Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If three-dimensional data of the entire construction site is updated frequently, then the accuracy and real-time monitoring capability are improved, but the data processing time and system load increase
Solution Approach 1:
The construction site is divided into multiple regions, with focus regions receiving frequent updates and non-focus regions updated less frequently. This segmentation allows the system to maintain high accuracy for important areas while reducing overall processing time and system load.
Solution Approach 2:
Instead of updating the entire construction site uniformly, the system applies partial updates only to specific focus regions where changes are most critical. This partial action approach maintains necessary accuracy while significantly reducing the time and computational resources required.
2Loss of information
If the entire construction site is monitored in detail, then the completeness of information is improved, but the complexity of the display system increases
Solution Approach 1:
The display system applies different quality levels to different regions of the construction site. Focus regions are displayed with high detail and completeness, while non-focus regions are displayed with lower detail. This local quality approach ensures critical information is complete while reducing overall system complexity.
Solution Approach 2:
The display system segments the construction site into focus and non-focus regions, allowing different information completeness levels and display complexities for each segment. This enables the system to maintain information completeness where needed without uniformly increasing system complexity across the entire site.
3Speed
If three-dimensional data is updated in real-time across the whole site, then the timeliness of construction monitoring is improved, but the data transmission and processing load increases
Solution Approach 1:
The system extracts and prioritizes updates for focus regions, separating them from non-focus regions. This extraction allows real-time monitoring of critical areas with high timeliness while reducing the overall data transmission load by excluding less critical regions from frequent updates.
Solution Approach 2:
The system applies real-time updates partially, only to focus regions where timeliness is most critical. This partial real-time action maintains high monitoring speed for important areas while significantly reducing the data transmission and processing load compared to updating the entire site.

AI summary
A display system includes: a three-dimensional data storage unit that stores three-dimensional data indicating a three-dimensional shape in a first range of a construction site in which a work machine operates; a detection data acquisition unit that acquires detection data indicating a three-dimensional shape in a second range that is a part of the first range; an update unit that updates a partial range of the three-dimensional data on the basis of the detection data; and a display control unit that causes a display apparatus to display an updated range and a non-updated range in different display forms in the three-dimensional data.
