Solution Overview
Problem
Existing electrical lines in vehicles, particularly those used in hybrid and electric motor vehicles, lack a reliable method to continuously monitor their functional integrity, especially when exposed to high electrical voltages, which can pose safety risks if damaged.
Innovation Solution
Incorporating a light guide integrated within the shield of the electrical line, allowing for constant monitoring of the line's integrity through deformation or damage detection using light pulses, and triggering an immediate disconnection from the voltage source via an evaluation unit and switching element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical lines are used in high-voltage vehicle systems without continuous monitoring, then device complexity is reduced, but functional reliability deteriorates due to undetected damage
Solution Approach 1:
The light guide is integrated directly into the shield structure of the electrical line, merging the monitoring function with the existing protective shielding. This combination allows continuous reliability monitoring without adding separate external monitoring components, thus improving reliability while minimizing the increase in device complexity.
Solution Approach 2:
The patent replaces potential mechanical damage detection methods with an optical monitoring system. The light guide uses optical principles to detect shield deformations or breaches, substituting mechanical sensing approaches with a more sensitive optical field-based detection method that can continuously monitor integrity without physical contact.

If a light guide is integrated into the shield for continuous monitoring, then functional reliability is improved, but device complexity increases
Solution Approach 1:
The light guide is integrated directly into the shield structure of the electrical line, merging the monitoring function with the existing protective shielding. This combination allows continuous reliability monitoring without adding separate external monitoring components, thus improving reliability while minimizing the increase in device complexity.
3Measurement precision
If the light guide is positioned far outside in the cable structure, then damage detection precision is improved, but the cable structure becomes more complex
Solution Approach 1:
The light guide is integrated directly into the shield structure of the electrical line, merging the monitoring function with the existing protective shielding.

AI summary
The line (5) has a set of insulated electrical conductors (6-8) surrounded by a common electrically effective screen (9). A light conductor (10) is presented in construction of the line over entire length of the line. The light conductor is connected to an evaluating unit that is connected to a switching element in an operating position and integrated in the screen or directly underneath the screen while contacting the screen such that damage to the line produces with certainty of deformation of the light conductor that results in a signal to be recognized by the evaluating unit.
