TRIZ - The Unreasonable Effectiveness of Available Resources
Introduction
In the previous Module on Problems and Contradictions we understood how to identify an Administrative Contradiction in everyday situations. This is the first and most important step in the TRIZ Problem Solving Method.
Another important idea in TRIZ is that of Available Resources. Let us appreciate this idea with the help of two games.
Available Resources: Game #1
You have to Stick the lighted candle to the Wall in such a way that the melting wax does not drop on to the floor. Your resources are:
- Candle
- Matchbox
- Thumbtack
Available Resources: Game #2
Look at the graph below: does it remind you of something you know very well?
What does this graph represent?
Let us pretend we are part of this graph and see where our Problem Formulating Skills take us!

A comparable switch of attention occurs in an old joke about a worker in a high security factory, in which the employees were carefully watched when they left at the end of their work day. On a particular day, this worker was stopped at the factory gate as he walked out with a wheelbarrow full of styrofoam packing peanuts. He explained that he had salvaged these from the trash, and was planning to use them in shipping gifts to his grandchildren. Searching through this packing material, the guards found nothing, and so they let the man go home. The following week the same thing happened, and the worker was again stopped. But he offered the very same story, and when the guards searched through the packing peanuts and found nothing, he was allowed to leave. But this continued, week after week, until the guards could no longer believe that one person would want or could make use of so much packing material. Finally, the man was held for interrogation, at which time he admitted that he had absolutely no use for packing peanuts - and that, all these weeks, he had been stealing wheelbarrows.
Hearing this joke, I am reminded of the phrase โpart and parcelโ, which is a rough equivalent of โfigure and groundโ, the Gestalt Principles. Throughout most of it, the packing peanuts occupy center stage as figure (part), while the wheelbarrows (which function merely as containers) are completely ignored as innocuous ground (parcel). At the end of the joke, there is an unexpected twist, a switch of emphasis, a recentering, when we learn that the parcel is really the part.
This should also remind us of the Guilford Alternative Uses Exercise that we did, where we forced ourselves to leave the โregular useโ of an object behind and think of it as serving quite another function.
