Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for linking signals between multiple printed circuit board assemblies become complex and difficult to manage when dealing with three or more boards, as they require numerous cables or a linking board, hindering efficient communication and servicing.
Innovation Solution
A printed circuit board system comprising a plurality of PCB assemblies and a connecting module that provides electrical and signal communications between each assembly, with the connecting module being on different planes relative to at least one PCB assembly, allowing for efficient communication and easy servicing by reducing the need for multiple cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables or a linking board are used to link signals between multiple printed circuit board assemblies, then electrical communication between boards is established, but the system complexity and difficulty of servicing increase significantly when dealing with three or more boards
Solution Approach 1:
The patent merges multiple cable connections into a single bus bar structure. Instead of using individual cables to connect each PCB assembly to every other board, a single bus bar provides a common electrical connection point for all assemblies, significantly reducing the number of separate connection elements required.
Solution Approach 2:
The bus bar serves multiple functions simultaneously: it provides electrical connection, mechanical support, and signal distribution to multiple PCB assemblies. This multi-functional element replaces what would otherwise require separate cables, mounting structures, and connection mechanisms for each board.
2Reliability
If traditional cable-based methods are used to connect multiple printed circuit board assemblies, then electrical communication is achieved, but servicing time and assembly complexity increase
Solution Approach 1:
The system segments the PCB assemblies into modular units that can be independently removed and installed. Each assembly connects to the bus bar through standardized interfaces, allowing individual boards to be serviced without affecting other assemblies or requiring disconnection of multiple cables.
Solution Approach 2:
The connection system allows for dynamic addition and removal of PCB assemblies during operation. The bus bar design enables assemblies to be quickly connected or disconnected without requiring system shutdown or complex reconfiguration, facilitating hot-swapping and rapid servicing.
3Adaptability or versatility
If numerous cables are used to link signals between three or more printed circuit board assemblies, then complete electrical connectivity is achieved, but the difficulty of linking and managing connections increases
Solution Approach 1:
The bus bar acts as an intermediary element between multiple PCB assemblies. Instead of requiring direct cable connections between each pair of boards, the bus bar mediates all electrical connections, providing a central hub that simplifies the connection topology and makes routing and management much easier.
