Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery manufacturing processes are implemented without comprehensive data tracking systems, then production speed and efficiency are maintained, but traceability and reliability of electrode manufacturing processes deteriorate
Solution Approach 1:
The patent segments the battery manufacturing process into distinct stages (coating process, roll press process, slitting process) with separate coordinate data sets for each stage. Each process generates its own coordinate data that is tracked independently through the electrode's journey, allowing granular traceability without requiring a monolithic complex system.
Solution Approach 2:
The patent uses coordinate data as an intermediary element that bridges different manufacturing processes. The coordinate data set acts as a mediator that connects the coating process, roll press process, and slitting process, enabling traceability through the entire manufacturing chain without direct complex interconnections between all process systems.
2Reliability
If comprehensive coordinate data and inspection data are collected and connected for every electrode, then traceability and quality control are improved, but data management complexity and processing requirements increase
Solution Approach 1:
The patent divides quality control data into process-specific segments: coating inspection data, roll press inspection data, and slitting inspection data. Each data type is collected and managed separately according to its source process, reducing the complexity of managing a unified massive data set while maintaining comprehensive quality control coverage.
Solution Approach 2:
The patent performs preliminary data organization by creating coordinate data sets for each process stage before final integration. Inspection data is pre-associated with its corresponding coordinate data at each process stage, preparing the data structure in advance to simplify subsequent traceability operations and reduce processing complexity.
3Manufacturing precision
If electrode position tracking is implemented across multiple processes, then manufacturing precision and traceability are improved, but system complexity and measurement requirements increase
Solution Approach 1:
The patent implements position tracking by creating separate coordinate data sets for each manufacturing process (coating, roll press, slitting) rather than a single unified tracking system. Each process records electrode coordinates independently, and these segmented coordinate data sets are later integrated to provide comprehensive position tracking across the entire manufacturing chain.
Data Source
AI summary
A battery monitoring system includes at least one memory configured to store a first coordinate-related data set in which coordinate data indicating a position of an electrode moved in each of a plurality of processes is connected with inspection data and/or measurement data of the electrode obtained in the plurality of processes, and an identification data set including an electrode identifier (ID) identifying the electrode. The battery monitoring system further includes at least one processor configured to connect the electrode ID with the coordinate data of the first coordinate-related data set corresponding to the electrode ID, and send monitoring data for the electrode, based on data about the connection of the electrode ID with the coordinate data.
