Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If data collection and calculation methods are implemented to track quality and defects, then manufacturing precision and quality control are improved, but device complexity and data processing requirements increase
Solution Approach 1:
The patent implements a feedback mechanism by collecting measurement data from the electrode sheet, calculating defect amounts and production amounts, and using this information to adjust and optimize the electrode manufacturing process. The system continuously monitors quality parameters and provides feedback for process improvement, thereby enhancing manufacturing precision through data-driven decision making.
Solution Approach 2:
The patent introduces an intermediary data processing system that acts as a mediator between the physical electrode manufacturing process and the quality control objectives. This intermediary system collects, processes, and analyzes measurement data, transforming raw data into actionable quality metrics without requiring direct modification of the manufacturing equipment itself.
2Loss of information
If comprehensive data collection from electrode sheets is performed, then information about quality and defects is improved, but loss of time for data processing increases
Solution Approach 1:
The patent extracts only the essential and relevant information from the comprehensive measurement data, focusing on key quality parameters and defect characteristics. By selectively extracting critical data points rather than processing all available data, the system maintains high information quality while reducing processing time and computational burden.
Solution Approach 2:
The patent implements partial data processing by focusing on specific critical areas and parameters that have the most significant impact on quality. Rather than analyzing every aspect of the electrode sheet in equal detail, the system applies targeted analysis to high-priority regions and parameters, achieving effective quality control with reduced processing time.
