    History

    Created by: Genrich Altshuller

    When: 1946-Cold War Era

    Where: U.S.S.R

    Why:Genrich was part of

    Invention Inspection division ofSoviet Navy and was imprisoned

    for 6 years.

    How TRIZ Invented

    Genrich Altshullerreviewed 40,000patents and found a common patternbetween them

    Generates ideas for overcoming thecontradiction by choosing between

    multiple options

    Way to eliminate engineering trade-offs

    TRIZ Basics

    Based on the idea that somewhere

    someone else has already solved your

    problem (or close to it)!

    The hard part is now using their solution to

    fix your own.

    TRIZ Basics

    Start by researching similar

    products to troubleshoot your own

    problemUse the patents of similar

    products to compare to your own

    concept

    Contradictions

    1. Technical Contradictions

    2. Physical (Inherent) Contradictions

  • 7/30/2019 Triz(Rishi Raj)

    11/27

    Technical Contradictions

    Basic Engineering Trade-offs

    More of one thing means less of another

    Ex: Want more acceleration (improve) meansa larger engine, cost increases, weight, etc(degrades)

  • 7/30/2019 Triz(Rishi Raj)

    12/27

    Physical (Inherent) Contradictions:

    More of one thing and less of another may be

    needed for a system (i.e. situations in which

    one object or system has contradictory,

    opposite requirements)

    EX: Coffee should be hot (to enjoy), but cold

    so as not to burn

    40 Inventive Principles

    Matrix of Contradictions

  • 7/30/2019 Triz(Rishi Raj)

    14/27

    Matrix of Contradictions

    Composed of a 39X39 matrix

    Rows: -System features you want to improve

    such as Power, Speed, weight, etc

    Columns: -Undesirable features matching that

    of the rows

    Each cell gives principles that have been

    most frequently used to resolve the issue

    Example

    16/27

    Example 1: -

    a problem is that we need a

    device to hold an easily breakable

    part, which has a complex shape.

  • 7/30/2019 Triz(Rishi Raj)

    17/27

    Solution: -

    Use Contradiction Matrix And try to

    Positive effect on vertical column and

    negative effect on row. you will find in

    (10, 30) which narrow down your principal

    Principal find?

    Segmentation

    Mechanical vibration

    Transformation of physical and chemical

    states of an object

    Composite materials

    Theory of Ideality

    Ideality = benefits /(Cost + Harm)

    Ideality is the situation after a particular

    problem has been solved. This ideal

    solution is termed the Ideal Final Result

    (IFR) and is considered in TRIZ toensure that the right problem is solved

    the first time

    S-Field Theory

    The Basic Ideas

    In every technological system one can discern two objects or

    substances, S1 and S2.

    Mechanical

    Acoustic

    Thermal

    Chemical

    Electric

    Magnetic

    Example

    Problem: - Finding Refrigerant Leaks

    S1 represents the maintenance worker

    S2 the leak

    Field(f1) the light

    (an optical field)

  • 7/30/2019 Triz(Rishi Raj)

    23/27

    Solution :

    Add a small amount of a fluorescentsubstance, S3, to the refrigerant, and to

    look for it using ultraviolet light
