Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a worker manually measures and inputs the electrode loss rate, then the operation is simple and quick, but the measurement precision and reliability deteriorate because the actual consumed electrode loss rate cannot be accurately identified
Solution Approach 1:
The patent replaces the manual mechanical measurement system with an automated optical detection system. The marking apparatus uses optical sensors and cameras to automatically detect electrode positions, fracture locations, and connection tape placements, eliminating manual measurement errors and providing precise digital data for electrode loss rate calculation.
Solution Approach 2:
The patent introduces reference points as intermediary markers on the electrode that serve as mediators between the physical electrode and the measurement system. These reference points enable automated detection systems to accurately track electrode positions and movements through subsequent processes, providing a reliable basis for calculating actual electrode loss rate.
2Manufacturing precision
If reference points are marked on each reserved electrode lane part, then the positioning accuracy for subsequent processes is improved, but the device complexity increases due to the need for multiple marking machines
Solution Approach 1:
The patent combines multiple marking functions into a single integrated marking apparatus. The apparatus includes a movable marking unit that can traverse across multiple reserved electrode lane parts and mark reference points on all of them sequentially, eliminating the need for multiple separate marking machines while maintaining high positioning accuracy.
Solution Approach 2:
The patent employs a dynamic marking system where the marking unit can move along the electrode width direction to reach different reserved lane parts. This dynamic capability allows one apparatus to perform the work of multiple static marking machines, reducing system complexity while maintaining the ability to mark all necessary reference points.
3Manufacturing precision
If the marking machine moves in the width direction to mark all reserved electrode lane parts, then the manufacturing precision is improved by marking all lanes, but the productivity decreases due to the additional time required
Solution Approach 1:
The patent implements continuous marking operation where the movable marking unit traverses across all reserved electrode lane parts in a single continuous motion while the electrode moves forward. This eliminates idle positioning time between marking different lanes and maintains continuous productive action throughout the marking process.
Solution Approach 2:
The patent performs reference point marking on all reserved electrode lane parts before the slitting process divides them into separate electrodes. This preliminary action allows the marking system to work on the complete pattern electrode structure, enabling more efficient batch marking compared to marking each separated electrode individually later.
4Ease of operation
If manual input of electrode loss rate is used, then the ease of operation is maintained, but the reliability of quality control and defect analysis deteriorates because quality comparison cannot be reliably performed
Solution Approach 1:
The patent implements an automated feedback system where the marking apparatus detects electrode positions, fracture locations, and connection tape placements, then automatically calculates and provides feedback on the actual electrode loss rate. This feedback loop eliminates manual input errors and provides reliable data for quality control and defect analysis.
Solution Approach 2:
The system performs self-measurement and self-calculation of electrode loss rate without requiring external manual intervention. The automated detection and calculation system serves itself by using its own detection capabilities to generate the loss rate data, ensuring consistency and reliability in quality control processes.
