ABSTRACT

The gist of tactical TRIZ it is this: You start with your particular problem, or barrier to innovation. In TRIZ terms, such problems are called contradictions, which are either physical or technical in nature.1 A physical contradiction is when one element of a system conflicts with itself, like when you need the temperature of the water to be both hot and cold to satisfy different design requirements. A technical contradiction is when two different elements of a system conflict with each other, like when you need the temperature of the water to be hot, but making it hot then interferes with some other functional requirement. In other words, as one element improves, the other degrades.
