The inventor of TRIZ, Genrich Altshuller, after reviewing nearly 200,000 patent applications, divided the inventions into 5 basic levels from easy to difficult. You can see the ratio of these levels in the total from the graph I have prepared below:
According to this graph, humankind is mostly content with making inventions at simple levels (between levels 1-3).
This humanity developed different problem solving tools for different types of problems. Here are some tools that can be used to solve the constraints that may arise in these levels:
Especially after level 2, as the problems become more complex, the number of trial and errors will increase, therefore the use of certain problem solving tools will make it easier to solve the constraints (quality, function, time, cost) called the Iron Triangle. I will explain the Iron Triangle in my next blog.
