TRIZ, the theory of inventive problem solving, is widely used not only in traditional engineering fields such as mechanical, electrical, and electronic engineering but also in IT field and generated good results. Therefore, recently many universities have opened TRIZ as a regular course. Especially, 40 inventive principles of TRIZ are not only creative thinking tools that beginners can learn relatively easily but also very effective problem solving tools, but it is not that easy to utilize it properly for solving real problems as you think. In order to use inventive principles as powerful tools for creative problem solving, it is important to educate learners to use it repeatedly through stimulating their interest about the inventive principles. So, in this paper, we introduce various inventive principles hidden in the cards that can be easily accessible in everyday life, and propose how to educate learners to evoke their interest in the inventive principles through making cards by utilizing the inventive principles.

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.

A feeding system is a key component in manufacturing packing boxes such as printing, slotting and gluing. The role of the feeding system is to feed corrugate cardboards which is usually tick and large. So, a special method is necessary to feed corrugate cardboards. This paper suggests a concept and an automatic feeding machine to feed corrugated cardboards using TRIZ, the theory of inventive problem solving. The automatic feeding machine consists of units to regulate the machine according to length and width of corrugated cardboards, a feeding part with a plurality of small rollers, and a sucking part which intensify frictional force between rollers and the lowest feeding cardboard. In particular, the feeding part is composed of an up-and-down motion plate with holes to suck the lowest corrugated cardboard as well as small rolling rollers after stopping in a moment. Thus this machine does not sensitive to size of corrugated cardboards and also can keep feeding accuracy during feeding fast.

Purpose: Storage furniture in a laboratory where chemical experiments are conducted should satisfy both the chemical reactivity and stability required in the experimental environment, commonality with general households, and economic feasibility for the mass production system. Therefore, the development of storage furniture used in the laboratory should be done quickly through a process verified by utilizing various ideas and using a method suitable for the special environment called the laboratory. This study deals with the process of developing materials for inner drawers of laboratory furniture that meet these requirements. Methods: TRIZ methodology and ARIZ-85C process were applied to satisfy the requirements arising from the product development process, ARIZ process was applied step by step to resolve the contradictions that occurred during the development process, and 40 invention principles and ideal solutions (Ideal Final Results: IFR) were derived through clear analysis of the problem to select materials suitable for the special environment of the laboratory. Results: This study focused on the selection of materials that meet the durability and chemical stability required in the special environment of laboratory furniture. Through this, various solutions were sought with the aim of reducing cost and increasing productivity, and the process of maximizing useful functions and minimizing irrational parts in use was focused on TRIZ's contradiction resolution method. As a result, we found a way to improve the performance and efficiency of laboratory furniture through the selection of optimized furniture materials and problem solving methods. Conclusion: In this study, a methodology for the development of efficient and safe laboratory furniture materials was found and verified. In the use of furniture products in a laboratory, corrosion or damage caused by chemical generators may occur, making it difficult to use as a product. As a result, a method to reduce cost and increase productivity while maintaining the durability and chemical stability of laboratory furniture was found, and by finding a solution to the two relationships between chemical safety and production efficiency in the process of selecting materials for optimized furniture materials, and applying the ARIZ development process, the effectiveness of the product development process in a special environment could be verified.

The purposes of this study are to examine the effects of learning, which was applied TRIZ's 40 inventive principles, on the improvement of learners' creativity and to offer basic information that would be necessary to study on Inventive Education in Technology Education. In order to achieve the purposes, objects were divided into two groups, experiment group(74 students) and control group(67 students), who were from B Middle school in Daejeon. Creativity Self-Assessment and Student Inventive Rating Scale were used as tools for research so that we could find the homogeneity in two groups. An applied design method was nonequivalent control group pretest-posttest design. This study was performed for 2 hours on the 1st and the 3rd Saturday in every month from the 3rd week of March, 2006 to the 3rd of July of 2006, and total researching period was 9 weeks. In that time, the students were required to learn 40 inventive principles. The results from this study are as below. (1) Applying TRIZ's 40 inventive principles had a positive effect on students' CQ(creative quotient), as influencing on the subordinate factors of creativity, such as, originality, germinal, trasformational, value, attraction, expressive power and organic systemicity. However it didn't have any effect on adequateness, properness, merit, complex and elegance. (2) Applying TRIZ's 40 inventive principles had a significant effect neither on CQ by sex, nor on the subordinate factors of creativity, except for originality and expressive power. Based on the results of the experiment, below suggestions were made to promote the application of TRIZ's 40 inventive principles to Technology Education. (1) Although this study was performed by using development activities, it is necessary to study more systemically to apply 40 inventive principles to regular subject in Technology Education. (2) As creativity was very important in Technology Education, there should be studies on the various types of inventive principles and techniques for Inventive Education in Technology Education.
