Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired charging connections are used to physically connect the energy storage device to a stationary power supply, then reliable power transfer is achieved, but the system becomes cumbersome and poses safety risks
Solution Approach 1:
The patent extracts the physical connection requirement by using electromagnetic induction to transfer power wirelessly. The charging system removes the need for cables and physical connectors, allowing the vehicle to be charged without direct contact with power supply equipment, thereby improving convenience while maintaining reliability through controlled electromagnetic coupling.
Solution Approach 2:
The patent introduces an electromagnetic field as an intermediary medium between the power supply and the energy storage device. Instead of direct physical contact, power is transferred through a magnetic coupling field generated by the charging system, which eliminates safety risks associated with exposed connectors and cables while ensuring reliable power transfer.
2Ease of operation
If wireless charging connections using antennas are used to connect to the energy storage device, then charging convenience is improved, but energy transfer efficiency degrades and losses increase
Solution Approach 1:
The patent replaces the traditional antenna-based electromagnetic wave transmission with a magnetic coupling system. Instead of using high-frequency electromagnetic waves that suffer from atmospheric loss and interference, the system uses controlled magnetic fields for inductive coupling, which significantly reduces energy loss and improves transfer efficiency while maintaining wireless convenience.
3Power
If traditional stationary charging systems are used, then power supply capability is sufficient, but the system complexity and safety risks increase
Solution Approach 1:
The patent employs a dynamic magnetic coupling system where the charging parameters can be adjusted in real-time based on the vehicle's energy storage device status. The system dynamically controls the magnetic field strength and coupling parameters to optimize power transfer, reducing system complexity by eliminating fixed infrastructure requirements while maintaining sufficient power supply capability.
