Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The relative movement between a passing roller and the pole piece during transmission leads to deviations in the labeling position, causing abnormal labeling in the pole piece detection process.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pre-measured distance is used for labeling based on fixed transmission parameters, then the labeling process is simple and fast, but the labeling position deviates due to relative movement between passing roller and pole piece
Solution Approach 1:
The patent dynamically adjusts the labeling delay parameter based on the actual position of the pole piece detected by the visual detection system. Instead of using a fixed pre-measured distance, the system calculates the real-time distance between the mark hole and labeling position, and adjusts the labeling delay accordingly. This parameter change approach resolves the contradiction by maintaining fast automated labeling while eliminating position deviations caused by relative movement.
Solution Approach 2:
The patent implements a feedback mechanism where the visual detection system continuously monitors the position of the pole piece and mark hole, and this information is fed back to adjust the labeling delay in real-time. The system measures the actual distance from the mark hole to the labeling position and uses this feedback to correct the labeling timing, ensuring accurate labeling position while maintaining high productivity through automated real-time adjustment.
2Manufacturing precision
If real-time visual detection and dynamic adjustment are implemented to eliminate labeling position deviation, then the labeling position accuracy is improved, but the system complexity increases
Solution Approach 1:
The patent uses the existing visual detection system, originally designed for defect detection, to also perform position measurement for labeling control. The same camera and image processing algorithms are utilized for both detecting pole piece defects and measuring the position of mark holes. This multi-functionality approach reduces system complexity by avoiding duplicate equipment while achieving accurate labeling position control.
Solution Approach 2:
The patent introduces a control system that acts as an intermediary between the visual detection system and the labeling device. This intermediary processes the image data, calculates the required labeling delay, and sends control signals to the labeling device. By using this intermediary layer, the system achieves precise labeling control through a modular architecture that manages complexity effectively while maintaining high positioning accuracy.
