Soil Treatment Rod with Segmented Sensor and Injection Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soil treatment devices face challenges in accurately measuring soil contamination without interfering with decontamination agents, which can damage sensitive sensors and result in inefficient dosing of expensive decontamination agents.
Innovation Solution
The soil treatment device separates the measuring and injection sections along the soil penetration rod, with the measuring section closer to the rod tip than the injection section, reducing the risk of agent interference and enabling more accurate contamination measurement and targeted decontamination agent dosing, using a control unit to manage the injection based on real-time contamination data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the measuring section and injection section are located at the same location on the soil penetration rod, then the device structure is simplified, but the decontamination agent interferes with the contamination measurement and sensors are damaged
Solution Approach 1:
The soil penetration rod is divided into distinct functional sections: a measuring section with sensors for detecting contamination and an injection section with nozzles for delivering decontamination agents. These sections are positioned at different longitudinal locations along the rod, with the measuring section closer to the tip, to prevent interference between measurement and injection functions while maintaining a relatively simple overall device structure.
2Measurement precision
If the measuring section is positioned closer to the rod tip than the injection section, then measurement accuracy improves by avoiding agent interference, but the device requires longer rod length
Solution Approach 1:
The measuring and injecting functions are arranged along the longitudinal dimension of the soil penetration rod, with the measuring section positioned closer to the rod tip. This spatial arrangement in one dimension (longitudinal position) enables accurate measurement by avoiding decontamination agent interference while maintaining a compact overall device length suitable for practical soil treatment applications.
3Productivity
If decontamination agents are injected during downward movement of the rod, then treatment efficiency increases, but sensors are exposed to harmful agents causing damage
Solution Approach 1:
The device segments the measuring and injecting functions into separate sections positioned at different locations on the soil penetration rod. The measuring section with sensitive sensors is positioned closer to the rod tip, while the injection section with nozzles is positioned further back. This spatial segmentation allows continuous operation during downward rod movement, maintaining high treatment efficiency while protecting sensors from direct exposure to harmful decontamination agents.
