In modern product design methodologies, designers are increasingly required to combine elements spanning multiple engineering domains, thus blurring the boundaries between engineering disciplines. Functional modeling with the Functional Basis provides the basic tools required to integrate system models at the conceptual level; however, there is a lack of unified rules to address the structure of functional models. This article covers the development of a signal grammar for functional modeling with a Functional Basis. At the conceptual level, signal flows represent the information vital to a proper system operation. Signal flows are explored through their Functional Basis lexicon and primary/carrier flow relationships. A grammar, consisting of morphology and syntax, is presented and applied to a set of electromechanical, component-based building block examples. To further demonstrate the application of signals in functional modeling, an electromechanical product is explored functionally with the application of the signal grammar.
