Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If solar charge controllers are equipped with communication modules for two-way data exchange, then remote monitoring and optimization capabilities are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple communication functions (cellular modem with soft SIM, Bluetooth module, GPS antenna) into a single integrated communication unit within the solar charge controller. This merging approach enables comprehensive two-way data exchange, remote monitoring, and meteorological data integration while managing device complexity through unified architecture rather than separate distributed modules.
Solution Approach 2:
The communication module is designed to perform multiple functions simultaneously: two-way data exchange between controller and user, cloud storage connectivity for optimization algorithms, GPS location tracking, and integration with meteorological services. This multi-functionality reduces the need for separate dedicated devices and improves overall system efficiency.
2Productivity
If solar charge controllers integrate meteorological data processing, then charging optimization is improved, but device complexity and power consumption increase
Solution Approach 1:
The system retrieves meteorological data (temperature, humidity, solar irradiation) in advance from cloud-based meteorological services and uses this pre-acquired data to predict optimal charging parameters before actual charging occurs. This preliminary data gathering and processing allows the controller to proactively adjust charging algorithms based on forecasted conditions rather than reacting to real-time changes, improving efficiency while reducing continuous sensing power consumption.
Solution Approach 2:
The controller implements a feedback mechanism where charging performance is continuously monitored and compared against predictions made using meteorological data. The system adjusts charging parameters based on this feedback loop, optimizing battery charging efficiency while adapting to changing environmental conditions. The feedback system uses historical data to refine future predictions, reducing the need for high-power continuous monitoring.
3Adaptability or versatility
If solar charge controllers use soft SIM for communication, then device portability and flexibility are improved, but reliability of communication connection may be reduced
Solution Approach 1:
The soft SIM technology allows the communication module to dynamically change network parameters such as SIM card identifiers, authentication credentials, and network registration details through software updates rather than physical hardware changes. This enables flexible adaptation to different cellular networks and regions while maintaining reliable communication by allowing remote provisioning and reconfiguration of communication parameters without requiring physical SIM card replacement or device reassembly.
