Twisted Pair Cables With Dielectric Separators For Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional twisted pair communication cables rely on colorants for identification, which increase costs and environmental impact, prompting the need for cables with reduced or minimal colorant usage while maintaining proper identification of pairs and conductors.
Innovation Solution
The development of twisted pair communication cables that utilize polymeric materials without colorants and incorporate physical indicia, such as surface variations or limited colorant markings, to facilitate identification without the need for colored insulation, allowing for reduced or zero colorant usage while ensuring proper installation and identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If colorants are used in cable insulation to identify twisted pairs and conductors, then identification capability is improved, but environmental impact and cost increase
Solution Approach 1:
The patent applies color changes by using color-coded identifiers on the cable jacket and/or separator instead of coloring the entire insulation. The insulation itself remains substantially free of colorant, while strategic use of color on external components provides the necessary identification information for twisted pairs and conductors, thereby reducing environmental impact while maintaining identification capability.
2Loss of information
If colorants are used in cable insulation to identify twisted pairs and conductors, then identification capability is improved, but cable cost increases
Solution Approach 1:
The patent reduces cable cost by limiting colorant application to specific identification zones on the cable jacket and separator rather than incorporating colorants throughout the insulation material. This selective coloring approach maintains full identification capability for installation purposes while significantly reducing material costs and manufacturing complexity associated with color-coded insulation.
3Object-affected harmful factors
If colorants are eliminated from cable insulation, then environmental sustainability is improved, but identification capability may be compromised
Solution Approach 1:
The patent applies segmentation by dividing the identification function between multiple cable components: the cable jacket receives color-coded identifiers for twisted pair identification, the separator may include color or physical indicia for additional pair differentiation, and the insulation remains substantially free of colorant. This segmented approach distributes the identification information across components, maintaining full identification capability while eliminating harmful colorants from the insulation material.
Solution Approach 2:
The patent uses the cable jacket and separator as intermediary elements that carry identification information. Instead of relying on colored insulation, these external components serve as mediators that provide the necessary visual cues for identifying twisted pairs and conductors, allowing the insulation to remain environmentally friendly while identification needs are met through these intermediary structures.
