Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cables lack effective and practical means to detect internal damage, as conventional methods require additional sensors that are not feasible due to space constraints and increased costs, posing safety and maintenance challenges.
Innovation Solution
A cable design incorporating a signal detection layer made of synthetic graphene, which is electrically coupled to the conductor assembly when the first insulating layer is damaged, allowing for timely detection of abnormalities without additional sensors, and a leakage detection circuit breaker system to disconnect power in case of leakage current.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sensor or inductive transmission device is installed in the cable to detect internal damage, then the cable can detect abnormalities, but the interior space is consumed and the cost increases
Solution Approach 1:
The patent combines the detection function with the existing insulating layer by making the insulating layer itself conductive when damaged. Instead of adding a separate sensor, the insulating layer's electrical properties are used to detect damage, merging the structural and detection functions into one component.
Solution Approach 2:
The cable structure uses its own insulating layer to perform the detection function. When the insulating layer is damaged, it automatically changes electrical properties that can be detected, allowing the system to self-diagnose without external sensors.
2Reliability
If a sensor or inductive transmission device is installed in the cable to detect internal damage, then the cable can detect abnormalities, but the installation cost increases
Solution Approach 1:
The detection function is merged into the insulating layer itself, eliminating the need for separate expensive sensors and inductive transmission devices. This reduces material costs and simplifies the manufacturing process.
Solution Approach 2:
The insulating layer serves dual purposes: electrical insulation and damage detection. This eliminates the need for additional detection components, reducing overall cable manufacturing costs while maintaining detection capability.
3Reliability
If multiple devices are installed in the cable for detection purposes, then the detection function is enhanced, but the cable design becomes more difficult
Solution Approach 1:
The patent merges the detection function into the existing insulating layer structure, avoiding the need for multiple separate devices. This maintains detection accuracy while simplifying the overall cable design and reducing the number of components that need to be integrated.

AI summary
A cable with a signal detection function includes an core, a second insulating layer, and a signal detection layer. The signal detection layer is for transmitting signal data. The cable further includes a second insulating layer, and plural signal detection layers provided for transmitting signal data. The signal detection layer and the cores are disposed inside the second insulating layer, and the signal detection layer is cladded with plural cores. If the first insulating layer in the signal detection layer is damaged, the signal detection layer will be electrically connected to the conductor assembly. The cable with the signal detection function can detect the abnormality of the core through the signal detection layer to facilitate maintaining and repair the cable.
