Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If foundation monitoring systems are installed to detect structural changes, then structural safety and reliability are improved, but device complexity and installation cost increase
Solution Approach 1:
The monitoring system is divided into multiple independent sensor nodes, each capable of autonomous operation. Each node contains its own processor, energy storage unit, and wireless communication module, allowing distributed monitoring without requiring a centralized complex system architecture.
Solution Approach 2:
Each sensor node is equipped with an energy storage unit and processor that enable autonomous operation. The nodes automatically monitor foundation tilt, process data locally, and transmit warnings without requiring continuous external power or manual intervention, reducing overall system complexity.
2Reliability
If real-time monitoring is implemented to detect foundation tilt, then early damage detection capability is improved, but energy consumption increases
Solution Approach 1:
The sensor nodes perform periodic tilt measurements rather than continuous monitoring. The processor activates the inclination sensors at intervals, processes the data, and only transmits warnings when threshold values are exceeded, significantly reducing energy consumption while maintaining early detection capability.
Solution Approach 2:
Each node contains an energy storage unit that provides autonomous power supply. The processor intelligently manages energy usage by activating sensors only when needed for periodic measurements and controlling wireless communication based on data thresholds, optimizing energy efficiency.
3Measurement precision
If inclination sensors are used to measure foundation orientation, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent extracts only the essential function of measuring tilt orientation using inclination sensors, removing unnecessary complex components. Each node focuses solely on measuring foundation tilt relative to gravitational acceleration, process the data, and transmit warnings, simplifying the overall system while maintaining measurement precision.
4Reliability
If wireless communication modules are added for data transmission, then real-time alert capability is improved, but device complexity and power requirements increase
Solution Approach 1:
The system extracts only the essential communication function - transmitting tilt warning data when thresholds are exceeded. The wireless communication module is integrated into each simple sensor node without requiring complex network infrastructure, enabling real-time alerts while maintaining device simplicity.
