Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional cutting methods are used without offset compensation, then the cutting process is simple and fast, but the cutting accuracy deteriorates due to manufacturing and installation errors
Solution Approach 1:
The patent applies preliminary action by pre-calculating and compensating for offset distances between the detection reference and cutting position before the actual cutting operation. The system obtains offset distance information in advance, uses it to calculate corrected cutting parameters, and then performs the cutting operation with improved accuracy. This resolves the contradiction by adding a preliminary compensation step that improves cutting accuracy without significantly increasing overall process complexity.
Solution Approach 2:
The patent implements feedback by using detection reference points to measure actual positions, calculating offset distances from these measurements, and using the offset information to correct cutting parameters. The system continuously monitors position through detection references and adjusts cutting operations based on measured deviations, creating a closed-loop feedback system that maintains high cutting accuracy while managing process complexity through systematic error compensation.
2Measurement precision
If offset distance calculation and compensation are implemented, then cutting accuracy is improved, but the measurement and calculation complexity increases
Solution Approach 1:
The patent uses detection reference points as intermediaries between the cutting position and the measurement system. These reference points serve as mediating elements that facilitate offset distance calculation by providing known reference locations against which actual positions can be compared. The intermediaries simplify the measurement process by breaking down the complex task of direct position measurement into manageable reference-based comparisons, thereby improving positioning accuracy while controlling measurement complexity.
3Manufacturing precision
If accurate cutting time point calculation is performed based on actual distance, then cutting positioning accuracy is improved, but the calculation process becomes more complex
Solution Approach 1:
The patent applies preliminary action by pre-calculating the actual distance from the detection reference to the cutting position using offset compensation, and determining the optimal cutting time point before the cutting operation begins. This advance calculation allows the control system to prepare precise timing parameters in advance, improving cutting positioning accuracy while managing control complexity through systematic pre-computation of cutting parameters.

AI summary
A electrode plate cutting method includes: obtaining an offset distance between a detection reference and a cutting position on an electrode plate; obtaining, based on the offset distance and a distance between the detection reference and a cutting device, an actual distance between the cutting position and the cutting device; and obtaining, based on the actual distance, a cutting time point for the cutting position to be conveyed to the cutting device, so that the cutting device cuts at the cutting position. Obtaining the offset distance between the detection reference and the cutting position of the electrode plate is equivalent to obtaining a deviation from the detection reference caused during transferring of the electrode plate.
