Fiber Optic Patch Panel Splice Cassette Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber optic patch panels are difficult to install, inspect, and repair individually without causing significant downtime and workload, as they require complete removal from the cabinet and are not easily adaptable to different couplings, leading to time-consuming and complex modifications.
Innovation Solution
The patch panel design features a splice cassette that can be pulled out forwards or backwards, allowing for installation and replacement without dismantling the panel from the cabinet, with a detachable front panel that enables easy access and adaptation to different couplings, and a housing that remains fixed during maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the patch panel is installed in a cabinet with multiple panels, then the network infrastructure is established, but removing or replacing a single panel requires removing all panels in the same area, causing significant downtime and workload
Solution Approach 1:
The patch panel is divided into modular components: a fixed housing that remains in the cabinet, and removable front panels with coupling elements. This segmentation allows individual front panels to be replaced without removing the entire patch panel assembly, enabling maintenance of single panels while others remain operational in the cabinet.
Solution Approach 2:
The front panel is designed to be dynamically removable and replaceable while the housing remains fixed. This dynamic design allows the front panel to be detached for repair or replacement of coupling elements, and reattached to restore functionality, without affecting the stability of the installed patch panel in the cabinet.
2Ease of manufacture
If the front panel is designed for specific coupling types, then the installation is straightforward, but adapting to different couplings requires time-consuming individual modification of the front panel
Solution Approach 1:
The housing is designed with universal features that can accommodate different types of front panels with various coupling elements (SC, LC, ST, FC, etc.). The housing provides a standardized interface and mounting structure that works with multiple coupling types, eliminating the need to modify the housing itself when changing coupling types.
Solution Approach 2:
The front panel is made dynamically replaceable, allowing the system to adapt to different coupling requirements by simply swapping front panels rather than modifying the fixed housing. This dynamic interchangeability provides versatility while maintaining manufacturing simplicity for each front panel type.
3Stability of the object's composition
If the splice cassette is fixed in the housing, then the structure is stable, but installation and repair require complete removal of the patch panel from the cabinet
Solution Approach 1:
The splice cassette is segmented as a separate, movable component within the housing. It can be independently pulled forward or backward for access and manipulation, while the housing remains fixed in the cabinet. This segmentation enables maintenance operations on the splice cassette without requiring removal of the entire patch panel assembly.
Solution Approach 2:
The splice cassette is designed with dynamic movement capability, allowing it to be pulled forward for installation and repair operations, then pushed back into the housing. This dynamic access mechanism maintains the stability of the installed patch panel while enabling easy operation on the splice cassette.
4Ease of operation
If the entire patch panel is removed for cable replacement, then complete access is achieved, but installation time and costs increase significantly
Solution Approach 1:
The patch panel is segmented into a fixed housing and removable front panel. This segmentation allows the front panel to be removed for cable replacement operations while the housing remains installed in the cabinet, significantly reducing the time and effort required compared to removing the entire patch panel assembly.
Solution Approach 2:
The front panel is designed for dynamic removal and reattachment, enabling quick access to the splice cassette and cables for replacement operations. This dynamic access mechanism reduces installation time by allowing localized maintenance without complete panel removal.

AI summary
The panel has a splice cassette (12) displaceably arranged on bottom of a housing and including detachable rear walls (19), where cassette holders (15) are fastened to the rear walls. A perpendicular front wall includes a connector holder for a fiber optic cable plug emerging from the splice cassette. A front plate (26) of the cassette includes recesses corresponding to couplings to be plugged to the plug. A fastening device e.g. screw, fastens the patch panel at a wiring closet and the front plate to the housing. A spring device elastically fixes the cassette in the housing. An independent claim is also included for a method for installing a patch panel. The patch panel is made of metal or plastic.
