Divide the object into independent parts; make it sectional or easy to disassemble; increase the degree of fragmentation

Separate the interfering / harmful part or property from the object; isolate the only necessary part

Change the structure / properties of an object from uniform to non-uniform; let different parts of the object fulfil different functions

Replace symmetrical form with asymmetrical; if already asymmetrical, increase the degree of asymmetry

Bring together identical or similar objects, or operations, in space or in time

Make a part or object perform multiple functions to eliminate other parts

Place one object inside another; pass one part through a cavity of another

Compensate the weight of an object by merging with another that has lift; compensate weight by aerodynamic / hydrodynamic forces

If an action will have both useful and harmful effects, replace it with anti-actions to control harmful effects in advance

Perform the required change of the object (fully or partially) in advance

Prepare emergency means in advance to compensate for relatively low reliability of an object

In a potential field, limit position changes (e.g. change operating conditions to eliminate the need to raise or lower)

Invert the action; make movable parts fixed and fixed parts movable; turn the object upside-down

Replace linear parts with curved; use rollers, balls, spirals; replace linear motion with rotation

Allow characteristics of an object / environment to change to be optimal at each operating stage; make parts mobile relative to each other; if rigid, make it adjustable

If 100% effect is hard, achieve "a little less" or "a little more" — the problem becomes easier

Move from 1D to 2D, from 2D to 3D; use multi-layered assembly; tilt the object; use opposite side of given surface

Make the object oscillate / vibrate; increase frequency to ultrasonic; use resonance

Replace continuous action with periodic / pulsed; change frequency of periodic action; use pauses between impulses

Carry out work continuously, all parts working at full load; eliminate idle / intermittent work

Conduct the process / its stages at high speed

Use harmful factors (especially harmful environmental effects) to obtain a positive effect; amplify a harmful effect to the point where it ceases to be harmful

Introduce feedback; if feedback exists, modify it

Use an intermediary carrier or process; merge temporarily with an easily-removable object

Make the object service itself by performing auxiliary helpful functions; use waste resources / energy / substances

Use simpler & inexpensive copies instead of unavailable / fragile / expensive originals; replace object / process with optical / image copy

Replace an expensive object with a multitude of inexpensive ones, compromising on properties like longevity

Replace a mechanical system with sensory (optical, acoustic, taste, smell); use electric / magnetic / electromagnetic fields; replace static fields with moving / structured ones

Use gas / liquid parts instead of solid (inflatable, hydrostatic, hydroreactive)

Use flexible shells / thin films instead of three-dimensional structures; isolate object from environment with flexible shells

Make object porous or add porous elements; if object is already porous, fill pores in advance with some substance

Change color of an object or its environment; change transparency

Make objects interacting with a given object of the same material (or one with similar properties)

Make portions of the object that have fulfilled their function go away (dissolve, evaporate) or modify them during the work; restore consumable parts directly during operation

Change physical state (gas/liquid/solid); change concentration / density; change flexibility; change temperature

Use phenomena occurring during phase transitions (volume change, heat absorption / release)

Use thermal expansion / contraction of materials; if expansion already used, use multiple materials with different coefficients

Replace common air with oxygen-enriched, then pure oxygen, then ozone

Replace normal environment with inert one; add neutral parts / additives to the object

Change from uniform to composite (multiple) materials
