Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired charging connections are used to charge the energy storage device, then the vehicle can be charged at stationary locations, but the system becomes cumbersome and poses safety risks due to physical connections
Solution Approach 1:
The patent extracts the direct electrical connection component from the charging system by using the vehicle's existing power generation device (such as the motor acting as a generator during regenerative braking) to charge the energy storage device. This eliminates the need for external charging cables and connectors, thereby removing the safety risks and complexity associated with physical wired connections while maintaining the charging function.
2Ease of operation
If wireless charging connections are used to charge the energy storage device, then the charging process becomes more convenient, but energy transfer efficiency degrades due to transmission losses
Solution Approach 1:
The patent implements self-service charging by utilizing the vehicle's own power generation capabilities (such as regenerative braking energy) to charge the energy storage device. This internal energy recycling eliminates the need for external wireless power transmission, thereby maintaining charging convenience while avoiding the energy transfer losses inherent in wireless charging systems.
3Use of energy by moving object
If direct electrical connections are used for charging, then power transfer is efficient, but safety risks increase due to exposure to electrical components
Solution Approach 1:
The patent removes the external electrical connection interface by using the vehicle's internal power generation device to charge the energy storage system. This extraction of the external connection point eliminates exposure to electrical components and associated safety hazards while maintaining efficient energy transfer through the vehicle's existing electrical architecture.
4Reliability
If stationary charging systems are used, then the vehicle can be charged at fixed locations, but the system becomes inconvenient and cumbersome to operate
Solution Approach 1:
The patent transforms the static charging model into a dynamic one by enabling the vehicle to charge itself during operation through regenerative braking and other power generation modes. This dynamic self-charging capability eliminates the need for fixed charging locations and manual connection operations, thereby improving convenience while maintaining charging availability through continuous operation-based charging.
