Dust-Proof Mechanism for Memory Module with Removable Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dust-proof mechanisms for memory modules in telecommunication systems restrict airflow and require the entire PCB to be replaced if the memory is damaged, limiting memory replacement and PCB design flexibility.
Innovation Solution
A dust-proof telecommunication system with a chassis having an opening for easy access and replacement of memory modules, where the memory module is enclosed by sheets and a clip, allowing airflow through the sides and enabling easy installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the memory is directly welded to the PCB for dust-proofing, then the dust-proof performance is improved, but the ease of repair deteriorates because the entire PCB must be replaced when memory is damaged
Solution Approach 1:
The memory module is segmented from the PCB through the use of a removable cover structure. The memory chip remains mounted on the PCB, but the cover that encloses the memory can be independently removed and replaced, allowing the memory assembly to be serviced without replacing the entire PCB while maintaining dust-proof enclosure when assembled.
2Reliability
If the entire PCB is covered with die casting for dust-proofing, then the dust-proof performance is improved, but the device complexity increases and limits the number of memory modules that can be supported
Solution Approach 1:
Instead of using a single die-cast cover for the entire PCB, the invention segments the protection into individual removable covers for each memory module. This reduces overall device complexity, improves PCB design flexibility, and allows multiple memory modules to be supported while maintaining dust-proof performance for each module.
Solution Approach 2:
The invention transitions from a two-dimensional PCB surface mounting approach to a three-dimensional modular assembly with removable covers. This dimensional change allows memory modules to be accessed and replaced from the top side through openings in the cover, eliminating the need for complex PCB routing and enabling greater design flexibility.
3Reliability
If the PCB is completely covered by die casting, then the dust-proof performance is improved, but the heat dissipation efficiency deteriorates due to restricted airflow
Solution Approach 1:
The cover is designed with localized openings at specific positions to allow airflow for heat dissipation while maintaining dust-proof protection in other areas. This local modification optimizes both heat dissipation efficiency and dust-proof performance by providing targeted ventilation paths without compromising the overall enclosure integrity.

AI summary
A dust-proof telecommunication system and a method for assembling a dust-proof mechanism are disclosed. The system includes a chassis including an opening on a top side thereof; a PCB located within the chassis; a memory module removably installed on the PCB; and a cover removably coupled to the top side of the chassis. The opening is positioned and shaped such that the memory module is accessible via the opening for easy replacement. The method includes inserting a strip into the opening such that a space is formed between a wall of the opening and the strip; and inserting the memory module into the space formed between the wall of the opening and the strip such that another strip located at a first side of the memory module contacts the wall and the strip contacts a second side of the memory module. The memory module is replaceably coupled to the PCB.
