Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for checking rotating lasers for cone errors are not adaptable to indoor environments and are not fully automated, relying on predefined measurement distances and manual alignment, which can lead to inaccuracies and operator-dependent results.
Innovation Solution
A method that positions the rotating laser between two measurement surfaces with adjustable measurement distances, using a laser receiver to determine the incident positions of the laser beam and calculate cone errors, allowing for automated execution and independence from operator care, with the ability to adapt to ambient conditions through motorized height adjustment and auto-alignment functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If predefined measurement distances are used for cone error checking, then the checking procedure is standardized and easy to follow, but the method cannot be adapted to indoor environments or various ambient conditions
Solution Approach 1:
The measurement distances D1 and D2 are made variable and adaptable rather than fixed. The method allows the rotating laser to be positioned at different distances from the measurement surface depending on the application environment, with the cone error calculation adjusted accordingly using the specific distance values in the formula tan(δ) = (H1-H2)/(2*(D1-D2))
Solution Approach 2:
The measurement parameters (distances D1, D2 and height offsets H1, H2) are changed and optimized for different environments. The method uses the actual measured distances rather than predefined values, allowing adaptation to indoor and outdoor conditions while maintaining accuracy through parameter-specific calculations
2Measurement precision
If manual alignment and marking of laser beam positions are used, then simple equipment is required, but the results become operator-dependent and less accurate
Solution Approach 1:
Manual mechanical marking and measuring operations are replaced with an automated optical-electronic system. The laser receiver automatically detects the laser beam positions, and the evaluation device calculates the height offsets H1 and H2 and subsequently the cone error δ, eliminating manual intervention and operator-dependent variability
Solution Approach 2:
The system performs self-measurement and self-evaluation. The laser receiver automatically tracks the laser beam incident positions on the measurement surface, and the evaluation device autonomously computes the cone error from the measured parameters without requiring operator skill or manual alignment procedures
3Extent of automation
If the laser receiver automatically determines incident positions and calculates height offsets, then measurement precision and automation are improved, but the device complexity increases
Solution Approach 1:
The laser receiver is designed with multi-functionality, serving both as an automated position detection device and as a reference for height offset measurement. The same device that detects laser beam positions also provides the vertical reference (zero position of detection field) needed for calculating height offsets H1 and H2, reducing the need for separate specialized equipment
Solution Approach 2:
The laser receiver acts as an intermediary between the rotating laser and the evaluation device. It automatically captures the laser beam incident positions and translates them into measurable height offsets relative to its zero position, facilitating the automated calculation of cone error without requiring direct manual measurement

Function Achieved in This Case
The method provides accurate and automated cone error checking, independent of operator skill and adaptable to various environments, ensuring the rotating laser meets accuracy requirements without the need for predefined measurement distances.
Implementation Method 1
The incident position of the laser beam is determined as a second control point by a detection field of a laser receiver and the distance of the second control point to a zero position of the detection field is stored as first height offset H1
