Engineering Contradiction Analysis
1Productivity
If wireless charging is performed while the battery is in an overheated state, then charging continues without interruption, but the battery temperature increases further causing safety issues and reduced battery life
Solution Approach 1:
The system continuously monitors battery temperature during wireless charging and uses this feedback to dynamically adjust or terminate charging. When the temperature exceeds a predetermined threshold, the controller stops charging, preventing further temperature increase and ensuring battery safety while maintaining optimal charging conditions.
2Reliability
If the charging pin is inserted at an angle or not fully inserted, then connection reliability is poor, but the docking connection structure remains simple without complex alignment mechanisms
Solution Approach 1:
The charging pin is designed with an asymmetric structure featuring a guide portion with specific geometric shape that corresponds to a matching recess in the docking connection. This asymmetric design provides inherent alignment guidance, ensuring the pin inserts at the correct angle and position without requiring complex alignment mechanisms, thereby improving connection reliability while maintaining structural simplicity.
3Reliability
If the charging pin has a large contact area with the anvil, then charging stability is improved, but the pin diameter increases making it more prone to bending during insertion
Solution Approach 1:
The contact area between the charging pin and anvil is segmented into multiple distributed contact points rather than a single large contact surface. This segmentation allows the pin to maintain adequate electrical contact stability while using a smaller overall pin diameter, thereby reducing the pin's susceptibility to bending during insertion while still ensuring reliable charging connection.
4Reliability
If guided insertion structures are added to prevent angled insertion, then connection reliability improves, but the device structure becomes more complex
Solution Approach 1:
The charging pin incorporates an asymmetric guide portion with a specific geometric shape that naturally guides insertion by providing a single correct orientation. This asymmetric design inherently prevents angled or incorrect insertion without requiring additional complex guided insertion structures, thereby improving connection reliability while maintaining device simplicity.

AI summary
A charging method and an apparatus are provided, and may be applied to a process in which a third-party network performs service control and/or data transmission through a network provided by an operator network, to charge a user of a bridge, and enable effective implementation of a service that needs to use the bridge. The method includes: A first network element determines first charging information, and sends the first charging information to a charging function network element, where the first charging information is for charging a third-party network for using a bridge, the first charging information includes information for identifying the bridge and information for determining a user of the bridge, the bridge includes a network-side time-sensitive networking translator NW-TT port and a device-side time-sensitive networking translator DS-TT port, the NW-TT port and the DS-TT port are separately communicatively connected to a device of the third-party network, and the NW-TT port is communicatively connected to the DS-TT port via a user plane network element and an access network device. After receiving the first charging information, the charging function network element performs charging processing based on the first charging information.
