Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for identifying contamination sources in subsurface terrain are inefficient, often failing to detect leaks before they reach groundwater, leading to costly and time-consuming cleanup efforts and posing risks to human health and aquatic life.
Innovation Solution
A drone-type device equipped with sensors and a ground penetrating radar is deployed to navigate subsurface terrain, measure pollutant concentrations, and determine the source by analyzing concentration gradients, allowing for early detection and prevention of groundwater contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional ground-level methods are used to identify contamination sources, then the detection process is simple and low-cost, but the detection accuracy is low and contamination sources are often missed
Solution Approach 1:
The patent transitions from ground-level two-dimensional detection to subsurface three-dimensional detection by deploying a drone-type device that can navigate through vertical and horizontal subsurface spaces, enabling detection in previously inaccessible dimensions and significantly improving contamination source identification accuracy
Solution Approach 2:
The drone-type device serves as an intermediary between ground-level observation and subsurface contamination sources, equipped with sensors and sampling compartments that act as mediators to detect and collect contamination data from difficult-to-reach subsurface environments
2Reliability
If groundwater is allowed to flow naturally without monitoring, then the system remains simple, but contamination risks to human health and aquatic life increase
Solution Approach 1:
The system performs preliminary detection by deploying the drone-type device upstream or at strategic locations before contamination can spread to groundwater sources, enabling early identification and intervention before contamination reaches critical levels, thus improving both safety and remediation efficiency
3Measurement precision
If extensive sampling and analysis are conducted to ensure accurate contamination source identification, then detection accuracy improves, but time consumption and operational complexity increase
Solution Approach 1:
The patent replaces extensive mechanical sampling and laboratory analysis with electronic sensors that directly measure pollutant concentrations in real-time, substituting time-consuming physical processes with rapid electronic detection methods while maintaining or improving measurement accuracy
Solution Approach 2:
The drone-type device continuously samples and measures pollutant concentrations along its navigation path, providing uninterrupted real-time data rather than discrete periodic measurements, which improves detection accuracy while reducing total detection time through continuous monitoring
