Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Structural foundations, particularly concrete slab foundations, face challenges in monitoring for potential failures and damage, which can lead to issues like differential settlement and uneven soil moisture affecting their stability and integrity.
Innovation Solution
A system comprising sensor nodes with inclination sensors, a data aggregator, and an irrigation controller that measures and reports tilt angles, and adjusts irrigation to mitigate foundation issues by applying targeted water application based on data analysis and topography surveys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional foundation monitoring methods are used, then foundation stability is maintained, but detection capability and response time to potential failures are insufficient
Solution Approach 1:
The system performs preliminary monitoring and detection of foundation conditions before actual failures occur. Sensor nodes continuously measure inclination, temperature, and moisture levels to identify early signs of settlement or damage, enabling preventive action before structural issues develop
Solution Approach 2:
The system establishes a feedback loop where sensor data is continuously collected, analyzed, and used to adjust irrigation operations. The data aggregator processes inclination sensor readings and provides feedback to the irrigation controller, which adjusts water application in real-time to respond to detected foundation movements or settling patterns
2Stability of the object's composition
If uniform irrigation is applied to foundations, then soil moisture is evenly distributed, but differential settlement caused by uneven soil moisture cannot be addressed
Solution Approach 1:
The system transitions from uniform irrigation to localized, differential irrigation based on actual foundation conditions. Each sensor node's data is used to control irrigation at specific locations, applying water only where needed to address local settlement or moisture deficiencies. The irrigation controller adjusts water application rates and durations for different zones based on real-time inclination sensor readings
Solution Approach 2:
The system dynamically changes irrigation parameters (water application rate, duration, and location) based on detected foundation conditions. When differential settlement is detected through inclination sensors, the system modifies irrigation parameters to apply more water to settling areas and less to stable areas, thereby adjusting soil moisture distribution to counteract settlement patterns
3Device complexity
If manual inspection methods are used, then system complexity is low, but monitoring precision and continuous detection capability are insufficient
Solution Approach 1:
The system replaces manual inspection methods with automated electronic sensing and data processing. Inclination sensors, temperature sensors, and moisture sensors continuously measure foundation conditions without human intervention. The data aggregator automatically processes sensor readings and generates irrigation control signals, eliminating the need for manual measurement and decision-making

AI summary
A system comprises a remote processing system configured to: receive an indication of change or changes in orientation of a foundation detected by one or more inclination sensors; generate, based on analyzing the change or changes in the orientation of the foundation, command to control an air bag or pneumatic system to lift one or more portions of the foundation; and transmit the command to the air bag or pneumatic system to raise the foundation.
