Innovate with TRIZ: Contradiction Analysis
Innovate with TRIZ: Contradiction Analysis Day 1: Introductory Concepts, TRIZ, and Technical Contradictions
- Introduction and Course Overview. Genrich Altshuller and his “theory of inventive problem solving”, TRIZ (Teoriza Rezhinija Izobretatalskih Zadach).
- Innovation Tools and Application Roadmap. The solution generation roadmap (moving between the real world and abstraction). Levels of invention. Ideality. The 40 inventive principles. Select principles in detail. Introduction to Trends of Engineering System Evolution (TESE). Case studies of product and system evolution.
- Group activity: System advancement exercise.
- Contradiction Identification. The nature of the creativity challenge. Identifying inventive contradictions.
- Group activity: Technical contradiction statement identification and development.
- Resolving Technical Contradictions. The Contradiction Matrix. Using the Contradiction Matrix to resolve conflicting requirements. Finding the right contradiction. Assigning the contradiction’s improving and worsening parameters. Identifying the associated inventive principles. Using inventive principles to focus on historically effective solution concepts.
- Group Activity: Solving technical contradictions.
- Creativity Activity 1. System Innovation Exercise: Portable coffee maker, bicycle rack/stand, better computer mouse, clothes dryer, low flow toilet (or other participant choices). Using TRIZ, the contradiction matrix, and inventive principles to design an improved system.
- Creativity Activity 2. In-House Creativity Activity. Applications of the contradiction matrix to your organization’s own innovation challenges. (Note: Participants should have a focus area or system challenge identified prior to the class.)
Innovate with TRIZ: Contradiction Analysis Day 2: Physical Contradiction Resolution
- Physical Contradictions. What they are; how they relate to, but are different than, technical contradictions. Higher level of abstractions. Defining physical contradictions. Physical contradiction resolution algorithm introduction (separation in space, time, condition and system level).
- Separating Contradictory Requirements in Space. Principles for resolving contradictory requirements in space. Application example.
- Separating Contradictory Requirements in Time. Principles for resolving contradictory requirements in time. Application example.
- Separating Contradictory Requirements in Relation or upon Condition. Principles for resolving contradictory requirements in relation or upon condition. Application example.
- Separating Contradictory Requirements at the System Level. Principles for resolving contradictory requirements at the system level. Application example.
- Group Activity: Physical contradiction resolution creativity exercises. Testing for and solving contradictions in space, time, condition, and at system-level.
- Creativity Activity 3. Innovate design changes to address contradictory system requirements by use of technical and physical contradiction analyses methods.
- Course Wrap-Up. Course review. Questions and answers. Topics for further study. Plans for future actions. Course critique.
