Genrikh Saulovich Altshuller (1926- 1998)
Soviet engineer, inventor, scientist, journalist and
writer
TRIZ is a problem solving method based on logic
and data, not intuition.
Objectives of TRIZ are to define;
Generalisable patterns in the nature of inventive
solutions.
And the distinguishing characteristics of the
problems that these inventions have overcome.
It is increasingly common in
Six Sigma processes
Project management and risk management
systems.
Organizational innovation initiatives.
Somebody someplace has already solved this problem (or
one very similar to it.)
Creativity is now finding that solution and adapting it to
this particular problem.
Basic Principles of TRIZ
 There are three primary findings of this research;
1. Problems and solutions are repeated across industries and
sciences.
2. Patterns of technical evolution are also repeated across
industries and sciences
3. The innovations use scientific effects outside the field in
which they were developed.
 In the application of TRIZ all these findings are applied to
create and to improve products, services, and systems.
 Tools of TRIZ;
- 40 Principles
- Contradiction Matrix
- ARIZ
- 76 Standards
TRIZ Process for Creative Problem Solving

ARIZ is the central
analytical tool of TRIZ.
Provides solution for
complex problems.
is a list of about 85 step-bystep procedures to solve
complicated invention

TRIZ in New Product Development
 The main purpose of TRIZ is same functions but ideal better, more innovative solutions
Simple TRIZ Examples
 Example of Transportation beef
Result: With no extra cost, using avaible resources,
system has been reached shape which is desired.
 Example of airplane’s landing gear
Result : after taking off, pull the gears inside and prevent
the friction
RESULT: We should find real problem and focus
on the real problem for solving.
Example of related focus on
real problem (PIZZA DELIVERY )
 Everybody wants hot and crunch pizza.
 How to solve this problem?
 Design a perfect box
according to altshuller’s
law
 Both save pizza’s hot and
crunchy
Even if order reach to customers
after many hours;
 Sustain freshness
Sailing Boat Example
We are preparing a project for a sailing boat. We want
to increase volume of sail and increase length of pole.

Example of The Boeing 737
A TRIZ problem solving team was called to the Boeing factor in
Seattle, Washington to see how the capacity of the Boeing
737-100 could be increased.
The airplane engine is the moving
object. We would need the engine air
intake and the fuel injection casing to
be larger so the improving feature is
engine volume. the but if we increase
the volume of the engine it will
decrease the clearance distance
between the bottom of the engine
and the ground (worsening feature).
The improving feature is number
7.“Volume of moving object (engine)
and the worsening feature is “3.
Length (diameter) of the moving
object (clearance).
The engine intake area and the cowl with the fuel lines make up
the engine volume, thus an improving feature will be the “7.
Volume of the moving object” and the worsening feature again
“3. Length (engine diameter, i.e., clearance).” This intersection
gives from Altshuller’s tool of 40 Principles.

Approach to problems
 TRIZ provides a structured approach to problem solving,
 TRIZ prevents erratic brainstorming and search for solution,
 TRIZ helps identify and clarify problems and provide good
solution hints.
Idea generation
 TRIZ helps to generate more innovative ideas.
Innovation and new solutions
 TRIZ provide breakthrough innovation and
solution
speed.
 The resolution of problems and arriving at
innovative solutions was achieved in shorter
times.
Future view
 TRIZ provide respondents with a view of how
technologies would evolve in the future and be
put into consideration while planning for the
future.
Team work
 TRIZ appears to have an effect of improving the
effectiveness of teams
 It provides a common language for problem solving
within the group
APPLICATION FIELDS OF TRIZ
CONCLUSION
 Modern TRIZ should not only be seen as a methodology for
solving engineering problems or a new product development
process;
main ideas behind TRIZ become a powerful tool for managing
knowledge and solving problems that contain contradictions in
many areas
