There have been 3E problems of energy, economy and environment since the earth has its history. Especially, the energy and environment problems have been getting serious after the modem industry revolution. Therefore, the demand of gas as an eco-friendly energy source is getting increased. With the demand of gas, the installation and use of gas boiler is also increased, so human life injury by the waste gas(CO) of boiler goes on increasing every year. It is the content about a life of the exhaust tube which is used at Gas boiler in this paper. We explain also the course to apply the 6SC(6 Step Creativity)of practical TRIZ and evaluate the resolution.

This paper proposed a model of Creative Problem Solving education, using CREAX software based on TRIZ. Learners can get the motivation about development of creative thinking through the theory of TRIZ. Furthermore, they can have good command of creative problem-solving process from the software practice course. As a result of the study, the learners could realize the importance of the creativity and adaptability which are demanded from the knowledge-based society. We planned a three major course for development about adaptability of creative problem solving process and we proposed a guideline about each step of the software utilized CREAX. So, we established the courses about leaners can get the creative problem-solving skill more efficiently.

This paper represents a study on the development of the conceptual design for the Skateboard by TRIZ. At first the problems of the Skateboard of the commercial Skateboard was analyzed. And its development object was defined in connection with the Improvement direction. The developed conceptual design was compared with the registered patents and practical new devices at the Korea Industrial Property Office. The Comparison shows the developed conceptual design is on the same level with the above mentioned, and the usefulness of TRIZ methodology. The Analysis with the Motion Capture equipment shows the developed Skateboard commercial efficient than commercial one.

Traditionally engineers' main roles are concentrated on solving any given problems and engineering education has emphasized problem solving ability. Therefore engineers intend to solve easily perceived problems with their knowledge and experience instead of trying to analyze the given problems thoroughly and to define real problems, and go through lots of trial and error. So, engineers require the ability to define real problems accurately before trying to solve the problems. This study proposes a real problem definition process using visualization of a core zone and TRIZ concepts such as contradictions and IFR(Ideal Final Result) in order to define real problems with minimum trial and error. TRIZ is the theory of inventive problem solving and was developed by a Soviet engineer and researcher Genrich Altshuller from 1946. Nowadays many industries use TRIZ and its effectiveness was already proved by lots of real problem solving in various areas. Therefore TRIZ might be very effective tool for developing students' inventive thinking ability in engineering education.

An Education-Industrial cooperative system is a systematic effort that industrial body and educational body cooperate with each other in order to achieve two different purposes. This paper suggested an education-industrial cooperative system model based on the experiential learning through cooperating with the industry. SEARIM, the research activities company is received the guideline for the improvement and management of quality regarding products by using TRIZ/6-sigma. Also, we evaluated and analyzed the product of this study result based on the result a survey.

Nudge, which is recently in the spotlight again, refers to inducing a person's behavior change naturally rather than forcibly in behavioral economics. It is used not only in behavioral economics, but also in various fields such as design and communication, and is continuously expanding. Furthermore, it is used for entrepreneurship education as well as solving social problems in the public sector that are easily encountered in the surroundings. Given this aspect, it would be very meaningful to understand and analyze Nudge from the perspective of problem solving. Therefore, this study analyzed the usefulness and utility of Nudge from the perspective of problem solving. The usefulness of Nudge was confirmed through TRIZ technique, which is a representative technique for problem solving, and conversely, the utility of Nudge in TRIZ technique was also analyzed. The results of this study are expected to provide useful theoretical and practical implications for researchers and managers interested in knowledge management for problem solving.

An actuator latch device of a hard disk drive is installed for locking an actuator to hold a magnetic head parked in a parking zone. Applying an external force to the drive, the head can move away from the parking zone and destroy data on the disk. A magnet latching mechanism is used to prevent the actuator from moving when the computer is not in use. A permanent magnet holds the actuator when the head is in the parking zone. When the computer is turned on, the actuator has to overcome the latch magnet in order to move. A stronger latch magnet will hold the actuator adequately, but the actuator will not be released when unlocking is required. A breakthrough solution is needed to improve the reliability of the drive without any deterioration of its performance. In order to obtain the idea for resolving this technical contradiction, we analyse patents for actuator latch device of a hard disk drive. A practical way for solving contradictions in product development using TRIZ is proposed in this paper.

Recently, flipped learning is being highlighted especially at the college of engineering because of its self-directed learning which direction matches that of the engineering education system. Although many engineering professors have tended to apply the flipped learning to their classes, they experienced a number of significant problems and challenges in practical implementing. By using TRIZ method as a tool for creative problem solving, that have been developed and applied in many fields ranging from engineering as well as management, this study aims to solve the education dilemma between learning efficiency and learning effectiveness, create a new concept of the flipped learning based on the solutions, and then explore its educational feasibility for successfully adopting it to engineering courses. This study suggests an instructional design for implementing the flipped learning according to the characteristics of engineering classes and then designs a new model of the flipped learning according to that procedure. Also, based on the empirical results in applying a new flipped learning model to the applied mathematics, this paper proposes several guidelines for the successful application of flipped learning in the future.
