Solution Overview

Problem

The existing methods for transforming conventional optical distribution networks (ODNs) into intelligent optical distribution networks (IODNs) require service interruption and are costly, causing inconvenience to users due to the need to replace trays.

Innovation Solution

A cable distribution device for optical networks that includes a tray with multiple interfaces, attachment plates, a circuit board, and adapters, allowing the installation of a cable distribution structure for IODNs without replacing the tray, thereby enabling transformation of ODNs into IODNs without interrupting optical fiber transmission services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a newly developed intelligent tray is used to replace a tray in an existing ODN, then the ODN can be transformed into an intelligent optical distribution network, but the service must be interrupted during transformation, causing complex operation and high costs

Engineering Contradiction:

Improveintelligent network capabilityVSAvoidservice continuity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The invention divides the intelligent optical distribution system into two independent parts: the existing tray structure and the new intelligent cable distribution structure. The intelligent cable distribution structure is a separate module that can be installed on top of the existing tray without replacing it, allowing the tray to remain in place while adding intelligent functionality through modular attachment.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The intelligent cable distribution structure is nested on the existing tray structure. The attachment plates are installed on the tray, and the intelligent cable distribution components are mounted on these attachment plates, creating a nested configuration where the new intelligent system is positioned on top of the conventional tray without removing or replacing the original tray.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Adaptability or versatility

If a newly developed intelligent tray is used to replace a tray in an existing ODN, then the ODN can be transformed into an intelligent optical distribution network, but the transformation costs are high

Engineering Contradiction:

Improveintelligent network capabilityVSAvoidtransformation cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The attachment plates are designed with universal compatibility to fit standard tray interfaces. The intelligent cable distribution structure can be installed on existing trays from different manufacturers by utilizing the standard interface specifications, making the transformation solution universally applicable and reducing customization costs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If attachment plates are installed on the tray, then the intelligent cable distribution structure can be mounted without replacing the tray, but the attachment plate must be securely fixed to prevent displacement

Engineering Contradiction:

Improveinstallation convenienceVSAvoidattachment stability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The attachment plates are pre-installed on the tray before the intelligent cable distribution structure is mounted. The pre-installation process includes securing the attachment plates to the tray using fastening mechanisms, ensuring that the foundation is prepared and stable before the main intelligent components are attached, thereby preventing displacement during operation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The attachment plates incorporate curved or rounded interface features that match the tray's interface geometry. The rounded corners and curved edges of the attachment plates fit into corresponding recesses on the tray, providing mechanical interlocking that prevents displacement while maintaining secure fixation.

Inventive Principle:

Principle #14Spheroidality (Curvature)
