Two Aspects of Function for Technical Systems
Function is very important to understand technical systems. It is defined as ‘specification of an action performed by a material object (Function Carrier) that results in a change or preservation of a value of an attribute of another material object (Object of the Function)’. (from International Association of TRIZ (MATRIZ) definition). This ‘Subject-Action-Object’ function model, which is widely used in innovation process, is ‘action’ oriented definition. Sometimes, however, understanding the function from an outcome perspective and solving problems produce better results.
In this paper author proposes two aspects of function definition (action oriented function and outcome oriented function) to understand technical systems and find creative solutions.
