3. Local quality
• Change an object’s structure from uniform to nonuniform; change
an external environment (or external influence) from uniform to
nonuniform.
• Make each part of an object function in conditions most suitable for
its operation.
• Make each part of an object fulfill a different and useful function.
4. Asymmetry
• Change the shape of an object from symmetrical to asymmetrical.
• If an object is asymmetrical, increase its degree of asymmetry.
5. Merging
• Bring closer together (or merge) identical or similar objects;
assemble identical or similar parts to perform parallel
operations.
• Make operations contiguous or parallel, and bring them together in
time.
6. Universality
• Make a part or object perform multiple functions to eliminate the
need for other parts.
7. Nested doll
• Place one object inside another; place each object, in turn, inside the
other.
• Make one part pass through a cavity in the other.
8. Antiweight
• To compensate for the weight of an object, merge it with other
objects that provide lift.
• To compensate for the weight of an object, make it interact with the
environment (e.g., use aerodynamic, hydrodynamic, buoyancy, and
other forces).
9. Preliminary antiaction
• If it will be necessary to perform an action with both harmful and
useful effects, this action should be replaced later with antiactions
to control harmful effects.
• Create beforehand stresses in an object that will oppose known
undesirable working stresses later on.
10. Preliminary action
• Perform, before it is needed, the required change of an object (either
fully or partially).
• Prearrange objects so that they can come into action from the most
convenient place without losing time for their delivery.
11. Beforehand cushioning
• Prepare emergency means beforehand to compensate for the rel-
atively low reliability of an object.
