Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In surveying systems using multiple rotary laser devices, positional deviations and tilting of laser reference planes due to individual device differences and environmental changes result in bumps and uneven surfaces, making it challenging to maintain a smooth transition between overlapping laser reference planes.
Innovation Solution
A surveying system comprising multiple rotary laser devices, a photodetecting device, a coordinate position measuring device, and a control device that sets up a smoothing area where overlapping effective ranges intersect, allowing for continuous smoothing processing based on detected deviations and coordinate positions, using weighted averaging to calculate a smoothing reference plane or position, thereby ensuring a smooth transition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple rotary laser devices are used to cover a wider working area, then the coverage area is improved, but positional deviation and tilting occur between overlapping laser reference planes
Solution Approach 1:
The control device continuously monitors the positions of multiple laser reference planes and automatically adjusts them to maintain consistency across overlapping areas. This feedback mechanism eliminates the need for manual intervention and ensures that positional deviations are corrected in real-time, resolving the contradiction between wide coverage and positional accuracy.
Solution Approach 2:
The system dynamically adjusts parameters such as laser beam orientation and reference plane positioning to compensate for environmental changes and device variations. By changing these parameters automatically, the system maintains manufacturing precision across the entire coverage area even when multiple devices are operating simultaneously.
2Area of stationary object
If laser reference planes are formed by multiple rotary laser devices, then the working range is extended, but bumps occur at the borders between overlapping planes
Solution Approach 1:
The control device continuously monitors the heights of overlapping laser reference planes and automatically adjusts them to eliminate bumps at border areas. This real-time feedback ensures that the transition between planes is smooth, preventing surface irregularities while maintaining extended working range.
Solution Approach 2:
The system performs preliminary smoothing operations in the overlapping areas before finalizing the reference planes. By pre-adjusting the positions in border regions, the system prevents bump formation and ensures continuous surface smoothness across the entire working area.
3Adaptability or versatility
If photodetectors and rotary laser devices are installed on movable working machines, then operational flexibility is improved, but time-consuming operations and environmental influence increase
Solution Approach 1:
The control device operates continuously to monitor and adjust laser reference planes throughout the entire working period, from morning to evening. This continuous operation eliminates idle time and ensures that environmental changes are compensated for in real-time, maintaining operational flexibility while reducing total operation time.
Solution Approach 2:
The system automatically compensates for environmental influences such as temperature changes and vibrations without requiring external intervention. The photodetectors and control device work autonomously to maintain reference plane accuracy, reducing the need for manual adjustments and minimizing operation time.
4Manufacturing precision
If manual smoothing operations are performed to eliminate bumps, then surface accuracy is improved, but operational complexity and time requirements increase
Solution Approach 1:
The control device automatically performs smoothing operations by adjusting the laser reference planes based on real-time measurements. This self-service capability eliminates the need for manual intervention, maintaining surface accuracy while reducing operational complexity and time requirements.
Solution Approach 2:
The system replaces manual mechanical smoothing operations with automated optical and electronic control. The control device uses photodetector data to automatically adjust laser reference planes, substituting human judgment and manual operations with precise automated control, thereby reducing complexity while maintaining or improving surface accuracy.
