在现代产品设计方法中，越来越多的设计师被要求组合跨越多个工程领域的元素，从而模糊了工程学科之间的界限。具有功能基础的功能建模提供了在概念级别集成系统模型所需的基本工具；但是，缺乏处理功能模型结构的统一规则。本文介绍了用于基于函数的函数建模的信号语法的开发。在概念层面上，信号流代表对系统正常运行至关重要的信息。通过其功能基础词典和初级/载波流关系来探索信号流。提出了一种由词法和句法组成的语法，并将其应用于一组基于组件的机电积木示例。为了进一步说明信号在功能建模中的应用，应用信号文法对某机电产品进行了功能分析。
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.
