Optical Splice Box Cable Tie-Down With Arched Entry Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable securing systems in optical splice boxes face challenges with manual operations becoming increasingly difficult as the number of cables increases, reducing the accessible volume and complicating the securing process.
Innovation Solution
A cable securing system with a base having an axial passage and arches, combined with a lashing support and lashing ring, allows for easy securing of cables by snapping onto the base, using a screw to clamp the cable sheath and aramid strands without external assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual cable securing operations are performed using traditional securing supports, then cable securing can be achieved, but the accessible volume at the bottom of the container reduces and the operation becomes increasingly difficult as the number of cables increases
Solution Approach 1:
The patent moves the cable securing operation from the bottom of the container (2D surface) to the cable entry port area (3D space with vertical dimension). The base is fixed to the cable entry port framed by a tubular base, allowing cables to be secured at the entry point rather than requiring bottom-space manipulation. This dimensional shift eliminates the volume constraint problem.
Solution Approach 2:
The patent introduces a base with arches as an intermediary structure between the container and the cables. The base is fixed to the cable entry port and provides arches that guide and organize cables, making the securing operation easier without consuming bottom volume. This intermediary structure mediates between the cable entry and the securing supports.
2Productivity
If multiple cables are secured manually at the bottom of the container, then all cables can be secured, but the time and complexity of securing operations increases
Solution Approach 1:
The base with arches is pre-fixed to the cable entry port before cable installation. This preliminary arrangement of the securing structure at the entry point allows cables to be organized and secured more efficiently as they are installed, rather than requiring complex bottom-space manipulation for each cable.
Solution Approach 2:
The base with arches serves multiple functions: it provides structural support, organizes multiple cables simultaneously, guides cable positioning, and facilitates securing operations. This multi-functional design improves productivity by handling multiple cables through a single unified structure rather than requiring separate securing mechanisms for each cable.
