Multi-Directional Optical Termination Unit for Straight Cable Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical termination units restrict the direction of optical cable insertion, necessitating bending and limiting compactness, which hampers efficiency in cable laying and servicing operations, and are not adaptable to varying cable orientations common in building construction.
Innovation Solution
A compact optical termination unit with a connection panel that allows optical cable insertion from multiple directions (upward, downward, leftward, rightward, and rearward) through a rectangular solid-shaped enclosure with adjustable inlet orientations, eliminating the need for bending and maintaining compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connection unit is secured to the second surface slanting upward, then the optical cable can be secured with fixtures, but the extending direction of the optical cable is necessarily limited to the second surface or its close vicinity, requiring bending when introduced from other directions
Solution Approach 1:
The optical termination unit is divided into a front panel section (with connection units) and a rear section (with cable access openings), allowing independent optimization of each section. The front panel maintains its slanted surface for reliable cable securing, while the rear section provides multiple directional access points.
Solution Approach 2:
The patent introduces cable access openings at multiple spatial locations (front, rear, left, right sides) of the enclosure, transforming the single-direction cable access into multi-directional access. This allows cables to be introduced from various directions without bending while maintaining the original slanted surface configuration.
2Ease of operation
If the optical cable is introduced vertically or horizontally from behind, then cable access is achieved, but larger lower limits of curvature radius are required, increasing the size of the optical termination unit and diminishing compactness
Solution Approach 1:
The patent pre-configures multiple cable access openings at optimal locations on the enclosure before cable installation. This allows cables to be directly routed into the unit from various directions without requiring large bending radii, maintaining compact dimensions while facilitating easy cable installation.
3Reliability
If the second surface is inclined at approximately half of a right angle, then cable securing is improved, but the structure is not adaptable to varying cable orientations common in building construction
Solution Approach 1:
The patent makes the optical termination unit universally adaptable to different cable orientations by providing multiple cable access openings at various locations (front, rear, left, right sides). The slanted second surface maintains its cable securing function, while the multiple openings accommodate cables from different directions, making the unit versatile for various building construction scenarios.

AI summary
An optical termination unit is provided for allowing an optical cable to be easily projected straight in any of five directions, including upward, downward, rightward, leftward, and rearward directions, thereby enhancing the efficiency of cable laying or the like. An end securing box 150 of the optical termination unit 100 includes a two-stage multi-tiered box structure separable to two bodies, the first stage including a clamp tray 120 and the second stage including a fusion tray 130 which is provided with a lid (lid 140) thereupon. An inlet Im (m=1, 2, 3, 4, 5) for introducing the end of a second optical cable to be embedded in a wall or a pillar is provided at each face of the enclosure. Holes H1 and H2 formed on the rear face 115 are provided for securing the end securing box 150 with a nylatch n. The end securing box 150 having a rectangular solid shape has multiple holes formed therein. This allows the end securing box 150 to be secured to a rear face 115 so as to be arbitrarily oriented on a right angle basis.
