Movable Shielding Member for Electronic Housing EMI Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic systems face challenges in protecting against unexpected electromagnetic waves generated during usage, as standard shielding members cannot be effectively designed to mitigate these specific and environment-dependent radiated noises, leading to operation failures in devices like SSD server systems.
Innovation Solution
A housing with an embedded electromagnetic shielding member that contacts a grounding line, creating a shielding space within the electronic system, which automatically shields devices from unexpected electromagnetic waves without additional shielding processes, and includes recesses for improved space efficiency and heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard electromagnetic shielding members are provided with electronic devices during manufacturing, then expected electromagnetic waves can be blocked, but unexpected electromagnetic waves generated during usage cannot be effectively shielded
Solution Approach 1:
The housing includes a movable shielding member that can change position between a first position (when electronic device is not inserted) and a second position (when electronic device is inserted). This dynamic adjustment allows the shielding structure to adapt to different usage states and effectively block unexpected electromagnetic waves generated during operation, while maintaining standard shielding capabilities for expected waves.
Solution Approach 2:
The shielding member is pre-configured in the housing to automatically move to the appropriate position when an electronic device is inserted. This preliminary positioning ensures that shielding protection is activated in advance before unexpected electromagnetic waves are generated during device operation, providing proactive protection rather than reactive shielding.
2Reliability
If shielding members are added to protect against unexpected electromagnetic waves, then device protection improves, but device complexity and manufacturing processes increase
Solution Approach 1:
The housing structure integrates multiple functions: it serves as both the device enclosure and the mounting structure for the movable shielding member. The housing itself provides structural support while the integrated shielding member provides electromagnetic protection, eliminating the need for separate complex shielding assemblies and reducing overall device complexity.
Solution Approach 2:
The shielding function is merged with the housing structure by making the shielding member a movable component within the housing. This combination integrates the shielding mechanism into the existing housing design, avoiding additional complex structures and simplifying manufacturing processes while maintaining effective protection against unexpected electromagnetic waves.
3Object-affected harmful factors
If shield cans are provided for each component, then electromagnetic interference between components is reduced, but space efficiency and heat dissipation are compromised
Solution Approach 1:
The housing is divided into a first housing portion and a second housing portion, with the movable shielding member positioned between them. This segmentation creates distinct electromagnetic zones that prevent interference between components in different portions, while the movable nature of the shielding member allows it to adapt to the actual space requirements, maintaining space efficiency.
4Reliability
If additional shielding processes are applied to the system board, then electromagnetic protection improves, but manufacturing time and cost increase
Solution Approach 1:
The shielding member is pre-configured in the housing during housing manufacturing, before the electronic device assembly is completed. When the electronic device is inserted into the housing, the shielding member automatically moves to its protective position, providing electromagnetic protection without requiring additional shielding processes to be applied to the system board during device assembly, thus reducing manufacturing time.

Implementation Method 1
an electromagnetic shielding member embedded onto an inner surface of the case such that the electromagnetic shielding member may be contact with the grounding line to thereby provide a shielding space defined by the board and the electromagnetic shielding member. The shielding space may be shielded from electromagnetic waves by the electromagnetic shielding member.
