Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If solar charge controllers are equipped with built-in modems and soft SIM for two-way communication, then remote monitoring and control capabilities are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the modem and soft SIM directly into the solar charge controller unit, merging communication functionality with the existing charge control functions. This integration allows remote monitoring and control capabilities to be added without requiring separate communication devices, thereby improving ease of operation while managing device complexity through functional consolidation.
2Measurement precision
If meteorological data integration is implemented in solar charge controllers, then weather prediction accuracy and charging optimization are improved, but measurement and data processing requirements increase
Solution Approach 1:
The solar charge controller is designed to perform multiple functions: traditional charge control, meteorological data collection, solar irradiance measurement, and weather prediction. By making the device universal and multi-functional, the system can integrate diverse data types (meteorological and solar data) and process them together to improve weather prediction accuracy without requiring entirely separate specialized equipment.
Solution Approach 2:
The system implements feedback mechanisms where collected meteorological and solar data are continuously processed to optimize charging parameters and improve weather predictions. The feedback loop allows the controller to adjust charging strategies based on real-time environmental conditions and learned patterns from historical data, thereby improving measurement precision and prediction accuracy while managing data processing requirements through iterative optimization.
3Productivity
If cloud storage and data transmission capabilities are added to solar charge controllers, then energy management optimization is improved, but energy consumption and communication infrastructure requirements increase
Solution Approach 1:
The system implements partial data transmission by selectively sending only critical or aggregated energy management data to cloud storage, rather than continuously transmitting all collected data. This approach allows energy management optimization through cloud-based analysis while minimizing the energy consumption associated with frequent data transmission and reducing the burden on communication infrastructure.
