@QAI

TRIZTRIZProjects frequently reach a point where theanalysis is completed and the team is at a point

where it is unclear where they need to go forresolution. This applies not only to projects butto problem solving, root cause analysis, or

even Six Sigma (upon completion of theanalysis phase). The project team must becreative in order to determine what to do next.

TRIZ minimizes the chance of unpredictableand unrepeatable results that are associatedwith brainstorming or brainwriting.

@QAI

TRIZTRIZ

TRIZ is based on the idea that many of

the underlying root problems thatengineers face today contain elementsthat have already been solved

(approximately 90%), often in acompletely different industry, for a

totally unrelated situation, that uses anentirely different technology.

The most important recognition is thattechnical systems evolve

Which evolves towards theincrease in ideality

By overcoming Contradictions

Achieved primarily with theminimal introduction of

T.R.I.Z. (Trez or trees)

Theoria Resheneyva Isobretatelskehuh ZadachTheory of Inventive Problem Solving

Developed after WWII (1946) by GenrichAtschuller (1926-1998), a Russian inventor andnaval officer. He was sent to the Siberian Gulag

camp by Stalin for thinking too much. He wasreleased from prison after Stalins death.

Based on a theory that there are universal

principles of inventive and creativity. TRIZ is structured method that can be used to

rapidly generate plausible concepts that solveproblems in technical and non-technical domains.


11/27

@QAI

Altschuller / T.R.I.Z. Started with 400,000 patients, today it

includes the study of more than 2.5 millionpatients.

Altschuller discovery:

Each innovative patient solves a technicalproblem, but across domains, there are commonsolutions. These solutions were boiled down to 40principles.

Inventive problems often carry with them inherentcontradictions. (e.g. stronger, but heavier)

Anyone can use this knowledge and methodologyto solve problems.

Resources are often idle during problem solving.

@QAI

Why TRIZ ?

Simply stated, we need to createinnovative products and services to

remain competitive ! We need to significantly improve the

engineers ability to quickly solve difficult and

seemingly impossible engineering problemswhich often lead to next generationinnovative products.

Altschuller Contradiction Matrix The 40 Inventive Principles can be utilized to solve

problems but unfortunately, fixing one problem oftenresults in creating another problem.Examples:

Companies buy other companies to grow andstrengthen themselves. This often results in acompany disorganized and less stable.

Coffee should be hot for enjoyable drinking

but cool enough to prevent burning thedrinker.Bandwidth increases (Good) but requires more

power (bad)

Training increases competence (Good) butrequires employees to be away from their jobresponsibilities (bad).

These contradictions can be resolved by applying theContradiction Principles in a Contradiction Matrix.

@QAI

Altschuller Contradiction Matrix

As you can see from the examples onthe previous slide there are twocategories of contradictions.

1. Technical contradictions are based onclassical engineering of trade-offs. The

desired state can not be obtain becausethere is a barrier in the system.

2. Physical contradictions (Inherent) are

situations in which one object or systemcontradicts the requirements of the other.

@QAI

Contradiction Principles1. Weight (of object in motion)

2. Weight (of stationary object)3. Length (of object in motion)

4. Length (of stationary object)

5. Area (of object in motion)

ContradictionsContradictions appear first as a gapbetween demands and supplies. They

are overcome by break-throughinventions. These inventions form the

micro-steps of evolution in technicalsystems. Since the solutions are notknown, creative problem solving is the

method utilized to overcomecontradictions.

Contradiction Matrix

Are a result of Altschullers patent research

The principles are technical characteristics Can be applied throughout the Six Sigma

DMADV process whenever conflicts or

contradictions arise.

It is a large table that link pairs of the

engineering principles (39 X 39 matrix).

Contradiction Matrix

The core process is to drive a physical

contradiction (using the matrix) and solveit with the Separation Principle. Once thephysical contradiction is determined thissolution technique is powerful enough toidentify break-through (innovative)

solutions.

TRIZTRIZ works and is used by large aswell as small organizations on several

levels to solve real, practical everydayproblems. TRIZ is utilized at

companies such as Ford, Motorola,Proctor & Gamble, Eli Lilly, 3M, LGand
