Solution Overview
Problem
Existing communication cables face challenges with noise, interference, and crosstalk, particularly with continuous shielding methods that can create electrical paths and interfere with signals, pose shock hazards, and radiate electromagnetic energy.
Innovation Solution
A communication cable with a segmented shield comprising electrically isolated conductive patches attached to a dielectric substrate, which prevents continuous electrical paths and effectively blocks electromagnetic interference while maintaining signal integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a continuous shield is used to shield the cable, then electromagnetic interference is blocked, but standing waves and electromagnetic radiation are created
Solution Approach 1:
By segmenting the continuous shield into discrete patches separated by dielectric material, the structure prevents the formation of continuous conductive paths that support standing waves. The gaps disrupt electromagnetic resonance while each individual patch continues to provide local EMI shielding.
2Object-affected harmful factors
If a continuous shield is used to shield the cable, then electromagnetic interference is blocked, but installation complexity and grounding requirements increase
Solution Approach 1:
The segmented shield design with discrete conductive patches on dielectric substrate eliminates the need for continuous grounding along the cable length. Each patch is electrically isolated, simplifying installation by removing complex grounding requirements while maintaining effective EMI shielding.

AI summary
A cable shield tape can comprise patches of electrically conductive material disposed adjacent a strip of dielectric material, with the patches electrically isolated from one another. An attachment system can mechanically attach the patches to the dielectric material, for example to avoid flammable adhesives. The attachment system can comprise one or more mechanical fasteners, rivets, staples, clips, clamps, metallic members, nonorganic materials, nonflammable materials, holes, holes with flared or mushroomed rims, protrusions, etc. The attachment system can also or alternatively comprise technology for knolling, punching, seating, surface patterning, peening, embossing, etc. The tape can be wrapped around one or more cable conductors, such as wires that transmit data, to provide electrical or electromagnetic shielding. The resulting cable can have a shield that is electrically discontinuous between opposite ends of the cable.
