Solution Overview

Problem

The existing optical distribution frames (ODFs) are excessively heavy, leading to local downward inclination during installation, which complicates their placement into cabinets and reduces installation efficiency, affecting fiber-optic communication operations.

Innovation Solution

The design incorporates a sliding groove on the optical distribution frame and a convex mounting ear component on the cabinet, allowing the frame to rotate and slide into place, avoiding inclination through a guided mechanism with notches and an inclined surface, and optionally using a macromolecular material to reduce weight.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the optical distribution frame is made heavy-duty to ensure structural strength, then the strength and durability are improved, but the weight increases causing local downward inclination during installation

Engineering Contradiction:
Improvestructural strengthVSAvoidweight of optical distribution frame
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The optical distribution frame is divided into a fixed end (hinged to cabinet) and a movable end (with mounting ear component), allowing the heavy frame to be segmented into stable and mobile portions for easier installation

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting ear component acts as an intermediary between the heavy optical distribution frame and the cabinet, providing a sliding groove mechanism that guides the frame into place without requiring manual lifting of the entire heavy structure

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the optical distribution frame is designed as a cantilever beam structure for stability, then the structural stability is improved, but the ease of installation deteriorates due to local downward inclination

Engineering Contradiction:
Improvestructural stabilityVSAvoidease of installation
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The mounting ear component is designed to slide along a guided groove during installation, transitioning from a movable state (during installation) to a fixed state (after installation), combining ease of operation with structural stability

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The sliding groove mechanism serves as an intermediary that temporarily supports the heavy frame during installation, allowing it to be guided into position without manual manipulation of the entire structure

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the optical distribution frame is made heavy to ensure durability, then the reliability is improved, but the productivity of installation deteriorates

Engineering Contradiction:
ImprovedurabilityVSAvoidinstallation efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

By segmenting the frame into fixed and movable portions with the mounting ear component, the heavy durable frame can be installed more quickly through the sliding mechanism rather than requiring manual positioning of the entire structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting ear component with sliding groove acts as an intermediary mechanism that accelerates the installation process of the heavy frame by providing a guided path, eliminating the need for careful manual positioning

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An optical distribution frame cabinet (200) is provided, including a cabinet (201), where a plurality of optical distribution frames (202) are installed in the cabinet (201). A first end of the optical distribution frame (202) is hinged to the cabinet (201), and a sliding groove (504) is concavely disposed on an end face of a second end of the optical distribution frame (202). A mounting ear component (505) is disposed on an end face of the cabinet (201). The mounting ear component (505) is convexly disposed facing the optical distribution frame (202), and when the mounting ear component (505) is inserted into the sliding groove (504), the mounting ear component (505) slides in a guide direction of the sliding groove (504) until the optical distribution frame (202) is installed into the cabinet (201). According to the optical distribution frame (202), the sliding groove (504) having an inclined surface feature is disposed to cooperate with the mounting ear component (505) of the optical distribution frame cabinet (200), thereby effectively avoiding a phenomenon of local downward inclination in the process of installing the optical distribution frame, and improving efficiency of installing the optical distribution frame.
