©2002 Inventive Solutions, Inc. 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.

©2002 Inventive Solutions, Inc. 1945: Patent for processing peppers. Force air inside of the peppers. Suddenly reduce the pressure. Seeds and stems separate from pepper body.

©2002 Inventive Solutions, Inc. 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.

©2002 Inventive Solutions, Inc. 1950: Patent for removing shells from sunflower seeds. Air is forced inside the shells. When the pressure is suddenly reduced, the shells break away.

©2002 Inventive Solutions, Inc. AND 27 YEARS LATER… : 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.

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!!! Pattern: Raise Pressue Slowly Then Suddenly Release It

©2002 Inventive Solutions, Inc. Pattern: Raise Pressue Slowly Then Suddenly Release It Or more generally: Store up energy and suddenly release it Or more generally yet: Store up a resource for later use

©2002 Inventive Solutions, Inc. AN ELEGANT SOLUTION-- THE PILL INSPECT ITSELF Trash Can 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).

©2002 Inventive Solutions, Inc. 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

©2002 Inventive Solutions, Inc. Contradictions A B A and B are desireable features of the system.

©2002 Inventive Solutions, Inc. Contradictions A B Improving one feature harms the other feature.

©2002 Inventive Solutions, Inc. Contradictions Improving one feature harms the other feature. A B

©2002 Inventive Solutions, Inc. Contradictions AB There exists a control feature of the system that ties the two desireable features together. C

©2002 Inventive Solutions, Inc. Contradictions A B When the control feature is small or absent, one of the features increases while the other decreases. C

©2002 Inventive Solutions, Inc. Contradictions A B When the control feature is large or present, the second features increases while the first decreases. C

©2002 Inventive Solutions, Inc. Contradictions AB What we want is c small to give large A and c large to give large B. C C

©2002 Inventive Solutions, Inc. Contradictions Resolve by Separation AB Space Time Parts From the Whole Upon Condition C C

©2002 Inventive Solutions, Inc. Separation Principles Space Example: Strength vs Weight of a plastic panel The control parameter is thickness. Reinforcing ribs are placed only where additional strength is needed.

©2002 Inventive Solutions, Inc. 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

©2002 Inventive Solutions, Inc. Contradictions - Jet Engine Make the radius large laterally for high air flow. Make the radius smaller downward for high ground clearance. Resolve the contradiction by Separation

©2002 Inventive Solutions, Inc. Separation Principles Time C A B At time 1, C is small C A B At time 2, C is large

©2002 Inventive Solutions, Inc. Separation Principles Time 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.

©2002 Inventive Solutions, Inc. Separation Principles Under Conditions C A B Condition 1, C is small C A B Condition 2, C is large

©2002 Inventive Solutions, Inc. 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.
