Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current landslide monitoring methods face limitations in accurately measuring deep geological parameters due to a lack of suitable monitoring instruments and low coupling between monitoring data, leading to inefficiencies, high costs, and poor correlation.
Innovation Solution
An arrangement device for integrated sensors at a deep position of a sliding mass, comprising a monitor with a casing pipe and sensor integrated probes, along with a monitoring system that includes a driving mechanism and propelling portion to automate the insertion of sensors into boreholes, allowing for multi-parameter monitoring with reduced environmental disturbance and enhanced accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple independent monitoring instruments are distributed in the sliding mass, then monitoring coverage is improved, but installation complexity and cost increase significantly
Solution Approach 1:
The patent combines multiple independent monitoring instruments (displacement sensors, seepage sensors, stress sensors) into a single integrated sensor assembly that can be installed together through one borehole, reducing the number of separate installations while maintaining comprehensive monitoring coverage
Solution Approach 2:
The integrated sensor assembly serves multiple monitoring functions simultaneously (displacement, seepage, stress measurement) through a single device structure, making the system multi-functional and reducing the need for multiple separate instruments
2Measurement precision
If multiple independent monitoring instruments are distributed in the sliding mass, then monitoring coverage is improved, but installation cost increases
Solution Approach 1:
By merging multiple instruments into one integrated assembly, the patent reduces the total number of boreholes needed and minimizes installation labor, directly lowering installation costs while maintaining comprehensive monitoring coverage
3Device complexity
If traditional monitoring methods are used, then equipment simplicity is maintained, but data correlation and coupling are poor
Solution Approach 1:
The integrated sensor assembly physically combines multiple measurement functions in close proximity, enabling the system to capture correlated data from different parameters (displacement, seepage, stress) simultaneously, thereby improving data correlation while maintaining relatively simple equipment structure
4Ease of operation
If manual sensor installation is used, then operation simplicity is maintained, but efficiency is low and environmental disturbance is high
Solution Approach 1:
The sensor assembly is pre-assembled and integrated before installation into the borehole, allowing for efficient bulk installation of multiple sensors simultaneously, thereby improving productivity while maintaining operational simplicity through standardized procedures
5Measurement precision
If more sensors are deployed to improve monitoring accuracy, then measurement precision is improved, but environmental disturbance increases
Solution Approach 1:
By combining multiple sensors into a single integrated assembly installed through one borehole, the patent achieves comprehensive monitoring accuracy while minimizing environmental disturbance by reducing the total number of boreholes and installation points required
