Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If laser cutting is performed without coordinate correction, then the processing speed is maintained, but the manufacturing precision deteriorates due to misalignment between actual and target processing lines
Solution Approach 1:
The patent implements feedback by detecting the actual processing line after laser cutting, comparing it with the target processing line, and calculating coordinate correction values. This closed-loop feedback system continuously adjusts the scanner coordinates to minimize misalignment, thereby improving manufacturing precision without requiring complex hardware modifications.
Solution Approach 2:
The patent replaces complex mechanical adjustment mechanisms with a computational coordinate correction system. Instead of physically adjusting the laser apparatus or scanner positioning mechanisms, the system uses software-based coordinate transformation and correction algorithms to achieve precise alignment, thereby improving precision while maintaining system simplicity.
2Manufacturing precision
If coordinate correction is implemented, then the manufacturing precision is improved, but the loss of time increases due to additional detection and correction steps
Solution Approach 1:
The patent applies preliminary action by performing coordinate correction on previously detected actual processing lines and storing the correction values. These pre-calculated correction values are then applied to subsequent cutting operations, eliminating the need to perform detection and correction for every single cut, thereby reducing time loss while maintaining high precision.
Solution Approach 2:
The patent changes the parameter of coordinate values by detecting deviations between actual and target processing lines, calculating correction amounts, and applying these parameter changes to the scanner coordinate system. This dynamic parameter adjustment enables precise cutting while minimizing time loss through efficient correction algorithms.
3Loss of substance
If substrate wastage is reduced through precise cutting, then the loss of substance decreases, but the device complexity increases due to coordinate correction mechanisms
Solution Approach 1:
The patent uses feedback to detect actual processing lines, compare them with target lines, and calculate coordinate corrections that minimize substrate wastage. This feedback-driven coordinate correction ensures precise cutting along the intended path, reducing material waste without requiring complex physical modifications to the laser apparatus.
Solution Approach 2:
The patent substitutes complex mechanical positioning and adjustment systems with a software-based coordinate correction approach. By using computational methods to calculate and apply correction values to the scanner coordinates, the system achieves precise cutting that minimizes substrate wastage while keeping the overall device complexity low.
