Solution Overview
Problem
Existing communication systems for high-security facilities face challenges in securely connecting devices while preventing unauthorized access, especially when devices are physically apart, making it difficult to maintain security and operability.
Innovation Solution
A communication connection apparatus that controls the connection of communication lines between devices, featuring a first and second connection port, a switching unit, and a simulated-signal input unit to establish a secure communication state, allowing data output from a protection-target device while preventing physical access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices are physically connected via dedicated line to improve security, then security is improved, but installation becomes troublesome when devices are apart
Solution Approach 1:
The patent introduces a communication connection apparatus as an intermediary device that physically connects to the protection-target communication device and simulates another communication device. This intermediary apparatus enables secure data output while maintaining physical disconnection between the protection-target device and external networks, thus improving installation ease without compromising security.
2Productivity
If devices are physically connected to communication line for data transmission, then data transmission is enabled, but protection-target device becomes accessible creating security risk
Solution Approach 1:
The patent segments the communication system into distinct functional parts: a communication connection apparatus that handles physical connections and a protection-target communication device that remains physically isolated. This segmentation allows data transmission functionality to be separated from the protection-target device, enabling data output while preventing unauthorized access to the protected device.
Solution Approach 2:
The communication connection apparatus serves as an intermediary that physically connects to the protection-target device's transmission unit but presents a simulated reception unit to external networks. This intermediary structure enables data transmission from the protection-target device to external systems while maintaining physical disconnection at the reception unit, thus preventing unauthorized access.
3Productivity
If simulated signal is input to reception unit while physically disconnected, then data output is enabled, but connection state becomes complex
Solution Approach 1:
The patent extracts the reception unit function from the protection-target communication device and places it in the communication connection apparatus. The reception unit is physically disconnected from the protection-target device, allowing data output through simulated signals while simplifying the connection state management by centralizing the physical connection interface in the intermediary apparatus rather than in the protected device itself.

AI summary
A communication connection apparatus controls connection of a communication line between a first and second communication devices comprising: a first connection port for the first communication device, including a first transmission unit through which a signal from the first communication device passes and a first reception unit through which a signal for the first communication device passes; a second connection port for the second communication device, including a second transmission unit through which a signal from the second communication device passes and a second reception unit through which a signal for the second communication device passes; a first connection line connecting the first transmission unit and the second reception unit; and a simulated-signal input unit that inputs a first signal to the first reception unit. On the first signal being input to the first reception unit, the first reception unit and the second transmission unit are physically disconnected.
