TRIZ 40 Principles

Creative Solving of Engineering Problems and Inventing New Products

By: Genrich Altshuller

Entrepreneurial Creativity (Ten3 Mini-course)

TRIZ ("The theory of inventor's problem solving")  was developed by a Soviet engineer and researcher Genrich Altshuller and his colleagues starting in 1946. It has been evolving ever since. Today, TRIZ is a methodology, tool set, knowledge base, and model-based technology for generating innovative ideas and solutions for problem solving. TRIZ provides tools and methods for use in problem formulation, system analysis, failure analysis, and patterns of system evolution. In contrast to random idea generation techniques such as brainstorming, TRIZ aims to create an algorithmic approach to the invention of new systems, and the refinement of old systems.

31

Porous materials

Make an object porous or add porous elements (inserts, coatings, etc.).

If an object is already porous, use the pores to introduce a useful substance or function.

32

Color changes

Change the color of an object or its external environment.

Change the transparency of an object or its external environment.

33

Homogeneity

Make objects interacting with a given object of the same material (or material with identical properties).

34

Discarding and recovering

Make portions of an object that have fulfilled their functions go away (discard by dissolving, evaporating, etc.) or modify these directly during operation.

Conversely, restore consumable parts of an object directly in operation.

35

Parameter changes

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.

36

Phase transitions

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

37

Thermal expansion

Use thermal expansion (or contraction) of materials.

If thermal expansion is being used, use multiple materials with different coefficients of thermal expansion.

38

Strong oxidants

Replace common air with oxygen-enriched air.

Replace enriched air with pure oxygen.

Expose air or oxygen to ionizing radiation.

Use ionized oxygen.

Replace ozonized (or ionized) oxygen with ozone.

39

Inert atmosphere

Replace a normal environment with an inert one.

Add neutral parts, or inert additives to an object.

40

Composite materials

Change from uniform to composite (multiple) materials.
