Removable-Lid Network Isolation Box for Fast Secure Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current networked communication systems face challenges in quickly isolating or disconnecting networked devices, especially in avionic computers, due to the need for physical removal and reinstallation during maintenance, which is time-consuming and costly, particularly when access is required in flight or in sealed environments.
Innovation Solution
A network switch box with a jumper circuit board and removable lid that allows remote verification of connection status, enabling quick connection or disconnection of networked devices without physical removal, and exposing maintenance ports when the lid is removed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical removal and reinstallation of computer hardware is performed for maintenance or network isolation, then network security and isolation are ensured, but time consumption and operational disruption increase significantly
Solution Approach 1:
The invention segments the isolation function from the hardware itself by introducing a separate network isolation device (NID) that acts as an intermediary between the computer and the network. This allows the computer to remain physically installed while the NID handles the isolation function, eliminating the need to physically remove hardware for network security purposes.
Solution Approach 2:
The network isolation device serves as an intermediary component between the computer hardware and the network infrastructure. It provides the necessary isolation and security functions without requiring physical removal of the computer, thus maintaining both security and operational continuity.
2Reliability
If computer hardware is removed from the rack for network disconnection, then complete network isolation is achieved, but access to maintenance ports and physical reinstallation become cumbersome
Solution Approach 1:
The invention extracts the network isolation function from the computer hardware itself and places it in a separate, dedicated device. This extraction allows the computer to remain installed in the rack while the isolation function is provided by the NID, making maintenance ports accessible without removing the computer.
Solution Approach 2:
The solution moves the isolation function from the physical dimension (requiring hardware removal) to a logical/dimensional layer where the NID manages network connectivity independently. This allows maintenance access while maintaining network isolation through the NID's control mechanisms.
3Reliability
If approved access procedures are followed for removing computer hardware from sealed environments, then environmental security is maintained, but operational efficiency and cost increase due to multiple approval and inspection steps
Solution Approach 1:
The network isolation device provides self-service isolation capabilities that do not require external approval processes. The NID can independently manage network connectivity and isolation, eliminating the need for multiple approval and inspection steps while maintaining environmental security through its designed containment features.
4Manufacturing precision
If specialized tools are used to remove and reinstall computer hardware, then proper handling and installation are ensured, but equipment cost and complexity increase
Solution Approach 1:
The invention merges the isolation function with the network connection interface itself by making the NID an integral part of the network cabling infrastructure. This integration eliminates the need for separate specialized tools, as the NID handles both the isolation function and the connection interface in a single unified component.

AI summary
Provided is a secure quick communication system disconnect switch box that enables remote verification of communication path connection or disconnection status. The box utilizes a lid having an affixed jumper circuit/assembly bridging or coupling at least two network connections. When the lid to the switch box is attached, the at least two computers/networks are connected via the jumper circuit/assembly. When the lid is removed from the switch box, the jumper circuit/assembly is disconnected from the at least two computer/networks, thereby disconnecting and isolating the otherwise coupled computers/networks. Removal of the lid additionally exposes network maintenance/access ports to provide access to one or more of the computers/network. When the lid is closed, the network maintenance/access ports are inaccessible to the user.
