Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If comprehensive measurement and inspection data are collected and displayed in the electrode manufacturing process, then quality monitoring and process tracking are improved, but system complexity and data processing requirements increase
Solution Approach 1:
The system segments the electrode manufacturing process into distinct stages (coating, drying, calendering, winding) and displays measurement data for each stage separately in the intermediate roll map. This segmentation allows comprehensive quality monitoring without overwhelming the system, as each segment can be independently monitored and managed.
Solution Approach 2:
The patent introduces an intermediate roll map as a mediator between the manufacturing process and quality analysis. This intermediate representation consolidates measurement data from multiple sources and stages into a unified visual format, reducing the complexity of directly processing and displaying all raw data while maintaining comprehensive quality monitoring capabilities.
2Loss of information
If real-time measurement data is displayed for the entire electrode sheet, then process visibility is improved, but data transmission and processing time increase
Solution Approach 1:
The system extracts and displays only the most critical measurement parameters (thickness, density, coating uniformity) in the intermediate roll map, rather than transmitting and displaying all available data. This selective extraction maintains process visibility while significantly reducing data transmission time and processing requirements.
Solution Approach 2:
The patent implements partial action by displaying representative measurement data at key process stages rather than continuous data from all points. The intermediate roll map shows sufficient detail to maintain process visibility while using only the necessary portion of available data, avoiding the time cost of processing excessive information.
3Manufacturing precision
If detailed coordinate-related measurement data is visualized, then manufacturing precision is improved, but ease of operation decreases due to information overload
Solution Approach 1:
The patent transforms one-dimensional measurement data (thickness, density values along the electrode sheet) into a two-dimensional intermediate roll map visualization. This dimensional transformation allows detailed manufacturing precision data to be displayed in a spatial context that is easier to interpret, showing variations across the electrode surface without overwhelming the operator with numerical data.
Solution Approach 2:
The system uses color coding in the intermediate roll map to represent different measurement parameter ranges (e.g., color gradients indicating thickness variations or density deviations). This visual encoding converts complex numerical data into intuitive color patterns, maintaining manufacturing precision information while dramatically improving ease of operation and rapid interpretation.

AI summary
Example embodiments provide a method of displaying an intermediate roll map. The method includes: transmitting an application programming interface (API) call to a server storing coordinate-related measurement data, in which the coordinate-related measurement data includes measurement data collected based on measurement of an electrode sheet and coordinates related to the measurement data; transmitting the coordinate-related measurement data in response to the API call; and displaying the coordinate-related measurement data.
