TRIZ is a knowledge-based method.
(1)TRIZ is the knowledge of inventing heuristic methods to solve problems. This knowledge is abstracted from patents all over the world, and triz only has books related to TRIZ.
Adopt some objective heuristic methods based on product evolution trend; (2)TRIZ has applied a lot of effect knowledge in natural science and engineering; (3)TRIZ applies the knowledge of the problem domain. This knowledge includes technology itself, similar or opposite technology or process, environment, development and evolution; (4)TRIZ is a people-oriented method, that is, the heuristic method of TRIZ is oriented to designers, not machines. TRIZ theory itself is based on the practice of dividing the system into subsystems and distinguishing useful and harmful functions. These decompositions depend on the problem and environment, and are random. Computer software only plays an auxiliary role and cannot completely replace designers. It is necessary to provide designers with methods and tools to deal with these random problems.
TRIZ is a systematic method.
(1) In TRIZ, a general and detailed model is used to analyze problems, and systematic knowledge of problems in this model is very important. (2) Systematize the problem-solving process in order to apply the existing knowledge.
TRIZ is the theory of inventing and solving problems.
(1) In order to get an innovative solution, it is necessary to solve the conflict in the design, but some steps to solve the conflict are unknown; (2) Unknown solutions can often be replaced by imaginary ideal solutions; (3) Generally, the ideal solution can be obtained through the resources of the environment or the system itself; (4) Usually the ideal solution can be inferred from the known evolution trend of the system. Triz smooth point is interpreted as:
"Innovation" (invention that promotes scientific and technological innovation)
TRIZ was first proposed by Russian scholar G.S.Altshuller (also translated by Genrich Archischuller) and his colleagues in 1946. At first, 40,000 of the 200,000 patents were taken out as the most effective solutions to various invention problems. From these most effective solutions, they abstract the basic methods of TRIZ to solve invention problems, which can be widely applied to new invention problems and help people get the most effective solutions of these invention problems. At present, more than 2.5 million outstanding patents have been studied internationally, which greatly enriched the theory and method system of TRIZ. Some companies have established computer-aided innovation systems based on TRIZ and patent database, which makes the automation of invention and innovation dawn. However, TRIZ is more of an idea or method, and people should master it through a lot of practice. Computers can't completely replace the role of people. Alikh Schulier began to establish TRIZ theory in 1946, and one of the important theories is the evolution theory of technological system. There are eight evolutionary rules in this theory, which can be used to solve difficult problems, predict technical systems and generate and strengthen creative problem-solving tools. These eight laws are: 1) the evolution law of S-curve of technical system; 2) Perfecting the ideal degree rule; 3) the law of unbalanced evolution of subsystems; 4) Evolution law of dynamics and controllability; 5) the rule of increasing the integral first and then simplifying it; 6) Evolution law of subsystem coordination; 7) Laws applied to micro-level and growth field; 8) The evolutionary law of reducing human intervention. In the past 50 years, Alikh Schulier and his TRIZ Institute have put forward various tools of TRIZ series, such as conflict matrix, 76 standard solution, ARIZ, AFD, material field analysis, DE, eight evolutionary types, scientific effects, etc. The commonly used methods are the macro-based contradiction matrix method (conflict matrix method) and the micro-based object field transformation method. In fact, TRIZ has a relatively perfect theory on the relationship between input and output (effect), conflict and technological evolution. Contradictions (conflicts) generally exist in the design of various products. According to the compromise method in traditional design, the conflict is not completely solved, but a compromise solution is obtained on both sides of the conflict, or the degree of conflict is reduced. According to TRIZ theory, the symbol of product innovation is to solve or eliminate conflicts in design and produce new competitive solutions. Designers' continuous discovery and resolution of conflicts in the design process is the driving force to promote product evolution. Technical conflict means that an action leads to useful and harmful results, and it can also mean that introducing useful effects or eliminating harmful effects leads to the deterioration of one or several systems or subsystems. Technical conflict is often manifested as the conflict between two subsystems in a system. Conflicts in reality are so diverse that a stable solution cannot be established without summarizing them. TRIZ theory induces 39 conflicts in the description of general engineering parameters (at present, the latest theory has expanded engineering parameters to 48, and put forward commercial parameters ***3 1). In practical application, at least two of the 39 engineering parameters should be used to express the internal performance of the two parties that make up the conflict, and then the conflict matrix should be found to solve the triz-related lectures.
The principle of invention. TRIZ's invention principle is the general experience gained by specialized researchers in analyzing and summarizing the existing innovation achievements in different fields, which has important reference value for guiding innovation in various fields. At present, there are 40 commonly used principles of invention. Practice has proved that these principles play an important guiding role in the invention and creation of designers. When some inventive principles are discovered, specific solutions can be considered according to these inventive principles. When solving problems, we should pay attention to using all the principles we have found as much as possible and don't refuse to adopt any recommended principles. If all possible principles do not meet the requirements, then the conflict should be redefined and re-resolved.
practical application
Through the simple application of goldfish method, let us know the application of creative problem analysis method in TRIZ theory in solving practical problems. The flying magic carpet in Egyptian mythology has caused us countless reverie. Now we might as well analyze this flying magic carpet step by step. Although there are blankets in real life, they can't fly, because of the gravity of the earth, blankets have weight, and blankets are heavier than air. So under what conditions can the blanket fly? We can exert upward force, or make the weight of the blanket less than the weight of air, or hope that gravity from the earth does not exist. If we analyze the blanket and its surrounding environment, we will find some available resources, such as neutrino flow in the air, airflow, earth's magnetic field, earth's gravity field, sunlight and so on. And the blanket itself also includes its fiber material, shape, quality and so on. Then we can use these resources to find some ways to make the blanket fly. For example, the interaction between the fibers of the blanket and neutrinos can make the blanket fly, and an engine providing reverse force is installed on the blanket. The blanket is suspended in a space without gravity from the earth due to the increase of pressure below (air cushion blanket), using the principle of magnetic levitation, or the blanket is lighter than air. Some of these methods are more realistic, but some still seem impossible. For example, even if a blanket is light, it is heavier than air. We can continue to analyze this point. For example, blankets are heavy because their materials are heavier than air triz-related lectures.
The solution is to use materials lighter than air to make blankets, or blankets as big as dust particles in the air, and so on. Through the above simple analysis process, we will find that the flying carpet in myths and legends is gradually coming to reality, from which we may get many interesting and even very useful ideas. This simple application shows the creative problem analysis principle of goldfish method: first, it separates the realistic part from the fantasy idea, and for the unrealistic part, it turns some ideas into reality by introducing other resources, and then it continues to analyze the unrealistic part until all of them become reality. Therefore, through this iterative method, practical solutions can often be brought to seemingly impossible problems. It can be seen that these creative thinking methods in TRIZ theory can effectively break our mindset, expand our innovative thinking ability, and provide scientific problem analysis methods to ensure that we seek innovative solutions to problems in a reasonable way. CBT/NOVA, an innovation ability expansion platform launched by Yi Weixun (China) Technology Co., Ltd., has discussed these creative thinking methods in detail and successfully applied them to Pro/Innovator, another software product of the company. Through the guidance of this software, the system analysis of problems can be completed quickly, and the efficiency and quality of solving problems can be greatly improved.
