Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual inspection data verification is used in the electrode process, then inspector flexibility is maintained, but traceability and reliability are insufficient
Solution Approach 1:
The system performs preliminary actions by automatically collecting, storing, and verifying inspection data before final quality decisions are made. Coordinates, inspector IDs, and defect information are pre-processed and matched against raw inspection data, ensuring traceability is established in advance rather than retroactively.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring the matching between coordinate-related inspection data and raw inspection data. When mismatches are detected beyond allowable errors, the system generates alerts and prevents progression, creating a closed-loop verification system that continuously improves reliability.
2Reliability
If comprehensive inspection data verification is implemented, then manufacturing reliability improves, but processing time increases
Solution Approach 1:
The patent replaces manual mechanical verification processes with automated computer-based systems. The server automatically compares coordinates, inspector IDs, and defect sequence numbers between different data sources, eliminating time-consuming manual verification while maintaining comprehensive checking of all inspection parameters.
Solution Approach 2:
The system creates and verifies multiple copies of inspection data from different sources (coordinate-related inspection data and raw inspection data). By automatically comparing these data copies against each other and against allowable error margins, the system ensures comprehensive verification without requiring sequential manual review of each data set.
3Productivity
If automated data monitoring is implemented, then productivity increases, but system complexity increases
Solution Approach 1:
The monitoring system is designed with multi-functionality to justify its complexity. It simultaneously performs multiple tasks: collecting coordinates, storing inspector IDs, tracking defect sequence numbers, verifying data matching, generating alerts, and preventing defective product progression. This universal system replaces multiple separate manual processes, netting a productivity gain despite the initial complexity investment.
Solution Approach 2:
The server acts as an intermediary between various inspection devices and the quality control system. It centralizes data collection, storage, and verification functions, mediating between raw inspection data and coordinate-related inspection data. This intermediary approach consolidates complexity into a single manageable component while enabling automated high-speed verification that improves overall productivity.

AI summary
Example embodiments provide a secondary battery manufacturing method. The secondary battery manufacturing method includes: loading coordinate-related inspection data and coordinate-related raw inspection data of an electrode sheet, in which the coordinate-related inspection data includes an image and a coordinate of a part of the electrode sheet, and the coordinate-related raw inspection data includes a judgment on whether the part of the electrode sheet includes a surface defect and the coordinate of the part of the electrode sheet; and monitoring matching between the coordinate-related inspection data and the coordinate-related raw inspection data.
