- Genrich Altshuller, a Soviet patent examiner and engineer, began developing TRIZ in the 1940s after studying thousands of patents and identifying common patterns in innovative solutions
- Altshuller discovered that many inventive solutions involved resolving contradictions, such as improving one aspect of a system without compromising another
- He compiled his findings into a set of 40 Inventive Principles, which serve as a foundation for TRIZ problem-solving techniques
Development in the Soviet Union
- TRIZ was further developed and refined by Altshuller and his colleagues in the Soviet Union during the 1950s and 1960s
- The Soviet government recognized the potential of TRIZ for enhancing innovation and problem-solving in various industries, leading to the establishment of TRIZ research groups and training programs
- TRIZ gained popularity in the Soviet Union, particularly in the aerospace and defense sectors, where it was applied to solve complex engineering challenges
Core principles of TRIZ
- TRIZ is based on several core principles that guide the problem-solving process and help users identify innovative solutions
- These principles are derived from the analysis of successful inventions and aim to provide a systematic approach to creativity and innovation
Contradiction as a source of innovation
- TRIZ recognizes that many problems arise from contradictions, where improving one aspect of a system leads to the deterioration of another
- Altshuller identified 39 technical parameters (weight, speed, strength) and 40 Inventive Principles (segmentation, asymmetry, prior action) that can be used to resolve contradictions and generate innovative solutions
- By focusing on identifying and resolving contradictions, TRIZ helps users break free from psychological inertia and find novel solutions to problems
Ideality and system evolution
- TRIZ introduces the concept of , which refers to the ideal state of a system where all desired functions are performed without any harmful or unnecessary effects
- The pursuit of ideality drives the evolution of technical systems, as inventors strive to create solutions that maximize benefits while minimizing costs and negative consequences
- TRIZ provides tools and techniques for analyzing the current state of a system, identifying opportunities for improvement, and guiding the system towards greater ideality
Patterns of invention
- TRIZ is based on the premise that there are patterns and principles that underlie successful inventions across various fields and industries
- Altshuller identified eight patterns of evolution that describe how technical systems tend to evolve over time (increased ideality, uneven development of system parts, transition to a higher-level system)
- By understanding and applying these patterns, TRIZ users can anticipate future developments and create solutions that align with the natural evolution of technical systems
TRIZ problem-solving tools
- TRIZ offers a range of problem-solving tools and techniques that help users analyze problems, identify contradictions, and generate innovative solutions

40 Inventive Principles
- The 40 Inventive Principles are a set of strategies derived from the analysis of successful patents, which can be applied to resolve contradictions and generate innovative solutions
- Examples of Inventive Principles include segmentation (dividing an object into independent parts), asymmetry (changing the shape or properties of an object from symmetrical to asymmetrical), and prior action (performing an action before it is needed)
- TRIZ users can refer to the 40 Inventive Principles when faced with a problem or contradiction, using them as a source of inspiration for generating creative solutions
Contradiction Matrix
- The Contradiction Matrix is a tool that helps users identify the most relevant Inventive Principles for resolving a specific contradiction
- The matrix consists of 39 technical parameters (weight, speed, strength) arranged in rows and columns, with each cell containing the numbers of the Inventive Principles that have been successfully used to resolve contradictions between those parameters
- By locating the intersection of the improving and worsening parameters in the Contradiction Matrix, users can quickly identify the most promising Inventive Principles to apply to their problem
Substance-Field Analysis
- Substance-Field Analysis (SFA) is a TRIZ tool for modeling and analyzing the interactions between the components of a technical system
- SFA represents a system as a set of substances (objects or components) and fields (energy or forces) that interact with each other
- By analyzing the relationships between substances and fields, users can identify problems, inefficiencies, and opportunities for improvement in the system
- SFA provides a set of standard solutions for modifying or restructuring the substance-field model to resolve problems and enhance the system's performance
