Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing signal coupling devices face challenges in efficiently transmitting both time-duplex and frequency-duplex signals in the same frequency ranges, leading to increased energy consumption, unnecessary amplification, and higher costs due to the need for duplex filters, which also attenuate time-duplex signals.
Innovation Solution
A signal coupling device that determines the type of signal present on its branches, using signal-type-specific control to activate or deactivate signal processing devices only during necessary time slots, and establishes signal paths without duplex filters for time-duplex signals, reducing energy consumption and costs.

Engineering Contradiction Analysis
1Reliability
If permanent amplification is applied to the signal branch for frequency duplex signals, then transmission quality is improved, but energy consumption increases unnecessarily for time-duplex signals
Solution Approach 1:
The amplifier is controlled to operate dynamically based on the detected signal type. For time-duplex signals, the amplifier is activated only during transmission time slots and deactivated during reception time slots. For frequency-duplex signals, the amplifier operates continuously. This dynamic control resolves the contradiction by adapting the amplification behavior to the specific signal characteristics, ensuring transmission quality when needed while minimizing energy consumption when not required.
Solution Approach 2:
The system changes the operational parameters of the amplifier based on the detected signal type. When a time-duplex signal is detected, the amplifier's duty cycle is reduced to only transmission periods. When a frequency-duplex signal is detected, the amplifier operates at full duty cycle. This parameter adaptation resolves the contradiction by optimizing the balance between transmission quality and energy consumption according to the specific communication mode in use.
2Reliability
If a duplex filter is installed in the signal branch for frequency duplex signals, then signal separation is improved, but time-duplex signals are attenuated and device complexity increases
Solution Approach 1:
The system dynamically configures the signal path based on the detected signal type. When a time-duplex signal is detected, the signal path is routed to bypass the duplex filter entirely, avoiding unnecessary attenuation and complexity. When a frequency-duplex signal is detected, the duplex filter is activated to provide proper signal separation. This dynamic path configuration resolves the contradiction by applying the duplex filter only when its functionality is actually required.
Solution Approach 2:
The invention extracts the duplex filter from the mandatory signal path and makes it optional based on signal type. For time-duplex signals, the duplex filter is completely removed from the active signal path, eliminating its harmful attenuating effect and reducing device complexity. For frequency-duplex signals, the filter remains in place to provide necessary signal separation. This extraction approach resolves the contradiction by making the filter's presence conditional rather than permanent.
3Reliability
If signal processing devices are permanently activated, then signal quality is maintained, but energy consumption increases
Solution Approach 1:
The signal processing devices, particularly the amplifier, are activated periodically based on the transmission/reception cycle of time-duplex signals. The amplifier is turned on during transmission time slots when signal quality needs to be maintained and turned off during reception time slots when amplification is not required. This periodic activation resolves the contradiction by providing signal quality enhancement only when necessary while minimizing energy consumption during periods when it is not needed.
Solution Approach 2:
The system uses feedback from signal type detection to control the activation state of signal processing devices. The detection unit identifies whether a time-duplex or frequency-duplex signal is present and provides this information to the control unit, which then adjusts the amplifier's operation accordingly. This feedback mechanism resolves the contradiction by ensuring that signal processing resources are allocated based on actual signal quality requirements rather than permanent activation.
