Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If radio wave intensity threshold determination is used to detect loading work, then the system can automatically determine loading status, but the measurement precision of load detection deteriorates leading to inaccurate total load calculation
Solution Approach 1:
The patent introduces an intermediary verification mechanism using multiple detection methods (radio wave intensity, approach detection, withdrawal detection) to mediate between automatic determination and accurate measurement. The control unit cross-references multiple data sources to verify loading work occurrence, ensuring both automation and precision in load detection.
2Device complexity
If only radio wave intensity and threshold values are used for determination, then the device complexity is reduced, but the reliability of load verification deteriorates
Solution Approach 1:
The system implements feedback mechanisms where the control unit continuously monitors radio wave intensity changes, approach/withdrawal events, and loading work determinations. This feedback loop allows the system to verify loading work through multiple independent checks, enhancing reliability without significantly increasing device complexity.
3Productivity
If the system determines loading work based on radio wave intensity threshold, then productivity is improved through automated monitoring, but the loss of information occurs when loading work is not actually implemented despite threshold met
Solution Approach 1:
The system performs preliminary detection actions by monitoring radio wave intensity changes and detecting approach/withdrawal events before finalizing loading work determination. This preliminary action allows the control unit to anticipate and verify actual loading work occurrence, preventing information loss about true loading status while maintaining automated monitoring productivity.

AI summary
The present disclosure provides a construction management system capable of ascertaining information about a construction site more accurately than before. A construction management system 100 comprises: a position sensor 16a detecting position information about a transport vehicle 10 that transports payload; a position sensor 26 detecting position information about a loading machine 20 that loads payload onto the transport vehicle 10; a weight detection device 120 detecting weight information about the payload held by the loading machine 20; and an information management controller 130 which, based on chronological information of the position information about the transport vehicle 10, chronological information of the position information about the loading machine, and chronological information of the weight information, calculates the load weight of the payload loaded onto the transport vehicle 10.
