Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional mobile charging devices are used to charge electric vehicles, then charging can be provided at locations without fixed charging stations, but the limited energy storage capacity requires multiple plugging and unplugging operations
Solution Approach 1:
The patent implements automatic docking mechanism that enables continuous charging operation between mobile charging devices and electric vehicles. The charging plug automatically connects and disconnects through docking structures, eliminating the need for manual plugging and unplugging operations while maintaining the mobility advantage of mobile charging devices.
Solution Approach 2:
The mobile charging device incorporates self-docking capability where the charging plug automatically aligns and connects with the vehicle's charging port through guide structures and positioning mechanisms. This self-service function reduces operational complexity while preserving the flexibility of mobile charging.
2Weight of moving object
If traditional mobile charging devices with limited energy storage are used, then device portability is maintained, but charging intermittency occurs requiring multiple charging sessions
Solution Approach 1:
The patent describes a system where multiple mobile charging devices can dock with each other to transfer and accumulate energy. This merging capability allows charging devices to combine their energy reserves, providing continuous charging capability while maintaining individual device portability. The docking mechanism enables energy transfer between devices, effectively extending operational duration without increasing individual device weight.
3Quantity of substance
If multiple plugging and unplugging operations are performed on electric vehicle charging ports, then limited energy storage of mobile devices is compensated, but charging port damage risk increases
Solution Approach 1:
The automatic docking mechanism ensures smooth, controlled connection and disconnection of charging plugs, eliminating abrupt mechanical stresses that could damage charging ports. The continuous operation mode reduces the frequency of plugging/unplugging cycles, thereby protecting port durability while achieving the required energy transfer quantity.
Solution Approach 2:
The docking structure incorporates cushioning elements and protective mechanisms that absorb mechanical shocks during connection and disconnection operations. This beforehand cushioning protects the charging ports from damage caused by repeated plugging and unplugging, ensuring reliable operation while maintaining energy transfer capability.
