Solution Overview

Problem

Existing optical fiber distribution devices are not flexible enough and have complex connecting mechanisms, making them difficult to use in various situations and complicating their application.

Innovation Solution

An optical fiber distribution device with an inner frame that can rotate in two directions and linearly slide out of an outer box, featuring mechanical connecting means that allow for three types of movement (rotation, translation, and locking) without requiring specialized tools, and includes elastically deformable side wings for easy sliding and standard shafts for rotation, enabling adaptable configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the inner frame is made movable inside the outer box with multiple movement options, then the adaptability and flexibility of the device is improved, but the device complexity increases

Engineering Contradiction:
ImproveflexibilityVSAvoidcomplexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The inner frame is designed to be dynamically movable within the outer box, capable of rotating in two opposite directions and sliding linearly. This dynamic configuration allows the device to adapt to various cable management situations while maintaining a relatively simple overall structure through well-defined movement constraints.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the inner frame can be easily removed and repositioned, then the ease of operation is improved, but the reliability of the connection between frame and box deteriorates

Engineering Contradiction:
Improveease of applicationVSAvoidconnection stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The connecting means are segmented into discrete, easily removable components that allow the inner frame to be detached and repositioned without tools. This segmentation maintains simple operation while ensuring reliable connection when assembled, as each segment can be securely engaged.

Inventive Principle:
Principle #1Segmentation

3Volume of moving object

If the device is designed to be compact for transportation, then the volume is reduced, but the ease of operation for cable connections deteriorates

Engineering Contradiction:
Improvedevice volumeVSAvoidease of use
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The inner frame is nested within the outer box in a compact configuration for transportation and storage. When cable connections are needed, the inner frame can be extracted and repositioned, providing ease of operation. This nesting arrangement minimizes volume during transport while maintaining full functionality during use.

Inventive Principle:
Principle #7Nested doll (Nesting)
