7. TRIZ
Projects frequently reach a point where the
analysis is completed and the team is at a point
where it is unclear where they need to go for
resolution. This applies not only to projects but
to problem solving, root cause analysis, or
even Six Sigma (upon completion of the
analysis phase). The project team must be
creative in order to determine what to do next.
TRIZ minimizes the chance of unpredictable
and unrepeatable results that are associated
with brainstorming or brainwriting.
@QAI

8. TRIZ
• TRIZ is based on the idea that many of
the underlying “root” problems that
engineers face today contain elements
that have already been solved
(approximately 90%), often in a
completely different industry, for a
totally unrelated situation, that uses an
entirely different technology.
@QAI

9. TRIZ
• The most important recognition is that
“technical systems evolve”
– Which evolves towards the
increase in ideality
• By overcoming Contradictions
–Achieved primarily with the
minimal introduction of
resources
@QAI

10. T.R.I.Z. (Trez or trees)
Theoria Resheneyva Isobretatelskehuh Zadach
Theory of Inventive Problem Solving
– Developed after WWII (1946) by Genrich
Atschuller (1926-1998), a Russian inventor and
naval officer. He was sent to the Siberian Gulag
camp by Stalin for thinking too much. He was
released from prison after Stalin’s death.
– Based on a theory that there are universal
principles of inventive and creativity.
– TRIZ is structured method that can be used to
rapidly generate plausible concepts that solve
problems in technical and non-technical domains.
@QAI

11. Altschuller / T.R.I.Z.
• Started with 400,000 patients, today it
includes the study of more than 2.5 million
patients.
• Altschuller discovery:
– Each innovative patient solves a technical
problem, but across domains, there are common
solutions. These solutions were boiled down to 40
principles.
– Inventive problems often carry with them inherent
contradictions. (e.g. stronger, but heavier)
– Anyone can use this knowledge and methodology
to solve problems.
@QAI
– Resources are often idle during problem solving.

15. The Three Premises of TRIZ
• Ideality (ideal solution)
• Resolve Contradictions
• System Approach
TRIZ Approach/Tools
• Innovation Situation Questionnaire (ISQ)
• Problem formulator
• Substance-Field Analysis (Su-Field)
@QAI

16. Why TRIZ ?
• Simply stated, we need to create
innovative products and services to
remain competitive !
– We need to significantly improve the
engineers ability to quickly solve difficult and
seemingly impossible engineering problems
which often lead to next generation
“innovative” products.
Creative Problem Solving!
Provides a Dialectic Way of Thinking!

18. Example
• Generic problem solving, think in broad
terms:
– Principle #3 Local Conditions / Quality
– Airport with smoking areas
– Yard light with a photocell
– Pen with an eraser
• Combine several techniques and tools to
enhance problem solving
@QAI

19. Altschuller Contradiction to solve
• The 40 Inventive Principles can be utilized
Matrix
problems but unfortunately, fixing one problem often
results in creating another problem.
Examples:
– Companies buy other companies to grow and
strengthen themselves. This often results in a
company disorganized and less stable.
– Coffee should be hot for enjoyable drinking
but cool enough to prevent burning the
drinker.
– Bandwidth increases (Good) but requires more
power (bad)
– Training increases competence (Good) but
requires employees to be away from their job
responsibilities (bad).
• These contradictions can be resolved by applying the
Contradiction Principles in a Contradiction Matrix.
@QAI

20. Altschuller Contradiction Matrix
As you can see from the examples on
the previous slide there are two
categories of contradictions.
1. Technical contradictions are based on
classical engineering of “trade-offs.” The
desired state can not be obtain because
there is a barrier in the system.
2. Physical contradictions (Inherent) are
situations in which one object or system
contradicts the requirements of the other.
@QAI

21. Contradiction Principles
1. Weight (of object in motion) 21. Shape
2. Weight (of stationary object) 22. Stability
3. Length (of object in motion) 23. Strength
4. Length (of stationary object) 24. Power
5. Area (of object in motion) 25. Losses of energy
6. Area (of stationary object) 26. Losses of substance
7. Volume (of object in motion) 27. Losses of Information
8. Volume (of Stationary motion) 28. Losses of Time
9. Speed 29. Quantity of Substance
10. Force or Intensity 30. Reliability
11. Stress or Pressure 31. Measurement Accuracy
12. Use of Energy (of object in motion 32. Manufacturing Precision
13. Use of Energy (of stationary object) 33. Harmful external effects
14. Duration of Action (of object of motion) 34. Ease of manufacturing
15. Duration of Action (of stationary object) 35. Ease of operation
16. Temperature 36. Ease of repair
17. Illumination intensity 37. Adaptability or versatility
18. Difficulty in monitoring or measuring 38. Device complexity
19. Productivity 39. Extent of automation
20. Object generated harmful effects
@QAI

22. Contradictions
Contradictions appear first as a gap
between demands and supplies. They
are overcome by break-through
inventions. These inventions form the
micro-steps of evolution in technical
systems. Since the solutions are not
known, creative problem solving is the
method utilized to overcome
contradictions.
@QAI

23. Contradiction Matrix
• Are a result of Altschuller’s patent research
• The principles are technical characteristics
• Can be applied throughout the Six Sigma
DMADV process whenever conflicts or
contradictions arise.
• It is a large table that link pairs of the
engineering principles (39 X 39 matrix).

@QAI

25. Contradiction Matrix
The core process is to drive a physical
contradiction (using the matrix) and solve
it with the Separation Principle. Once the
physical contradiction is determined this
solution technique is powerful enough to
identify break-through (innovative)
solutions.
@QAI

26. TRIZ
TRIZ works and is used by large as
well as small organizations on several
levels to solve real, practical everyday
problems. TRIZ is utilized at
companies such as Ford, Motorola,
Proctor & Gamble, Eli Lilly, 3M, LG
and …
@QAI

27. Summary
Innovative concepts are critical
and a necessity to drive the
optimization efforts to design new
products or redesign exsisting
processes or products.
