Charging Socket Inlet Rotation for Safe Disconnect During Vehicle Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Accidental vehicle movement during charging can lead to mechanical and electrical damage due to the tight coupling between the charging inlet and connector, causing destructive separation and loss of connection.
Innovation Solution
An inlet system with a charging socket that includes supports allowing horizontal and vertical rotation of the charging socket, coupled with a switch that senses rotation to proactively disconnect the electrical connection, preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the charging connector is removably coupled to the charging inlet to enable safe electrical connection, then the electrical connection reliability is improved, but the mechanical stability deteriorates when the vehicle moves accidentally during charging
Solution Approach 1:
The charging inlet is designed with rotational freedom around a vertical axis, allowing it to dynamically adjust its orientation in response to vehicle movement. This dynamic capability enables the charging socket to rotate and follow the vehicle's motion, preventing excessive tension on the charging cable and avoiding mechanical damage while maintaining electrical connection stability
2Productivity
If the charging connector is physically separated from the charging inlet to stop charging, then the charging process can be stopped, but the response time increases and safety is compromised during accidental vehicle movement
Solution Approach 1:
The switch is pre-positioned to detect rotation of the charging socket. When rotation occurs due to accidental vehicle movement, the switch immediately triggers disconnection of the electrical connection. This preliminary detection mechanism enables rapid response without requiring physical separation of the connector, preventing mechanical damage while maintaining charging control
Solution Approach 2:
The switch provides real-time feedback on the rotational status of the charging socket. When the socket rotates beyond a certain angle, the switch detects this change and automatically triggers disconnection. This feedback mechanism ensures rapid response to accidental vehicle movement, preventing damage while maintaining safety without requiring manual intervention or physical connector separation
3Stability of the object's composition
If the charging socket is fixed in position to maintain stable connection, then the connection stability is improved, but the adaptability to vehicle movement deteriorates
Solution Approach 1:
The charging inlet is designed with rotational freedom around a vertical axis, allowing it to dynamically adjust its orientation in response to vehicle movement. This dynamic capability enables the charging socket to rotate and follow the vehicle's motion, preventing excessive tension on the charging cable and avoiding mechanical damage while maintaining electrical connection stability

AI summary
An inlet system comprises a first support configured to hold a charging socket and including at least one first guide pin portion, a second support configured to rotatably hold the first support in a horizontal plane and allow the first support to rotate horizontally according to movement of the charging socket, and a switch positioned near at least one of the first support and the second supports and configured to sense whether the first support rotates and switch the operation status of the charging socket when sensing the rotation of the first support.
