Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual observation is used for detecting internal defects in batteries, then the detection method is simple and easy to implement, but the detection accuracy is low
Solution Approach 1:
The patent replaces manual observation with an automated optical detection system comprising a camera, light source, and control unit. The system captures images of battery electrodes and automatically analyzes defects such as wrinkles, folding, and misalignment, eliminating the need for manual inspection while significantly improving detection accuracy and consistency.
Solution Approach 2:
The patent creates visual copies (images) of the battery electrode surfaces using a camera system. These images are then processed and analyzed to detect internal defects. The copying process allows for detailed examination of electrode conditions without physically touching or disturbing the battery components.
2Productivity
If traditional detection methods are used, then the equipment is simple, but the detection efficiency and compatibility with production takt are low
Solution Approach 1:
The patent implements a continuous detection system where the camera continuously captures images of battery electrodes as they move through the production line. The control unit continuously processes these images to detect defects, ensuring uninterrupted monitoring that matches the production takt and maintains constant quality control without stopping the production flow.
Solution Approach 2:
The detection system is designed to automatically capture, process, and analyze images without requiring external intervention. The control unit autonomously evaluates the captured images, identifies defects based on predetermined criteria, and generates detection results, making the system self-sufficient and highly efficient in keeping pace with production requirements.
3Measurement precision
If single-angle detection is used, then the detection process is fast, but there are detection blind spots and accuracy is limited
Solution Approach 1:
The patent transitions from single-angle detection to multi-angle detection by positioning light sources and cameras at multiple angles around the battery electrode. This multi-dimensional approach allows the system to capture images from different perspectives, eliminating blind spots and providing comprehensive coverage of the electrode surface, including areas that would be invisible from a single viewpoint.
Solution Approach 2:
The detection process is segmented into multiple angular views, with each camera and light source combination capturing a specific portion or angle of the electrode. By dividing the detection task into multiple angular segments and combining the results, the system achieves complete coverage and high accuracy without requiring excessively long detection times.
