• 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: Technical System

Anything that performs a function is technical system.

Product and process system

Hierarchy of systems

Technical system Sub systems

e.g Aircraft

Minimum two elements Interaction

Like Biological systems

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 1:

• A simple improvement of a technical system

• Requires knowledge available within a trade system

Level 2:

• An Invention that includes a solution to a technical contradictions

• Requires knowledge available within an Industry

Level 3:

• An Invention that includes a solution to a physical contradictions

• Requires knowledge from other Industry

Level 4:

•A breakthrough

technology is developed

•Requires knowledge from different field of science

Level 5:

• Discovery of new phenomena

• Requires knowledge that can push the existing technology to a higher level

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 A Technical system has several characteristics

Weight, Size, color, stiffness, speed…

Contraction occur when we try to improve

Look for Trade off or optimal solution

Contractions are great opportunity to innovate

You are an engineer who is in charge of designing the radiator for a new automobile. The new design specification requires you to reduce the coolant temperature without increasing the size of the radiator. There is a technical contradiction. In conventional radiators, reducing the coolant temperature will require an increase the radiator volume since need more fin area is need for heat removal. Improving Feature: coolant temperature Degraded Feature: radiator volume The Challenge: Find an Innovative Solution to this Contradiction

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

• 8 Evolution trends

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)

7. Uneven development of parts (Heterogeneity)

8. Replacement of human (Automation)

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

What happens when the trend hits the end of the prediction?

1) A totally new discovery has to emerge, or,

2) The need for the system disappears

Trend : Object Segmentation

• 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’
