Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual leveling operation is used to fit the molding platform with the resin vat, then the operation process is simple, but the leveling precision is low and bonding firmness cannot be guaranteed
Solution Approach 1:
The patent replaces manual mechanical leveling operations with an automated detection and adjustment system. A sensor detects the gap between the molding platform and resin vat bottom, and a control system automatically adjusts the platform position, substituting human mechanical operations with automated sensing and control mechanisms to achieve precise leveling.
Solution Approach 2:
The system performs self-leveling by automatically detecting its own positioning status and adjusting accordingly. The molding platform equipment autonomously identifies gap conditions through sensors and executes correction movements without external manual intervention, enabling the system to service itself.
2Measurement precision
If visual inspection is used to identify whether the molding platform and resin vat fit, then the operation is simple, but the inspection accuracy is low and subjective errors occur
Solution Approach 1:
The patent replaces subjective visual inspection with objective sensor-based detection. A sensor positioned near the molding platform detects the actual gap distance to the resin vat bottom, converting subjective visual assessment into objective quantitative measurement that eliminates human error and subjectivity.
Solution Approach 2:
The system implements feedback control by continuously monitoring the gap between the molding platform and resin vat through sensors. The detection results are fed back to the control system, which adjusts the platform position based on the measured deviation, creating a closed-loop control mechanism for precise positioning.
