Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual methods are used for checking and calibrating horizontal axes, then operator control is maintained, but automation capability is lost and operator error increases
Solution Approach 1:
The system performs self-calibration by automatically determining the horizontal state through reversal measurements and calculating inclination angles without requiring manual intervention. The rotating laser and laser receiver autonomously complete the calibration process, eliminating operator dependency and associated errors.
Solution Approach 2:
Manual mechanical operations are replaced by an automated optical measurement system. The controller device automatically controls the rotating laser, laser receiver, and data processing, substituting human mechanical actions with automated electronic control and computation.
2Adaptability or versatility
If a predefined measurement distance is used, then the checking method is simple, but flexibility in distance variability is lost
Solution Approach 1:
The measurement distance is transformed from a fixed predefined parameter to a variable parameter. The system can operate at any desired distance by automatically adapting the measurement process, allowing distance to be changed without affecting the calibration methodology.
Solution Approach 2:
The calibration system becomes universal and applicable at various distances. The same method and apparatus work regardless of the distance between the rotating laser and laser receiver, making the system versatile for different application scenarios.
3Measurement precision
If manual marking of control points is performed, then the process is straightforward, but measurement precision is reduced due to operator dependency
Solution Approach 1:
Manual marking operations are replaced by automated optical detection. The laser receiver automatically detects and records the positions of control points through optical measurement, eliminating manual marking and its associated precision limitations.
Solution Approach 2:
The physical act of marking control points on a measurement face is replaced by creating a digital copy of the control point positions. The laser receiver captures positional data electronically, storing precise coordinate information without requiring physical marks.
4Measurement precision
If the laser plane is adjusted manually to the center between control points, then the calibration process is simple, but accuracy is limited by operator judgment
Solution Approach 1:
The system uses feedback from the laser receiver measurements to automatically determine the horizontal state. The controller device receives positional data, calculates the inclination angle, and adjusts the laser plane accordingly, creating a closed-loop feedback system that improves accuracy.
Solution Approach 2:
Manual visual judgment and adjustment are replaced by automated calculation and control. The controller device computationally determines the correct horizontal position based on measurement data and automatically adjusts the laser plane, substituting human judgment with precise computational analysis.

AI summary
A method for checking and/or calibrating a horizontal axis of a rotating laser using a laser receiver and a controller device which is communicatively connected to the rotating laser and the laser receiver where the rotating laser emits a laser beam rotating about an axis of rotation in a laser plane. An inclination angle is ascertained using a first fitting function and a second fitting function where the inclination angle is used for the checking and/or the calibrating of the horizontal axis.
