THEORY OF INVENTIVE PROBLEM SOLVING HOW TO MAKE
BIOMIMETIC INVENTIONS
Dr.Olga Bogatyreva, ensob_at_bath.ac.uk
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. 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? (see field 10/1 in TRIZ Matrix)
Engineering solutions (TRIZ matrix recommends)
Natures solution principles (BIOTRIZ Matrix
recommends)
?1 Segmentation ?8 Anti-Weight ?18
Mechanical vibration ?37 Thermal expansion
? 1 Segmentation Divide paw on several
pads ? 3 Local quality Develop sharpness
locally
?17 Another dimension Make contact
surface 3D
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
? 2 Taking out ?4 Asymmetry ?17 Another
dimension ?29 Pneumatics and hydraulics
Extended claw
Retracted claw
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
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.
