Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual calibration methods are used for the AA chuck and carrying table, then the calibration process can be performed, but the calibration efficiency is low and the calibration accuracy is poor
Solution Approach 1:
The patent replaces manual mechanical calibration operations with an automated optical measurement system. A laser emitter projects laser lines onto the AA chuck and carrying table, and a camera captures the reflected light to automatically calculate levelness and height data, eliminating manual measurement tools and operations.
Solution Approach 2:
The patent introduces reflective devices (such as reflective plates or mirrors) as intermediaries between the laser emitter and the measurement system. These reflective devices enhance the reflection of laser lines, improving the quality of captured images and the accuracy of automated calculations for levelness and height.
2Ease of operation
If manual calibration operations are performed, then calibration can be completed, but the process is cumbersome and time-consuming
Solution Approach 1:
The system performs self-calibration through automated image capture and processing. The camera automatically captures laser line images, and the control system automatically calculates levelness and height data without requiring operator intervention in the measurement and calculation processes, significantly reducing calibration time and operational complexity.
Solution Approach 2:
The patent positions the laser emitter and camera in predetermined locations and configures the optical paths in advance. The system is pre-set with the necessary measurement parameters and calculation algorithms, enabling rapid automated calibration when operation is initiated without requiring manual setup during the calibration process.

AI summary
A level correction system includes a first adjustment device, a chuck device provided on the first adjustment device, a first reflective device provided on the chuck device, a second adjustment device, a carrying table provided on the second adjustment device, a second reflective device provided on the carrying table, a laser emitter configured to emit incident laser light, a laser receiver, and a controller. The first reflective device and the second reflective device are used to reflect the incident laser light to form a reflected laser light. The laser receiver is used to receive the reflected laser light. The controller is used to determine a height of the chuck device or the carrying table and whether a center point of a reflected light spot formed by the reflected laser light is offset from a center point of an incident light spot formed by the incident laser light.
