In English the name is typically rendered as “the theory of inventive problem solving “, [2] [3] and occasionally goes by the English acronym TIPS. Following Altshuller’s insight, the theory developed on a foundation of extensive research covering hundreds of thousands of inventions across many different fields to produce a theory which defines generalisable patterns in the nature of inventive altshuuller and the distinguishing characteristics of the problems that these inventions have overcome [4].

An important part of the theory has been devoted to revealing patterns of evolution and one of the objectives which has been pursued by leading practitioners of TRIZ has been the development of an algorithmic approach to the invention of new systemsand to the refinement of existing ones.

TRIZ includes a practical methodologytool sets, a knowledge baseand model-based technology for generating innovative solutions for problem solving. It is useful for problem formulation, system analysisfailure analysisand patterns of system evolution.

There is a altshuler similarity of purposes and methods with the field of pattern languagea cross discipline practice for explicitly describing and sharing holistic patterns of design. TRIZ practitioners apply all these findings in order to create and to improve products, services, and systems. TRIZ in its classical form was developed by the Soviet inventor and science fiction writer Genrich Altshuller and his associates. His job was to help with the initiation of invention proposals, to rectify and document them, and to prepare applications to the patent office.

During this time he altahuller that a problem requires an inventive solution if there is an unresolved contradiction in the sense that improving one parameter impacts negatively on another.

He later called these “technical contradictions”. His work on what later resulted in TRIZ was interrupted in by his arrest and sentencing to 25 years in the Vorkuta Gulag labor camps. The arrest was partially triggered by letters which he and Raphael Shapiro sent to Stalingenfich and newspapers about certain decisions made by the Soviet Government, which they believed were erroneous. ByAltshuller had reviewed about 40, patent abstracts in order to find out in what way the innovation had taken place and developed the concept of technical contradictions, the concept of ideality of a system, contradiction matrix, and 40 principles of invention.

In the years that followed he developed the concepts of physical contradictions, SuField analysis structural substance-field analysisstandard solutions, several laws of technical systems evolutionand numerous other theoretical and practical approaches.

Altshuller also observed clever and creative people at work: Altshuller was appointed the head of the lab by the society. From Altshuller switched his attention away from technical TRIZ, and started investigating the development of individual creativity. He also developed a version of TRIZ for children, which was trialled in various schools. Following the end of the cold warthe waves of emigrants from the former Soviet Union brought TRIZ to other countries and drew attention to it overseas.

TRIZ presents a systematic approach for understanding and defining challenging problems: One of the earliest findings of the massive research on which genrivh theory is based is that the vast majority of problems that require inventive solutions typically reflect a need to overcome a dilemma or a trade-off between two contradictory elements.

The central purpose of TRIZ-based analysis is to systematically apply the strategies and tools to find superior solutions that overcome altshhuller need for a compromise or trade-off between the two elements. By the early s two decades of research covering hundreds of thousands of patents had confirmed Altshuller’s initial insight about the patterns of inventive solutions and one of the first analytical tools was altshullet in the form of 40 inventive principles, which could account for virtually all of those patents that presented truly inventive solutions.

Following this approach the “Conceptual solution” shown in the diagram can be found by defining the contradiction which needs to be resolved and systematically considering which of the 40 principles may be applied to provide a specific solution which will overcome the “contradiction” in the problem at hand, enabling a solution that is closer to the “ultimate ideal result”. The combination of all of these concepts together — the analysis of the contradiction, the pursuit of an ideal solution and the search for one or more of the principles which will overcome the contradiction, are the sltshuller elements in a process which is designed to help the inventor to engage in the process with purposefulness and focus.

One of the tools which evolved as an extension of the 40 principles was a contradiction matrix [13] in which the contradictory elements of a problem were categorized according to a list of 39 factors which could impact on each other. The combination of each pairing of these 39 elements is set out in a matrix for example, the weight of a stationary object, the use of energy by genrjch moving object, the ease of repair etc.

Each of the 39 elements is represented down the rows and across the columns as the negatively affected element and based upon the altahuller and analysis of patents: The main objective of the contradiction matrix was to simplify the process of selecting the most appropriate Principle to resolve a specific contradiction.

It was the core of all modifications of ARIZ till But inafter introducing the concept of physical contradictions and creating SuField analysis, Altshuller realized that the contradiction matrix was comparatively an inefficient tool and stopped working on it. Beginning ARIZc contradiction matrix ceased to be the core of ARIZ and therefore was not a tool for solving inventive problems that Altshuller believed sltshuller be pursued.

Physical contradictions and separation principles as well as SuField analysis, etc. Despite this, the 40 principles of invention has remained the most popular tool taught in introductory seminars and has consistently attracted the most attention amongst the tens of thousands of individuals who visit TRIZ-focused web sites altshullfr a typical month.

ARIZ is an algorithmic approach to finding inventive solutions by identifying and resolving contradictions. This includes the “system of inventive standards solutions” which Altshuller used to replace the 40 principles and contradiction matrix, it consists of SuField modeling and the genrivh inventive standards.

A number of TRIZ-based altsguller programs have been developed whose purpose is to provide assistance to engineers and inventors in finding inventive solutions for technological problems. Some of altzhuller programs are also altshhuller to apply another TRIZ methodology whose purpose is to reveal and forecast emergency situations and to anticipate circumstances which could result in undesirable outcomes.

One of the important branches of TRIZ is focused on analysing and predicting trends of evolution in the characteristics that existing solutions are likely to develop in successive generations of a system. Altshuller has shown that at the heart of some inventive problems lie contradictions one of the basic TRIZ concepts between two or more elements, such as, “If we want more acceleration, we need a larger engine; but that will increase the cost of the car,” that is, more of something desirable also brings more of something less desirable, or less of something else also desirable.

These are called technical contradictions by Altshuller. He also defined so-called physical or inherent contradictions: More of one thing and less of the same thing may both be desired in the same system. For instance, a higher temperature may be needed to melt a compound more rapidly, but a lower temperature may be needed to achieve a homogeneous mixture. An inventive situation which challenges us to be inventive, might involve several such contradictions.

Genrich Altshuller Quotes

Conventional solutions typically “trade” one contradictory parameter for another; no special inventiveness is needed for that. Rather, the inventor would develop a creative approach for resolving the contradiction, such as inventing an engine that produces more acceleration without increasing the cost of the engine. Altshuller screened patents in order to find out what kind of contradictions were resolved or dissolved by the invention and the way this had been achieved. From this he developed a set of 40 inventive principles and later a matrix of contradictions.

Columns refer to typical undesired results. Each matrix cell points to principles that have been most frequently used in patents in order to resolve the contradiction. For instance, Dolgashev mentions the following contradiction: The matrix cell in row “accuracy of measurement” and column “complexity of control” points to several principles, among them the Copying Principle, which states, “Use a simple and inexpensive optical copy with a suitable scale instead of an object that is complex, expensive, fragile or inconvenient to operate.


Taking a high-resolution image of the machined ball. A screen with a grid might provide the required measurement. As mentioned above, Altshuller abandoned this method of defining and solving “technical” contradictions in the mid s and instead used SuField modeling and the 76 inventive standards and a number of other tools included in the algorithm for solving inventive problems, ARIZ.

Altshuller also studied the way technical systems have been developed and improved over time. From this, he discovered several trends so called Laws of Technical Systems Evolution that help engineers predict the most likely improvements that can be made to a given product.

The most important of these laws involves the ideality of a system. One more technique that is frequently used by inventors involves the analysis of substances, fields and other resources that are currently not being used and that can be found within the system or nearby.

TRIZ uses non-standard definitions for substances and fields. Altshuller developed methods to analyze resources; several of his invention principles involve the use of different substances and fields that help resolve contradictions and increase ideality of a technical system.

For instance, videotext systems used television signals to transfer data, by taking advantage of the small time segments between TV frames in the signals. SuField analysis produces a structural model of the initial technological system, exposes its characteristics, and with the help of special laws, transforms the model of the problem.

Through this transformation the structure of the solution that eliminates the shortcomings of the initial problem is revealed. SuField analysis is a special language of formulas with which it is possible to easily describe any technological system in terms of a specific structural model.

A model produced in this manner is transformed according to special laws and regularities, thereby revealing the structural solution of the problem. Starting with an atlshuller matrix of contradictions, semantic analysis, subcategories of inventive principles and lists of scientific effects, some new interactive applications are other attempts to simplify the problem formulation phase and altshulled transition from a generic problem to altshhuller whole set of specific solutions.

See the external links for details. Although TRIZ was developed from the analysis of technical systems, it has been used widely as a method for understanding and solving complex management problems.

Genich include finding additional cost savings for the legal department of a local government body: Case studies on the use of TRIZ are difficult to acquire as many companies believe TRIZ gives them a competitive advantage and genric reluctant to publicise their adoption of the method.

However some examples are available: TRIZ is now an obligatory skill set if you want to advance within Samsung”.
