OBJECTIVES

Briefly review the concepts of TRIZ Ideality, resources, patterns of invention

Explain and demonstrate the use of “reverse” TRIZ thinking in forecasting and planning

NOTE: All day workshop on TRIZ problem solving and forecasting on Tuesday at WFS



WHAT IS “TRIZ” ?

A Russian acronym:Theoria Resheneyva Isobretatelskehuh

Zadach

(Theory of Solving Problems Inventively)



WHAT IS “TRIZ” ?A way of thinkingA family of tools, thinking processes,

and software

The “way of thinking” can ALWAYS be used, but the tools in the tool kit can be selected depending the nature of the problem, time available, etc.


INNOVATION-TRIZ,INC.BASICS OF OTHER

CREATIVITY TOOLS Psychology more than science and technology

DeBono, Lateral Thinking/Six Hats™, Creative Problem Solving Can discuss integration

Randomness Brainstorming, picture, etc. stimulation Can discuss integration

Highly dependent upon facilitation skills Fine for simple problems and can be easily learned Limited by knowledge in the room--TRIZ looks

outside the knowledge and experience in the room in a systematic and structured way



THE HISTORY OF TRIZ A discovery of a talented patent examiner for the Russian

navy, Genrich Altshuller, 1950’s Originated from the study of several hundred thousand of

the world’s most inventive patents--now in the millions He recognized that the development of technological

systems follows predictable patterns that cut across ALL areas of technology--the speed of technical evolution can be accelerated

Also recognized that problem solving principles are also predictable and repeatable--anyone can invent!

Established schools to teach after a Stalin 7 yr. prison term--deceased in 1999 at age 71



BASIC CONCEPTSSystems evolve toward IDEALITY

irreversiblyUsing RESOURCES within the system or

easily convertibleResolving CONTRADICTIONS as they

evolvePATTERNS OF INVENTIONS/OPERATORS

are constantly recognized and used



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

INNOVATION-TRIZ,INC.SYSTEM PROPOSAL AND CHALLENGE

Replace inspectors with a $200K video inspection system

High return project, but capital is not available

Boss says, that’s a great idea, but “Find another way!!”



GOOD PILLS/BAD PILLSWhat is IDEALITY?

What are the RESOURCES we have?

INNOVATION-TRIZ,INC.An Elegant Solution: The Pill

Inspects 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).

COMBINES…..The rigor of the TRIZ process, but in

reverseProactive, rather than checklist,

mental process



REVERSE TRIZ

Formulate original problem (the “ideal” final result)

Invert the original problem (the opposite of the ideal final result/ideality)

Amplify the inverted problem: reverse ideality

Search for information and resourcesHypothesis, tests, and correction

INNOVATION-TRIZ,INC.THE REVERSE TRIZ

APPROACHThe problem: I want to prevent a leakInvert the problem: I WANT to have a leakExaggerate/amplify the inverted problem:

I WANT to have a CATASTROPHIC leak, causing MAJOR damage and public affairs impact

What RESOURCES do I need to have/cause a leak?

WORKSHOPI want to have a successful workshopI want to have an unsuccessful workshopI want to have the WORST workshop the

WFS has ever hosted--no one ever comes again and WFS loses a ton of money!

How would I make sure this happened?What resources do I need?



VS. OTHER PROCESSES Compared to the HAZOP or FEMA checklist

process, generates far more real possibilities, puts people in an aggressive mind set, and finds possibilities not otherwise found

Software supported Larger knowledge base Use inventive skills and thinking from traditional

TRIZ problem-solving



USES Failure prediction for projects and

product designsFailure prediction and/or analysis for

technology developmentsFailure prediction for technology

adoption and commercializationFailure prediction for

management/organizational processes



EXAMPLESHow would I prevent this product

from being successfully used?How would I make sure that this new

technology would never be adopted?



WALL STREET JOURNAL03/29/1999

Ford to Recall 945,000 Cars, Trucks to Fix Cruise Control DEARBORN, Mich. - Ford Motor Co. is warning owners of 945,000 1998 and 1999 model cars and trucks not to use the cruise-control feature because of a potential defect that could cause the accelerator to stick open.

The auto maker said it knows of no accidents related to the problem, which company engineers discovered during tests, a Ford spokeswoman said. The vehicles will be recalled and repaired at no cost to customers starting in May when Ford gets replacement parts, the spokeswoman said. In the meantime, customers may get the cruise-control mechanism disabled, the company said.

The models affected are about 567,000 1998 and 1999 Explorer and Mountaineer sport-utility vehicles; about 166,000 1998 and 1999 Ranger pick-ups; 99,000 1998 and 1999 Mustangs; 88,000 1999 Super Duty F-Series trucks and about 25,000 1999 Super Duty F-Series stripped chassis.

To alert owners to the problem, Ford is sending letters and directing customers to a Web site, www.recall.ford.com, where they can enter the vehicle identification number to learn if their car or truck is affected.



APPLICATION AT DIFFERENT LEVELS

The principles of TRIZ and “reverse” TRIZ can be applied at different system levels from a competitive standpoint

Need to understand what those levels are and how they might affect us

What are potential negative events and causes at DIFFERENT levels?


INNOVATION-TRIZ,INC.FOR EXAMPLE…..

AIRLINE HIJACKINGLevels

The cockpit The plane The boarding area The airport The space around the airport The atmosphere



FOR EACH LEVEL….What resources are available to

deliberately cause the unwanted event?



TAKEAWAYS

Try the “reverse” TRIZ process (“how” vs. “what”) for some failure or forecasting problem you currently have

Substitute and compare this process with ANY checklist process currently used
