Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is challenging to reduce the overall thickness of electronic devices equipped with receptacles for connecting external devices while maintaining effective ground shielding and electromagnetic interference (EMI) protection.
Innovation Solution
A receptacle design featuring a rotatable door cover and multiple metal members that allows for grounding and EMI shielding, with a structure that facilitates easy automatic optical inspection and manual soldering, enabling high-speed data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a receptacle is mounted in the housing to enable external device connection, then electrical connection capability is improved, but housing thickness increases
Solution Approach 1:
The door cover is designed to be rotatable rather than fixed, allowing it to move between open and closed positions. This dynamic structure enables the receptacle to be accessed when needed while maintaining a slim profile when closed, resolving the contradiction between connection capability and thickness.
Solution Approach 2:
The receptacle assembly is nested within the housing structure with the door cover forming part of the integrated assembly. The rotatable door cover nests over the receptacle when closed, allowing the connection mechanism to be compact while still providing full functionality when accessed.
2Object-affected harmful factors
If metal members are added for grounding and EMI shielding, then electromagnetic protection is improved, but device complexity increases
Solution Approach 1:
The grounding and EMI shielding functions are merged into the existing door cover and receptacle structure through metal members that are integrated with these components. This combines multiple functions (structural support, grounding, EMI shielding) into a unified design, improving protection without proportionally increasing complexity.
Solution Approach 2:
The metal members serve multiple functions simultaneously: they provide structural support for the door cover, establish grounding connections, and offer EMI shielding. This multi-functionality approach addresses the EMI protection need while minimizing the increase in device complexity.

AI summary
An electronic device includes a housing which defines an external device connector hole, and a receptacle connected to the housing at the external device connector hole and openable and closeable. The receptacle includes a first metal member including an electrical connection part exposed to outside the first metal member in a direction away from the external device connector hole, and a door cover which faces the first metal member, is rotatably coupled to the housing at the external device connector hole, and rotatable relative to the first metal member. The receptacle which is open includes the door cover rotated away from the first metal member and the connection part connectable to an external device plug, and the receptacle which is closed includes the door cover rotated toward the first metal member and the connection part unconnectable to the external device plug.
