Low-Density Cylindrical Enclosure for Optical Waveguide Cable
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional optical waveguide cables lack a lightweight yet durable cylindrical enclosure that provides adequate protection and flexibility for outdoor and underground applications, while also minimizing water ingress and facilitating easy splicing without the need for cleaning agents.
Innovation Solution
The optical waveguide cable features one or more optical waveguide bands edge-bonded with light transmission elements, encapsulated within a cylindrical enclosure made of a material with a density of at most 0.935 g/cm³, offering environmental stress cracking resistance, tensile strength, and flexibility, along with a water-blocking system to prevent moisture ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a traditional cylindrical enclosure is used for optical waveguide cable, then protection and durability are provided, but the cable becomes heavy and less flexible
Solution Approach 1:
The patent applies parameter changes by specifying a density parameter for the cylindrical enclosure material (at most 0.935 g/cm³). This density constraint enables the selection of lightweight materials that maintain protective functions while reducing overall cable weight and improving flexibility for outdoor and underground installations.
2Loss of time
If gel is present inside the core of optical fiber ribbon cable, then water blocking is provided, but preparation time and installation complexity increase
Solution Approach 1:
The patent extracts the gel substance from the core of the optical fiber ribbon cable, eliminating the need for gel-based water blocking. Instead, the water-blocking function is achieved through the structural design of the cylindrical enclosure and layer configuration, thereby reducing preparation time and simplifying installation procedures while maintaining protection against water ingress.
3Reliability
If optical fiber ribbons are individually protected with additional layers, then reliability is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent merges multiple protective layers and structural elements into a unified cylindrical enclosure structure. The optical fiber ribbons are bundled and collectively protected within a single cylindrical enclosure with integrated water-blocking and mechanical protection features, reducing manufacturing complexity while maintaining comprehensive protection for all ribbons.
