Configurable Signal Cable with Removable EMF Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional signal transmission cables lack the ability to vary electromagnetic field (EMF) emissions along their length, limiting the options for perimeter responses by robotic mechanisms, and do not allow for removable EMF shielding, which restricts the flexibility in signal transmission.
Innovation Solution
A signal transmission cable with a configuration that includes an inner signal wire, a shielding layer, and an outer protective layer, where portions of the outer protective layer and shielding layer can be selectively removed to vary EMF emissions, allowing for variable EMF transmission and multiple signal wires, and is designed to be used in both aboveground and underground applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a shielding layer is used to prevent electromagnetic field escape, then electromagnetic field emission is controlled, but the ability to vary EMF emissions along the cable length is lost
Solution Approach 1:
The shielding layer is divided into multiple discrete sections along the cable length, with each section independently removable or reconfigurable. This segmentation allows specific portions of the cable to emit EMF while other portions remain shielded, enabling variable EMF emission patterns along the cable length while maintaining overall emission control through the remaining shielded sections.
Solution Approach 2:
The shielding layer is designed with dynamic reconfigurability, allowing users to add, remove, or reposition shielding sections based on operational requirements. This dynamic characteristic enables the cable to adapt its EMF emission profile along its length while maintaining the ability to control overall electromagnetic field emission when needed.
2Object-affected harmful factors
If a continuous shielding layer is used, then electromagnetic field emission is prevented, but signal transmission flexibility is restricted
Solution Approach 1:
The continuous shielding layer is segmented into discrete, independently removable sections. This allows users to flexibly configure which sections emit signals and which remain shielded, providing operational flexibility in signal transmission while maintaining electromagnetic field prevention capabilities in the shielded sections.
Solution Approach 2:
Different sections of the cable are assigned different shielding characteristics - some sections have full shielding for electromagnetic field prevention, while other sections have reduced or no shielding for flexible signal transmission. This local differentiation allows the cable to simultaneously provide both functions along its length.
3Adaptability or versatility
If EMF shielding is made removable, then EMF emission variability is enabled, but cable structural integrity is compromised
Solution Approach 1:
The cable is constructed with modular shielding sections that can be independently removed or reconfigured without compromising the overall cable structure. Each segment is designed to be detachable while maintaining connections to adjacent segments, allowing EMF emission variability through reconfiguration while preserving cable structural integrity through proper modular design.
Solution Approach 2:
The cable is pre-configured with attachment mechanisms and connection points that facilitate easy removal and reconfiguration of shielding sections. These preliminary structural preparations enable EMF emission variability through simple user actions while ensuring that the cable maintains its structural integrity through robust pre-engineered connection systems.

AI summary
A signal transmission cable configurable to allow variable electromagnetic field transmission along a length thereof is disclosed herein. The signal transmission cable includes at least one inner signal wire, the at least one inner signal wire configured to convey a signal originating from a signal transmitter; a shielding layer circumscribing the at least one inner signal wire, the shielding layer configured to prevent an electromagnetic field from escaping exteriorly from the signal transmission cable; and an outer protective layer circumscribing the shielding layer, the outer protective layer configured to prevent damage to the shielding layer and the at least one inner signal wire. One or more portions of the outer protective layer and the shielding layer are configured to be selectively removed by a user so as to enable the electromagnetic field emanating from the signal transmission cable to be varied.
