Notice (Toru Nakagawa, Oct. 17, 2014)

For better introduction to TRIZ, you are advised to visit either one of the following four 'Entrance Pages' depending on your interest:

 Entrance page C: Let's enjoy 'Think & Try' ! (for Children and Highschool students)

 Entrance page S:  For solving problems creatively (for Students and the General public) 

 Entrance page E:  Methods of creative problem solving (for Engineers and Researchers novice to TRIZ) 

 Entrance page P:  Practices and methodologies of Creative problem solving (for Practitioners and Experts)   

The present page is going to be remodeled but not ready yet. 


What is TRIZ?
   Why don't you learn TRIZ and improve your creation capability?         [T. Nakagawa  Nov. 1, 1998]

TRIZ is "Theory of Inventive Problem Solving".
     Abbriviated from its original Russian name written in English alphabets.

It supports creative R&D in technology.
      It clarifies your technical problems and suggests you a lot of creative hints.

 It is based on the "Priciples of Invention" extracted from the history of technological innovations.
      2.5 Million patents over the world were analyzed for condensing their innovative essences.

 For solving your problem, you will be able to access to the full world of science and technology.
     From you technical target you can retrieve principles in physics, chemistry, and geometry.

 It guides you to breakthroughs instead of trade-offs.
     By solving contradictions, you will reach real inventions and valuable patents.

You will master a thinking method of breaking mental inertia for technological innovation.
     Helpful for experienced people as well as for younger people.

Mr. G. Altshuller originated and established the methodology since 1946 in the former USSR.
     In CIS, many TRIZ courses are carried on in institutes and highschools.

After the end of the Cold War, it became known and was evaluated highly in USA, Europe, Japan, etc.
     Introduced rapidly and is forming a new wave of movement for technological innovation.

TRIZ methodology is now applicable with software tools on personal computers.
     They show technology knowledge bases with illustrations and allow smooth operation.

It is applicable in mechanical, electrical, chemical, and many other much wider areas.
     Areas of knowledge bases and applications are now being extended.

The TRIZ methodology for problem solving is illustrated in the following figure.
     The symbol mark of this home page was designed by Nakagawa from this figure.


                Essence of TRIZ in 50 Words    (Toru Nakagawa, May 22, 2001)

Essence of TRIZ:

Recognition that
    technical systems evolve
       towards the increase of ideality
       by overcoming contradictions 
       mostly with minimal introduction of resources.

Thus, for creative problem solving, 
   TRIZ provides a dialectic way of thinking,
       to understand the problem as a system, 
       to image the ideal solution first, and 
       to solve contradictions. 

     USIT is a simple yet effective procedure for creative problem solving with the essence of TRIZ.
