● What is TRIZ?
● Methods of invention and stages of research
● Innovation & Invention
● Levels of Invention
● Ideality and IFR with example
● Understanding Triz
● 39 TRIZ features
● 39*39 Contradiction Matrix
● 40 Altshuller's Principles
● How do we apply triz theory to solve problems
● A Problem solved using TRIZ

What do we do
when we have
to find the
solution of a
problem?
We google it!
That's right.
We try to find the pre existing solutions
of our problem, Because it would save a
lot of time if someone somewhere has
already solved our problem.
TRIZ Uses Same Ideology. 3

What is “TRIZ”?
● TRIZ is a Russian acronym for
“teoriya resheniya
izobretatelskikh zadatch“,
which translates in English as
the “theory of inventive
problem solving“.
● Genrikh Saulovich Altshulleris
considered the father of TRIZ.
● As a patent clerk in 1946
initiated a study of inventive
patents.
● He considered the history of
the successful products and
technologies. 4

Altshuller found ....
that most inventions
seemed to have
similar patterns (40
of them!)
Patterns used in
resolving the
contradictions.
1
Altshuller studied 200 K
Patents..
And Found that only a
small portion are true
innovations remaining
are straight forward
improvements
Today it is 1.4 Million
Patents..
He then classified these
patents
2
Altshuller found ....
True innovation
strived to overcome
contradictions.
For Example:
Contradictions
between opposing
forces like
Speed – Friction
Complexity – Utility

Difference between Innovation and Invention
10
BASIS FOR
COMPARISON
INVENTION INNOVATION
Meaning Invention refers to the occurrence of an idea
for a product or process that has never been
made before.
Innovation implies the implementation
of idea for product or process for the
very first time.
What is it? Creation of a new product. Adding value to something already
existing.
Concept An original idea and its working in theory. Practical implementation of new idea.
Skills required Scientific skills Set of marketing, technical and
strategic skills.
Occurs when New idea strikes a scientist. A need is felt for a product or
improvement in existing product.

The Ideal Final Result
(IFR)
▸ The IFR is the imagined ultimate outcome of the
problem solving process.
▸ Implementation of idea will perform the desired
function(s) by itself with no cost(s) or harmful
effect(s).
▸ IFR provides solutions that are near to the ideality . It
does not increase the complexity of the system
▸ A system performs a function without existing and
without introducing new resources..

“
The IFR has the following 4
characteristics:
1. Eliminates the deficiencies of the original
system
2. Preserves the advantages of the original
system
3. Does not make the system more
complicated (uses free or available
resources).
4. Does not introduce new disadvantages
13

Evolve to Ideality
➢ Each System Performs Some Useful and some Harmful
Concepts.
➢ TRIZ Follows to maximise the Ideality of the system
➢ Ideality measures progress towards IFR.
IDEALITY = ADVANTAGES….
DISADVANTAGES+COST

Creative Solutions
● Can Make magnet based
system For Segregation
● If light weight object can be
displaced by sufficient air,
System based on this
property can be made.
● Density of material can be
calculated and separation
can be done using
appropriate dense fluid
which will sink heavy object
and make lighter one float
without damage
Problem: Segregation
between Products
having same Physical
Appearance(Shape and
Colour) but one is
Heavy and ferrous and
other one is
lightweight
What Resources Do we
Have?
Heavy Object Is
Ferrous and So Its
Magnetic property
should be Useful also
light weight object can
be displaced by air
● High return project but
Time Consuming work
● Needs too much of
manual labour which
company would have to
pay
● Sensor based Segregation
System is out of budget
for Company
What is ideal Final
Result?
We Successfully
segregate the heavy and
Light product with least
Expenditure and on mass
scale

Understanding Triz
So,One can think of TRIZ as another way of Lateral Thinking.
TRIZ is based on two basic principles
1. Somebody, sometime, somewhere has already solved
your problem or one similar to it.
2. Don't accept contradictions. Resolve them.
▸ Use the Defect as a Resource to Solve the Problem
▸ Creativity means finding that solution and adapting it to the
current problem.
▸ TRIZ is an evolving, open-ended system for enhancing
human inventiveness through
▸ Through Systematic identification of problems and ideal
solutions Adapting approaches which worked in other areas.

Problem Statement:
Mountaineering Gear should be strong,
but not heavy.
How to apply triz?

Step 1 - Identify the
contradiction(s)
Here in this example it is
Strength (improves)
versus Weight (worsens)
.
Step 2 -Look at the list
of features and identify
those important to your
contradiction.
Step 4 -
Refer to the TRIZ Contradiction
Matrix to learn which of
Altshuller's Principles may be
useful for this problem.
Step 3 Identify Which
Are Improving Features
and which are
Worsening Features
Strength (feature 14)
improves Weight
(feature 2) worsens
Using Step 4 we can observe:
Row 14 (Strength) and Column 2 (Weight) of the Contradiction Matrix indicate the following Principles may be useful:
40, 26, 27, and 1. We now look at the list of principles to learn that these numbers correspond to
1. Segmentation. 26. Copying 27. Cheap short living 40.Composite materials
Next we brainstorm how we could use these four Principles to solve our problem.

A Problem solved using
TRIZ
An automotive company had a product innovation need related to
the gas cap, so they brought a team together and used TRIZ to
develop an innovative solution.
22

Step 1
First, generate a
problem
statement:
Multiple customer
complaints state
that gas caps are
hard to install, easy
to forget, make
your hands smell
like gas, and make
the check engine
light appear if not
properly closed.
Step 2
Next, generate a
conflict statement:
We want to make it
easy to add gas to
the automobile but
not at the expense
of safety and
functionality.
Step 3
Then, go to the
contradictions
matrix and select
the contradictions
from the list of 39
that best fit the
conflict statement.
We recommend an
online resource
rather than a
complex paper-
based matrix.
Step 4
Finally, expand the 3-4
Inventive Principles and
brainstorm solutions. In
this case, Principles 2
and 25 provided helpful
ideas. When we “single
out the only necessary
part (or property) of an
object,” we realize that
the only function of the
gas cap is to seal the gas
tank filling port. So, we
ask ourselves, can this
be done without the
cap?

24
Here is an example of how we narrowed down our Inventive Principles for a focus:
The TRIZ Matrix proposes the following Principles to solve this
contradiction
● 2: Taking out
● 25: Self-service
● 28: Mechanics substitution
● 39: Inert atmosphere
33: Ease of
operation
30: Object-
affected
harmful
1) Set the contradiction to
solve
The Contradictions Matrix points to
these Inventive Principles based on
the contradictions above:

25
Another clue came from Principle 25:
The solution (we believe first implemented by Ford) was to use a spring-loaded flap in
the fill nozzle. The flap seals the fuel tank in place of the gas cap!
5: Self-service
● Make an object serve itself by performing auxiliary helpful functions
● A soda fountain pump that runs on the pressure of the carbon dioxide that is used to *fizz* the
drinks. This assures that drinks will not be flat, and eliminates the need for sensors.
● Halogen lamps regenerate the filament during use--evaporated material is redeposited.
● To weld steel to aluminum, create an interface from alternating thin strips of the 2 materials.
● Cold weld the surface into a single unit with steel on one face and copper on the other, then
use normal welding techniques to attach the steel object to the interface, and the interface to
the aluminum. (This concept also has elements of Principle 24, Intermediary, and Principle 4,
Asymmetry.),
● Use waste resources, energy, or substances.
● Use heat from a process to generate electricity: Co-generation
● Use animal waste as fertilizer.
● Use food and lawn waste to create compost.

To summarise:
“It is obvious that anything a
scientist discovers or invents is
based on previous discoveries and
inventions.
The same applies to the TRIZ.”
