Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing charging socket systems require disassembly of the entire unit for replacing a faulty charging terminal, leading to inefficient and time-consuming repair processes due to the welding mode of connection between the terminal and cable, which complicates the repair and replacement of damaged components.
Innovation Solution
A charging socket design featuring a detachable charging adapter with a connection structure that allows for sequential removal and replacement of the charging terminal without disassembling the entire socket, using a detachable structure and connection mechanism that includes various welding modes such as crimping, resistance welding, and ultrasonic welding, allowing for easier maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a welding mode is adopted for the charging terminal and the cable, then the connection is strong and reliable, but the repair process becomes complex and time-consuming
Solution Approach 1:
The charging terminal is divided into separate modular components: the charging terminal body, the cable connection interface, and the adapter. This segmentation allows the charging terminal to be detached and replaced without affecting the cable or other components, enabling quick repairs while maintaining reliable connections through standardized interfaces.
Solution Approach 2:
The charging terminal is designed with dynamic detachability, allowing it to be easily connected and disconnected from the cable and adapter. This dynamic design replaces the static welded connection with a reusable mechanical-electrical interface that maintains reliability while enabling rapid replacement and repair.
2Stability of the object's composition
If the charging terminal is fixed on the charging socket body, then the structure is stable, but the entire socket must be disassembled for terminal replacement
Solution Approach 1:
The charging terminal is segmented from the charging socket body through the adapter interface. This allows the terminal to be independently removed and replaced without disassembling the entire socket assembly, reducing repair time while maintaining stable structural connections through the adapter mounting mechanism.
Solution Approach 2:
The charging terminal is extracted as a separate replaceable component from the charging socket body. The adapter serves as the mounting interface that can be quickly detached, allowing the terminal to be taken out and replaced without affecting the main socket structure, thus reducing replacement time while preserving structural stability.
3Reliability
If the cable is connected with the charging terminal via welding, then the electrical connection is reliable, but the cable must be replaced when the terminal is damaged
Solution Approach 1:
The electrical connection system is segmented into the cable, adapter, and charging terminal as separate components. The adapter provides a reusable electrical interface between the cable and terminal, eliminating the need to replace the entire cable assembly when the terminal is damaged, thus improving maintenance efficiency while maintaining reliable electrical connections.
Solution Approach 2:
The adapter serves as an intermediary component between the cable and charging terminal. It provides a reusable electrical connection interface that allows the terminal to be replaced without affecting the cable, eliminating the need to replace the entire cable assembly and significantly improving maintenance efficiency while ensuring reliable electrical connections.
4Ease of repair
If outer sheath and tapes of the entire cable are removed for repair, then the damaged terminal can be accessed, but the repair process consumes a lot of manpower and time
Solution Approach 1:
The charging terminal assembly is segmented from the cable through the adapter interface. This allows the terminal to be accessed and replaced by simply detaching the adapter, eliminating the need to remove cable protective layers and significantly reducing the manpower and time required for repairs.
Solution Approach 2:
The adapter is pre-mounted on the charging terminal during manufacturing, creating a ready-to-detach interface. This preliminary action ensures that during repair, the terminal can be quickly accessed by simply removing the adapter without needing to perform time-consuming cable disassembly operations, thus improving repair efficiency.

AI summary
The present disclosure provides a charging socket and an vehicle, including: a charging socket body, a charging terminal, a charging adapter and a cable, in which the charging adapter includes a detachable structure and a fixed end which are connected in sequence, the fixed end is electrically connected with a conductor of the cable, the charging adapter is fixedly mounted on the charging socket body, a connection structure is provided on the charging terminal, and the charging terminal is detachably connected with the detachable structure via the connection structure. The charging adapter is capable of detachably connecting the charging terminal with the charging socket body and electrically connecting with the cable. In this way, when a relevant connecting element inside the charging socket is damaged, the charging terminal and the charging adapter may be removed in sequence, and a faulty charging terminal is replaced without removing the entire charging socket and replacing the cable, which greatly reduces the work intensity and saves the repair time.
