Interactive Training Model of TRIZ for Mechanical Engineers in China

Abstract： Innovation is a process of taking an original idea and converting it into a business value, in which the engineers face some inventive problems which can be solved hardly by experience. TRIZ, as a new theory for companies in China, provides both conceptual and procedural knowledge for finding and solving inventive problems. Because the government plays a leading role in the diffusion of TRIZ, too many companies from different industries are waiting to be trained, but the quantity of the trainers mastering TRIZ is incompatible with that requirement. In this context, to improve the training effect, an interactive training model of TRIZ for the mechanical engineers in China is developed and the implementation in the form of training classes is carried out. The training process is divided into 6 phases as follows： selecting engineers, training stage-l, finding problems, training stage-2, finding solutions and summing up. The government, TRIZ institutions and companies to join the programs interact during the process. The government initiates and monitors a project in form of a training class of TRIZ and selects companies to join the programs. Each selected companies choose a few engineers to join the class and supervises the training result. The TRIZ institutions design the training courses and carry out training curriculum. With the beginning of the class, an effective communication channel is established by means of interview, discussion face to face, E-mail, QQ and so on. After two years training practices, the results show that innovative abilities of the engineers to join and pass the final examinations increased distinctly, and most of companies joined the training class have taken congnizance of the power of TRIZ for product innovation. This research proposes an interactive training model of TRIZ for mechanical engineers in China to expedite the knowledge diffusion of TRIZ.

Evaluating the impact of safety pictogram training on comprehension scores and knowledge retention among engineering students

Safety pictograms are essential tools for identifying workplace hazards by providing critical information about health hazard risks,fire safety,emergency evacuation,and accident prevention.Effective safety pictogram training programs are necessary to enhance workers'knowledge of these pictograms.This study evaluates the effectiveness of a safety pictogram training program on the comprehension and retention of knowledge among engineering students.A total of 262 participants were asked to predict the meaning of 22 safety pictograms regulated by International Organization for Standardization(IsO)7010 before and after a one-hour online training session.A follow-up test was administered six months later to assess long-term knowledge retention.Results showed that the average comprehension rate increased from 60.1%before training to 68.3%after training,with a retention rate of 66.0%six months after training.The study found that training positively affected comprehension of emergency and mandatory action pictograms,while lower scores were observed for warning pictograms.Statistical tests revealed a significant effect of training on comprehension levels 16 out of 22 pictograms,with an average increase in comprehension of 11.2%.Of these 16 pictograms,the comprehension level of 10 pictograms increased after training and remained at the same level six months later.However,the scores decreased slightly six months after the intervention,indicating the need for continued reinforcement or retraining.These findings have important implications for safety education and training programs,particularly in industries where safety hazards are widespread.The positive impact of training on comprehension scores highlights the ongoing need to improve safety pictogram comprehension to consistently meet standard acceptance criteria.Future training programs may need to focus on categories such as warning pictograms and fire equipment and fire action pictograms,which exhibited lower comprehension scores,to ensure better employee understanding.

The Reform Scheme of Practice-Courses Cooperation Training Pattern of Software Engineering Major of Overseas Chinese Universities

How to improve the employment of software engineering graduates, especially, how to effectively enhance the employment competitiveness of relevant overseas students in the context of "One Belt and One Road" is one of the core tasks of overseas Chinese universities. This paper proposes a reform plan for the practical training mode of school-enterprise cooperative project in the software engineering of overseas Chinese universities. The reform plan combines education concepts with practical research and development. It subdivides students and according to the characteristics of different types of students, and is carried out on campus, outside campus(in the province), and abroad(original area), which makes senior undergraduates fully understand the needs of enterprises, constantly improve their professional practice ability, and improve their competitiveness. Thus, the professional innovation and entrepreneurship ability of students is enhanced, and it also reduces the cost of employee entry.

Research on Opportunity-Driven Redesign Process to Cooperate With Training Innovative Engineers in China

Many design engineers in cross-domain industries have attended training classes of TRIZ to improve their innovative abilities in China. Most of them are successful, but others are not. So the latest target of the trainers is to improve the training process used now in industry in China and to make the engineers to understand the basic principles of TRIZ better. Based on the mass-engineer-oriented training model(MEOTM) and mechanical engineers’ design cases, a relationship between managing activities about the opportunities for innovation and the training process is set up. It is shown that the inventive problems come first from opportunity searching for engineers. A training and gate system for evaluation is developed to involve the managing activities of the companies in the training process. Then comparison between the general analogous process and the application of TRIZ is made, which shows the advantages and depth principles of TRIZ for the engineers to apply them confidently. Lastly a new process is formed in which opportunity searching, engineers training, inventive problems identifying and solving,and three redesign paths are connected seamlessly. The research proposes an opportunity-driven redesign path that cooperates the training and opportunity searching, which will be applied in future training classes to make more and more engineers to follow.

Exploring Taiwan’s China Landscape Painting Aesthetic Preferences Through Evaluation Grid Method and the Continuous Fuzzy Kano Model

The primary objective of this study is to apply the Evaluation Grid Method(EGM)and the continuous fuzzy Kano quality model to explore the cognitive preferences of Taiwan China residents regarding the beauty of Taiwan’s China landscape paintings.The aim is to contribute to the development of social and cultural art and promote the widespread appeal of art products.Through a literature review,consultations with aesthetic experts,and the application of Miryoku Engineering’s EGM,this paper consolidates the factors that contribute to the attractiveness of painting art products among Taiwan China residents,taking into account various aesthetic qualities.Simultaneously,the paper introduces the use of the triangular fuzzy golden ratio scale semantics,specifically the equal-ratio aesthetic scale semantics,as a replacement for the traditional subjective consciousness model.Departing from the traditional discrete Kano model that employs the mode as the standard for evaluating quality,this study applies triangular fuzzy numbers to the continuous Kano quality model to analyze the diverse preferences and evaluation standards of the public.The hope is that this research methodology will not only deepen Taiwan China residents’understanding and aesthetic literacy of painting art but also serve as a reference for the popularization of art products.
