Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If photovoltaic panels are fixed on the vehicle roof, then the system is simple and stable, but the power generation capacity is limited due to space constraints
Solution Approach 1:
The patent implements a dynamic photovoltaic system where panels can be extended and retracted based on operational needs. The panels transition from a static fixed configuration to a dynamic deployable structure, allowing the system to adapt its power generation capacity according to whether the vehicle is in motion or stationary for charging.
Solution Approach 2:
The photovoltaic panels are nested within the vehicle body structure when retracted, similar to a nested doll configuration. The panels can be stored inside the vehicle chassis or roof structure and deployed outward when needed, maximizing space utilization while maintaining power generation capability.
2Power
If photovoltaic panels are extended to maximize power generation, then energy output increases, but the risk of collision with obstacles increases
Solution Approach 1:
The system incorporates sensors that continuously monitor the environment around the vehicle and provide feedback to the control system. When obstacles are detected within a predetermined distance, the sensors trigger the retraction of photovoltaic panels to avoid collision, creating a closed-loop safety mechanism that balances power generation with obstacle avoidance.
3Power
If multiple stacks of solar panels are used to increase power generation, then energy output improves, but the space required for safe operation increases
Solution Approach 1:
The photovoltaic system is divided into multiple separable stacks or modules that can be independently controlled. Each stack can be extended or retracted based on charging needs, allowing the system to achieve high power generation capacity when stationary while maintaining a compact footprint during vehicle operation.
Solution Approach 2:
The multiple panel stacks transition from a compact stored configuration during vehicle movement to an extended charging configuration when stationary. This dynamic transformation allows the system to maximize power generation area during parking/charging while minimizing the footprint during normal vehicle operation.
4Reliability
If photovoltaic charging system is added to the vehicle, then range anxiety is reduced through solar charging, but the vehicle cost increases
Solution Approach 1:
The photovoltaic system is designed to serve multiple functions: generating auxiliary power during normal operation, providing extended range through solar charging when parked, and potentially serving as a protective cover or aerodynamic element when retracted. This multi-functionality justifies the added cost by providing diverse benefits beyond单纯的充电功能.
