Shielded Cable Integrating Embedded Electrical Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shielded electrical cables for data transmission in motor vehicles do not effectively integrate electrical devices within the cable structure, often relying on external connections or connectors, which limits their functionality and integration.
Innovation Solution
The integration of an electrical device, such as an RFID element or integrated circuit, between the conductors and the cable shield, where it is in direct electrical contact with the conductors, allowing for secure and fixed attachment via material-to-material bonds or connecting elements, and optionally surrounded by a protective layer, enabling the device to be securely embedded within the cable without external connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electrical devices are integrated between the conductors and cable shield, then functionality and data transmission capabilities are enhanced, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent merges the electrical device with the cable structure by positioning it between the conductors and cable shield, creating an integrated assembly where the cable itself serves as the mounting structure, eliminating the need for separate external connectors or mounting hardware
Solution Approach 2:
The cable structure is designed to serve multiple functions: it provides electrical connection through conductors, shielding through the cable shield, and device mounting through the integrated space between conductors and shield, making the cable a multi-functional component rather than just a connection element
2Reliability
If electrical devices are securely embedded within the cable structure, then reliability of electrical contact is improved, but manufacturing precision requirements increase
Solution Approach 1:
The cable is designed with pre-defined spaces and structures between the conductors and cable shield that are prepared in advance to receive and accommodate electrical devices, ensuring proper positioning and contact without requiring complex post-assembly adjustments
Solution Approach 2:
The electrical device is nested within the cable structure, specifically positioned in the space between the conductors and cable shield, creating a compact integrated assembly where each component fits within the overall cable architecture
3Object-affected harmful factors
If electrical devices are surrounded by cable shield and embedded in conductors, then protection and electrical contact are improved, but ease of manufacture decreases
Solution Approach 1:
The patent combines the shielding function and device protection into a single integrated structure where the cable shield serves both as electromagnetic shielding and as the outer protective layer for the embedded electrical device, eliminating the need for separate protective housings

AI summary
A shielded electrical cable includes at least two spaced-apart conductors extending side-by-side along a longitudinal cable direction. An insulation electrically insulates the conductors from each other. A cable shield, together with the conductors, extends along the longitudinal cable direction and annularly surrounds the conductors, as seen in cross section. An electrical device is disposed between the conductors and the cable shield. The electrical device is surrounded by the cable shield and disposed on the conductors such that the electrical device is in electrical contact with each of the conductors.
