Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data cables experience asymmetry and degradation in transmission characteristics due to perpendicular forces, which negatively impact signal transmission, especially at high data rates.
Innovation Solution
Incorporating an internal flat element within the data cable that wire pairs lie against, reducing bending and asymmetry, and maintaining symmetry for improved transmission characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If wire pairs are separated spatially using current-carrying wire, then cable structure is simplified, but wire pairs are deformed by perpendicular forces causing asymmetry
Solution Approach 1:
A flat internal element is introduced as an intermediary component between the wire pairs and the external environment. This flat element acts as a mediator that distributes perpendicular forces evenly across the wire pairs, preventing deformation while maintaining the simplified cable structure. The flat internal element transfers and disperses mechanical stress without causing asymmetry in the wire pairs.
Solution Approach 2:
The internal element is designed with a specifically flat local geometry at the region where wire pairs contact it. This localized flat structure provides targeted support exactly where needed - at the wire pair interfaces - while the rest of the cable structure can maintain its overall flexibility and simplicity. The flat region creates a stable, symmetric contact surface that prevents wire pair deformation.
2Ease of operation
If wire pairs are allowed to bend freely, then cable flexibility is improved, but asymmetry in wire pairs degrades transmission at high data rates
Solution Approach 1:
The internal element provides localized flat support only at the wire pair regions, allowing the cable to remain flexible in other areas. The flat contact surfaces are positioned precisely where wire pairs need stabilization, while the cable exterior maintains its flexibility for easy handling and installation. This selective support strategy preserves flexibility without compromising transmission quality.
3Reliability
If internal element adds structural support, then transmission characteristics are improved, but cable complexity and manufacturing difficulty increase
Solution Approach 1:
The internal element is designed as a simple, segmented flat structure that can be easily integrated during cable assembly. Its straightforward geometry allows for simple positioning and attachment to the wire pairs, reducing manufacturing complexity compared to more complex support structures. The segmented or modular nature of the flat element facilitates easier assembly processes.
