History of TRIZ

• 1926 15 October • 1940 First Invention (13-year-old) • 1946 Military serves in Patent department• 1946 Start of TRIZ development (20yr)• 1949 Two Grand Prix in inventors competition (23yr), Letter to Stalin, Arrest

• 1956 Freedom, first publication in journal• 1958 Journalist and Science Fiction• 1961 First book about TRIZ• 1971 Lecture at University in Baku• 1974 Publication Abroad (Japan) • 1981 More than 300 school in USSR• TRIZCON held & AI established in USA

Contradiction

• 1946 ~ 1960, Altshuller researched “Contradiction”

Problem Solutionscalled “Inventive” (Level 3 and 4)

OvercomingContradiction

Breakthrough

The typical engineering approach is to compromise, but that approach does not lead to an invention. An Invention overcomes the contradiction.

Two Kinds ofContradiction

TechnicalContradiction


Airplane : Speed , Weight .

Airplane : Landing Wheels must Exist, must not Exist.

(by the powerful engine) (by the larger weight of engine)

(for landing on earth) (for an air resistance at flying)

Chemical : Speed , Quality . (by temperature increase) (undesired reaction also starts)reaction

(Generally, as soon as an engineer solve one problem, another unexpected harmful results happen)

(Generally, by one reason, an engineer must choose an action. But simultaneously an engineer must choose count-action by another reason )

Bicycle : Chain must be Rigid and Flexible.

(to transfer big force) (for circular movement)

divide an object into independent partsmake an object easy to disassembleincrease the degree of fragmentation (or segmentation) of an object

separate an 'interfering' part (or property) from an object, or single out the only necessary part (or property) of an object

change an object`s physical state (e.g. to a gas, liquid, or solid),change the concentration or consistency,change the degree of flexibility,change the temperature.

use phenomena occurring during phase transitions (e.g. volume changes, loss or absorption of heat, etc.).

change from uniform to composite (multiple) materials

Contradiction

Is there any method to use 40 principles with easy ?

Altshuller made standard vocabulary at engineering field as39 Engineering Parameters.





Resource

Contradiction

Recommended principles by Altshuller ; usually 3 or 4 principles among 40 principles





Resource

In every technological system, one can discern two objects or substances, S1 and S2.

[ex : two parts of system the system itself and its product the system and its environment]

These substances interact or communicate through a field, F.

[ex : Mechanical Acoustic Thermal Chemical Electric Magnetic etc]

The relationship between the field and the two substances can be expressed in a Su-Field triangle.

This triangle diagram may be thought of the technological system.It is of course a very simple, abstract model.More detailed models can be made by adding more nodes, linking triangles together, etc.

Su-Field Analysis

• 1956 ~ 1970, Altshuller researched “Resource”





Resource

These diagram can be made more informative by introducing different line symbols for the connections between nodes.

Su-Field Analysis

• 1956 ~ 1970 : Resource

If a Su-Field diagram contains dashed or wavy lines, then the system it represents needs improvement ie, an inventive problem.

The solution to this inventive problem may also be presented by a Su-Field diagram, which would be a modification of the original diagram.

ARIZ

• 1970 ~ 1985, he researched Problem Solving ProcessAttention!ARIZ is a complicated tool. Do not apply it to solve new practical problems without at least for 80 academic hours of preliminary study.

ARIZ Education at SAMSUNG by TRIZ Master Nikolai Khomenko





Resource

ARIZ

• 1970 ~ 1985 : Problem Solving Process

Step 1. Analyzing the Problem

1.1. formulate the mini-problem1.2. define the conflicting elements1.3. describe graphic models for technical contradiction1.4. select a graphic model for further analysis1.5. intensify the conflict1.6. describe the problem model1.7. apply the inventive standards

Step 2. Analyzing the Problem Model2.1. define the operational zone (oz)2.2. define the operational time (ot)2.3. define the substance-field resources (sfr)

Attention!ARIZ is a complicated tool. Do not apply it to solve new practical problems without at least for 80 academic hours of preliminary study.

Step 3. Defining Ideal Final Result (IFR) and Physical Contradiction (PhC)3.1. formulate IFR-13.2. intensify definition of IFR-13.3. Identify the physical contradiction for the macro-level3.4. Identify the physical contradiction for the micro-level3.5. formulate IFR-23.6. apply the inventive standards to resolved physical contradiction

Step 4. Mobilizing and Utilizing of Substance-Field Resources (SFR)4.1. simulation with little creatures4.2. to take a"step back" from IFR4.3. using combination of substance resources4.4. using "void"4.5. using derived resources4.6. using an electrical field4.7. using a field and field-sensitive substance
