Innovation Solution
The remote device incorporates a downlink and uplink path control unit with bypass lines and switches to connect remote driving units in series, allowing RF signals to bypass any unit for maintenance and enabling easy replacement, thus preventing signal damage and simplifying wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If remote driving units are arranged in parallel to process multiple frequency bands, then the device can handle multiple frequency bands simultaneously, but the original signals are damaged due to division and combination by one divider
Solution Approach 1:
The patent divides the remote device into multiple independent remote driving units, each dedicated to a specific frequency band. Each unit has its own complete signal path from optical conversion unit to antenna, avoiding signal division and combination. This segmentation maintains signal integrity while enabling multi-frequency band operation through parallel independent units.
2Adaptability or versatility
If remote driving units are arranged in parallel with one divider, then multiple frequency bands are processed, but wiring design becomes difficult and connection errors increase
Solution Approach 1:
By segmenting the device into independent remote driving units, each unit has its own dedicated wiring path. This eliminates the complex wiring design required for parallel units sharing a common divider, as each unit's wiring is self-contained and straightforward, connecting only its specific frequency band components.
3Adaptability or versatility
If remote driving units are arranged in parallel, then multiple frequency bands are supported, but assembly and replacement of units becomes difficult
Solution Approach 1:
The patent implements modular remote driving units that can be independently assembled and replaced. Each unit is a self-contained module handling a specific frequency band, making assembly straightforward through modular integration and replacement simple by swapping individual units without affecting other frequency bands.
4Ease of repair
If remote driving units are arranged in series with path control, then units can be easily replaced with bypass capability, but the device structure becomes more complex
Solution Approach 1:
The patent introduces path control units as intermediary components that manage signal routing between the optical conversion unit and remote driving units. These intermediaries provide bypass capabilities and replacement functionality through controlled switching, isolating the complexity of path management from the remote driving units themselves while enabling easy replacement and maintenance.

Function Achieved in This Case
This configuration ensures reliable signal transmission by preventing original signal damage, reducing connection errors, and facilitating easy assembly and replacement of remote driving units, maintaining normal operation even when units are removed or changed.
Implementation Method 1
The optical conversion unit serves to convert a downlink RF signal received from a base station to an optical signal thereby transmitting to a remote device, and to convert an uplink RF signal received from the remote device to the RF signal thereby transmitting to the base station

AI summary
A remote device of an optical relay system includes first and second remote driving units each extracting transmission signals of different frequency bands from downlink Radio Frequency (RF) signals provided from an optical conversion unit and outputting the transmission signals; and a downlink path control unit receiving the downlink RF signals from the optical conversion unit and transmitting the downlink RF signals to the second remote driving unit through the first remote driving unit, or transmitting the downlink RF signals to the second remote driving unit by bypassing the first remote driving unit.
