To split the chunk of wood, the ax should be heavy, but, at the same time, for ease of handling, the ax should be light. 4 The ideal final result is the solution that resolves the contradiction without compromise. Resources are used to go from the contradiction to as perfect a solution as possible. 5 The seesaw analogy of the ideal final result. Both ends of the plank go up. blow stronger without decreasing the ease of use. The ax marketed by Fiskars solves this problem by using a hollow handle.

This is the first step in finding the real problem and good solutions. We have already said that there are contradictions behind every difficult problem. The concept of a contradiction is very important. Participants in problemsolving training often wish for more help with contradiction analysis, because contradictions are at the core of the most challenging problems.

14 Examples of modeling by nine screens. 3 Nine Screens The location of the problem in time and on the system level can be illustrated by a simple table containing nine screens (sometimes called windows, boxes, the tic-tactoe method, or the system operator). 14). The table helps you to see the problems more clearly and sometimes suggests solutions very directly. In the carrot example, we considered present and past. How about the future? If the carrot row is not thinned, roots will be small. If we can find a use for “minicarrots,” thinning is not needed.
