HEMP Protected Enclosure for Telecommunications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current HEMP protection systems for telecommunications equipment are costly and not well-suited for standard-sized storage facilities, failing to efficiently utilize space and meet spatial requirements.
Innovation Solution
Development of a HEMP protected telecommunications enclosure with a compact design that includes a cabinet and rack system, providing at least 80 dB attenuation at 1 GHz, and incorporating features like power and fiber optic cable entries, power filters, and battery trays, designed to meet MIL STD 188 125 1 standards while optimizing space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If custom protected rooms or oversized hardened enclosures are used for HEMP protection, then telecommunications equipment is protected from HEMP events, but floor space utilization is poor and spatial requirements are not met
Solution Approach 1:
The invention divides the protection system into modular rack enclosures that can be configured in standard telecommunications rooms. Instead of requiring a entire room to be hardened, the protection is segmented into individual rack units that fit within standard space constraints while providing HEMP protection through metallic shielding and filtered cable entries.
Solution Approach 2:
The rack enclosure is designed to be nested within standard telecommunications room infrastructure. The metallic enclosure fits within standard rack spaces, and cable management systems are nested within the enclosure structure, maximizing space utilization while maintaining protection.
2Reliability
If custom protected rooms are built for HEMP protection, then telecommunications equipment is protected, but cost increases significantly
Solution Approach 1:
The rack enclosure serves multiple functions: it provides HEMP protection through metallic shielding, organizes telecommunications equipment using standard rack mounting, manages cable entries with integrated filtering, and fits within standard telecommunications room infrastructure. This multi-functionality eliminates the need for separate custom-built protected rooms, reducing overall cost.
Solution Approach 2:
The invention uses commercially available metallic enclosures and off-the-shelf filtering components rather than custom-manufactured protection systems. By utilizing standard, readily available components, the cost of implementation is significantly reduced compared to custom-built protected rooms.
3Reliability
If oversized hardened enclosures are used, then HEMP protection is provided, but the enclosures do not meet spatial dimension requirements for standard telecommunications rooms
Solution Approach 1:
The rack enclosure is designed with adjustable and configurable elements that allow it to adapt to different spatial requirements within standard telecommunications rooms. Cable management systems can be configured based on available space, and the enclosure can be positioned to optimize use of vertical and horizontal space while maintaining protection.
