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 support system with adjustable cable management brackets, featuring a fixed portion and a rotatable portion that allows for module insertion and removal without disturbing connected cables, optimized for various configurations to ensure independent access to all modules while maintaining cable routing integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cable management brackets are fixed in position, then cable routing is stable and organized, but module insertion and removal is blocked by cable interference
Solution Approach 1:
The cable management bracket incorporates a rotatable portion that can pivot between a first position (for module access) and a second position (for cable management). This dynamic adjustment allows the bracket to adapt its configuration based on operational needs, resolving the contradiction between ease of module operation and cable routing reliability.
Solution Approach 2:
The bracket is divided into a fixed portion and a rotatable portion, allowing independent movement of the cable management section while maintaining the structural stability of the anchored section. This segmentation enables the cable management functionality to move independently without affecting the overall bracket stability or cable connections.
2Productivity
If packaging density of networking interconnects is increased, then bandwidth is improved, but cable management complexity increases
Solution Approach 1:
The rotatable bracket provides a dynamic cable management solution that can adapt to high-density interconnect configurations. By allowing the bracket to rotate into different positions, the system can manage complex cable routing requirements arising from increased packaging density without adding permanent structural complexity.
Solution Approach 2:
The bracket design serves multiple functions: it provides structural support, organizes cables, and enables module access. This multi-functionality addresses cable management challenges in high-density systems without requiring separate dedicated components for each function, thereby managing complexity while supporting high bandwidth requirements.
3Ease of operation
If rotatable portion is added to bracket, then module access is enabled, but bracket structure becomes more complex
Solution Approach 1:
The bracket is segmented into a fixed portion and a rotatable portion, where only the necessary cable management section is made movable. This selective segmentation adds minimal complexity by limiting rotation capability to specific portions while maintaining structural simplicity in the anchored sections.
Solution Approach 2:
The rotatable bracket combines the functions of structural support and cable management in a single integrated component. By merging these functions rather than using separate components, the design achieves module accessibility without proportionally increasing overall device complexity.
