Created by: Genrich Altshuller
When: 1946-Cold War Era
Where: U.S.S.R
Why:Genrich was part of
Invention Inspection division ofSoviet Navy and was imprisoned
for 6 years.

How TRIZ Invented
Genrich Altshullerreviewed 40,000patents and found a common patternbetween them
Generates ideas for overcoming thecontradiction by choosing between
multiple options
Way to eliminate engineering trade-offs

TRIZ Basics
Based on the idea that somewhere
someone else has already solved your
problem (or close to it)!
The hard part is now using their solution to
fix your own.

TRIZ Basics
Start by researching similar
products to troubleshoot your own
problemUse the patents of similar
products to compare to your own
concept

Contradictions
1. Technical Contradictions
2. Physical (Inherent) Contradictions

Technical Contradictions
Basic Engineering Trade-offs
More of one thing means less of another
Ex: Want more acceleration (improve) meansa larger engine, cost increases, weight, etc(degrades)

Physical (Inherent) Contradictions:
More of one thing and less of another may be
needed for a system (i.e. situations in which
one object or system has contradictory,
opposite requirements)
EX: Coffee should be hot (to enjoy), but cold
so as not to burn

40 Inventive Principles

Matrix of Contradictions
Composed of a 39X39 matrix
Rows: -System features you want to improve
such as Power, Speed, weight, etc
Columns: -Undesirable features matching that
of the rows
Each cell gives principles that have been
most frequently used to resolve the issue

Example 1: -
a problem is that we need a
device to hold an easily breakable
part, which has a complex shape.

Solution: -
Use Contradiction Matrix And try to
Positive effect on vertical column and
negative effect on row. you will find in
(10, 30) which narrow down your principal

Theory of Ideality
Ideality = benefits /(Cost + Harm)
Ideality is the situation after a particular
problem has been solved. This ideal
solution is termed the Ideal Final Result
(IFR) and is considered in TRIZ toensure that the right problem is solved
the first time

S-Field Theory
The Basic Ideas
In every technological system one can discern two objects or
substances, S1 and S2.
Mechanical
Acoustic
Thermal
Chemical
Electric
Magnetic

Example
Problem: - Finding Refrigerant Leaks
S1 represents the maintenance worker
S2 the leak
Field(f1) the light
(an optical field)

Solution :
Add a small amount of a fluorescentsubstance, S3, to the refrigerant, and to
look for it using ultraviolet light
