they help to reduce the problem space. In this research, we present the Butterfly Diagram for contradiction problem solving to draw innovative problem solution strategies by analyzing the trade-off relations and the contradiction relations hidden in dilemmas. In addition, we proposed a few implications by applying the Butterfly Diagram for contradiction problem solving to the business and e-Commerce innovative cases.
