Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current videoconference systems require duplicate equipment for secure and non-secure networks, leading to increased costs and inefficiencies, and existing solutions like patch bays are prone to errors and physical wear.
Innovation Solution
A switching unit utilizing an electromechanical relay network to connect audio/visual components and a single codec to multiple networks with different security levels, ensuring isolation and secure communication by using DC actuated relays to control connections and prevent simultaneous energization of control signals for secure and non-secure networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If duplicate videoconferencing equipment is provided for secure and non-secure networks, then network security isolation is improved, but system cost and complexity increase
Solution Approach 1:
The patent combines secure and non-secure network connections through a single videoconferencing system by using a switching unit that can dynamically connect the codec to different networks. This eliminates the need for duplicate equipment while maintaining security isolation through controlled switching rather than physical separation.
Solution Approach 2:
The switching unit dynamically reconfigures network connections based on security requirements. The system can transition between secure and non-secure networks in real-time, allowing a single piece of equipment to adapt to different security contexts without requiring permanent duplicate setups.
2Device complexity
If a patch bay is used to switch connections between networks, then equipment duplication is reduced, but reliability decreases due to physical wear and configuration errors
Solution Approach 1:
The patent replaces the mechanical patch bay system with an electronic switching unit that uses electrical relays or switches to connect the codec to different networks. This eliminates physical connector wear and configuration errors while maintaining the ability to switch between secure and non-secure networks.
3Adaptability or versatility
If manual switching is used in a patch bay system, then flexibility is improved, but error risk increases due to human configuration mistakes
Solution Approach 1:
The switching unit automatically manages network connections based on programmed logic or control signals, eliminating manual configuration by operators. The system self-configures network switches based on security requirements, reducing human error while maintaining flexibility in network selection.
