THEORY 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:
1. Problem definition: find the functional analogy
3. Compare biological and TRIZ-recommended solutions.
2. Problem understanding: uncover contradictions.
4. Build a bridge from nature to technology- try different
combinations of natural and technological advice.
1. What is the problem?
How to climb a tree?
How to grip on ice?
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?

Nature’s solution principles:
Engineering solutions
(BIOTRIZ Matrix recommends)
(TRIZ matrix recommends)
№1
“Segmentation:”
№ 1 “Segmentation” : Divide paw on several pads
№8 “Anti-Weight”
№ 3 “Local quality” : Develop sharpness locally
№18 “Mechanical vibration”
№17 “Another dimension”: Make contact surface 3D
№37 “Thermal expansion”
Technical Contradiction to resolve: How to walk on points when you are heavy?
(To reduce contact surface area without loosing weight - field 5/1 in TRIZ Matrix)
№19 “Periodic action”:
№15 “Dynamics”
Retracted claw
Extended claw
№ 2 “Taking out”
№4 “Asymmetry”
№17 “Another dimension”
№29 “Pneumatics and hydraulics”
Technical Contradiction to resolve: How to be sharp only when it is necessary?
(To reduce surface contact area without loosing the adaptability and composition stability - fields 5/35 and 5/13 in TRIZ Matrix)
№15 “Dynamics”
№30 “Flexible shells and thin films”
№2 “Taking out”
№11 “Prior cushioning”
№13 “The other way round”
№39 “Inert atmosphere”
№19 “Periodic action”
№15 “Dynamics”
3. Compare biological and engineering solutions
1, 15, 17
Copying natural solutions: ice treads:
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 person’s 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.
