Solution Overview

Problem

Traditional fixed or tray drawing type sub-frames and one-way rotating sub-frames in optical fiber distribution systems cannot adapt to changing usage scenarios, leading to increased costs due to the need for multiple sub-frames to meet different rotation requirements.

Innovation Solution

An optical fiber distribution sub-frame design with a detachable bracket system that allows the optical fiber channel tray to be reversed and rotated from one side to the other, enabling both left-hand and right-hand rotation without requiring separate sub-frames, using a bracket connected to the base plate and optical fiber channel tray, with features like sliding buckles, limiting parts, and adapter assemblies for flexible mounting and disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If traditional fixed or tray drawing type sub-frames are used, then structural stability is improved, but adaptability to different usage scenarios deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidadaptability to usage scenarios
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The sub-frame is designed with a rotatable bracket that can be detached and repositioned between different sides of the base plate, transforming a static structure into a dynamic one. The bracket can rotate between first and second positions, allowing the same sub-frame to adapt to different usage scenarios (left-hand or right-hand rotation) while maintaining structural stability through its connection to the base plate and optical fiber channel tray.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If one-way rotating sub-frames are used, then ease of operation for single direction is improved, but versatility for bidirectional rotation deteriorates

Engineering Contradiction:
Improveease of operation for single directionVSAvoidversatility for bidirectional rotation
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The bracket is designed with universal functionality to perform both left-hand and right-hand rotation operations. By providing mounting points on both sides of the base plate and enabling the bracket to detach and reposition, the same sub-frame structure can serve multiple rotational directions, eliminating the need for separate sub-frames for different rotation requirements.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If multiple sub-frames are prepared for different rotation directions, then adaptability to different scenarios is improved, but device complexity and inventory costs worsen

Engineering Contradiction:
Improveadaptability to different scenariosVSAvoiddevice complexity and inventory
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sub-frame is segmented into separable components: a base plate with mounting points, a detachable bracket, and an optical fiber channel tray. This segmentation allows the bracket to be independently repositioned between different sides of the base plate, enabling the same sub-frame to function in multiple rotational configurations without requiring multiple complete sub-frame assemblies, thereby reducing inventory complexity.

Inventive Principle:
Principle #1Segmentation

AI summary

Disclosed are an optical fiber distribution sub-frame and a reversing method, comprising a base plate, two opposite sides of which are each provided with a mounting point position; a bracket, which is detachably mounted at the mounting point position on any side of the base plate; and an optical fiber channel tray, which is hinged to the bracket, and when the bracket is mounted at the mounting point positions on different sides, the optical fiber channel tray is reversed along with the bracket. When the bracket changes position, the optical fiber channel tray connected to the bracket can be reversed together, so that the bracket and the optical fiber channel tray can be replaced from one side of the base plate to the opposite side, and after reversing, the base plate can be replaced from one rotation direction to the other relative to the optical fiber channel tray, therefore, one sub-frame can meet two different usage scenarios of left-hand rotation and right-hand rotation through disassembling and reversing, without the need to prepare two types of sub-frames, reducing stocking inventory, thereby saving time and costs.
