Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional weather forecasting systems use large amounts of data transmitted from satellites to ground stations with complex models on powerful computers, then forecast accuracy is improved, but infrastructure requirements and resource consumption increase substantially
Solution Approach 1:
The system segments the forecasting function between satellite (data collection and initial processing) and mobile device (model execution). The satellite transmits only essential initialization data rather than complete datasets, while the mobile device runs simplified models locally, dividing the complex infrastructure into distributed, lightweight components.
Solution Approach 2:
The invention extracts the core forecasting capability from centralized ground stations and embeds it directly into mobile devices. By taking out the model execution function from powerful central computers and placing it in mobile devices, the system eliminates the need for complex ground infrastructure while maintaining forecast functionality.
2Loss of information
If traditional systems transmit large amounts of atmospheric data continuously from satellites to ground stations, then complete weather information is available, but bandwidth consumption and data transmission requirements increase
Solution Approach 1:
The system extracts only the essential initialization parameters needed for forecasting from the complete satellite dataset. Instead of transmitting all atmospheric data, the satellite sends a condensed set of initial conditions that contain the critical information required for the mobile device to generate accurate forecasts independently.
Solution Approach 2:
The satellite performs preliminary data processing and condensation of atmospheric observations into compact initialization formats before transmission. This preliminary action reduces the data volume significantly while preserving the essential weather information needed for forecasting, eliminating the need for continuous large-scale data transmission.
3Measurement precision
If weather forecasting models are run on powerful ground station computers, then computational accuracy is maintained, but portability and accessibility to mobile devices are reduced
Solution Approach 1:
The forecasting system is segmented into data collection (satellite) and model execution (mobile device) components. By dividing the system this way, the mobile device can run simplified forecasting models with sufficient accuracy for practical applications, making weather forecasting accessible anywhere with satellite connectivity without requiring ground station infrastructure.
4Measurement precision
If complete atmospheric datasets are transmitted to enable accurate forecasts, then forecast quality is improved, but data transmission time and bandwidth requirements increase
Solution Approach 1:
The system extracts and transmits only the critical initialization parameters required for forecast generation rather than complete atmospheric datasets. This extraction approach maintains forecast quality by preserving essential weather state information while reducing transmission time and bandwidth requirements by orders of magnitude.
