Pivoting Reel Enclosure for Secure Fiber Cable Payout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fiber optic enclosures face challenges in managing varying lengths of subscriber cables, requiring additional equipment or personnel for installation and leading to cable waste due to the need for unwinding and rewinding, which limits accessibility and efficiency.
Innovation Solution
A reel enclosure with a pivotally coupled base and door or panel that allows the reel to be securely stored and easily accessed, featuring a hinge connection that prevents rotation in closed positions and enables rotation for cable payout, along with raised support structures and teeth mechanisms to manage cable tension and prevent unwinding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spool is recessed within the interior of the enclosure, then the enclosure provides secure storage, but access to the spool becomes limited
Solution Approach 1:
The spool is mounted on a pivotable support structure that can rotate between a first position (recessed within the enclosure for secure storage) and a second position (extended outward for easy access). This dynamic repositioning allows the system to transition between storage and operation modes, resolving the contradiction between secure storage and ease of access.
2Ease of operation
If the spool is provided on the exterior of the enclosure, then access to the spool is improved, but additional equipment or personnel are required
Solution Approach 1:
The pivotable support structure allows the spool to be dynamically positioned between interior and exterior locations. When extended to the exterior, the spool is accessible without additional equipment. When retracted to the interior, the enclosure itself provides the necessary support structure, eliminating the need for external equipment or additional personnel.
3Productivity
If cable is paid out from a spool, then cable deployment is enabled, but unwinding and rewinding creates waste
Solution Approach 1:
The pivotable support structure enables the spool to be extended outward during cable deployment operations, facilitating smooth cable payout without the need for unwinding and rewinding. After deployment, the spool can be retracted back into the enclosure for secure storage, allowing the same cable to be reused for different locations, thereby reducing cable waste.
4Device complexity
If the spool position is fixed, then the structure is simple, but accessibility and rotation control are limited
Solution Approach 1:
The pivotable support structure provides a mechanically simple yet effective solution that enables both positional adjustment (between interior and exterior) and rotational control of the spool. The pivot mechanism itself serves as the actuation system, eliminating the need for complex motors or actuators while providing full accessibility and rotation control when the spool is in the extended position.

AI summary
A reel enclosure includes a base and a door pivotally coupled with the base. The door is movable between a first closed position and a second open position and is configured to hold a reel at an interior surface of the door. The reel is configured to have cable wound thereon. In the first closed position, the base is configured to prevent the reel from rotating relative to the door and the base, and, in the second open position, the door is configured to hold the reel outside of an interior of the base and permit the reel to rotate relative to the door and the base.
