TRIZ - A Very Contradictory Method

• Big Idea : Generalized Problem: “Your Problem has been solved somewhere else” in a different DOMAIN in a different LANGUAGE

• Modelling/Applying : “Metaphorize” your Problem using 48 TRIZ Parameters

• Taxonomy / Tools :

• The 8 TRIZ Laws of Evolution of a Product;

• TRIZ Contradictions Matrix;

• TRIZ 40 Inventive Principles

• Use your CULTURAL CAPITAL and your DOMAINs to write a PROBLEM in simple English
• Ask: 5W+H
  • What does the problem seem to be?
  • Who has the problem?
  • When does the problem occur? All the time? Under certain circumstances?
  • Where does the problem occur?
  • Why does the problem occur?“Ask why 5 times” – W. Edwards Deming - How does the problem occur?

• Ellen Domb, “How to help TRIZ Beginners Succeed”
• Adobe Workfront Blog, “The 5 Ws (and 1 H) that should be asked of every project!”
• Cultural Learning Alliance: “What is Cultural Capital?”
• “Platform Creativity: Domain, Field, and Person”
• Rudyard Kipling, “I Keep Six Honest Serving Men”

To refine our Problem, what Resources do we have?

• One Good way to do this is using the Ishikawa Diagram
• Man, Material, Method, Management, Machinery (Ishikawa)
• This diagram is used primarily to assign CAUSES
• But it conveniently lists all the Resources.
• What things create the compromise/tradeoff?

• The Ishikawa Diagram is also called the Fishbone Diagram or Cause-and-Effect Diagram.

• From the Ishikawa Diagram
  • What is One Parameter or Knob for each of the Causes that you have listed therein?
• Let us make a list for each Knob/Object:
  • What is the Knob meant to do? What is its main Purpose?
  • What are the other Accompanying Objects that it works with?

• What are the current Settings for each Knob?
• Change the Setting of Each Knob to its natural opposite extreme. What Happens?
  • You will see that in many cases, each Knob creates a Certain Outcome at one Setting and another Outcome at the Opposite Setting.
• This is the Source of your Administrative Contradiction !! ]
  What sort of Contradictions do we see in these familiar objects? What is good and what is not so good? Could that be the source of a problem to solve?

• I like Tea in the Mornings..and Afternoons and Evenings..and…
• Comes forth from your…Cultural Capital and Domains. Thanks to Pierre Bourdieu and Mihaly Csikszentmihalyi for giving us those two Words!!
• Possible Problem Statements
  • Milk Boils Over
  • I am Bored Watching the Milk boil

• Use the Ishikawa Diagram to Refine the AC
• Again use your Cultural Capital and Domains
  • Watching the Milk is a Bore!!Can I do something else in the meantime?
  • But: the Milk will boil over…
• AC:
  • I can either boil Milk, OR do something else, NOT both.

• Use the Ishikawa Diagram:
• Man: Me?
• Method :
  • Operating the Stove
  • Wanting/Doing Two Things at the Same Time
• Material: Milk, Vessel, Stove, Gas, Time, Heat
  • Milk boils over when it is heated

• State an Ideal Final Result
• A basic principle of TRIZ is that systems evolve towards increased ideality, where ideality is defined as

\[Ideality = Benefits / (Harm + Costs)\] - Evolution is in the direction of - ⬆ Increasing benefits - ⬇ Decreasing costs - ⬇ Decreasing harm - IFR allows us to invert the direction of the problem: to come backwards from Solution towards the Situation

The extreme result of this evolution is the Ideal Final Result: - It has all the benefits,
- none of the harm, and - none of the costs of the original problem. - The Ideal Final Result describes the solution to a technical problem, independent of the mechanism or constraints of the original problem. - It occupies no space, has no weight, requires no labour, requires no maintenance.

• One Worsening Parameter: 17: Energy Usage by Stationary Object (Stove is ON !!)

• One Parameter to Improve: 21: Stability ( Milk must NOT boil over !!)

• INVENTIVE PRINCIPLES from the Matrix:

• 35: Parameter Change

• 18: Mechanical Vibration

• 24: Intermediary

• 9: Prior Counteraction

• 3: The Other Way Around

• 35: Parameter Change

• 15: Dynamization

• 2: Taking Out

• 18: Mechanical Vibration

A Milk Watcher Device - This is dropped into the vessel before pouring the milk - It vibrates when the milk is boiling and prevents spillage - And of course, there is a patent. Yes , in Russia, where else !!

Milk Saver Patent Web Page!!

• What “Parameter” can we change?

  • Temperature?

  • Rate of Gas?

  • Kind of metal used in Vessel?

  • Smoothness of the Vessel finish?

Here are some solutions using Parameter Change - Sprinkle Water on the Froth…Umm

• Apply butter to the rim of the vessel beforehand !!
• This is also a solution derivable from IP-9: Prior Counter Action
