Shielding Device Segmented Case Sliding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shielding devices for electronic components are cumbersome and difficult to maintain due to their size and weight, often requiring central attachment and cutting of components for access, which can be time-consuming and risk damage.
Innovation Solution
A shielding device comprising a first case and a second case with sliding mechanisms and limiting structures that allow for easy assembly and disassembly, reducing the overall height and enabling balanced stress distribution, facilitating maintenance without the need for central attachment or cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a protruding engaging structure is used to fix the first case and second case, then the shielding device achieves stable connection, but the height increases to at least 1.5 mm and assembly becomes difficult
Solution Approach 1:
The engaging structure is divided into a protruding portion on one case and a corresponding slot on the other case, allowing separate formation and easier assembly while maintaining stable connection
Solution Approach 2:
The slot acts as an intermediary element that receives the protruding portion, enabling smooth engagement without requiring complex protruding structures that increase height
2Area of stationary object
If the second case is made large to accommodate electronic components, then the shielding coverage is improved, but the device becomes heavy and may slant or lean during installation
Solution Approach 1:
The shielding device is divided into a first case and second case that can be separately assembled, allowing the shielding coverage to be achieved without requiring a single large heavy case
Solution Approach 2:
The engaging structure uses horizontal protruding portions and slots rather than vertical height, allowing stable connection without increasing device height, thus preventing slanting during installation
3Stability of the object's composition
If a cross bar is disposed at the center for assembling equipment, then the shielding device achieves balanced attachment, but maintenance requires cutting the cross bar which is time-consuming and may damage electronic components
Solution Approach 1:
The case is divided into separable first and second cases with engaging structures, allowing the first case to be removed for maintenance without cutting, thus improving accessibility while maintaining attachment balance through the engaging structure design
Solution Approach 2:
The engaging structure allows dynamic assembly and disassembly through the protruding portion and slot mechanism, enabling easy removal of the first case for maintenance while maintaining stable attachment during operation
4Length of stationary object
If the height of the first case is reduced below 1.5 mm, then the overall device size is minimized, but surface mount technology may cause permanent fixation making assembly difficult
Solution Approach 1:
The case is segmented into first and second cases with horizontal engaging structures (protruding portions and slots) that enable assembly and disassembly at reduced heights without permanent fixation
Solution Approach 2:
The engaging structure provides dynamic assembly capability through the protruding portion fitting into the slot, allowing easy assembly and disassembly even when case height is reduced below 1.5 mm, preventing permanent fixation

AI summary
A shielding device and an electronic device having the same are disclosed. The shielding device is disposed on a circuit board for covering an electronic component. The shielding device comprises a first case and a second case. The first case comprises a first limiting structure and a second limiting structure. The second case is mounted on the circuit board and includes a frame and a first slot. The frame forms an opening. When the first case is connected with the second case, the second limiting structure can move along a first direction to a bottom of the frame and is prevented from moving along a second direction. The first slot corresponds to the first limiting structure to allow the first limiting structure to be inserted into the first slot along the first direction and the first limiting structure is prevented from moving along the second direction.
