1THEORY OF INVENTIVE PROBLEM SOLVING HOW TO MAKE
BIOMIMETIC INVENTIONS
The Russian system tool TRIZ was developed to
enable engineers to solve problems using alien
disciplines. We are discovering how to include
biology in the system to make Biomimetic
solutions available to technology.
Using TRIZ we designed the algorithm for
transferring ideas from biology into engineering
Problem definition find the functional analogy Problem understanding uncover contradictions. 3. Compare biological and TRIZ-recommended solutions. 4. Build a bridge from nature to technology- try different combinations of natural and technological advice.
1. What is the problem?
How to attach to a surface while moving?
2. Uncover contradictions
Technical Contradiction to resolve How to
increase force on the ground without help of
weight? (see field 10/1 in TRIZ Matrix)

3. Compare biological and engineering solutions
Copying natural solutions ice treads
1, 15, 17
4. Make a Biomimetic solution
The universal wheel can be used as a conditional
one with the tyres inflated for moving under
normal road conditions. But when the surface is
covered with ice or snow and is slippery, the
tyre is deflated until the two lateral discs
provided with teeth will grip the road surface.
Universal wheel possessing traction on both solid
and icy surface
Use intersected principles (1, 15, 17) pure
technical ones (2, 13, 29, 30)
Self-cleaning gripping boots
A boot provided with 2 layers soft elastic and
solid outsole. The hard steel spikes pass through
these layers under the persons weight and grip
the surface. In lifting the foot the elastic
bottom is released and the solid outsole cleans
the spikes of mud or snow.
