Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users rely on traditional charging piles or charging stations to charge electric auxiliary vehicles, then charging can be performed using existing infrastructure, but users face inconvenience when charging stations are far away or unavailable
Solution Approach 1:
The patent enables electric auxiliary vehicles to charge each other directly through vehicle-to-vehicle wireless power transfer. The first electric auxiliary vehicle acts as a mobile charging station for the second vehicle, eliminating the need for external charging infrastructure. This self-service approach allows users to charge anywhere, anytime, resolving the inconvenience of distant or unavailable charging stations
Solution Approach 2:
The patent transforms electric auxiliary vehicles into multi-functional devices that can both receive power and provide power to other vehicles. By equipping vehicles with dual capabilities as power recipients and power suppliers, the system creates a universal charging solution where any vehicle can serve as a charging source for others, eliminating dependency on fixed charging infrastructure
2Ease of operation
If wireless charging platforms are used to enable wireless power supply, then charging convenience is improved, but system complexity and infrastructure requirements increase
Solution Approach 1:
The patent extracts the essential wireless power transfer capability from complex fixed charging platforms and integrates it directly into portable electric auxiliary vehicles. By moving the wireless charging function from stationary infrastructure to mobile vehicles, the system eliminates the need for elaborate charging platforms while maintaining wireless charging convenience
Solution Approach 2:
The patent uses a management device as a simple intermediary to coordinate between the first electric auxiliary vehicle (power supplier) and the second electric auxiliary vehicle (power recipient). This lightweight mediation system handles authentication and power transfer coordination without requiring complex charging platform infrastructure, simplifying the overall system architecture

Data Source
AI summary
A power management system and a power management method for wireless power supply are provided. The power management system includes a first electric auxiliary vehicle, a second electric auxiliary vehicle, a management device and a wireless charging platform. When the first electric auxiliary vehicle is located within a wireless charging range of the wireless charging platform, the wireless charging platform generates a password and provides the password and a user identification code of the first electric auxiliary vehicle to the management device. The first electric auxiliary vehicle communicates with the management device according to the user identification code to receive the password from the management device and displays the password, and activates a wireless power supply function according to a verification operation of the password and the user identification code, thereby providing power to the second electric auxiliary vehicle by a wireless power supply manner.
