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.

答案是Mobius Strip

Examples on patterns of how people solve problems

1945: Patent for processing peppers Force air inside of the peppers. Suddenly reduce the pressure. Seeds and stems separate from pepper body.

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.

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

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 Pressure 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!!!

Pattern: Raise Pressure 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

Let’s start

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. Damaged Pills Conveyor Trash Can

GOOD PILLS/BAD PILLS • What is IDEALITY? • What are the RESOURCES we have?

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. Damaged Pills Conveyor Trash Can

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). Trash Can
