Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a laser detector is used to detect height differences for calibration, then calibration can be performed, but the system cost increases and the calibration system becomes more complex
Solution Approach 1:
The patent replaces the mechanical/optical laser detector system with an image recognition system using a camera or smartphone. The image recognition device captures images of the target plate with laser lines, and software algorithms process these images to determine laser position and calculate height differences, eliminating the need for specialized laser detection hardware.
Solution Approach 2:
The patent uses image capture to create a visual copy of the laser pattern on the target plate. Instead of directly measuring laser position with a detector, the system captures an image of the laser lines on the target and processes this visual copy to extract measurement information, reducing hardware requirements.
2Adaptability or versatility
If a fixed distance calibration method is used, then calibration can be performed, but the calibration system lacks flexibility and adaptability
Solution Approach 1:
The patent introduces a rotatable laser level that can be rotated by a controlled angle around a vertical axis. This dynamic capability allows the laser to project lines at different angles onto the target plate, enabling multiple measurement configurations and improving system flexibility while maintaining calibration accuracy through angular variation.
Solution Approach 2:
The patent adds the angular dimension to the calibration process by rotating the laser level. Instead of only measuring at fixed distances along a straight line, the system now operates in two dimensions (distance and angle), allowing calibration from multiple perspectives and improving adaptability to different calibration scenarios.
3Ease of operation
If specialized calibration equipment is used, then calibration accuracy can be maintained, but the ease of operation decreases and user accessibility is reduced
Solution Approach 1:
The patent uses a smartphone or camera as the image recognition device, which are universal devices already owned by most users. This multi-functional approach allows the same device to serve both as a capture tool and as a processing unit, eliminating the need for specialized calibration equipment while maintaining ease of operation.
Solution Approach 2:
The system allows users to perform calibration themselves using their own smartphones or cameras. The image recognition software automatically processes the captured images, calculates laser positions and height differences, and provides calibration results without requiring professional equipment or expert operation, enabling end-users to conduct their own calibration.

AI summary
A device for calibrating a laser level includes a base platform, a target, and an image recognition device. The base platform is configured to support the laser level that is to be mounted on the base platform at a first position. The target is arranged at a second position of the base platform and configured to receive a laser. The image recognition device is configured to obtain images of lasers projected on the target before and after the laser level rotates a first angle, determine, based on an image recognition result of the images, positions of the lasers emitted by the laser level to determine a deviation distance, and determine whether the laser level needs to be calibrated based on the deviation distance. The deviation distance is determined by position data of the first position and the second position, and the first angle.
