Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the solar panel area is enlarged to increase electricity generation capacity, then the electricity generation capacity is improved, but the vehicle appearance and normal running are affected
Solution Approach 1:
The patent employs a movable solar panel that can dynamically change its state between extended and retracted positions. The control device receives vehicle state information and automatically adjusts the solar panel position: extending it when the vehicle is parked to maximize electricity generation, and retracting it when the vehicle is in use to maintain appearance. This dynamic adjustment resolves the contradiction between power generation capacity and vehicle aesthetics.
2Power
If the solar panel area is increased to improve electricity generation capacity, then the electricity generation capacity is improved, but the conversion efficiency is reduced due to lack of control
Solution Approach 1:
The patent incorporates an intelligent voltage conversion and control module that continuously monitors the solar panel's output voltage and current, and adjusts the panel's operating parameters in real-time to maintain maximum power point tracking (MPPT). This feedback control ensures that even with a large solar panel area, the system operates at optimal efficiency by dynamically adjusting to changing light conditions and load requirements, preventing energy loss.
3Power
If a large solar panel is used to increase electricity generation capacity, then the electricity generation capacity is improved, but the device complexity increases due to lack of state control device
Solution Approach 1:
The patent integrates multiple functions into a single control device that simultaneously manages the movable solar panel's position, monitors voltage and current output, performs maximum power point tracking, and controls the charging process. This multi-functional controller consolidates what would otherwise be separate complex subsystems, achieving the necessary control capabilities while minimizing overall device complexity.
4Loss of energy
If the solar charging system is added to electric vehicles to reduce power grid burden, then the power grid burden is reduced, but the safety risk increases due to lack of voltage detection and monitoring
Solution Approach 1:
The patent implements real-time voltage detection and monitoring through the intelligent voltage conversion and control module, which continuously measures the solar panel's output voltage and compares it against safe operating ranges. The system provides feedback control to prevent overcharging and abnormal voltage conditions, ensuring battery safety while enabling solar charging to reduce power grid burden.
