Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable stripping methods often damage conductor ends due to contact with stripping tools, and the quality of stripping is difficult to determine efficiently, leading to rejected cables and inefficient process adjustments.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If optical inspection with microscope is used to determine conductor quality, then conductor quality can be determined, but the process becomes complex and time-consuming
Solution Approach 1:
The patent replaces the mechanical/optical inspection system (microscope) with an electrical sensing system. Sensors detect conductor quality through electrical properties during the stripping process, eliminating the need for complex optical microscopy while maintaining measurement precision.
Solution Approach 2:
The stripping device performs self-inspection by using sensors integrated into the stripping mechanism itself. The sensors detect conductor contact and quality parameters during the normal stripping operation, so the same device that strips the cable also inspects it, eliminating separate inspection equipment.
2Measurement precision
If optical inspection is performed after stripping completion, then conductor quality can be assessed, but the stripping process cannot be efficiently adjusted
Solution Approach 1:
The patent implements preliminary quality detection during the stripping process itself. Sensors monitor conductor contact and quality parameters in real-time before the stripping is complete, allowing immediate detection of potential quality issues and enabling proactive adjustments rather than reactive corrections after the fact.
Solution Approach 2:
The system incorporates real-time feedback through sensors that continuously monitor conductor quality during stripping. This feedback is immediately available to control systems, enabling dynamic adjustment of stripping parameters to maintain optimal quality without waiting for post-process inspection results.
3Reliability
If multiple rejected cables result from inefficient quality determination, then conductor quality can be ensured, but productivity decreases
Solution Approach 1:
By detecting conductor quality issues during the stripping process rather than after completion, the system prevents defective cables from being produced in the first place. This preliminary detection and immediate correction capability eliminates rework and rejection cycles, maintaining high productivity while ensuring quality.
Solution Approach 2:
Replacing complex optical inspection with simpler electrical sensing reduces measurement time and enables real-time quality control. This substitution allows for faster detection and adjustment, preventing cable rejections and maintaining higher throughput while ensuring quality standards are met.

AI summary
A method for stripping a cable, the cable having a conductor encompassed by an insulation and extending in a longitudinal direction, includes cutting into the insulation with stripping blades, after which the insulation is removed by sliding the stripping blades in the longitudinal direction. During the removal procedure, the longitudinal position of the stripping blades is detected if it has been determined by a detection device that at least one of the stripping blades has come in contact with the conductor. Based on the longitudinal position of one or more contacts with the conductor, a classification of the cable as adequately or poorly stripped is carried out.
