Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If post-extraction laboratory testing is used for nutrient detection, then measurement precision can be maintained, but productivity is reduced due to labor-intensive processes and lack of real-time feedback
Solution Approach 1:
The patent replaces the mechanical/chemical laboratory extraction and analysis system with a thermal sensing system that detects nutrient concentrations through temperature changes. The thermal sensor directly measures nutrient levels in the substrate without requiring physical extraction or complex laboratory equipment, thereby maintaining measurement precision while dramatically improving detection speed and enabling real-time monitoring.
Solution Approach 2:
The patent introduces a thermal sensor as an intermediary between the nutrient-containing substrate and the measurement system. The sensor acts as a mediator that converts nutrient concentration information into detectable thermal signals, enabling indirect but accurate and rapid measurement of nutrient levels without direct chemical analysis.
2Measurement precision
If frequent nutrient analysis is conducted to improve agricultural precision, then productivity and measurement precision are improved, but loss of time increases due to the cumbersome nature of traditional methods
Solution Approach 1:
The patent enables continuous nutrient monitoring by deploying thermal sensors that can continuously measure nutrient concentrations in the crop substrate. This eliminates the discontinuous, batch-processing nature of laboratory testing, allowing for uninterrupted real-time data collection that significantly reduces the time loss associated with repeated sampling and analysis cycles.
Solution Approach 2:
The thermal sensors are pre-installed in the crop substrate before nutrient deficiencies occur, allowing for continuous monitoring and early detection of nutrient changes. This preliminary positioning enables the system to detect nutrient levels in real-time without requiring repeated intrusive sampling actions.
3Reliability
If excess fertilizer is applied to ensure adequate nutrient levels, then reliability of nutrient supply is improved, but object-generated harmful factors increase due to groundwater pollution and eutrophication
Solution Approach 1:
The patent implements a real-time feedback system where thermal sensors continuously monitor nutrient concentrations in the substrate and provide data that can trigger automated fertilizer application adjustments. This closed-loop feedback mechanism ensures that fertilizer is applied only when and where needed, maintaining reliable nutrient supply while preventing the harmful effects of excess fertilizer application such as groundwater pollution and eutrophication.
