Rotatable Cable Management Bracket for OIR Module Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modular electronic systems face challenges in effective cable management, particularly during Online Insertion and Removal (OIR) processes, where cable routing interferes with module access, and stringent guidelines must be followed to maintain cable bend radius and prevent mixing of optical and electrical cables.
Innovation Solution
A cable management bracket system with a fixed and rotatable portion that allows for independent cable routing and module access without disturbing existing cable configurations, featuring adjustable features like rotatable brackets, clips, and locking mechanisms to align with module ports and maintain cable orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cable management is implemented with fixed routing structures, then cable organization is improved, but module access during OIR operations is hindered
Solution Approach 1:
The cable management bracket incorporates a rotatable portion that can rotate between a first position for cable support and a second position for module access. This dynamic mechanism allows the bracket to adapt its configuration based on operational requirements, resolving the contradiction between fixed cable organization and flexible module access during OIR operations.
Solution Approach 2:
The bracket is divided into a fixed portion and a rotatable portion that can independently move. This segmentation allows the fixed portion to maintain cable routing stability while the rotatable portion provides access pathways for module insertion and removal, addressing both cable organization and module access requirements simultaneously.
2Reliability
If cable routing is constrained to maintain bend radius, then cable integrity is improved, but cable management flexibility is reduced
Solution Approach 1:
The rotatable bracket mechanism dynamically adjusts cable routing paths while maintaining appropriate bend radii. When the bracket rotates between positions, it guides cables through controlled movement that preserves minimum bend radius requirements, ensuring cable integrity while providing the flexibility needed for different module configurations and access scenarios.
3Reliability
If separate cable management systems are used for optical and electrical cables, then cable separation is improved, but device complexity increases
Solution Approach 1:
The cable management bracket is designed as a universal component that can manage both optical and electrical cables within a single integrated structure. The rotatable mechanism and support features apply to all cable types, eliminating the need for separate management systems while maintaining proper separation and organization of different cable types through appropriate positioning and routing paths.
4Stability of the object's composition
If existing cable configurations are preserved during OIR, then cable routing stability is improved, but module replacement efficiency is reduced
Solution Approach 1:
The rotatable bracket enables rapid reconfiguration of cable access paths during module replacement operations. When a module needs to be removed or inserted, the bracket can quickly rotate to provide clear access pathways without requiring cable disconnection or reconfiguration, thus maintaining cable routing stability while significantly improving module replacement efficiency.
Solution Approach 2:
The bracket is pre-positioned and configured to provide both cable support and module access pathways. This preliminary arrangement ensures that cable routing stability is maintained while module replacement can proceed efficiently without requiring intermediate cable management adjustments or reconfigurations during the OIR process.
