Engineering Contradiction Analysis
1Ease of operation
If battery-powered wireless communication modules are used, then wireless data transmission capability is achieved, but lifetime, size, weight, and pollution problems occur
Solution Approach 1:
The solar cell module serves dual functions: as an optical sensor for measuring sunlight intensity and as a power supply for the wireless communication module. This eliminates the need for separate batteries while enabling continuous operation and data transmission.
Solution Approach 2:
The system uses the available sunlight to simultaneously power the wireless communication module and provide measurement data. The solar cell module harvests energy from the environment it is measuring, creating a self-sustaining system that eliminates battery replacement needs.
2Duration of action of stationary object
If solar cell module is used as both optical sensor and power supply, then battery limitations are eliminated and continuous operation is achieved, but control of output current to maximize power output is required
Solution Approach 1:
The micro control unit continuously monitors the electrical characteristics of the solar cell module and adjusts the operating point to extract maximum power. This feedback control ensures optimal performance varying with sunlight conditions while maintaining continuous operation.
Solution Approach 2:
The system dynamically adjusts the operating parameters of the solar cell module based on varying sunlight intensity. By changing the electrical operating point according to environmental conditions, the system maximizes power extraction across different lighting conditions.
