Introduction Teoriya Resheniya Izobreatatelskikh Zadatch Theory
of inventive problem solving. Started with Altshullers interest in
invention and work in Soviet Navy patent office 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 1. Six Sigma processes 2. Project management and risk
management systems. 3. Organizational innovation initiatives.
Genrikh Saulovich Altshuller (1926- 1998) Soviet engineer,
inventor, scientist, journalist and writer
Slide 4
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.
Slide 5
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

algorithm of inventive problems solving (ARIZ) ARIZ is the
central analytical tool of TRIZ. Provides solution for complex
problems. is a list of about 85 step-by- step procedures to solve
complicated invention problems

TRIZ and Our Earnings Samsung Electronics: Euro 1.5 billion,
more than 3,000 patents. Viko Ford, brake systems. Boeing
Corporation Euro 1 billion in value added. Intel company declared
TRIZ is an Intel's innovation platform of the 21st century.

TRIZ in New Product Development The main purpose of TRIZ is
same functions but ideal better, more innovative solutions
Slide 22
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 airplanes landing gear
Result : after taking off, pull the gears inside and prevent the
friction
Slide 23
RESULT: We should find real problem and focus on the real
problem for solving.
Slide 24
Example of related focus on real problem (PIZZA DELIVERY )
Everybody wants hot and crunch pizza. How to solve this
problem?
Slide 25
Design a perfect box according to altshullers law Both save
pizzas hot and crunchy Even if order reach to customers after many
hours ; Sustain freshness
Slide 26
Sailing Boat Example We are preparing a project for a sailing
boat. We want to increase volume of sail and increase length of
pole. 1234 Weight of moving objectWeight of stationaryLength of

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.
Slide 29
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).
Slide 30
Slide 31
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
Altshullers tool of 40 Principles. 4. Asymmetry 1. Segmentation 7.
Nested Dolls 35. Parameter Changes
Slide 32
And result of engine according to TRIZ
Slide 33
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.
Slide 34
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.
Slide 35
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
Slide 36
APPLICATION FIELDS OF TRIZ
Slide 37
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
