Understanding TRIZ with case study

TRIZ (Theory of Inventive Problem Solving) is a problem-solving methodology that aims to assist individuals and organizations in generating innovative solutions to complex problems. It was developed by Genrich Altshuller, a Russian engineer and inventor, in the mid-20th century.

TRIZ is based on the idea that there are universal principles that can be applied to solve technical problems effectively. These principles are derived from the analysis of thousands of patents and inventions across various industries and domains. By understanding and applying these principles, TRIZ helps to overcome psychological inertia and find inventive solutions.

The key concept in TRIZ is the identification of contradictions. Contradictions occur when a system or product needs to satisfy two conflicting requirements or functions. TRIZ provides a set of tools and techniques to resolve these contradictions and generate innovative solutions. Some of the commonly used TRIZ tools include:

Contradiction Matrix: This matrix helps identify inventive principles that have been successful in resolving similar contradictions in the past. It provides a systematic approach for selecting appropriate principles based on the specific problem.

Inventive Principles: TRIZ defines 40 inventive principles that have proven effective in solving technical contradictions. These principles serve as a catalog of strategies that can be applied to overcome conflicts and find innovative solutions.

Su-Field Analysis: Su-Field analysis focuses on the relationships between the components of a system and helps identify opportunities for improvement. It helps to break down the problem into different elements, analyze their interactions, and generate new ideas for resolving contradictions.

Ideality: Ideality is a concept in TRIZ that aims to maximize the value of a system while minimizing its drawbacks and costs. It encourages the search for ideal solutions that deliver the desired functions without any negative side effects.

Overall, TRIZ provides a systematic approach to problem-solving by leveraging the knowledge and experience accumulated from past inventions. It encourages thinking outside the box, challenging assumptions, and finding creative solutions to complex problems. TRIZ has been widely adopted by companies and organizations across various industries to enhance their innovation processes.

Here’s a case study illustrating the application of TRIZ:

Case Study: Improving Wind Turbine Efficiency

Problem: A renewable energy company is facing a challenge in improving the efficiency of their wind turbines. They want to increase the energy output while minimizing maintenance and operational costs.

Application of TRIZ:

Define the problem: The company identifies the main problem as the contradiction between increasing energy output and minimizing costs.

Contradiction Matrix: The company refers to the TRIZ Contradiction Matrix to identify relevant inventive principles. They find the contradiction “Increase the degree of automation vs. Reduce the number of operations” to be applicable to their case.

Inventive Principles: Using the identified contradiction, the company explores inventive principles related to automation and reduction of operations. They focus on Principle #6: Universality and Principle #12: Equipotentiality.

Su-Field Analysis: The company performs a Su-Field analysis to understand the system better. They break down the wind turbine into various components, such as blades, generator, gearbox, and control system.

Ideality: The company aims to maximize the ideality of the wind turbine by identifying opportunities for improvement. They brainstorm ideas to enhance the efficiency of each component while reducing the associated drawbacks.

Solution: Based on the TRIZ principles and analysis, the company comes up with several innovative ideas:

  • Implementing universal components that can adapt to different wind conditions (Principle #6: Universality).
  • Designing a system with equipotential surfaces to minimize energy losses (Principle #12: Equipotentiality).
  • Introducing an intelligent control system that optimizes turbine performance based on real-time wind data.
  • Using advanced materials for the turbine blades to reduce weight and increase energy capture.
  • Evaluation and Implementation: The company evaluates the feasibility and potential benefits of each solution. They conduct simulations, prototype testing, and cost analyses to select the most promising ideas. Once validated, they proceed with implementing the chosen improvements into their wind turbine design and operations.

Results: The company successfully implements the TRIZ-inspired solutions, resulting in significant improvements in wind turbine efficiency. The energy output of the turbines increases, while maintenance and operational costs decrease. The company gains a competitive advantage in the renewable energy market and contributes to a more sustainable future.

This case study demonstrates how TRIZ can guide problem-solving efforts by providing a structured framework and inventive principles. By applying TRIZ tools and techniques, the company was able to generate innovative ideas and overcome the contradictions they faced, leading to tangible improvements in their wind turbine technology.
