Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing meteorological administrations use simple daily minimum temperature notifications for frost prediction, then the system is simple to operate, but the prediction accuracy is insufficient for precise agricultural protection
Solution Approach 1:
The system segments the frost prediction task into multiple components: data collection from multiple sensors (temperature, humidity, wind speed, precipitation, insolation), feature extraction (dew point, temperature inversion, temperature difference), model selection, and prediction. This segmentation allows each component to be optimized independently while maintaining overall system manageability.
Solution Approach 2:
The patent introduces a server as an intermediary that collects data from multiple weather observation stations, processes the data through various frost prediction models, and provides the final prediction to users. This intermediary handles the complexity of data processing and model coordination, shielding end users from system complexity while enabling accurate predictions.
2Measurement precision
If comprehensive weather observation data including temperature, humidity, wind speed, precipitation, and insolation are collected and processed through big data analysis and artificial intelligence, then the frost prediction accuracy is improved, but the device complexity and data processing requirements increase
Solution Approach 1:
The system performs preliminary actions by pre-collecting and storing comprehensive weather observation data from multiple stations, pre-processing the data to extract relevant features (dew point, temperature inversion, etc.), and pre-training multiple frost prediction models before actual prediction needs arise. This preparation reduces the complexity of real-time prediction operations.
Solution Approach 2:
The patent creates multiple frost prediction models (first, second, and third models) that can be trained on historical data and used to generate predictions. These model copies allow the system to compare results and select the most accurate prediction without requiring a single complex model to handle all scenarios.
3Reliability
If a dedicated frost prediction interface with comprehensive weather data analysis is implemented, then the agricultural protection effectiveness is improved, but the implementation cost and system complexity increase compared to existing notification systems
Solution Approach 1:
The system is designed to provide multiple functions: collecting weather data from multiple sources, storing data in databases, processing data through various models, and providing predictions. This multi-functional design consolidates what could be separate complex systems into a unified platform, improving reliability while managing complexity through integration.
Solution Approach 2:
The system incorporates feedback mechanisms by comparing actual frost events with model predictions, allowing the frost prediction models to be trained and refined using historical data. This feedback loop continuously improves prediction reliability while the system learns from past performance.
