Hinged Shielding Cover Structure for Easy Module Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shielding devices for electronic modules, such as DDR5 memory, are inconvenient to disassemble as they require removal of the housing baseboard, leading to potential user errors in closing the shielding cover, which affects the shielding effectiveness.
Innovation Solution
A shielding device with a fixing frame and a pivotally connected shielding cover that can be easily opened and closed without dismantling the housing baseboard, ensuring convenient access and reassembly of electronic modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the shielding cover is integrated with the housing baseboard, then the shielding effect is improved, but the ease of operation deteriorates
Solution Approach 1:
The shielding device is divided into two separate components: a fixed baseboard that provides structural support and shielding, and a movable shielding cover that can be opened and closed. This segmentation allows the shielding function to be maintained while enabling easy access to the electronic module without dismantling the entire housing structure.
Solution Approach 2:
The shielding cover is designed with movable connections (hinges or slides) that allow it to dynamically change position between closed (shielding) and open (access) states. This dynamic design enables the shielding structure to adapt between providing protection and allowing maintenance access, resolving the contradiction between fixed shielding and easy operation.
2Ease of operation
If the shielding cover is made detachable, then the ease of operation is improved, but the reliability deteriorates
Solution Approach 1:
The shielding cover employs dynamic connection mechanisms (hinges or slides with guides) that maintain a secure, continuous connection between the cover and baseboard during operation. This ensures the shielding integrity is preserved while still allowing controlled opening and closing for maintenance access.
Solution Approach 2:
Guide grooves and guide rods act as intermediary elements between the shielding cover and baseboard, ensuring precise alignment and stable connection during opening and closing operations. These intermediaries maintain the shielding effectiveness by preventing gaps or misalignment while enabling smooth movable operation.
3Ease of operation
If guide grooves and guide rods are added, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The guiding function is segmented into separate components (guide grooves in the baseboard and guide rods on the cover) rather than attempting to integrate guidance into the main connection structure. This segmentation simplifies the overall design by dedicating specific elements to specific functions while maintaining ease of operation.
Solution Approach 2:
The guide grooves and guide rods serve multiple functions: they provide mechanical guidance for smooth opening/closing, maintain alignment between the cover and baseboard, and ensure proper positioning during both open and closed states. This multi-functionality justifies the added structural elements by consolidating multiple requirements into unified components.

AI summary
A shielding device is suitable for applying in an electronic module arranged on a mainboard of an electronic device having a housing baseboard. The mainboard is provided with a connector. The shielding device includes a fixing frame and a shielding cover. The fixing frame is provided with an accommodating space suitable for accommodating the connector and the electronic module. The fixing frame includes two first side walls, two second side walls, and a press plate connecting to one of the two first side walls and covering the connector. A part of the press plate is covered by the housing baseboard. The shielding cover is pivotally connected to one side, away from the press plate, of the fixing frame and may be opened or closed relative to the fixing frame. The electronic module is exposed through opening of the shielding cover and is shielded through closing of the shielding cover.
