Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual monitoring methods are used to track construction machines, then detailed operation information can be obtained, but significant manpower is required and automation is insufficient
Solution Approach 1:
The patent replaces manual monitoring operations with an automated system comprising cameras, laser measuring devices, and computer processing. The camera captures images of construction machines, the laser device measures positions, and the computer automatically processes this data to track machine movements and operations, eliminating the need for manual observation and recording while providing detailed operation information.
2Loss of information
If continuous monitoring of multiple site resources is performed, then comprehensive operation situations are captured, but system complexity and processing requirements increase
Solution Approach 1:
The monitoring system is divided into separate functional modules: cameras for image capture, laser measuring devices for position measurement, and a computer for data processing. Each module performs a specific function, and they work together through standardized interfaces. This segmentation allows the system to handle multiple site resources simultaneously while keeping each component relatively simple and manageable.
Solution Approach 2:
The system uses universal components that can monitor multiple types of site resources (construction machines, workers, materials) with the same hardware setup. The camera and laser measuring device can track various objects without requiring different equipment, and the computer processing system handles diverse data types through unified algorithms, reducing overall system complexity despite comprehensive monitoring coverage.

AI summary
In order to monitor operation situations of site resources at a construction site efficiently, a measuring system uses a surveying apparatus 100 including a camera and a position-determining function using laser light, and the measuring system includes a photographing means for continuously photographing construction machines 201 to 204 which are site resources for performing operations at a construction site by the camera, a recognizing means recognizing the site resources in photographed images obtained by the photographing, a tracking means for tracking the image of the site resources recognized in the multiple photographed images obtained by the continuous photographing, and a position-determining means collimating to the site resources which are objects for the tracking, and determining the positions of site resources by the position-determining function, in which the determining of positions is performed multiple times at intervals.
