B-CUBE

Abstract

The terms Function, Behaviour, Structure have been used since the 1990s in order to define a framework where a system’s functionality can be modelled and represented: the FBS framework. Within this framework, Function represents the functions of the system, Structure represents the physical elements, and Behaviour acts relating them both. Several common deficiencies have been found from the study of several works carried out on the field of functional design, such as the lack of an integrated approach or a stable conceptual framework. Likewise, it has been proven that the process of functional design automation exhibits problems as well with regard to taxonomies or linking to CAI (Computer Aided Inventing) programs. Moreover, subjectivity from the designer when he interprets the behaviours need to be considered. In this article we present a new approach to functional design through FBS framework, able to solve, a priori, the aforementioned problems. This approach, called B-Cube, proposes a three dimensional scheme that uses definitions as Behaviours concepts. The key of this approach is that a Behaviour is not defined with a word or a taxon, which could cause ambiguity and misinterpretation, but rather defined as a three dimensional vector (X, Y, Z), set by its characteristics and qualities.
