Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a static collection box is used to collect carbon emission gas from farmland, then gas enrichment can be achieved, but the collection box interferes with crop growth and disrupts natural environmental conditions
Solution Approach 1:
The patent replaces the static collection box with a dynamic system consisting of a movable enrichment device that can be positioned and removed without permanent installation. The device uses a support structure with adjustable legs to adapt to different terrain and crop heights, allowing gas enrichment without disrupting natural conditions or crop growth.
Solution Approach 2:
The patent introduces an intermediary enrichment device that temporarily confines gas for measurement without permanently altering the environment. The device acts as a mediator between the natural farmland environment and the measurement process, allowing gas collection while maintaining natural airflow patterns and crop growth conditions outside the enrichment zone.
2Quantity of substance
If manual sampling and storage methods are used, then gas samples can be collected, but operation nonstandardization and storage time variations affect detection accuracy
Solution Approach 1:
The patent implements an automated detection system where the enrichment device integrates both enrichment and detection functions. The gas enrichment pump automatically draws gas into the enrichment chamber, and the detection mechanism automatically measures gas concentration without manual intervention, eliminating human error and standardization issues.
Solution Approach 2:
The patent combines the enrichment function and detection function into a single integrated device. The enrichment chamber serves dual purposes: it concentrates the gas for measurement and simultaneously acts as the detection chamber, eliminating the need for separate sampling, storage, and analysis steps that introduce variability.
3Quantity of substance
If workers manually place collection boxes in dense farmland, then gas collection can be performed, but operational difficulty increases and labor intensity rises
Solution Approach 1:
The patent employs a mobile enrichment device that can be easily transported and positioned by workers without requiring entry into dense crop areas. The device's collapsible design allows it to be compact for transport and easily deployed at various locations, significantly improving operational accessibility compared to fixed collection boxes.
4Duration of action of stationary object
If collection boxes are used for long-term monitoring, then continuous observation is possible, but environmental conditions inside the box deviate from natural state
Solution Approach 1:
The patent implements periodic measurement cycles where the enrichment device is deployed, performs rapid gas enrichment and measurement, then is removed. This periodic approach allows continuous monitoring over time while ensuring that each measurement occurs under near-natural conditions, preventing the environmental deviation that occurs with long-term static box placement.

AI summary
Provided are an in-situ detection device and method for carbon emissions from farmland. The in-situ detection device includes an unmanned aerial vehicle, and landing gear. A retraction and release mechanism is arranged between the unmanned aerial vehicle and the landing gear, and the retraction and release mechanism is configured for retracting or lowering the landing gear. An enrichment hood is installed on the landing gear through a folding mechanism, and the folding mechanism can drive the enrichment hood to be unfolded or folded on the landing gear. When the unmanned aerial vehicle lowers the landing gear to a farmland gas collection point through the retraction and release mechanism, the enrichment hood is unfolded to enrich a gas at the farmland gas collection point. The landing gear is also provided with a greenhouse gas detection mechanism for detecting the gas enriched in the enrichment hood.
