Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual leveling operation is used, then the device complexity is low, but the productivity is low and measurement precision is poor
Solution Approach 1:
The patent replaces manual mechanical leveling operations with an automated optical-mechanical system. The image acquisition device captures images of reflecting devices on the loading tray, the height positioning device calculates deflection values based on image coordinates, and the controller automatically adjusts the leveling parameters. This substitution of manual mechanical operation with an automated optical-detection-and-control system resolves the contradiction by significantly improving leveling efficiency while accepting increased system complexity as necessary for automation.
Solution Approach 2:
The system implements self-service leveling by automatically detecting the loading tray's level state through image acquisition and calculating deflection values, then automatically adjusting itself without requiring manual intervention. The controller receives the deflection values and autonomously controls the leveling device to adjust the loading tray until it reaches the desired horizontal state, enabling the system to perform its own leveling operation and resolve the productivity-automation contradiction.
2Manufacturing precision
If manual leveling operation is used, then the device complexity is low, but the manufacturing precision is poor
Solution Approach 1:
The patent replaces subjective manual leveling judgment with objective optical detection and computational analysis. The image acquisition device captures precise coordinates of reflecting devices, the height positioning device calculates deflection values through coordinate analysis, and the controller translates these values into precise leveling adjustments. This substitution eliminates human error and subjective judgment, achieving high manufacturing precision (leveling accuracy) through an automated optical-mechanical system.
Solution Approach 2:
The system implements a closed-loop feedback mechanism where the image acquisition device continuously monitors the loading tray's level state by capturing images of reflecting devices, the height positioning device calculates deflection values based on image coordinates, and this feedback information is fed back to the controller which adjusts the leveling device accordingly. This feedback loop ensures high precision by continuously detecting and correcting level deviations until the desired horizontal state is achieved.
3Measurement precision
If automatic leveling system is implemented, then the productivity is high and measurement precision is high, but the device complexity increases
Solution Approach 1:
The patent replaces complex manual measurement and judgment processes with an automated optical-detection-and-computation system. The image acquisition device captures images of reflecting devices on the loading tray, the height positioning device automatically calculates deflection values based on image coordinates using computational algorithms, and the controller translates these values into precise leveling adjustments. This substitution achieves high measurement precision by eliminating human error and using objective optical measurement and mathematical calculation, while the increased device complexity is justified by the significant improvement in measurement accuracy.
