Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If secure communication sessions are established to multiple distant locations, then remote access security is improved, but resource consumption and communication costs increase
Solution Approach 1:
The system performs preliminary actions by establishing a communication session between the remote access control apparatus and the communication relay apparatus before actual remote access is needed. This preliminary session allows the system to pre-configure secure communication paths, so when remote access is required, the connection can be quickly established without consuming additional resources for session setup. The command delivery section stores connection information obtained during this preliminary phase for later use.
Solution Approach 2:
The communication relay apparatus acts as an intermediary between the remote access control apparatus and the remote operation target device. This intermediary establishes a local communication session within the local network, allowing the remote access control apparatus to communicate securely without directly connecting to multiple distant locations simultaneously. The intermediary reduces resource consumption by consolidating communication through a single relay point rather than maintaining multiple direct connections.

3Ease of operation
If active connection is performed to obtain connection target information, then communication session establishment is improved, but system complexity increases
Solution Approach 1:
The communication relay apparatus performs self-service by actively connecting to the remote access control apparatus and transmitting connection target information automatically. This eliminates the need for the remote access control apparatus to implement complex active scanning or discovery mechanisms. The relay apparatus handles the complexity of establishing communication and providing connection information, simplifying the overall system architecture while improving ease of operation.

AI summary
[PROBLEM] To provide a remote access control system for controlling remote access to each of connection targets located at distant places. [SOLVING MEANS] A remote access control system according to embodiments includes a remote access control apparatus and a communication relay apparatus. The remote access control apparatus is configured to establish a predetermined communication session with the communication relay apparatus through predetermined connection target information obtaining processing performed by active connection to the remote access control apparatus from the communication relay apparatus, to transmit a secure communication connection start command to the communication relay apparatus, to receive a secure communication connection request from the communication relay apparatus to perform processing for establishing a first secure communication session, and to receive a secure communication connection request from the user apparatus based on the result of the establishment of the first secure communication session to perform processing for establishing a second secure communication session. The connection between the individually established secure communication sessions is determined based on session connection permission information to relay the secure communication sessions.
