Principles of Space and Time

These principles deal with the physical arrangement of objects and the manipulation of time.

  • Segmentation: Divide into independent parts.
  • “Nested Doll”: Place objects inside each other.
  • Another Dimension: Move object in 2D or 3D space.
  • Skipping: Perform actions at high speed.

Principles of Structure and Form

These principles focus on modifying the shape, structure, and material composition of objects.

  • Local Quality: Vary structure or environment.
  • Asymmetry: Change shape from symmetrical to asymmetrical.
  • Spheroidality - Curvature: Use curves instead of straight lines.
  • Flexible Shells and Thin Films: Use flexible instead of rigid structures.
  • Composite Materials: Use multiple materials.

Principles of Function and Action

This category deals with how objects function and interact, and how actions can be modified for better results.

  • Taking Out: Separate interfering parts or properties. Isolate necessary part.
  • Merging: Combine similar objects or functions.
  • Universality: Make one part perform multiple functions.
  • Preliminary Anti-action: Use counteractions to control harmful effects.
  • Preliminary Action: Pre-change an object.
  • ‘The Other Way Round’: Invert the action.
  • Dynamics: Allow for adaptable characteristics.
  • Partial or Excessive Actions: Use slightly less or more of the solution.
  • Mechanical Vibration: Induce oscillations.
  • Periodic Action: Use periodic instead of continuous action.
  • Continuity of Useful Action: Maintain continuous work.
  • Self-service: Make an object serve itself.
  • Discarding and Recovering: Eliminate or modify used parts.

Principles of Condition and Environment

These principles consider the influence of external conditions and the environment on the problem.

  • Anti-weight: Counteract weight with other objects.
  • Beforehand Cushioning: Prepare emergency measures.
  • Equipotentiality: Limit position changes.
  • “Blessing in Disguise”: Use harmful factors for good.
  • Pneumatics and Hydraulics: Utilize gas and liquid components.
  • Porous Materials: Incorporate porosity.
  • Color Changes: Change object or environment color.
  • Homogeneity: Use same materials for interacting objects.
  • Parameter Changes: Change an object’s physical state.
  • Phase Transitions: Utilize phenomena during phase changes.
  • Thermal Expansion: Utilize expansion or contraction.
  • Strong Oxidants: Use oxygen-enriched air.
  • Inert Atmosphere: Use an inert environment.

Principles of Information and Resources

This group focuses on using information, feedback, and resource management to improve a system.

  • Feedback: Introduce feedback for improvement.
  • ‘Intermediary’: Use an intermediary object or process.
  • Copying: Use simple copies instead of originals.
  • Cheap Short-Living Objects: Replace expensive with multiple cheap objects.
  • Mechanics Substitution: Use electromagnetic fields.
