- Agile Methodology, Continuous Improvement, Creative Design Strategies, Design Thinking, Innovation, Problem Solving Techniques, Quality Management, Systems Modeling Language (SysML), TRIZ
Objective:
How it’s used:
- Involves defining a problem in terms of technical contradictions (e.g., a product needs to be stronger but also lighter), identifying relevant inventive principles (from a list of 40) or using other TRIZ tools (e.g., Substance-Field Analysis, ARIZ) to find innovative solutions.
Pros
- Provides a systematic approach to inventive problem solving; helps overcome psychological inertia and find non-obvious solutions; based on a vast knowledge base of successful inventions.
Cons
- Can have a steep learning curve; requires abstract thinking and understanding of TRIZ concepts; some tools can be complex to apply effectively.
Categories:
- Engineering, Ideation, Problem Solving, Product Design
Best for:
- Systematically solving complex technical problems and generating innovative solutions by resolving contradictions.
TRIZ is particularly advantageous in sectors such as aerospace, automotive, consumer electronics, and manufacturing, where engineering challenges often embody competing demands. This methodology is frequently applied during the design and development phases of projects, especially when teams face constraints or conflicts in performance characteristics, such as needing a product that is both more durable and cost-effective. Participants typically involve multidisciplinary teams, drawing from engineering, design, and planning disciplines to fully leverage the technique’s potential in generating creative solutions that can be patented or commercialized. By systematically identifying technical contradictions, TRIZ encourages teams to think beyond conventional boundaries and access a rich repository of inventive principles that can inspire novel approaches; these principles include strategies like segmentation, combination, and the use of negative or positive feedback. Notably, this approach not only serves to resolve immediate engineering dilemmas but also cultivates an innovative mindset that enables teams to anticipate future challenges. For instance, a recent application of TRIZ in the field of renewable energy focused on increasing the efficiency of solar panels while simultaneously decreasing production costs, exemplifying how TRIZ can be applied to push the limits of existing technology while paving the way for sustainable advancements. Many organizations have reported that utilizing TRIZ can lead to a significant reduction in time spent on problem-solving, as it provides a clear framework that facilitates creative thought processes, reducing the likelihood of falling into established thinking traps.
Key steps of this methodology
- Formulate the problem by defining technical contradictions.
- Analyze the problem using the 39 engineering parameters to identify areas of conflict.
- Identify the relevant inventive principles related to the contradictions from the 40 principles list.
- Apply the Substance-Field Analysis to model the system and its interactions.
- Utilize ARIZ (Algorithm of Inventive Problem Solving) for systematic problem solving.
- Generate innovative ideas by employing the inventive principles identified.
- Evaluate and refine potential solutions to address the contradictions effectively.
- Implement the selected solution while considering physical and operational feasibility.
Pro Tips
- Implement the 39 Engineering Parameters in a targeted way to uncover specific contradictions and their solutions, aiding in clearer problem definition.
- Utilize the "Trimming" technique within TRIZ to systematically eliminate unnecessary components without affecting functionality, increasing efficiency.
- Integrate Substance-Field Analysis early in your design process to visualize interactions and identify underlying conflict sources, which can lead to innovative concepts.
