Need for Systematic Innovation :

Corporations seek innovative solutions to engineering problems, quickly and with fewer resources, to maintain a competitive edge in an era of downsizing. This is required to improve their products and processes so that they can maintain their leadership and share in the market.

However, human nature, specialist training, habits, paradigms and the working environment constrain our innovative thinking. This is called "psychological Inertia" and it has to be overcome to obtain innovative solution concepts for the chronic technical problems.

TRIZ is apparently the only scientifically based systematic methodology that overcomes the "psychological inertia" and produces a large range of solution concepts in a much shorter time-scale while utilizing available resources. This directly results in improved product at reduced cost,

What is TRIZ ?

TRIZ is a Russian acronym meaning "Theory of Inventive Problem Solving". In 1946, Genrich Altshuller, the founder of TRIZ, was a patent reviewer at the Russian naval patent office at the young age of 20. He perceived that there is a definite pattern in the way innovations take place in technical systems. He started a study of 400,000 patents to look for the basic principles and patterns in the world's most innovative patents. The collated patent database and subsequent analysis revealed a natural pattern of innovation that can help solve similar technological problems. This study was continued, by Altshuller and his disciples, over the past 50 years and has yielded a systematic approach to definition and identification of innovative problems, a set of problem solving tools, and a vast knowledge database, which can help solve current technical problems in an innovative way. Today, the TRIZ software database includes the essence of over 2,500,000 patents.

How will TRIZ help in INDIA ?

Indian industries have been primarily borrowing technologies from West and Japan. However, there are three main difficulties, TRIZ can help, in all the three cases, with quick results using fewer resources, to maintain a competitive edge and hold the market share.

      1. Next generation product and/or New customer requirements
          1. è TRIZ tool - Trends of Technical Evolution
      2. Some products need to be modified to suit
        1. availability of new raw materials
          1. è TRIZ tool - Ideal Final Result and Resources
        2. new processing equipment
          1. è TRIZ tool - Functional Analysis / Trimming
      3. Chronic engineering problems need to be solved
                ("chronic" implies that all known methods have been tried)
            è TRIZ tool - Technical or Physical Contradictions elimination
            è TRIZ tool - Substance-Field Analysis and system transformations
  What does the course offer ?

This course introduces all the main TRIZ tools : Ideality and IFR, Problem formulation and Functional Analysis, Use of 40 Principles to solve contradictions, Use of S-curves and Technology Evolution trends, and Use of extended knowledge-bases. The introduction to each TRIZ tool is followed by a few examples from the knowledge (patent) database and at least one case-study where a real problem has been solved by applying the particular TRIZ tool.

TRIZ methodology will be compared with other Creative and Innovative methods like Brainstorming, Lateral Thinking, Neuro-Lingual-Programming, Mind-mapping, etc. for their efficiency of overcoming psychological inertia. The role of TRIZ in an innovative design cycle will be discussed. The synergy between TRIZ, QFD and Taguchi methods will be highlighted.
