TRIZ process flow :






2 Key Steps :

A)    Function Analysis
•      Helps to clearly identify the Engineering System.
•      In function analysis we have the Supersystem, System and Subsystem.
•      Subsystem – component within Engineering system.
•      Supersystem – component outside system boundaries. Not designed as a part of the System.
•      System – components interaction between subsystem.


B)    Cause and Effect Chain Analysis
•      Help to identify the fundamental root cause(s).
•      These fundamental root causes are essentially the root causes of Engineering System problem which need to be resolved.

Function can be categorized into two types :
a)      Useful
 i.      Normal
ii.     Insufficient
iii.   Excessive

b)     Harmful

What is TRIZ ?

·         TRIZ is the Russian acronym for the “Theory of Inventive Problem Solving”. ·         It is a systematic problem solving method based on logic and data, not intuition or spontaneous creativity of individuals or groups ·         Developed by Genrich Altshuller and his colleagues from 1946 through to 1985 in the former Union of Soviet Socialist Republics (USSR) ·         It is based on the study of patterns of problems and solutions ·         TRIZ provides repeatability, predictability, and reliability due to its structure and algorithmic approach ·         It improves individual or team’s ability to solve problems Advantage of Triz : ·         Help to find multiple quality ideas in a systematic and efficient manner...

TRIZ Models & Tools :

TRIZ Tool : Structured Problem Solving What is Structured Problem Solving? Structured problem solving provides a systematic approach to advance from the identification of a problem to the solution. Step-by-Step Process 1.     Define Problem : Purpose •        Identify the problem and the importance of working on it Output •        Establish a team •        Develop Problem Statement 2.     Current Solution : Purpose •        Clarify the problem areas as the situation exists today Output •        Create a problem description 3.     Identify Causes : Purpose •        Identify and verify the root causes of the problem Output •        Isolate and verify the root cause of the problem 4.  ...
