Identification and conception of cleaner production opportunities with the Theory of Inventive Problem Solving

This paper presents an introduction to the theory of inventive problem solving (TIPS); a series of powerful tools to direct the search for solutions to engineering problems. The system was developed by G.S. Altshuller and his school in the former USSR, based on an extensive study of the world patent database of over 400,000 inventions from different engineering fields. From these studies it was recognised that the evolution of technical systems follow a series of laws or trends. These laws can be utilised in the development of engineering solutions as an alternative to a `trial-and-error' or brainstorming techniques for problem solving. The tools include a set of the most commonly applied inventive principles, an algorithm for inventive problem solving, standard solutions, and a database containing hundreds of physical, chemical and geometric effects. Several examples illustrating the methods are given. (4 pages)

The article validates the possibility and efficiency of improving creative thinking ability while teaching English via the TRIZ (theory of inventive problem solving) method to international students. The objectives of the current research are (a) to investigate the lingoudidactic potential of TRIZ problem-solving method in the process of teaching English to international students, (b) to describe the algorithm of international students` creative thinking development via the TRIZ method, (c) to check the effectiveness of the devised algorithm. In our research TRIZ is considered as a set of methods for solving logical tasks, consisting of the following steps: general preparation, situation analysis, questions preparation, hypotheses generation, hypotheses selection, hypotheses testing. The ambitions behind the devised algorithm are to teach in-depth analysis of the situation, to intensify critical and logical thinking in a non-standard situation, to overcome stereotypical thinking, to stimulate teamwork and communication abilities. The methodology has been tested on the second-year international students from Peter the Great St. Petersburg Polytechnic University majoring in Public Relations in the year 2021. The methods of this research include both theoretical (assessment of the key pedagogical principles of the TRIZ Method integration and generalization of facts and concepts, data analysis) and empirical ones (methodological algorithm development, a set of experiments: educational and control, evaluation of educational outcomes). We have obtained satisfactory results demonstrating that the problem-based learning algorithm devised leads to an improvement in students’ creative thinking ability.KeywordsCreative thinkingTRIZ methodIntercultural communicationInternational studentsForeign language learningMultilingual audience

Permaculture and TRIZ – Methodologies for Cross-Pollination between Biology and Engineering

The STEM body of knowledge has become a core focus for the Ministry of Education of Malaysia to be embedded in the mainstream education curriculum but one of the challenges is to improve the level of student competency in problem-solving skills. A new policy has been developed at the governmental level to ensure the change can be successfully made and executed successfully at the school level. One of the initiatives is to enhance the complex problem-solving skills of the students by introducing the Theory of Inventive Problem Solving (TRIZ) topic in the Curriculum and Assessment Standard Document for Design and technology subject. The integration of the TRIZ is streamlined with other creativity theories and thinking models. The adoption of TRIZ is strategically designed to support and complement the student in developing a technological project and design competencies. The teaching and learning process of TRIZ in the subject has started in 2018 as the first official textbook has been used in all schools around Malaysia. A survey has been carried out to 1032 respondents that involved in the process of teaching and learning the TRIZ topic in the subject. The result has shown positive feedback from respondents, and further issues have been highlighted to improve the process of teaching and learning in school.

The present competitive market focuses on producing high-quality products with the lowest possible cost. To help accomplish this objective, various quality-enhanced tools have been put forward in recent years and, of these, process window approach (PWA) has emerged as perhaps the most viable and efficient technique for process quality improvement. The PWA is a powerful tool for quickly optimizing and confirming the quality and robustness of a process setup for any parameters. The work in this paper focuses on implementing a proposed PWA in order to optimize the sand-casting operation variables. In this research, the authors have kept their prime focus on minimizing the defects developed in the sand-casting process by PWA. Analysis of various critical process parameters and the interaction among them is carried out with the help of Taguchi method of experimental design. To optimize the results obtained and to make the analysis more precise and cost-effective, response surface methodology (RSM) is also incorporated. The optimized parameters obtained using the Taguchi method and RSM are then tested in an industrial case study. It is validated by proposed process window approach.

Innovation contests represent a type of open innovation that companies can use for gaining access to innovation ideas from different target groups. These innovation ideas have a measurable creative output and arise in an ideation process that usually takes place unconsciously among the participants, but can be traced back through operationalization with the inventive principles from the Theory of Inventive Problem Solving (TRIZ). We evaluate these two aspects—creative output and ideation process—on the basis of over 600 innovation ideas collected from more than 1200 students during eight identical courses on ‘Innovation Management’ between 2015 and 2022, using a Large Language Model (GPT‐4). We identify two important relationships between the two variables. Firstly, our data show that the more inventive principles are used in the ideation process, the higher the creative output of an innovation idea. Secondly, at least in our setting, universal inventive principles outperform technological inventive principles in terms of creative output. This study is the first to use GPT‐4 to simultaneously assess both the creative output of more than 600 innovation ideas and the hidden TRIZ inventive principles behind them.

The heat dissipation of car seat back is poor if there is no extra ventilation system. This paper applied ARIZ (Algorithm of Inventive Problem Solving) to get 6 proposals to optimize the heat dissipation of car seat back. Various TRIZ (Theory of Inventive Problem Solving) methods were used, such as Function Model, Cause and Effect Chain, Contradiction Analysis, Substance Field and SLP (smart little people) and so on. All these methods were used by a logical structured process (ARIZ) which incrementally evolves the complex problem to a point where it was simple to solve.

State of the art on the role of the Theory of Inventive Problem Solving in Sustainable Product-Service Systems: Past, Present, and Future

Supply chain challenges require not only effective management, but also a new innovative strategy to reduce costs and maximize its efficiency. Traditional problem-solving methodologies specific to the areas of supply chain management (SCM) find their limits when confronted with an inventive problem or a problem containing a contradiction. TRIZ (theory of inventive problem solving) is an effective theory for systematizing innovation and solving complex problems containing contradictions. Thus, the use of the theory TRIZ can be considered as a way to meet future challenges in SCM fields and get innovative solutions. This paper presents a method for solving supply chain problems and achieving a low-cost, based on complementarities between TRIZ and discrete event simulation and specific methods for solving supply chain problems. In the proposed model, a witness simulation model of the initial problem is developed to optimize the problem and find the system limits. Then, specific problem solving methods are applied to change the original description of problem and move towards a space in which a solution can be found. The discrete event simulation allows for experiments on the system to be created and analyzed. Thus, an experimental design was developed to establish the cause-and-effect relationships between the parameters of the system in order to formulate a generalized system of contradictions. And finally, ARIZ 85C, the most mature meta-methods of TRIZ, is used to address related contradictions for searching for an innovative solution, which must be subsequently implemented and evaluated in the discrete event simulation. The suitability of this new approach is finally proven through an industrial case study conducted in a company specialized in the manufacture of electronic devices for automobiles.

Over the centuries, the trial‐and‐error‐method (T&EM) was the main creativity tool. While resulting in an enormous amount of incredibly valuable inventions enabling human survival, T&EM became less and less acceptable as a method for design and systematic innovation with the acceleration of technological evolution. During the second part of the twentieth century, hundreds of creativity techniques were developed; however, most of them were psychologically based, were lacking a systematic approach and structure and could not provide smooth integration with normal engineering and new product development. This paper provides a brief description and comparative analysis of the best known creativity techniques including a brand new knowledge based approach to creativity implementation which is part of the theory of inventive problem solving (TRIZ) in its classical and advanced forms.
