Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the socket continuously outputs power in standby mode, then the socket is ready to supply power immediately, but unnecessary energy is consumed and wear increases
Solution Approach 1:
The detection electrode assembly is pre-positioned to detect plug insertion before power is supplied. The control circuit is pre-configured to monitor the detection electrode and automatically activate power supply when needed, eliminating the need for continuous power output while maintaining readiness.
Solution Approach 2:
The detection electrode assembly provides real-time feedback about plug insertion status to the control circuit. This feedback mechanism allows the socket to dynamically adjust power supply based on actual usage conditions, stopping power output when no plug is detected and reducing standby energy consumption.
2Speed
If power is supplied immediately upon plug contact, then power availability is ensured, but high current surge causes sparking and safety hazards
Solution Approach 1:
The detection electrode assembly is positioned to detect plug insertion before the plug contacts the power supply electrodes. This preliminary detection allows the control circuit to prepare for power supply in advance, enabling smooth power transition without sudden current surges or sparking when the plug makes contact.

AI summary
A socket assembly and an electronic apparatus are disclosed. The socket assembly comprises a socket body, a power supply electrode group, and a detection electrode assembly. The power supply electrode group is configured to contact a plug electrode group inserted into the socket body, and contacting the plug electrode group when the plug electrode group is further inserted to a preset position in the socket body. The detection electrode assembly is configured to detect the insertion state of the plug electrode group. When the plug electrode group is not inserted to the preset position, the detection electrode assembly is in the off state. When the plug electrode group is inserted to the preset position, the detection electrode assembly is in the on state to form a current loop. The socket assembly can effectively improve the use safety of a socket and effectively save energy.
