4. TRIZ – Innovative Problem Solving
• TRIZ is a Russian acronym
• Originated in 1948 by Genrich Altshuller
• Analyzed 2 million + patents worldwide
• Identified 5 Levels of Innovative Solutions
• 8 Laws of Development of Solutions
• Created systematic, structured method Altshuller
1928 - 1998
7. Levels of Innovation
Level 2: • Improvement of existing system
Improvement • Methods from same industry
Level 1: • Solution by well‐known methods
Standard
8. Levels of Innovation
Level 3: • Essential improvement of existing system
Within Paradigm • Methods from other fields used
Level 2: • Improvement of existing system
Improvement • Methods from same industry
Level 1: • Solution by well‐known methods
Standard
9. Levels of Innovation
Level 4: • Creating new generation of a system
Outside Paradigm • Solution from science - not technology
Level 3: • Essential improvement of existing system
Within Paradigm • Methods from other fields used
Level 2: • Improvement of existing system

10. Levels of Innovation
Level 5: • Pioneering an essentially new system
Discovery • Usually based on major discovery, new science
Level 4: • Creating new generation of a system
Outside Paradigm • Solution from science ‐ not technology
Level 3: • Essential improvement of existing system

11. TRIZ Foundations
• Problems & solutions repeated across
industries & sciences
• Patterns of technical evolution repeated
across industries & sciences
• Innovations used scientific effects from
outside the field of innovation
12. TRIZ Defined
The practice of TRIZ consists of:
1. Learning
A. Repeating pattern of problems
B. Solutions
C. Patterns of technical evolution
D. Methods of using scientific effects
2. Applying the patterns to the specific
situation
13. Current Common Techniques
• 8‐D Problem Solving • Market Research
• Reliability Studies • Robust Design
• Trial & Error • 6 Thinking Hats
• 5 Whys (TPS) • Brainstorming
• Quality Function Deployment (QFD)

22. TRIZ Problem Solving Process
Analyze the
Problem
What to
Try?
Principles Prediction Effects
YES Solution cause
problems?
NO
Implement
23. Analyze the Problem
• Functional Analysis of:
– System
– Sub‐system
– Components
• Ideal Final Result
Ideality = ΣBenefits / (ΣCosts + ΣHarm)
• Resources
• Locate Zones of Conflict
• Etc.
24. Operators, Principles, Conditions
• Laws of Development of Engineered
Systems
• Levels of Abstraction
• Substance Field Theory (Su‐Field Theory)
• Separation Principles
• System of Standard Solutions
25. Anticipatory Failure Determination
• Creation of Failure Scenarios
• Asks how will a failure happen?
• Identifies conditions/resources necessary
for failure
• Uncovers complex causes
• Operates from “How can we produce
failure?” basis

26. IWB – Innovation Work Bench
• Uses the TRIZ Principles
• Shortens the algorithms
• Promotes quicker user involvement
• Promotes more frequent & often use
