Power Cable Radiation Marking for Precise Defect Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During power cable manufacturing, identifying and locating acceptable defects, deviations, or factory joints with high accuracy is challenging, as these regions typically have lower mechanical strength and can be difficult to pinpoint during production and installation.
Innovation Solution
A method of marking locations of interest on a power cable using a marker that can transmit radiation, such as a radioisotope or a communications device, allowing for accurate localization using radiation detection during manufacturing and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional marking methods are used during power cable manufacturing, then the manufacturing process is simple, but the location of interest cannot be localized with high accuracy
Solution Approach 1:
The patent applies a radioactive marker that emits detectable radiation (analogous to color change) at the location of interest on the power cable. This allows the detector to identify and localize the marked position with high precision by detecting the radiation signal, resolving the contradiction between measurement precision and device complexity.
2Loss of time
If no marker is provided at the location of interest, then the cable structure remains simple, but time is lost during localization during production and installation
Solution Approach 1:
The radioactive marker is applied during the manufacturing process at the location of interest before the cable is installed. This preliminary action ensures that when the cable is later handled or installed, the location can be quickly localized using a detector without time loss, thus resolving the contradiction between time loss and device complexity.
3Measurement precision
If excessive cable length is used to account for localization uncertainty, then localization accuracy is effectively improved, but material waste increases
Solution Approach 1:
The patent replaces the mechanical approach of adding excessive cable length to account for localization uncertainty with a radiation detection system. The radioactive marker and detector provide precise electronic localization, eliminating the need for material buffer and resolving the contradiction between measurement precision and substance loss.
