Modular Fieldbus Bridge Integrating Smart Functions Without Length Increase
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modular fieldbus systems for pneumatic valve manifolds lack the ability to integrate additional smart and intelligent components without increasing the length of the module bank, limiting the addition of features like Wi-Fi transmission and automatic recovery modules due to spatial constraints.
Innovation Solution
A modular electrical fieldbus system where functional modules with internal smart or intelligent devices replace passive bridge elements, providing electrical and mechanical connections between modules without extending the bank's length, incorporating wireless gateways or automatic recovery modules with non-volatile memory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If passive bridge elements are used to connect modules, then electrical connection between modules is achieved, but additional smart functions cannot be integrated and the mounting track length is wasted
Solution Approach 1:
The bridge element is transformed from a single-function passive connector into a multi-functional component that simultaneously provides electrical connection, mechanical support, and hosts smart/intelligent devices. This allows the same component to fulfill multiple roles: connecting modules electrically, providing structural support, and enabling advanced functions like wireless communication or automatic recovery without requiring additional components or space.
2Adaptability or versatility
If the mounting track length is increased to accommodate additional components, then more smart functions can be added, but the spatial constraints of the installation cabinet are exceeded
Solution Approach 1:
Multiple functions that would traditionally require separate components are merged into a single bridge element. Instead of having separate passive connectors and separate smart function modules that would consume additional mounting track space, the smart functions are integrated directly into the bridge element itself, allowing multiple capabilities to coexist within the same physical footprint.
3Adaptability or versatility
If functional modules are stacked onto original modules, then smart functions are added, but the length of the module field bus bank increases
Solution Approach 1:
The smart functional devices are nested within the bridge element structure rather than being added as external extensions. The bridge element serves as a container or housing that incorporates the smart functions internally, similar to how nested dolls place smaller objects within larger ones. This nesting approach allows functional expansion without increasing the overall external dimensions of the module bank.

AI summary
A modular electrical bus system for a valve manifold has a communication module, a valve driver module, and a plurality of I/O modules each having a plurality of I/O fittings being both electrically and mechanically connectable together via a bridge member connecting adjacent modules. The bridge member has a housing with an interior for housing electronic components for memory storage or Wi-fi reception and transmission that is operably connected to a complementary electrical fitting constructed to be connected to an electrical fitting of a module of said electrical fieldbus system without adding extra length to said bank of modules of said electrical fieldbus system.
