PDMA MN Agenda

• What is TRIZ?
• Tools of TRIZ
• Practice applying TRIZ
• Applications of TRIZ in Product and Services
  development

5
TRIZ IS..

• The Russian acronym for the Solving Problems
  Inventively (pronounced trees )
• Based on observable patterns found in patents and
  literature of how people solve problems
• A system of
• patterns of how people solve problems
• tools to define problems in ways that allow us to
  utilize the patterns for solving new problems.

6
1945 Patent for processing peppers. Force air
inside of the peppers. Suddenly reduce the
pressure. Seeds and stems separate from pepper
body.
7
1950 Patent for removing the shell of cedar
nuts. Under high pressure, water is forced
inside of the shells. When the pressure is
suddenly reduced, the shells break away.
8
1950 Patent for removing shells from sunflower
seeds. Air is forced inside the shells. When
the pressure is suddenly reduced, the shells
break away.
9
AND 27 YEARS LATER..
1972 Patent for breaking artificial diamonds.
Diamonds are placed into a pressure chamber.
High pressure forces air into micro fractures.
Releasing the pressure suddenly breaks the
diamonds into crystals.

Pattern Raise Pressue Slowly Then Suddenly
Release It

• Removing stems from bell peppers
• Removing shells from sunflower seeds
• Cleaning filters
• Unpacking parts wrapped in protective paper
• Splitting diamonds along micro-cracks
• (27 years after pepper patent)
• Producing sugar powder from sugar crystals
• And 200 more!!!

Release It
Or more generally Store up energy and suddenly
release it
Or more generally yet Store up a resource for
later use

Useful Function
Useful Function

• Has useful output (although it may also have
  harmful output as well)
• Is a useful result

14
Harmful Function
Harmful Function

• Leads to a harmful result. No useful results are
  produced.
• A harmful result because it hinders some useful
  function.

Ideality

• All systems evolve toward increasing Ideality
• Ideal System Function is done without existing
• Near Ideal solutions often utilize existing
  resources

PILL INSPECTION WORKSTATION
Vibratory feed move pills around an internal
spiral to top of vibratory bowl where the pills
are discharged and slide down an incline plane
onto a conveyor. As the pills go by, the
inspectors identify and remove the damaged pills.

spiral to top of vibratory bowl where the pills
are discharged and slide down an incline plane
onto a conveyor. As the pills go by, the
inspectors identify and remove the damaged pills.

31
AN ELEGANT SOLUTION-- THE PILL INSPECT ITSELF
Change the escapement for the vibratory bowl so
that the pills are ejected standing on their
edge. Move the conveyor 3 inches. Pills that
are round will roll at a velocity that allows
them to jump to the conveyor. The pills that are
chipped will slide or will roll at a lower
velocity and fall into the trash.
Resource Velocity of the sliding or rolling
pills
Function (inspection of pills) is performed
without the system (human inspectors or video
inspection system).

Small Group Excercise

• Select an aspect of airline food
• Improve an existing feature
• Reduce a negative feature
• Identify an Ideal System and find resources to
  achieve it

Contradictions

• Resolution without compromise

35
Contradictions Defined
Improving one system parameter results in the
deterioration of another system
parameter. Examples Strength vs. Light
Weight Product Features vs. Simplicity and Ease
of Use
36
Piling Problem
Easy to drive
Stays in place
37
Contradictions
B
A
A and B are desireable features of the system.
38
Contradictions
Improving one feature harms the other feature.
39
Contradictions
B
Improving one feature harms the other feature.
A
40
Contradictions
There exists a control feature of the system that
ties the two desireable features together.

Contradictions
A
When the control feature is small or absent, one
of the features increases while the other
decreases.
B

Contradictions
B
When the control feature is large or present, the
second features increases while the first
decreases.

Separation PrinciplesSpace
Example Strength vs Weight of a plastic
panel The control parameter is thickness.
Reinforcing ribs are placed only where additional
strength is needed.
46
Contradictions - Jet Engine
Boeing wanted to install larger engines on a
redesigned 737. A larger air intake would reduce
ground clearance to unacceptable levels.
Contradiction Increasing air intake reduces
ground clearance Control parameter Intake radius
47
Contradictions - Jet Engine
Resolve the contradiction by Separation
Make the radius large laterally for high air
flow. Make the radius smaller downward for high
ground clearance.
48
Separation PrinciplesTime
At time 1, C is small
At time 2, C is large
49
Separation PrinciplesTime
Example Strength vs Lightweight of a automobile
frame The control parameter is thickness.
Reinforcing brackets are needed for shipping the
vehicles but not for normal operation. The
weight degrades fuel economy. The brackets are
bolted on at the factory and then removed at the
dealership.

Separation PrinciplesParts From the Whole
Large company composed of small semi-autonomous
divisions to keep small company responsiveness.

Separation Principles Under Conditions
Example Privacy Glass There is a liquid crystal
film (made by 3M) that can be laminated to a
window. When there is no current applied to the
film, the film is opaque. When a current is
applied, the liquid crystals align and the film
is nearly transparent.

pile is not turning, the threads stop the
