Optical Network Terminal Bracket with Cable Spool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fiber optic cables are prone to damage during installation due to crimps and sharp bends, and existing solutions lack effective cable management and protection features, leading to failures and the need for costly repolishing of ends.
Innovation Solution
A bracket for optical network terminals with integrated cable management features, including fiber cable spools and a protective cover, that prevents crimps and sharp bends by storing excess cable within its bend tolerance limits and securing the terminal to a wall, while also shielding the cable from accidental contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fiber optic cable is installed without proper cable management, then installation is simpler and faster, but the cable is prone to damage from crimps and sharp bends
Solution Approach 1:
The bracket is pre-configured with cable spools and routing channels that guide the fiber optic cable through predetermined paths with appropriate bend radii. The cable spools are positioned to automatically maintain proper cable tension and routing during installation, eliminating the need for manual cable management adjustments and preventing damage before it can occur.
Solution Approach 2:
The bracket serves as an intermediary device between the cable entry point and the optical network terminal. It provides a structured interface with cable spools, routing channels, and tensioning mechanisms that mediate the cable installation process, ensuring proper cable handling and routing while simplifying the overall installation procedure.
2Volume of stationary object
If excess fiber optic cable is stored without proper structure, then space is saved, but the cable exceeds bend tolerance and becomes damaged
Solution Approach 1:
The cable spools are designed with curved surfaces that guide the fiber optic cable along smooth arcs with radii exceeding the minimum bend tolerance. The routing channels within the bracket also feature curved transitions rather than sharp angles, ensuring that excess cable is stored in a compact manner while maintaining proper bend geometry throughout the entire cable path.
3Device complexity
If the fiber optic cable is exposed and accessible, then cable management is simpler, but consumer contact may cause damage or interference
Solution Approach 1:
The bracket incorporates nested protective structures where cable spools are positioned within recessed areas, routing channels are integrated into the bracket body, and cable pathways are enclosed within protective housings. This nested arrangement protects the fiber optic cable from accidental contact while maintaining an organized, space-efficient configuration that does not significantly increase device complexity.
4Productivity
If the optical network terminal is mounted without secure attachment, then installation is faster, but the terminal may become loose or disconnected
Solution Approach 1:
The bracket integrates multiple functions into a single unified structure: cable routing channels, cable spool mounting, terminal securing mechanisms, and protective housing are all combined in one component. This merging allows the installer to secure the terminal with proper positioning and stability while simultaneously establishing cable routing and protection, improving installation efficiency without compromising terminal stability.
