Optical Fiber Distribution Frame Modular Tray Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical fiber distribution frames are inconvenient for maintenance due to the insecure retention of optical fibers, requiring bundling and rebundling when adding or removing fibers, which complicates the arrangement and positioning of optical fibers.
Innovation Solution
The optical fiber distribution frame features a casing unit with stacked tray units, each equipped with partition plates, inner guiding rails, mounting seats, and cable management members. The tray units are designed for flexible movement and the cable management members provide a secure and easy-to-use mechanism for managing optical fibers, allowing for individual fiber removal and addition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If optical fibers are bundled together using cable ties, then multiple optical fibers can be arranged in a fiber bundle, but the optical fibers are not securely retained and maintenance becomes inconvenient
Solution Approach 1:
The patent divides the fiber bundle management into independent modular units - individual fiber holders are spaced along the guide rail, allowing each fiber to be independently positioned and secured without affecting others. This segmentation enables easy maintenance while maintaining organized bundle arrangement.
Solution Approach 2:
The patent introduces an intermediary structure - a guide rail with mounting seats that acts as a mediator between the fiber bundle and the distribution frame. This intermediary provides secure retention through multiple fixed points while maintaining the bundled arrangement, resolving the contradiction between secure retention and ease of maintenance.
2Ease of manufacture
If optical fibers are bundled together, then fibers can be arranged in groups, but removing or adding individual fibers requires untying and retying the entire bundle
Solution Approach 1:
The fiber holders are segmented and independently mounted on the guide rail at specific intervals. This allows individual fibers to be accessed, removed, or added by simply detaching or attaching to a single holder rather than manipulating the entire bundle, greatly facilitating maintenance while preserving organized arrangement.
Solution Approach 2:
The mounting seats on the guide rail are designed to allow dynamic adjustment and repositioning of fiber holders. This enables flexible reconfiguration of fiber positions during maintenance operations without requiring complete disassembly, making the system adaptable to maintenance needs while maintaining structured organization.
3Ease of manufacture
If conventional cable ties are used to bind optical fibers, then fibers can be tied into a bundle, but the bundle is not securely retained on the distribution frame
Solution Approach 1:
The guide rail serves as an intermediary structure that provides multiple secure attachment points for fiber holders. This intermediary mechanism transforms the simple cable tie binding into a multi-point secured system, significantly improving retention reliability while maintaining the ease of fiber bundling arrangement.
Solution Approach 2:
Instead of relying on a single cable tie for retention, the patent segments the retention function across multiple fiber holders mounted at intervals along the guide rail. This distributed retention system provides superior security and stability while preserving the organized bundle structure.

AI summary
An optical fiber distribution frame includes a casing and a plurality of tray units disposed in the casing. Each tray unit includes a partition plate, a plurality of inner guiding rails disposed on the partition plate, a plurality of mounting seats each removably disposed between adjacent two of the inner guiding rails, and a plurality of cable management members disposed respectively in front of the inner guiding rails and each including a lower clamp portion fixed to the partition plate, and an upper clamp portion cooperating with the lower clamp portion to define a cable accommodating space, having one end that cooperates with one end of the lower clamp portion to define an open slot in spatial communication with the cable accommodating space, and operable to adjust a dimension of the open slot to allow or prevent removal of optical fibers from the cable accommodating space.
