Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual readings are taken at each site, then measurement accuracy is maintained, but installation complexity and operational difficulty increase, especially at remote and dangerous locations
Solution Approach 1:
The system performs self-measurement through automated sensors that continuously monitor soil deformation without requiring manual intervention. The sensors automatically detect pressure changes and transmit data, eliminating the need for operators to visit remote sites manually while maintaining measurement accuracy.
Solution Approach 2:
Manual mechanical measurement systems are replaced with automated electronic sensors and communication systems. Pressure sensors embedded in the ground automatically detect deformation and transmit data electronically, replacing the need for manual readings and reducing operational difficulty at remote locations.
2Productivity
If manual readings are taken, then system simplicity is maintained, but data collection becomes temporally sparse and costly
Solution Approach 1:
The system provides continuous monitoring through permanently installed sensors that operate continuously without interruption. The automated sensor network maintains constant surveillance of soil deformation, eliminating temporal gaps in data collection that occur with manual readings and providing continuous, temporally dense data.
Solution Approach 2:
Sensors are pre-installed and configured at the site before construction begins, enabling immediate and continuous data collection from the start. This preliminary setup eliminates the need for repeated manual visits and ensures continuous monitoring throughout the construction lifecycle, improving productivity while reducing time loss.
3Measurement precision
If sensors are installed deeply in the ground, then measurement accuracy improves, but installation difficulty and time requirements increase
Solution Approach 1:
The monitoring system is divided into modular sensor units that can be independently installed at different depths and locations. Each sensor module is self-contained with integrated power and communication, allowing parallel installation multiple units simultaneously without requiring sequential deep-boring operations, thus reducing installation time while maintaining measurement precision.
Solution Approach 2:
The system uses pressure sensors that measure soil deformation through pressure changes in the surrounding soil mass, allowing accurate measurement at depth without requiring direct physical access. This parameter-based measurement approach enables precise settlement monitoring while simplifying installation compared to traditional mechanical measurement methods at depth.
4Productivity
If automated sensors are used, then data collection efficiency improves, but initial system complexity and cost increase
Solution Approach 1:
The sensor system is designed with multi-functional capabilities, where each sensor unit performs multiple functions including pressure measurement, temperature monitoring, and data transmission through a single integrated device. This universality reduces the number of separate components needed, simplifying the overall system while maintaining high data collection efficiency and productivity.
