Engineering Contradiction Analysis
1Length of moving object
If copper-based data transmission methods are used, then data transmission is achieved, but the transmission range is limited due to signal damping
Solution Approach 1:
The patent introduces intermediary devices (repeaters/extension devices) that are inserted into the transmission line to actively regenerate and amplify the differential data signals. These intermediaries compensate for signal damping by boosting the signal amplitude, thereby extending the transmission range while maintaining signal quality. The intermediary devices include signal regeneration circuits that detect and retransmit the differential data signals with restored amplitude.
2Length of moving object
If line length is increased to extend transmission range, then coverage distance is improved, but signal amplitude decreases due to damping
Solution Approach 1:
The patent applies preliminary action by proactively boosting the signal amplitude at intermediate points along the transmission line before the signal degrades below usable levels. The extension devices are strategically placed to detect and amplify signals in advance, preventing excessive attenuation. This preliminary amplification ensures that the signal maintains sufficient amplitude throughout the extended line length.
Solution Approach 2:
The patent implements feedback mechanisms where the extension devices monitor the incoming differential data signals and adjust their amplification accordingly. The devices detect signal quality and amplitude, then regulate the regeneration process to maintain optimal signal levels. This feedback control ensures that signal amplitude is properly maintained across the extended transmission distance.
