Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the incision depth is increased to ensure complete severing of the insulating sheath, then the insulating sheath is completely cut, but the conductor is damaged
Solution Approach 1:
The patent employs a capacitive sensor that continuously monitors the distance between the stripping blade and the conductor during the stripping process. When the insulating sheath is completely severed and the blade approaches the conductor, the sensor detects the change in capacitance and sends a signal to automatically retract the blade, preventing conductor damage while ensuring complete sheath severing
Solution Approach 2:
The system performs a preliminary detection phase before the actual stripping operation. The capacitive sensor scans the cable to identify the precise location and depth of the insulating sheath, allowing the control system to pre-calculate the optimal blade trajectory and incision depth to achieve complete severing without contacting the conductor
2Object-affected harmful factors
If the incision depth is decreased to avoid conductor damage, then the conductor is protected, but the insulating sheath is not completely severed
Solution Approach 1:
The stripping blade's incision depth and trajectory are dynamically adjusted during the stripping process based on real-time feedback from the capacitive sensor. The control system continuously modifies the blade's movement parameters to maintain optimal cutting depth, ensuring complete sheath severing while preventing conductor contact
Solution Approach 2:
The system changes the operational parameters of the stripping blade, including incision depth, blade speed, and retraction timing, based on real-time sensor data. These parameter adjustments allow the system to adapt to variations in cable geometry and ensure complete sheath severing without damaging the conductor
3Reliability
If multiple incisions are made to statistically evaluate and optimize stripping parameters, then the stripping parameters can be optimized, but the process becomes time-consuming and material is rejected
Solution Approach 1:
The system performs self-optimization by using the capacitive sensor to automatically detect and learn the optimal stripping parameters during normal operation. The control system analyzes sensor data in real-time and automatically adjusts parameters without requiring external intervention or multiple test incisions, eliminating time loss and material rejection
Solution Approach 2:
The patent replaces manual trial-and-error optimization and visual inspection with an automated electronic sensor-based system. The capacitive sensor provides precise, real-time measurement of the stripping process, allowing the control system to automatically optimize parameters without time-consuming manual evaluation and material rejection
4Measurement precision
If visual inspection is performed to check stripping quality, then the quality can be verified, but the process requires considerable outlay and time
Solution Approach 1:
The patent replaces manual visual inspection with an automated capacitive sensor system that continuously monitors the stripping process in real-time. The sensor detects the precise moment when the insulating sheath is completely severed and when the conductor is approached, providing objective, precise quality verification without requiring time-consuming manual inspection
Solution Approach 2:
The capacitive sensor provides continuous feedback during the stripping process, allowing the control system to verify quality in real-time and make immediate adjustments if needed. This eliminates the need for post-process visual inspection, saving time and reducing costs while maintaining high measurement precision

AI summary
A method for stripping and testing of a cable having at least one conductor enclosed in an insulating sheath uses a stripping device with at least one stripping blade. The method steps include: extending the stripping blade in a transverse direction to sever the insulating sheath; displacing the stripping blade in a longitudinal direction to pull off the severed insulating sheath; detecting a contacting of the conductor; retracting of the stripping blade in the transverse direction when the contacting is detected; recording the movement data of the stripping blade at the time of contacting; determining a further movement course of the stripping blade from the movement data and forming a corresponding local quality value is formed; and comparing the local quality value with a quality specification to establish whether a quality of the conductor meets requirements.
