Mistakes to avoid
Formulating a TRIZ contradiction

We often see a return to good old-fashioned cost-quality-delay reflexes. It's important to adopt an inventive logic, where the reasons for the evolution of the technical system under study are not necessarily immediate profit, but what can legitimately be estimated for the future of the object. When choosing a contradiction, don't necessarily focus on the parameters that seem important to you, but on those that hinder the object's evolution towards its ideal.
