Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional subsurface sampling methods, such as direct push technology, are limited by low resolution site characterization, requiring iterative and time-consuming processes with minimal data collection, and lack the ability for concurrent sampling and sensing of subsurface conditions, increasing costs and time.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional direct push technology is used for subsurface sampling, then the sampling process is simplified and less subsurface material is disturbed, but the site characterization resolution remains low and data collection is time-consuming
Solution Approach 1:
The patent combines multiple functions (sampling, sensing, and detection) into a single integrated probe system. The probe simultaneously collects subsurface samples and measures environmental parameters such as temperature, conductivity, and chemical concentrations, eliminating the need for separate sampling and sensing operations.
Solution Approach 2:
The probe is designed as a multi-functional tool that performs diverse subsurface investigation tasks including core sampling, fluid extraction, and multiple types of environmental sensing (thermal, electrical, chemical) within a single device, replacing multiple specialized tools.
2Measurement precision
If samples are collected and analyzed using conventional methods, then quantitative analysis can be performed, but the process requires removing the sampling device at intervals and submitting samples to laboratories, increasing time and cost
Solution Approach 1:
The system performs self-analysis by incorporating sensors and detection capabilities directly into the probe. Environmental parameters and chemical concentrations are measured and recorded in real-time during subsurface penetration, eliminating the need to transport samples to external laboratories for analysis.
Solution Approach 2:
The patent replaces mechanical sampling and laboratory analysis processes with electronic sensing and real-time data acquisition. Sensors detect and measure subsurface conditions electronically, substituting the mechanical process of sample collection, transport, and laboratory processing with automated electronic measurement and immediate digital recording.
3Adaptability or versatility
If separate boreholes are made for sampling and sensing, then both functions can be performed, but the time and cost of subsurface investigation increases
Solution Approach 1:
The patent combines multiple functions (sampling, sensing, and detection) into a single integrated probe system. The probe simultaneously collects subsurface samples and measures environmental parameters such as temperature, conductivity, and chemical concentrations, eliminating the need for separate sampling and sensing operations.
