TRIZ - Problems and Contradictions
Introduction
Mary, Mary, quite contrary,
How does your garden grow?
With silver bells, and cockle shells,
And pretty maids all in a row.
Let us take our first step into the world of TRIZ. What did you think of immediately when you saw the first picture on this page?
In TRIZ, the fundamental way of looking at an Inventive Design Problem is to discover and propose Contradictions. These are rendered in as simple and stark a language as possible…the starker the better!
Once we have our Contradiction (and there can be more than one in a given Design Situation !) we can use TRIZ Principles to solve them WITHOUT COMPROMISE.
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?
Some Everyday Objects for us to Contemplate
Contemplate and note down for each Object:
- PURPOSE: What is the Object meant to do? What is its Main Purpose?
- ACCOMPANYING: What are the other Accompanying Objects that it works with?
- KNOBS: What is One Aspect, or Parameter, or Knob for each of the Objects that you have listed, that makes the Object useful?
- SETTING: What are the current Settings/Values for each Knob?
- MEDDLE: Change the Setting of Each Knob to its natural opposite extreme. What Happens? Is it a good thing? When?
- You will see that in many cases, each Knob creates a Certain Outcome at one Setting and another Outcome at the Opposite Setting.
- Are both Outcomes desirable? Do you want “eat your cake and have it too?”
- This could be the source of your PROBLEM / CONTRADICTION !!
In TRIZ, this way of expressing a Problem as a simple Contradiction is referred to as stating an ADMINISTRATIVE CONTRADICTION (AC). (Oh those Russians…).
Later we will use our experience with making metaphors to convert the AC into a more TRIZ-like Contradiction, using TRIZ language.
Let us now consider some examples first and then get some practice at setting up simple AC:
Some Example Contradictions…
We see them everywhere….if one is observant!! Let’s see a few:

How is this for a Contradiction? A shelf in a supermarket carries this placard for a shelf of FRESH JUICE:
