Cable Detection Line Layout for Stepwise Wire Breakage Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire breakage detection systems are not capable of accurately predicting wire breakage through stepwise detection, as they rely on detection lines with elemental wires of varying flex lives, which can lead to incomplete or inaccurate detection of wire damage.
Innovation Solution
A cable with an abnormality sign detection function that incorporates a detection line with long-life and short-life elemental wires, where the short-life wires are arranged around a bundle of long-life wires, allowing for stepwise detection of wire breakage by measuring changes in characteristic impedance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a detection line with elemental wires of varying flex lives is used, then wire breakage detection capability is improved, but detection accuracy deteriorates due to incomplete or inaccurate detection
Solution Approach 1:
The detection line is segmented into multiple elemental wires with different flex lives (short-life, medium-life, long-life wires). Each segment breaks at different stages of cable fatigue, enabling stepwise detection of wire breakage progression. This segmentation allows the system to detect different stages of cable degradation separately, improving overall detection accuracy while maintaining reliable breakage detection capability.
2Loss of time
If the flex life of detection line is made shorter than target wire, then early detection of wire damage is improved, but detection sensitivity to specific damage stages deteriorates
Solution Approach 1:
Different elemental wires within the detection line are assigned different local qualities in terms of flex life. Short-life wires are designed to break early, medium-life wires break at intermediate stages, and long-life wires break later. This local quality differentiation allows the system to maintain early detection capability while simultaneously providing sensitive detection of specific damage stages through the characteristic breakage patterns of different wire types.

AI summary
A cable with an abnormality sign detection function and a wire abnormality sign detection system that can perform stepwise detection of signs leading to breakage in a wire accurately.
