Ideal Final Result
Encyclopedia
Ideal final result is a description of the best possible solution for the problem situation (or contradiction
), regardless of the resources or constraints of the original problem. IFR is one of the basics terms in TRIZ
, a problem solving methodology.
A well-defined IFR helps a problem solver to overcome psychological inertia and reach breakthrough solutions by thinking about the solution in terms of functions, not the intervening problems or needed resources. It focuses on functions needed, not the current process or equipment.
The idea of formulating the IFR is to clearly define the goal of improvement and eliminate rework (solve the right problem initially).

In engineering, a typical IFR is the idea of "perpetual motion" machine. Inventors may not achieve the ideal result (French Academy of Science does not even take the patent applications for it), but striving for this high ideal allowed inventors to create numerous mechanisms with minimum friction, thus moving technology forward. In the field of education, the concept of IFR helped to create the models of Ideal Education, Ideal Learner, and Ideal Teacher, all of which paved the way to Creative Pedagogy

Contradiction
In classical logic, a contradiction consists of a logical incompatibility between two or more propositions. It occurs when the propositions, taken together, yield two conclusions which form the logical, usually opposite inversions of each other...

Function (mathematics)
In mathematics, a function associates one quantity, the argument of the function, also known as the input, with another quantity, the value of the function, also known as the output. A function assigns exactly one output to each input. The argument and the value may be real numbers, but they can...
