Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional sensor-based monitoring systems are deployed to measure pollutant concentrations, then measurement precision is improved, but device complexity and infrastructure costs increase significantly
Solution Approach 1:
The patent replaces physical sensor-based measurement systems with an optical imaging system. Instead of using complex sensor arrays to detect pollutant concentrations, the system uses cameras to capture images of the atmosphere, and AI algorithms analyze these images to determine pollutant levels. This substitution of mechanical/sensor-based detection with optical imaging and computational analysis resolves the contradiction by maintaining measurement capability while dramatically reducing infrastructure complexity.
Solution Approach 2:
The patent creates a visual copy of the atmospheric conditions through imaging. Rather than directly measuring chemical compositions with sensors, the system captures optical representations (images) of the air quality conditions and uses AI to interpret these visual copies to infer pollutant concentrations. This copying approach enables monitoring without requiring complex physical sampling infrastructure.
2Reliability
If ground-based monitoring stations are established to provide continuous air quality data, then reliability of air quality assessment is improved, but ease of deployment deteriorates due to difficulty in remote or inaccessible areas
Solution Approach 1:
The patent replaces the need for physical ground-based monitoring stations with remote imaging systems. Instead of deploying sensor equipment to remote locations, the system uses cameras (which can be positioned on existing structures or towers) to capture atmospheric conditions over large areas including remote regions. The AI analysis of these images provides reliable air quality assessment without requiring physical presence or infrastructure in difficult-to-reach areas.
Solution Approach 2:
The patent transitions from point-based ground measurements to area-wide aerial imaging. By capturing images that cover extensive geographic regions, the system obtains air quality data across two-dimensional spatial extents rather than at single ground locations. This dimensional shift enables monitoring of remote and inaccessible areas that would be impractical to reach with traditional station-based approaches.
3Measurement precision
If manual sample analysis is performed to determine air quality, then measurement accuracy is maintained, but loss of time increases due to delayed results
Solution Approach 1:
The patent implements continuous automated monitoring through AI analysis of sequential images. Instead of periodic manual sampling and analysis, the system continuously captures images and processes them through AI algorithms to generate real-time pollutant concentration data. This continuous automated operation eliminates the time delays inherent in manual analysis while maintaining measurement accuracy through sophisticated computational methods.
Solution Approach 2:
The patent enables the system to perform its own analysis automatically without external manual intervention. The AI model processes the captured images and directly outputs pollutant concentration measurements, eliminating the need for human analysts to manually examine samples. This self-service capability accelerates the measurement process while maintaining consistency and accuracy in the results.
4Area of stationary object
If satellite-based monitoring is used to achieve broad spatial coverage, then area of coverage is improved, but productivity deteriorates due to discontinued measurements and 24-hour delays
Solution Approach 1:
The patent implements continuous monitoring by capturing images at regular intervals and processing them through AI algorithms in real-time. Unlike satellite systems that pass overhead periodically, the ground-based imaging system can continuously capture and analyze atmospheric conditions, providing uninterrupted data streams with high temporal resolution while maintaining broad spatial coverage through wide-angle imaging.
Solution Approach 2:
The patent performs preliminary processing of images through AI algorithms immediately upon capture, enabling real-time generation of pollutant concentration data. This preliminary automated analysis eliminates the delay of waiting for satellite passes and subsequent data processing, providing rapid results that can inform immediate air quality decisions while covering large geographic areas.
Data Source
AI summary
Systems and methods are disclosed for image-based monitoring of air pollution using a trained artificial-intelligence (AI) model. An image capturing unit acquires images of a field of view in at least one spectral band. The captured images are synchronized in time and location with reference measurements (e.g., from ground sensors, satellite products, or meteorological instruments) to form training dataset for the AI model. In operation, the trained AI model processes captured images to determine a pollutant concentration distribution map across the field of view and can identify emission sources by detecting spatial extrema. The system supports single or multiple cameras, including fixed, movable, or drone-mounted platforms, and may incorporate multi-band image fusion. After training, inference may be performed from images alone without real-time reference sensors. Outputs include heatmap visualizations, concentration values for gaseous species and particulate matter, alerts, and trend analyses.
