BEFORE WE START….LET’S BENCHMARK

    • MACHINE REPLACES MAN
  • CASE STUDY
  • A robot was brought to a plant to operate a machine. After it was rigged up and switched on, the elderly worker who had operated the machine for years was amazed at seeing the nimble “iron man” performing all the necessary steps.
  • A half an hour later, however, the robot came to a standstill, to the bewilderment of the service team of electronic engineers. What happened? As it turned out, some chips had fallen from the workpiece into the moving elements of the machine. This situation where a human worker would simply flip the chips away with a broom and continue working brought the robot to a deadlock. The engineers cleaned the machine with a broom, switched on the robot…only to see the robot stop again. How could this problem be solved? Obviously, one cannot attach a human worker with a broom to the robot……

what is triz
WHAT IS “TRIZ” ?

A Russian acronym:

Theoria Resheneyva Isobretatelskehuh Zadach

(Theory of Solving Problems Inventively)

what is triz7
WHAT IS “TRIZ” ?
  • A way of thinking
  • A family of tools, tool kits, and software

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

the history of triz
THE HISTORY OF TRIZ
  • A discovery of a brilliant patent examiner for the Russian navy, Genrich Altshuller, 1950’s--studied hundreds of thousands of patents
  • 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
  • “Reverse” TRIZ was developed around 1970
what to use triz for
WHAT TO USE TRIZ FOR
  • Level 2-4 problems
    • 1--straightforward engineering design
    • 2--simple contradictions
    • 3--difficult design and manufacturing contradictions (WHAT IS NORMAL APPROACH?)
    • 4--extremely difficult system design problems (“intestine problems”)
    • 5--invention of new science
  • Level 4 can require looking at hundreds of thousands of potential solutions and take many years of effort within an organization

vs other creativity tools
VS. OTHER “CREATIVITY” TOOLS
  • Based on science and not psychology
  • Takes time to learn and practice
  • Time consuming on the problem definition side--pays dividends, but some people prefer to solve the wrong problem several times and appear to be doing something useful
the output of the process
THE OUTPUT OF THE PROCESS
  • Generates solution paths and concepts of solution, NOT engineering drawings and detailed plans
  • A better, more clearly defined problem and project
  • New and nearly exhaustive set of concepts

“A GOOD THING”

  • Psychological inertia is “good”
    • Basis for our brain’s stability
    • Usually good that we follow it
    • Protects the mind from doing unproductive work
    • Utilizes past experiences and knowledge
      • Good that we can remember, memorize and use
      • Storage of ready-made decisions keeps the brain free which allows work to be done in parallel
    • Basis for stable society
      • Any kind of change is potentially bad or dangerous
      • There is always a need to stabilize situations

A “NORMAL” PERSON’S VIEW...

How does a centrifuge work?

the baker s view

INNOVATION-TRIZ,INC.

THE BAKER’S VIEW

The Waissenberg Effect

When the motion of certain liquids is altered, the liquid achieves a highly plastic state. This state is caused by stress which is normal to the plane of the altered motion. For example, if a rotating shaft emerges from a pool of liquid, the liquid will rise along the shaft. This effect is observed in solutions, in molten polymers, and in gels of low molecular weight. The effect is used to develop extruders that do not use spiral impellers. A characteristic of this effect is that, as the speed of motion increases, the stability of the flow decreases

parallel universes
PARALLEL UNIVERSES
  • Many other industries or technologies face the same type of problems in a generic sense
  • It’s almost impossible to follow all areas of technology, read all literature, go to all meetings
  • Accidents or alerts sometimes change this, but it is normally not proactive in most organizations
  • In planning the future, it is CRITICAL to be aware of advances in ALL fields of technology
  • Advances in unknown areas can forecast advances in known areas
why is this important

Ideality

All Useful Functions

All HarmfulFunctions

=

The ideal system performs a required function without actually existing. The function is often performed using existing resources. ALL systems evolve in this direction over time by resolving contradictions.

slide49

HOW DO WE GET TO IDEALITY?

  • TRIZ provides two general approaches for achieving close-to-ideal solutions (that is, solutions which do not increase system complexity):
    • Use of resources
    • Use of physical, chemical, geometrical and other effects (remember the Waissenberg effect?)

-

slide50

WHAT’S A RESOURCE FROM A TRIZ PERSPECTIVE?

  • A resource:
    • is any substance (including waste) available in the system or its environment
    • has the functional and technological ability to jointly perform additional functions
    • is an energy reserve, free time, unoccupied space, information, etc.

INNOVATION-TRIZ, INC. THE WALL STREET JOURNAL 03/29/1999

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 caror truck is affected.

what is your checklist for avoiding this result

The Russian navy, in the early years of the cold war, developed sophisticated combustion technology which allowed a ship to sail under power without a significantly visible smoke trail, making observation by airplanes or satellites very difficult. On its first trial, the ship sailed out and no visible smoke trail could be seen. As a backup precaution, a picture was taken from an airplane, the picture developed, and a smoke trail was seen in the photo. After rechecking all logistics and procedures, the trial was repeated and exactly the same smoke trail in the photo was observed.

Checklist for this workshop--let’s revisit from an reverse TRIZ standpoint

case study the exploding drum
CASE STUDY:THE EXPLODING DRUM

An overseas shipping system for a highly corrosive chemical has been designed to avoid the expense of using a very expensive reusable, corrosion resistant container. The container is basically a 30 gallon container made of steel (known to be corroded by the product, but rate is steady and known) thick enough to withstand the corrosion that occurs during transit. The liquid is distilled away from the corrosion products at the overseas destination. One trip is made successfully, but during trip #2, several drums rupture and cause a major toxic release on board the transport ship. Analyze this problem using the TRIZ tools in reverse and identify the root cause and suggest possible solutions if it is desired to continue the operation.

  • These patterns can be revealed from the patent literature and analysis of system development and purposefully used for systems development without numerous blind trials

  • TRIZ can be viewed as a threat (as opposed to a breakthrough productivity tool) by certain senior technical staff who can’t believe the solution to a problem may lie outside their area of expertise
