MethodologyFirst building block of TRIZ.After TRIZ 40 different methods or possibilities for the methodology are defined, which can help systematically thereby (however not to have) from a dead end during a problem solution to come out or a "break-through" to prepare a new idea:

  • Segmenting
      Technical problem: Arrange a system into modules, increase the degree of the partitioning, or lay the object out detachable.
  • Extraction
      Technical problem: Extract a "disturbing" constituent and regard it separately.
  • Local optimization
      Technical problem: Over completely of a homogeneous structure of an object to heterogeneous structure/composition. Different sections of the object take over different functions, optimize each constituent for itself.
  • Asymetrie
      Technical problem: Replace a symmetrical structure by an asymmetrical or increase the degree of the Asymetrie, if it is already asymmetrical.
  • Combination
      Technical problem: Spatial joining and temporal clocks of individual functions.
  • Universality
      Technical problem: A system fulfills different functions.
  • Nesting
      Technical problem: The principle of the Russian dolls: embed an object into another, these if necessary in a third etc....
  • Counterweights
      Technical problem: Kompensatiosmechanismen.
  • Preventing interaction
      Technical problem: Prevent by counter measures an occurring of unwanted effects.
  • Antizipierte effect
      Technical problem: Create conditions, on which the intended effect or the effect intended occurs.
  • Precautionary security
      Technical problem: Compensate weak points by counter measures.
  • Aequipotentialitaet
      Technical problem: Arrange the surrounding field in such a way that the expenditure for the interaction with the object is minimized.
  • Inversion (function reversal)
      Technical problem: Analyze the effect determined by the problem specification and examine the contrary effect.
      See also: Reversal method.
  • Curvature (Nichlinearitaet)
      Technical problem: Where linear items leave themselves by nonlinear erstetzen (e.g. even surfaces by curved, translation movements by rotation); Use from centrifugal energy.
  • Dynamisierung
      Technical problem: Arrange the object or its environment in such a way that it adjusts automatically in all operating conditions to optimal behavior; divide the object into items, which are to each other mobile and can optimally arrange itself; make a static object mobile, adjustable or exchangeable.
  • Part or over fulfilment
      Technical problem: If the desired effect can be attained by hundred percent with difficulty, solve the problem by part or over fulfilment with following correction.
  • Dimension increase
      Technical problem: Go around difficulties of linear arrangements by avoiding in the level, or transition from surface to the Reumgestalt, resolving the simultaneousness by introduction of the temporal dimension; Use of multi-sandwiches instead of single positions; slope the object or brings it in side position.
  • Vibration
      Technical problem: Shift the object in oscillations, the variriere frequency, the nzutze resonant frequency out.
  • Periodicity
      Technical problem: Replace similar to by digital processes; use suggestions for pulse in place or in connection with continuous effect on the system; use a tracing; use the parameters of periodic processes
  • Continuity
      Technical problem: Eliminate downtimes and empty.
  • Rate
      Technical problem: Execute process with so high rate that it is final, before side effects can unfold.
  • From the NOT to the virtue
      Technical problem: Examine negative or breakdown effects on ranges of application.
  • Feedback
      Technical problem: Use feedbacks for the optimization of the behavior; if they are available, modify them or turn around it.
  • Mediation
      Technical problem: Use a mediating Obkejt, in order to transfer or promote the effect; connect the system vorruebergehen with one anderemm one object which can be changed easily.
  • Self maintenance
      Technical problem: Let the object wait themselves and own auxiliary and repair functions to execute; use material- ones and energy "Abfaelle".
  • Copy, visualization
      Technical problem: Use of simple and inexpensive copies in place of a complex, expensive, fragilen or object which can be handled pedantically. Replace an object by an optical copy or an image. Replace visible copies by infrared ones or ultraviolets.
  • One-way components
      Technical problem: Replace expensive objects by cheap one-way products.
  • Substitution of mechanics
      Technical problem: Replacement by optical, acoustic, elektronagnetische and other systems.
  • Pneumatics and hydraulics
      Technical problem: Replace rigid of constituents of an object by a gas or a liquid.
  • Flexible diaphragms or thin films
      Technical problem: Replace tradizionelle constructions by thin-film technology.
  • Por&aumloese materials
      Technical problem: Replace components by porous constituents or add it. If an object is already porous, use the pores with a suitable substance.
  • Color changes
      Technical problem: Change of the color design of an object or its environment; Utilization of transparency. Use, - back or continuing to glow items for the support of the function.
  • Homogeneity
      Technical problem: Select sections to main component-cooperate those with one if possible from the same or a similar material.
  • Rejecting and recovering
      Technical problem: After a section fulfilled its function and is useless, remove or modify it (to reject, resolve, evaporate). Replace directly used up or worn sections.
  • Changes in status
      Technical problem: Change physical or chemical parameters (temperature, density distribution, viscosity).
  • Phasenuebergaegnge
      Technical problem: Use effects, which are based on phase transitions of a material.
  • Thermal expansion
      Technical problem: Use a material that when heating up expands or pulls together; or different materials with different coefficients of expansion.
  • Strong Oxidantien
      Technical problem: Treat the object with compressed or oxygen-enriched air, pure oxygen or ozone.
  • Inert environment
      Technical problem: Isolate the system or embed it into a protected environment. Execute a process in the Vakkum.
  • Material network
      Technical problem: Replace homogeneous Matierial by a composite material.
  • Necessarily
