UNDERSTAND THE «HEARTH» OF THE PROBLEM• PHYSICAL / TECHNICALCONTRADICTIONS
HOW «MATURE» IS MY SYSTEM?• Distance from IFR• ITEMS
HOW DOES MY SYSTEM WORK?• Describe your system/ products
in the most objective way aspossible (“film maker”)
• Describe functions, valueproposition, tangible and intangible features (product specifications)

Applying su-field analysis
• Identify the elements of a system.
• Identify The fields.
• Construct the model.
• After completing these steps, stop to evaluate the completeness and effectiveness of the system. Bring into evidence if some element is missing, some effect is harmful, or not necessary, try to identify what it is.

GENERAL PROBLEM
Solving contradictions means moving towards a general solution for the general problem
Undesired effects, inefficient effectsare often generated by CONTRADICTIONS (conflicts in a system); they represent the general problem

Technical contradictions
Technical contradictions are in a 39 X 39
contradiction matrix
Raffaella Manzini 14
Columns = undesiredcharacteristics
Rows = desired characteristics
Each cell represents a contradiction;
Contradictions can be solved by applying the 40 inventive principles;
the contradiction matrix specifies the principles to be used for each cell

The 40 inventive principles
• The 40 inventive principles represent general solutions drawn from previous inventions
• They represent the principles already used by inventors in their innovation process

Example:
1. Segmentation • Divide an object into independent parts• Make an object easy to disassemble• Increase the degree of an object
