Hi, Can some one help me knowing about the 'popular principles' among the 40 inventive principles available?

The definition of popularity is subjective. I would say all 40 are popular if we can think using them. The I will define the popularity defined based on how easy one can easily remember certain principles. Principle 1, 2, 10, 12, 35, 22, 25, 7, 3 etc.

I'm not a TRIZ expert, but it is my understanding that the popularity of the principles depends on what type of problem you are facing. If you figure out your contradiction, you can then search to find the most popular principles for the particular solution.

So each principle could be “popular” at a different time.

I hope that helps you.

Hi,

   Thanks for the response prakash/kelly. we are having many methods in innovation problem solving such as directed eveolution, contradiction matrix and  systems thinking. Is there any heirarchy in using these methods (or) these methods can be used for any problem. Also is there any criteria in selecting a problem to solve through inventive problem solving?

There are several tools and techniques emerging for creativity and innovation in last few years. In TRIZ itself, there are many flavors (like the one you mentioned, Directed Evolution) created by TRIZ experts around the world from their experience and research. However, the basic premise for any problem solving is defining the problem better before attempting solutions. Several techniques in TRIZ methodology serve the purpose for defining problems first. Tools such as 9-Windows, IFR, FAA, Su-Field etc can be used for problem formulation before going to contradictions. I recommend a reading by Darrell Mann’s book, Systematic Innovation Hands-On, which explains this neatly. I was asked by several people about the criteria using TRIZ for problems solving. My answer here is NO. (Although I have heard people saying, TRIZ is not a right tool if we can’t find a contradiction) I have seen the TRIZ framework of thinking very powerful in every stage of life!!

There is a list of the 40 Principles listed in the order they are most frequently used in problem solving that I use in my workshops. I do not know the origin of it, but in my 10 years of TRIZ work, I believe it is approximately correct. Again, I have not seen the data from which it was derived. The top ten in this list are:

#35 Transformation of physical/chemical states#10 Prior action/Do it in advance#1 Segmentation#28 Replacement of mechanical system (with chemical, electronic, magnetic, optical)#2 Extraction (eliminate a part/trimming)#15 Dynamicity#19 Periodic action#18 Mechanical vibration#32 Color change#13 Inversion (Do it in reverse)

This would apply to technical contradictions, not physical contradictions where this only one parameter involved.

“… a list of the 40 Principles listed in the order they are most frequently used in problem solving” was published in TRIZ Journal's article “Comparing The Classical and New Contradiction Matrix” by D.Mann, http://www.triz-journal.com/archives/2004/04/01.pdf
