Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If analog data conversion is used for IP network fax transmission, then compatibility with traditional fax modems is maintained, but transmission speed is restricted and time required for transmission/reception increases
Solution Approach 1:
The invention extracts and eliminates the analog data conversion step from the transmission path. By directly transmitting digital data over IP networks without converting to analog format, the system removes the speed bottleneck associated with analog modulation, thereby achieving faster transmission while maintaining compatibility through protocol adaptation.
Solution Approach 2:
The invention changes the data format parameter from analog to digital for IP network transmission. This parameter change enables the system to bypass the speed limitations of analog fax modems and utilize the higher bandwidth capabilities of digital IP networks, directly addressing the transmission speed and time requirements.
2Productivity
If sequential transmission to multiple destinations is performed using analog data, then traditional fax protocols are followed, but transmission time to all destinations increases significantly
Solution Approach 1:
The invention segments the transmission process into parallel digital data streams for multiple destinations. Instead of sequentially transmitting to one destination at a time, the system divides the image data into separate digital transmission channels that can be sent simultaneously over the IP network, dramatically improving productivity and reducing total transmission time.
Solution Approach 2:
The invention performs preliminary digital data preparation and packetization before transmission, enabling the data to be ready for simultaneous parallel transmission to multiple destinations. This preliminary action includes formatting the digital data according to different communication protocols (real-time vs. deemed voice), allowing the system to efficiently manage multiple transmission streams without sequential delays.
3Speed
If digital data is transmitted directly without analog conversion, then transmission speed increases, but compatibility with destinations requiring analog processing may be affected
Solution Approach 1:
The invention implements a universal transmission system that can handle both real-time communication methods (T.38) and deemed voice communication methods (G.711) over IP networks. The system maintains adaptability by providing multiple digital data generation paths that can be selected based on the destination's capabilities, ensuring broad compatibility while maintaining high-speed digital transmission throughout the system.
