Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If compaction management is based only on compaction time, then the system is simple to operate, but the compaction pressing force cannot be accurately managed
Solution Approach 1:
The patent replaces simple time-based management with a sensor-based measurement system that detects compaction pressing force. Pressure sensors mounted on the compaction device directly measure the force applied to the ground, substituting mechanical estimation with precise electronic measurement.
Solution Approach 2:
The patent introduces a management server as an intermediary that collects data from multiple compaction devices, calculates compaction states, and provides standardized management. This intermediary layer integrates complex measurements while keeping individual device operations simple.
2Device complexity
If compaction management tracks only the number of passes, then the system requires minimal sensors, but the target compaction pressing force cannot be judged
Solution Approach 1:
The patent replaces pass-counting methods with direct force measurement using pressure sensors. This substitution enables precise monitoring of compaction pressing force at each location, ensuring quality consistency without significantly increasing system complexity.
Solution Approach 2:
The patent implements feedback mechanisms where compaction state information is transmitted to a management server, which can provide guidance on whether target compaction has been achieved. This feedback loop ensures quality control while maintaining reasonable system complexity.
3Loss of information
If multiple compaction pressing records are stored for each position, then the data is comprehensive for analysis, but the system complexity and data management burden increase
Solution Approach 1:
The patent introduces a management server as an intermediary that handles the complexity of storing and processing multiple compaction records. The server consolidates data from multiple devices, manages the comprehensive information, and presents processed results, shielding individual devices from data management complexity.
Solution Approach 2:
The management server performs multiple functions: collecting data from various devices, storing comprehensive records, calculating compaction states, and providing management information. This universal system handles data complexity centrally while keeping individual device operations simple.

AI summary
Provided is a compaction management system capable of accurately managing the compaction state of a compaction target ground. The compaction management system includes a compaction-pressing-record production unit, a storage device, and a final-compaction-pressing-record selection unit. The compaction pressing record production unit produces a plurality of compaction pressing records, each of which includes the pressing compaction position and the compaction pressing force which are associated with each other. The storage device stores the plurality of compaction pressing records. The final-compaction-pressing-record selection unit selects a selection target compaction pressing force record including the largest compaction pressing force among a plurality of selection target compaction pressing records, which are included in the plurality of compaction pressing records stored in the storage device and produced with respect to the same compaction pressing position, as the final compaction pressing force record with respect to the compaction pressing position.
