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.

Beforehand cushioning

Prepare emergency means beforehand to compensate for the relatively low reliability of an object.



In a potential field, limit position changes.


The other way round

Invert the action(s) used to solve the problem.

Make movable parts (or the external environment) fixed, and fixed parts movable.

Turn the object (or process) 'upside down'.


Spheroidality - Curvature

Instead of using rectilinear parts, surfaces, or forms, use curvilinear ones; move from flat surfaces to spherical ones; from parts shaped as a cube (parallelepiped) to ball-shaped structures.

Use rollers, balls, spirals, domes.

Go from linear to rotary motion, use centrifugal forces.



Allow (or design) the characteristics of an object, external environment, or process to change to be optimal or to find an optimal operating condition.

Divide an object into parts capable of movement relative to each other.

If an object (or process) is rigid or inflexible, make it movable or adaptive.


Partial or excessive actions

If 100 percent of an object is hard to achieve using a given solution method then, by using 'slightly less' or 'slightly more' of the same method, the problem may be considerably easier to solve.


Another dimension

Move an object in two- or three-dimensional space.

Use a multi-story arrangement of objects instead of a single-story arrangement.

Tilt or re-orient the object, lay it on its side.

Use 'another side' of a given area.


Mechanical vibration

Cause an object to oscillate or vibrate.

Increase its frequency (even up to the ultrasonic).

Use an object's resonant frequency.

Use piezoelectric vibrators instead of mechanical ones.

Use combined ultrasonic and electromagnetic field oscillations.


Periodic action

Instead of continuous action, use periodic or pulsating actions.

If an action is already periodic, change the periodic magnitude or frequency.

Use pauses between impulses to perform a different action.


Continuity of useful action

Carry on work continuously; make all prts of an object work at full load, all the time.

Eliminate all idle or intermittent actions or work.
