Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation and wiring of peripheral control posts in railway interlocking and signalling systems are complex, requiring extensive field device wiring and testing, which complicates the process and increases operational difficulties.
Innovation Solution
A peripheral control post design featuring a wiring frame and support/containment frame with interconnectable components, allowing for easy assembly and wiring at the installation site, with multipolar connectors and a bus circuit board system to simplify the connection of control modules to field devices, enabling pre-testing of modules before installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional installation methods are used with separate racks and control modules, then the system can be modular and adaptable, but the installation and wiring operations become particularly complex
Solution Approach 1:
The patent merges the rack structure and control modules into a single integrated peripheral control post assembly. The control modules are pre-mounted on the rack with wiring already connected, creating a unified unit that reduces installation complexity while maintaining modular adaptability through the ability to add or remove complete assemblies.
Solution Approach 2:
The control modules are pre-wired and pre-tested on the rack before being installed at the final location. This preliminary preparation of wiring and connections eliminates the need for complex on-site wiring operations, significantly reducing installation complexity while preserving system modularity.
2Ease of operation
If control modules are pre-installed and wired before final installation, then installation operations are simplified, but transport and handling become more difficult
Solution Approach 1:
The peripheral control post is designed as a segmented assembly where control modules are mounted on a rack that can be divided into manageable sections. This segmentation allows the system to be prepared in advance while maintaining transportability by dividing the overall structure into smaller, more manageable components that can be handled more easily.
3Adaptability or versatility
If extensive wiring is performed on-site, then system configuration can be customized, but installation time and operational difficulty increase
Solution Approach 1:
Standard wiring configurations are prepared in advance during manufacturing, allowing for quick deployment. Custom configurations can still be achieved by selecting different pre-wired modules or making minor adjustments to the pre-prepared connections, significantly reducing on-site wiring time while maintaining configuration flexibility.
Solution Approach 2:
The system uses modular control modules that can be independently selected and configured on the rack. This segmentation allows for easy customization by simply adding, removing, or repositioning complete modules rather than performing extensive custom wiring, thereby reducing installation time while preserving adaptability.
