You will find a series of online tools on this site absolutely free. The features and functionality of the tools are as good as any commercially available tool.

Oneline Matrix is a Matrix of 39 improving features on the y-axis and 39 worsening features on the x-axis. Each cell represents a contradiction by two different parameters. Each cell consists of some Inventive Principles which are most frequently used to solve that contradiction. When you move the mouse pointer to any principle, it displays the description of that principle.

Popup Matrix is a compact Contradiction Matrix which occupies less space on the screen. When the user moves the mouse pointer to a row it displays an improving parameter, when to a column it displays the worsening parameter. When the user moves the mouse pointer to a cell it displays the contradiction parameters and solving principles.

It is the same classical Matrix as above but very compact and handy.

This tool provides two combo boxes to enter the improving feature and worsening feature. When you feed the feed the features, the software will display you the Inventive Principles with their description and examples.

This tool can be used after using the above Contradiction Matrix or can be used independently substituting the Contradiction Matrix.

This tool provides the details of Principles with examples. Below each Principle there is a tabular list of all contradictions that the principle solves. When we move the mouse over the contradictions, it pops up the description of each contradiction parameter.
This is a reverse tool to Contradiction Matrix. Contradiction Matrix takes us from contradiction to Principles, this tool takes us from Principles to Contradictions. This tool will not be as frequently used as the above two, but will be found very useful in specific cases.
