Compact Aerial Splicebox with Nested Fiber Trays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optic fiber spliceboxes are cumbersome, difficult to open and close, and lack efficient protection against weather, leading to increased user activation time and risk of rework due to their large size and complex internal architecture, which is not suitable for the demands of high-density urban telecom networks and FTTx installations.
Innovation Solution
A compact aerial splicebox with a non-electricity conductive design featuring a base with peripheral windows and a hinged cover, a U-section belt for airtight closure, and a ring-shaped handle for easy operation, along with a sealing element and connector trays to simplify optic cable and drop cable management, reducing the size and enhancing accessibility and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a larger splicebox is used to accommodate more optic fibers, then the capacity to handle high-density fiber connections is improved, but the device size and installation complexity increase
Solution Approach 1:
The patent implements nested trays within the splicebox structure, where multiple fiber management trays are arranged in a nested configuration. This allows a high number of optic fibers to be organized and accommodated within a compact volume, effectively resolving the contradiction between fiber capacity and device size.
Solution Approach 2:
The patent utilizes three-dimensional space optimization by arranging fiber trays in vertical and horizontal layers, maximizing the use of available internal volume. This dimensional organization allows dense fiber accommodation without increasing the external footprint of the splicebox.
2Reliability
If a more complex internal architecture is used to protect and organize fibers, then the safety and organization of fiber connections are improved, but the ease of operation and installation time are worsened
Solution Approach 1:
The patent divides the internal structure into segmented trays and compartments, each designed for specific functions such as fiber splicing, protection, and routing. This segmentation provides systematic organization that enhances connection safety while maintaining ease of access for activation operations.
Solution Approach 2:
The splicebox is pre-configured with organized trays, protection sleeves, and routing guides during manufacturing. This preliminary preparation reduces on-site installation complexity and activation time, as the protective and organizational structures are already in place rather than requiring field assembly.
3Adaptability or versatility
If a generic splicebox design is used for both splice points and user activation points, then the versatility is improved, but the ease of operation and safety for specific activation tasks are worsened
Solution Approach 1:
The patent designs a universal splicebox platform that can be configured for both splice points and user activation points through modular tray arrangements. The same basic structure serves multiple functions, but with optimized internal configurations that facilitate efficient activation operations when equipped with appropriate trays and organization features.
