EMC Scattering Cape for Rack-Mounted Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer systems and equipment often fail to meet electromagnetic compatibility (EMC) standards due to the absence of metal doors on racks, leading to electromagnetic interference and potential safety hazards.
Innovation Solution
The development of an EMC scattering cape apparatus that attaches to computer systems and equipment, featuring a conductive fabric cape that flutters in response to airflow to scatter electromagnetic energy, thereby providing immunity and ensuring compliance with EMC standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal doors are installed on racks to provide electromagnetic shielding, then EMC compliance is improved, but device complexity and cost increase
Solution Approach 1:
The EMC shielding function is segmented from the rack structure itself and implemented as a separate, removable scattering apparatus that can be attached to specific equipment requiring protection, rather than requiring entire rack doors
Solution Approach 2:
EMC protection is applied locally to specific equipment or components that require it, rather than providing universal shielding across the entire rack structure, reducing overall complexity and cost
2Object-generated harmful factors
If metal doors are installed on racks to scatter electromagnetic energy, then radiated emissions are reduced, but manufacturing cost and installation complexity increase
Solution Approach 1:
The scattering apparatus uses inexpensive conductive fabric or mesh material that can be easily manufactured and replaced if needed, avoiding the cost of metal door assemblies
Solution Approach 2:
The scattering apparatus incorporates movable or flexible elements that can adapt to different equipment configurations, providing effective shielding without requiring precise, complex manufacturing tolerances
3Object-affected harmful factors
If conventional EMC shielding structures are used, then electromagnetic interference is blocked, but airflow required for cooling is obstructed
Solution Approach 1:
The scattering apparatus uses thin, flexible conductive fabric or mesh that allows airflow to pass through while maintaining electromagnetic scattering functionality, unlike solid metal doors that completely block airflow
Solution Approach 2:
The conductive fabric acts as an intermediary between the equipment and the surrounding environment, providing EMC protection while allowing cooling airflow to continue unobstructed

AI summary
An electromagnetic compatibility (EMC) scattering apparatus comprising an attachment component, a scattering cape, and a brace. The attachment component is configured to permit the EMC scattering apparatus to attach to a second object such as a drawer, cable outlet, cable connector, etc. The scattering cape is attached to the attachment component and is configured to scatter energy emitted from the second object by fluttering in response to airflow from the second object. The brace is connected to the attachment component, the brace is configured to keep the scattering cape in an extended position. The brace can also be attached to the scattering cape.
