TRIZ — Wikipedia Article (fetched 2026-06-11)

TRIZ (pronounced /trɪz/) is a Russian acronym for teoriya resheniya izobretatelskikh zadach, meaning "theory of inventive problem solving." It's a methodology that merges "an organized, systematic method of problem-solving with analysis and forecasting techniques" drawn from studying global patent literature. The approach is guided by the laws of technical systems evolution.

Three Core Findings from Patent Research

The analysis of hundreds of thousands of inventions produced three key insights:

Problems and solutions recur across different industries and sciences
Patterns of technical evolution repeat across industries and sciences
Innovations often rely on scientific effects from outside the field where they were developed

History

Genrich Altshuller (Creator)

Genrich Altshuller, a Soviet inventor and science-fiction author, began developing TRIZ in 1946 while working in the inventions inspection department of the Caspian Sea flotilla of the Soviet Navy. His job involved evaluating invention proposals, refining them, and preparing patent applications. Through this work, he observed a recurring pattern: improving one parameter often worsens another—what he termed a technical contradiction.

Interruption by the Gulag

In 1950, Altshuller was arrested and sentenced to 25 years in the Vorkuta Gulag. The arrest was "partially triggered by letters that he and Refael Shapiro sent to Stalin, government ministers, and newspapers, criticising Soviet policy decisions." He was released during the Khrushchev Thaw after Stalin's death in 1953 and returned to Baku.

First Publication

The first academic paper on TRIZ, On the psychology of inventive creation, was published in 1956 in the journal Issues in Psychology.

Later Development

By observing skilled inventors, Altshuller identified recurring creative thinking patterns and developed tools including Smart Little People and Thinking in Time and Scale (also called the Screens of Talented Thought). In 1986, he shifted focus from technical problem-solving to developing individual creativity, adapting TRIZ for children, tested in several schools. After the Cold War, emigrants from the former Soviet Union spread TRIZ internationally.

Key Concepts and Tools

The 40 Principles of Invention

Altshuller screened patents to identify how contradictions were resolved, ultimately developing 40 inventive principles—a suite of ideas designed to help solve difficult technical problems. These are often applied through a structured tool called the contradiction matrix.

The Contradiction Matrix

This is "a structured and systematic representation of basic engineering parameters of objects, or systems, such as mass, length and manufacturing tolerances." Each cell in the matrix contains ordered principles identified by their order numbers, chosen based on extensive statistical studies of patents. The matrix helps users find which inventive principles have historically resolved specific pairs of conflicting parameters.

Ideal Final Result (IFR)

The IFR is "the ultimate solution of a problem when the desired result is achieved by itself."

Technical Contradictions

Altshuller proposed that every technical problem requiring a solution can be categorized by its main technical contradiction. He argued that finding solutions is facilitated by forming analogies to solutions already found for other technical problems.

Laws of Technical Systems Evolution

The evolution of any system is governed by general laws of systems evolution. These laws outline predictable trends in how technical systems develop over time.

ARIZ Algorithm

While not extensively detailed in this article, ARIZ (Algorithm for Inventive Problem Solving) is part of the TRIZ methodology. The article references "further development of ARIZ" in the context of TOP-TRIZ.

Substance-Field Analysis

The article mentions "development of Standard Solutions into Standard Techniques" as part of TOP-TRIZ, referencing the substance-field (Su-Field) analysis tradition within TRIZ. Standard Solutions were originally derived from Su-Field modeling.

Criticisms and Limitations

The article notes several limitations or points of caution:

Sections rely on citation needed tags (dated February 2026) regarding the structured contents of the contradiction matrix
Some referenced sources are marked as self-published (e.g., BAE Systems/GE use cases, Mars chocolate packaging case study)
One citation has a permanent dead link
A DOI is inactive (as of May 2026) in one reference

Modern Applications and Industry Use

Samsung

Samsung invested heavily in embedding TRIZ company-wide. "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 became "an obligatory skill set if you want to advance within Samsung."

Intel

A validated case study at Intel measured "significant productivity and profitability gain," officially verified by Intel's Finance "to exceed $212.5M in Return on Investment over the course of a 21-month deployment" across Intel's semiconductor manufacturing ecosystem.

Other Companies Using TRIZ

The article lists: BAE Systems, GE, Mars, Rolls-Royce, Ford, Daimler-Chrysler, Johnson & Johnson, Boeing, NASA, Hewlett-Packard, Motorola, General Electric, Xerox, IBM, LG, Intel, Procter & Gamble, Expedia, Kodak, plus Leafield Engineering, Smart Stabilizer Systems, and Buro Happold.

Modern Variants

TOP-TRIZ: Developed by TRIZ Master Zinovy Royzen, described as "further development of problem formulation and problem modeling, development of Standard Solutions into Standard Techniques, further development of ARIZ and Technology Forecasting." It is presented as Royzen's own version, not accepted by the International TRIZ Association (MATRIZ) as the definitive modern method.
I-TRIZ: Developed by Ideation International, formed in 1992 when several TRIZ practitioners fled the collapsing Soviet Union.
Liberating Structures' TRIZ: A facilitation method "inspired by one small element of" original TRIZ, used in a distinct context. It helps groups identify and eliminate counterproductive practices by imagining worst possible outcomes and designing preventive steps.

European TRIZ Association (ETRIA)

A German-based nonprofit founded in 2000, hosting conferences with published proceedings.

"The innovations have scientific effects outside the field in which they were developed."
Altshuller recognized that improving one parameter "often leads to the deterioration of another, a situation he termed a technical contradiction."
