Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a virtual circuit connection is established for data transmission over the telephone network, then reliable communication between data communications devices is achieved, but telecommunications resources are wasted due to dedicated bandwidth allocation for sporadic transmissions
Solution Approach 1:
The patent segments the data transmission process by separating the control/connection establishment phase from the actual data payload transmission. The virtual circuit is established only when needed, and data is transmitted in discrete packets rather than requiring continuous dedicated bandwidth. This allows the system to maintain reliable communication when active while minimizing resource allocation during idle periods.
Solution Approach 2:
The patent implements dynamic resource allocation where the virtual circuit connection is established temporarily only when data transmission is required, rather than maintaining a static dedicated connection. The connection is set up on-demand and torn down when not in use, allowing telecommunications resources to be dynamically reassigned to other uses during idle periods, thus reducing resource waste while maintaining communication reliability.
2Reliability
If dedicated bandwidth is allocated for virtual circuit connections, then data transmission reliability is ensured, but bandwidth utilization efficiency decreases due to sporadic transmission patterns
Solution Approach 1:
The patent employs periodic action by establishing virtual circuit connections only during periods when data transmission is actually needed, rather than maintaining continuous dedicated bandwidth allocation. The system activates the virtual circuit temporarily for data packets and deactivates it during idle periods, allowing other traffic to utilize the bandwidth. This periodic activation pattern ensures reliable transmission when active while significantly improving overall bandwidth utilization efficiency.
3Length of moving object
If modem pools are deployed close to telecommunications switches, then the distance between data networks and users is reduced, but device complexity and infrastructure cost increase
Solution Approach 1:
The patent makes the telecommunications switch itself multi-functional by enabling it to directly terminate data communications equipment and perform data packetization, demodulation, and data network interfacing functions. Instead of requiring separate modem pools as dedicated data network infrastructure, the switch can handle both traditional voice telephony and data communications universally. This eliminates the need for additional modem pool hardware, reducing infrastructure complexity while maintaining short distance connections.
Solution Approach 2:
The patent merges the functions of the telecommunications switch and the modem pool into a single integrated system. The switch is enhanced to directly terminate data communications equipment, demodulate signals, packetize data, and interface with data networks. This consolidation eliminates the need for separate modem pool infrastructure, reducing overall system complexity and infrastructure costs while achieving the goal of short distance connections between users and data networks.

AI summary
When receiving a telephone call, a telecommunications switch (150) analyzes the telephone call to determine if the telephone call includes a data transmission that complies with a predetermined data protocol. If the telephone call includes a data transmission that complies with a predetermined data protocol then a demodulator (212) demodulates the digital information signal contained in the data transmission. A data network interface (216) packetizes the digital information signal into a packet for transmission into a data network (118). Similarly, the data network interface (216) receives packets from a data network (118). The packets are converted into a data transmission for transfer over a telephone call to a device terminated by the telecommunications switch (150).
