Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed connection configuration is used in the wireless relay system, then the system structure is simple and stable, but the system cannot flexibly adapt to changes in communication situations
Solution Approach 1:
The patent implements dynamic connection configuration by enabling the wireless relay system to switch between different operational modes (autonomous control mode and relay mode) based on communication situations. The system can dynamically adjust its connection topology and control strategy, allowing flexible adaptation to changing requirements while maintaining manageable complexity through structured mode transitions
2Adaptability or versatility
If batch signal processing is performed by an upper server, then the relay apparatus can be simple with only antenna and transmission/reception functions, but the system lacks flexibility in coping with situation changes
Solution Approach 1:
The patent implements autonomous control functionality within the wireless relay system itself, enabling it to independently make control decisions based on monitored communication situations. The system includes autonomous control units that can operate independently of external batch processing, allowing the relay to self-adjust its behavior according to real-time conditions while maintaining the ability to perform relay functions when needed
3Adaptability or versatility
If the wireless relay system continuously monitors and switches between autonomous control and relay modes, then flexibility is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic monitoring of communication situations rather than continuous monitoring, with the autonomous control units checking conditions at defined intervals. This periodic approach allows the system to maintain adaptability by regularly assessing whether mode switching is needed, while significantly reducing power consumption compared to continuous monitoring and switching operations

AI summary
A wireless relay system includes a first software radio device that performs radio communication with a radio control device and a second software radio device that performs radio communication with a radio terminal. The first software radio device captures, as iq data, a radio signal received from the radio control device, transfers the captured iq data to the second software radio device in real time, converts the iq data transferred from the second software radio device into a radio signal, and transmits the radio signal to the radio control device. The second software radio device captures, as iq data, a radio signal received from the radio terminal, transfers the captured iq data to the first software radio device in real time, converts the iq data transferred from the first software radio device into a radio signal, and transmits the radio signal to the radio terminal.
