TRIZ

TRIZ (/ˈtriːz/; Russian: теория решения изобретательских задач, teoriya resheniya izobretatelskikh zadach, lit. "theory of inventive problem solving") is “the next evolutionary step in creating an organized and systematic approach to problem solving. The development and improvement of products and technologies according to TRIZ are guided by the objective Laws of Engineering System Evolution. TRIZ Problem Solving Tools and Methods are based on them.”[1] In another description, TRIZ is "a problem-solving, analysis and forecasting tool derived from the study of patterns of invention in the global patent literature".[2] It was developed by the Soviet inventor and science-fiction author Genrich Altshuller (1926-1998) and his colleagues, beginning in 1946. In English the name is typically rendered as the theory of inventive problem solving,[3][4] 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 generalizable patterns in the nature of inventive solutions and the distinguishing characteristics of the problems that these inventions have overcome.[5]

The research has produced three primary findings:

  1. Problems and solutions are repeated across industries and sciences
  2. Patterns of technical evolution are also repeated across industries and sciences
  3. The innovations used scientific effects outside the field in which they were developed

TRIZ practitioners apply all these findings in order to create and to improve products, services, and systems.[6]

History

TRIZ in its classical form was developed by the Soviet inventor and science fiction writer Genrich Altshuller and his associates. He started developing TRIZ in 1946 while working in the "Inventions Inspection" department of the Caspian Sea flotilla of the Soviet Navy. 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 realized 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 1950 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 Stalin, ministers and newspapers about certain decisions made by the Soviet Government, which they believed were erroneous.[7] Altshuller and Shapiro were freed during the Khrushchev Thaw following Stalin's death in 1953 [8] and returned to Baku.

The first paper on TRIZ titled "On the psychology of inventive creation" was published in 1956 in "Issues in Psychology" (Voprosi Psichologii) journal.[9]

Altshuller also observed clever and creative people at work: he uncovered patterns in their thinking, and developed thinking tools and techniques to model this "talented thinking". These tools include Smart Little People[10] and Thinking in Time and Scale (or the Screens of Talented Thought).[11]

From 1986 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 trialed in various schools.[12] In 1989 the TRIZ Association was formed, with Altshuller chosen as president.

Following the end of the Cold War, the waves of emigrants from the former Soviet Union brought TRIZ to other countries and drew attention to it overseas.[13] In 1995 the Altshuller Institute for TRIZ Studies was established in Boston, USA.

Basic principles

Contradictions Matrix
40 principles of TRIZ method rendered schematically

One of the tools which evolved as an extension of the 40 principles was a contradiction matrix.[14]

French-English TRIZ principles and English Contradiction Matrix

Basic terms
  • Ideal final result (IFR) - the ultimate idealistic solution of a problem when the desired result is achieved by itself.[15]

Inventive principles and the matrix of contradictions

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.[14]

Use of TRIZ on Management Problems

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. Examples include finding additional cost savings for the legal department of a local government body: the inventive solution generated was to generate additional revenue [insert reference to cost-cutting in local government case study]. The results of the TRIZ work are expected to generate £1.7 m in profit in the first 5 years.[16]

Use of TRIZ methods in industry

Case studies on the use of TRIZ are difficult to acquire as many companies believe TRIZ gives them a competitive advantage and are reluctant to publicise their adoption of the method. However some examples are available: Samsung is the most famous success story, and has invested heavily in embedding TRIZ use throughout the company, right up to and including the CEO; "In 2003 TRIZ led to 50 new patents for Samsung and in 2004 one project alone, a DVD pick-up innovation, saved Samsung over $100 million. TRIZ is now an obligatory skill set if you want to advance within Samsung".[17]

Rolls-Royce, BAE Systems and GE are all documented users of TRIZ;[18] Mars has documented how applying TRIZ led to a new patent for chocolate packaging.[19]

TRIZ has also been used successfully by Leafield Engineering, Smart Stabilizer Systems and Buro Happold to solve problems and generate new patents.[20]

Various promoters of TRIZ reported that car companies Rolls-Royce,[21] Ford, and Daimler-Chrysler, Johnson & Johnson, aeronautics companies Boeing, NASA, technology companies Hewlett-Packard, Motorola, General Electric, Xerox, IBM, LG, Samsung, Intel, Procter & Gamble, Expedia and Kodak have used TRIZ methods in some projects.[8][22][23][24]

European TRIZ Association

The European TRIZ Association is a nonprofit association;[25] based in Germany, founded in 2000.[26] it holds conferences with associated publications.[27]

TOP-TRIZ (a modern version of further developed and integrated TRIZ methods.) “TOP-TRIZ includes further development of problem formulation and problem modeling, development of Standard Solutions into Standard Techniques, further development of ARIZ and Technology Forecasting. TOP-TRIZ has integrated its methods into a universal and user-friendly system for innovation.” [28]
  4. In 1992, several TRIZ practitioners fleeing the collapsing Soviet Union relocated and formed a company named Ideation International, Inc.[29] Under the Ideation banner, they continued to develop their version of TRIZ and named it I-TRIZ. I-TRIZ consists of four methodologies: Inventive Problem Solving (IPS), Anticipatory Failure Determination (AFD), Intellectual Property (IP), and Directed Evolution (DE) as well as a knowledge-base of over 400 "operators" where each operator is an innovative concept gleaned from the study of international patents stemming from Altshuller's original work.
