Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple driving devices are used to control multiple lock rods for different charging interfaces, then each charging interface can be independently controlled, but the number of parts increases and manufacturing cost increases
Solution Approach 1:
A single driving device is designed to perform multiple functions by controlling both the first lock rod (for DC charging interface) and the second lock rod (for AC charging interface) through shared transmission mechanisms, eliminating the need for separate driving devices for each charging interface
Solution Approach 2:
The driving device is merged with transmission mechanisms that are shared between the first and second lock rods, combining multiple control functions into a unified system that reduces the total number of components while maintaining independent control capability for different charging interfaces
2Reliability
If multiple driving devices are used to control multiple lock rods, then each charging gun can be locked independently, but manufacturing cost increases
Solution Approach 1:
The single driving device is designed with multi-functionality to control both DC and AC charging gun locking operations, reducing manufacturing cost by eliminating redundant components while maintaining reliable independent control for each charging interface through shared transmission mechanisms

AI summary
An electronic lock, an electric automobile charging socket, and a motor vehicle, including: a driving device configured to generate a rotational movement; a first lock rod connected to the driving device through a first transmission mechanism, the first transmission mechanism being configured to convert the rotational movement of the driving device into a movement of the first lock rod; and a second lock rod connected to the driving device through a second transmission mechanism, the second transmission mechanism being configured to convert the rotational movement of the driving device into a movement of the second lock rod. According to the embodiments of the present disclosure, since two transmission mechanisms are disposed to be connected to the driving device, only one driving device needs to be provided to drive the two lock rods to move simultaneously, which enables the electronic lock to lock both a DC charging gun and an AC charging gun without increasing the manufacturing cost of the electronic lock; and the electronic lock has a simple structure and is convenient to use.
