Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complete cable shielding is provided using conductive tape wrapped around the entire cable core, then signal transmission performance is improved by reducing crosstalk, but manufacturing cost increases and grounding requirements are introduced
Solution Approach 1:
The continuous conductive tape shield is segmented into discrete shielding components positioned at specific locations around the cable core. Each shielding component is wrapped around individual twisted conductor pairs or groups of pairs at specific circumferential positions, eliminating the need for complete 360-degree coverage. This segmentation reduces material usage and manufacturing complexity while maintaining effective shielding where most needed.
Solution Approach 2:
Instead of providing uniform shielding around the entire cable circumference, the invention applies shielding locally at specific positions where crosstalk protection is most critical. The shielding components are strategically positioned to protect vulnerable conductor pairs without requiring complete circumferential coverage, optimizing the balance between performance and cost.
2Object-affected harmful factors
If conductive tape is wrapped around the entire cable core in an overlapping manner to provide complete shielding, then crosstalk reduction is achieved, but material cost and manufacturing complexity increase
Solution Approach 1:
The invention applies partial shielding action by positioning discrete shielding components at specific locations rather than providing complete circumferential coverage. This partial action is sufficient to reduce crosstalk effectively while using significantly less conductive tape material compared to complete wrapping.
Solution Approach 2:
The continuous tape is divided into discrete shielding components that are positioned independently at optimal locations. This segmentation allows precise placement of shielding only where needed, eliminating material waste from overlapping wraps and unnecessary coverage areas.
3Reliability
If complete cable shielding is implemented, then signal transmission performance improves, but grounding requirements and connector complexity increase
Solution Approach 1:
The invention extracts the grounding requirement from the shielding system by using dielectric material instead of conductive tape. The dielectric shielding components provide electromagnetic shielding through their physical structure and positioning without requiring electrical grounding, thereby eliminating the complexity associated with grounding connections and specialized connectors.
Solution Approach 2:
The dielectric shielding components are simpler, less expensive alternatives to traditional conductive shields. They eliminate the need for expensive grounding infrastructure and specialized connectors, making the overall system more cost-effective and easier to install and maintain.
