Methodology 
ARIZ is an algorithm or a step procedure for the solution of complex or difficult invention functions. (here in a ziehmlich early Fassumg, sucked. Ariz61)
 Analytic phase
 Define the problem
 Describe the ideal final result (IER)
 Define contradictions, which oppose the implementation of the IER
 Analyze origin and causes of the contradictions
 Define conditions for the overcoming of the contradictions
 Operational phase
 Check all possible modifications of the parameters and technical Charakterisitk
 Check the possibility of the allocation into unanhaengige subsystems:
 Isolate a "weak" and/or a "necessary and sufficient" subsystem
 Divide the object into homogeneous and/or functiondifferentiated subsystems
 Check possible modifications in the respective surrounding field of the object and his parameters
 Arrange the object surrounding field into sections with different characteristics
 Use the Externalitaeten for the execution of desired functions
 Check possible modifications of procedures in interaction with the given technique
 Examine the linkage from before independent technical systems to a functioning total system
 Remove a procedure and transfer his functions to another
 Increase the number of simultaneously running process steps (e.g. with a surface by utilization of the free rear side of this surface)
 Examine examples from other branches of science, technique and economics, how available conflicting aims were solved in other disciplines
 Turn for output question back and more generally formulates the conditions or changes to one for a more familiar task, if the virangegangenen steps remained without result
 Synthetic phase
 Change the shape of the regarded (technical) system
 Change the other procedures, which are connected with the regarded system
 Change muddled with the application of the regarded technique
 Check the application of a found principle for the solution of another (technical) problem
