TRIZ: Теория решения изобретательских задач
Theory of Inventive Problem Solving (TIPS)

To be able to
develop strong solutions!!!
=
Evolution

Where inspiration
comes from?
There are Big and small problems

A writing desk that is uncomfortable,
or a noisy office

overcrowded cities, traffic roads

Houses with no room for washing machines

Nevertheless,
life gradually
becomes more
and more
comfortable,
annoying
problems are
solved and stop
disturbing
us

Life is more comfortable than 20 years ago

Innovtion is
elegant solutions
for common
problems

Solutions must
be
Elegant to
impact

¿What is TRIZ?
Systematic Innovation

• TRIZ is a methodology, tool set, knowledge
base, and model-based technology for
generating innovative ideas and solutions for
problem solving

•Solve problems
•Improve products
•Redesign Operations
•Understand people
TRIZ applications:

• Principle Matrix:
• 39 Parameters
• 40 inventive principles
• Analysis field – substance (76 standard solutions)
• Separation of field and space (76 standard solutions)
• Physic Effects and laws
TRIZ structure:

Basic Steps for applying TRIZ:
1. Contradictions stated
2. Define the ideal final result
3. Translate to parameters (39 features)
4. Find the inventive principles at the Matrix
5. Analyze the principles that could help
6. Use principles to propose solutions

1 Principle: Segmentation
• Painless injection:
Japan 2003: While
injecting, it makes but a
small cut and practically
does not cause pain.
Contradiction:
Have constant flow in a
syringe needle W/O
harm to the nerves.
Solution: 200 silicon
superfine needles in a patch

Examples: 2nd Princple: Extract
Extract only the part that is
necessary:
a) iwaycard: trasmits the
photos directly to the
ipod without itunes or a
computer.
b) Mosquito Repeller:
Extract sound from a
predator and cast it.

Principle 5: Merging
• Combine TV and Mirrors:
a) Will save wall space
b) Have the image while
brushing or shaving

Principle 21: Rushing through
• Sterilizing potatoes
• A potato can rot due to naturally-occurring bacteria on its
surface. Heat kills the bacteria, but too much heat will cook the
potato as well.
• If the potatoes are exposed to a flame at 500-850 degrees C for
a short duration (4 to 8 seconds), the surface bacteria will be
destroyed while the inside of the potato is
unaffected.

Principle 26: copy
• MRI: Without opening the
head we can have an
image of it. We copy the
content to an image and
we can assume that we
see inside a head

Case 1:
• Parents often encounter the following problem -
shoes bought for a child become too small for
him or her in a month or so. It is necessary
either to buy new shoes or to buy too big shoes
• Superficial Contradiction: feet grows but shoes
does not.
• Parameters:
Exercise: Find the parameters !!!

Case 1:
• Reality: parameter could be from 3, 5 or 7 vs
3-8, the matrix only allows : 3 vs 5 or 3 vs 7
5 vs 7 or 8 vs 7
Constraint: one element should be in movement
because we walk.

Translate to parameters/ ideal
• Ideal Result:
To have less shoe expenses (Count-cost), with
comfortable shoes for teenagers
• Contradiction (intensified contradiction):
Length of the moving object (feet) is not
supported by the volume of a static object
(Shoe).

• 5 min for questions and loud thinking.

Contradiction:
• I want to know everything that my kids do, but I don't know
everything that my kids do.
• I want to have any tool by hand, but I do not want to have
inventory or walk around heavy
• I want to eat as much as I want but I don't want to get fat

Type of contradictions
• 3 types of contradictions:
Physical: A and anti- A.  A-A
Technical: A but B  A+B
Human : A despite B  A
Recommended tools.
Physical: Separation of space of time +76 solutions
Technical: Matrix of contradictions
Human: Soft system methodologies

Technical A but B (Trade off)
• If a boat gaing weight, it looses the hability to
float
• Si agrego desmoldante a una pieza plástica
pierdo adherencias de un pegamento en un
proceso posterior
• If I ask for more information "the system" will be
stressed out, if I don't ask for information I
loose clarity of the problem

Physical contradiction: A anti A
I want passionate employees but I want
objective employees

Human contradiction: A despite B
I will get married with or without your
or even despite of you

Contradictions:
• Classify these contradictions: Physical, Technical or Human
*I had a rise even when my targets were not met
*I want to have free access but I don't want anyone else to enter to my home
*I want to have a healthy life & a great look but I don't want to exercise
•Improve the power of a vacuum cleaner will
increase the cleaning quality but leads to
increasing noise & weight
•We need increase communication face to face
But we do not have the same time available
during the day to hold a meeting

Exercise:
• My most important machine of Bangalore's
location fails continuously.
The electrical system is changed every time a
shortage appears because the supplier sells
the system as a whole spare part.

Examples of physical contradiction:
•The holding wire must be thick in order to withstand the pulling
force and the wire must be thin to minimize the
force (that cuts the roll) and reduce material consumption
Separation in time & Space :
thin but in the begining and end

Needle eye:
• It is difficult to pass a thick thread
through the small eye of a needle.
We can formulate the following
physical contradiction to represent
this situation: A needle must have
a large eye to facilitate insertion of
the thread, and must have a small
eye for convenient sewing.
• By separating the contradiction in
time this problem can be
formulated as follows: the eye
must be large while the thread is
inserted, and must be small
during sewing,

Market trends:
• Individually vs Tribalism
• Little luxuries
• Women in to market
• Third places between home and work
• Sedentary life style
• Obesity
• Guilt
• Being alive
• Travel & Vacation
• Life long Learning
• Ubiquitous Computing
• Virtual
• Future Tense
• Security and paranoia
• Environmental awareness
• Simplicity
• More litigation

Which trend is present?
• Tribal marketing n. A marketing strategy that attempts to create social groups or communities
that are centered around a product or service. The credo of tribal marketing is that postmodern
people are looking for products and services that not only enable them to be freer, but can also
link them to others, to a community, to a tribe. Belong by choice

• Ubiquitous Computing
Ubiquitous computing – Making many computers available throughout the physical environment,
while making them effectively invisible to the user. Ubiquitous computing is held by some to be
the Third Wave of computing. The First Wave was many people per computer; the Second
Wave was one person per computer. The Third Wave will be many computers per person.
Three key technical issues are: power consumption, user interface, and wireless connectivity.

• Oldenburg calls one's "first place" the home and those that one lives
with. The "second place" is the workplace — where people may
actually spend most of their time. Third places, then, are "anchors" of
community life and facilitate and foster broader, more creative
interaction.

Contradictions:
• Classify these contradictions: Physical, Technical or Human
*I had a rise even when my targets were not met (Human)
*I want to have free access but I don't want anyone else to enter to my home (Physical)
*I want to have a healthy life & a great look but I don't want to exercise (Technical)
•Improve the power of a vacuum cleaner will
increase the cleaning quality but leads to
increasing noise & weight (Technical)
We need increase communication face to face
But we do not have the same time available
during the day to hold a meeting (Physical)

Solutions
•
Garbage can possible solution:
• If you generate a lot of organic trash during the
week, chances are your trashcan doesn’t smell
the freshest after a few days. And if you
happen to have a large family, your trashcan
can probably can get down right funky in a
short period of time. One concept designer,
however, has a solution for the problem of
stinky trash. Freeze it.
