TRIZ
• TRIZ (pronounced TREEZ)
• Теория решения изобретательских задач
• (Teoriya Resheniya Izobretatelskikh Zadatch)
• Theory of Inventive Problem Solving
• Russian engineer and scientist Genrikh Altshuller
• 1946

• “The evolution of all technical systems is governed by
objective laws”
• ”Inventiveness and creativity can be learned”

Principal TRIZ Findings
1) Solutions come from a small number
of inventive principles or patterns or trends

2) All technology evolution trends
are predictable

3) Major innovations emerge from
outside the industry sector in which
they are to be deployed


Systematic Innovation


TRIZ
• A systematic approach to innovative problem solving

• The TRIZ Foundations
1. Technical systems
2. Levels of innovation
3. Law of ideality
4. Contradictions
5. Evolution of Technical Systems

• Main Tools of TRIZ
• 40 Principles, Standard and ARIZ

• When Is TRIZ Used?
• Innovative Problem Solving
• To Solve Contradictions
• Forecasting future trends


TRIZ foundation 1: Anything that performs a function
is technical system.

TRIZ foundation 2:
Level of Innovation
• 5 Levels based type and knowledge
• 77% are level 1 or 2
• TRIZ can help up to level 4 Level 5:

TRIZ foundation 3:
Law of Ideality
The law of ideality states that any technical system throughout its lifetime, tends
to become more realiable, simple, effective – more ideal.

Improvement in the system to lower cost, size, energy, etc.

Ideality -> Maximum utilization of existing resources.

A: Increase the amount of functions of the system (PC)
B: Transfer as many functions as possible (Crimping tool)
C: Transfer some function of the system to a super system (Renewable energy)
D: Utilize the available and existing resources (IPhone antenna)

Degree of ideality = (Positive Effects - Negative effects ) / Cost


TRIZ foundation 4:
Contradictions
You are an engineer who is in charge of
A Technical system has several designing the radiator for a new automobile.
characteristics The new design specification requires you to
Weight, Size, color, stiffness, reduce the coolant temperature without
increasing the size of the radiator.
speed… There is a technical contradiction.
In conventional radiators, reducing the coolant
temperature will require an increase the
Contraction occur when we try to radiator volume since need more fin area is
improve need for heat removal.
Improving Feature: coolant temperature
Degraded Feature: radiator volume
Look for Trade off or optimal solution The Challenge: Find an Innovative Solution to
this Contradiction

Contractions are great opportunity to
innovate


TRIZ foundation 5:
Evolution of Technical systems
• Technical evolution is predictable
• 8 Evolution trends
Engineering

1. Life cycle (Product)
2. Dynamization (Rigid to flexible)
3. Multiplication cycle (Single to multiple systems)
4. Macro to micro level (Shrinking size)
5. Synchronization (Homogenization)
6. Scaling up or down (Length and time scale) Business/
7. Uneven development of parts (Heterogeneity) Commercial
8. Replacement of human (Automation)
New opportunities
Limits of existing systems
Maximisation of R&D benefit

Technology Evolution Trends In The
Bigger Business Picture
• The Total Business Environment
• Macro market trends
• Commercial considerations
• (cost of change)
• (cost of development)
• (time to market)
• (risk issues)
• Competitor considerations
• Political considerations
• etc

• The Predictable Part

• Technology Trends
• Individual Evolution Trends
• Integration of trends
• System hierarchy effects

S-Curve Families
• Every single component in the system has its own family
of s-curves

• Every component’s manufacture process has its own
family of s-curves

• At the lower hierarchy levels, the more likely it is that
the designer will design at the top right hand end of the
family

Evolution Toward The Micro-level
And Increased Use Of Fields
• Technological systems tend to transition from macro systems to micro
systems. During this transition, different types of energy fields are used to
achieve better performance or control

• Example: Cooking oven development
– a. Large cast iron wood stove
– b. Smaller stove fired by natural gas
– c. Electrically-heated oven
– d. Microwave oven

• “Sometimes a system starts off simple and then
becomes more complex and then becomes simple once
again. This can be a normal process of evolution and
adaptation to change. If the ‘complex’ phase is
disallowed, then that system may be unable to evolve
or adapt.”
Edward DeBono ‘Simplicity’

Where and how to use TRIZ
1. To solve a specific problem, which is formulated as a
negative or undesired effect (part breaks, projects
fails, sales drop …).
2. To explore a business or technological bottlenecks
3. To analyze evolutionary potential of technological or
a business system and propose next generations of
the system.
4. To predict potential failures in new products and
processes and help with their prevention.
