Engineering Contradiction Analysis
1Reliability
If wireless relay devices dynamically switch communication connections based on load balancing, then communication stability and traffic safety are improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic connection switching between wireless relay devices based on real-time load conditions and radio wave quality measurements. The base station and relay devices dynamically adjust communication paths by switching connection destinations of terminal devices according to changing network conditions, thereby improving communication stability without requiring complex manual intervention.
Solution Approach 2:
The patent employs feedback mechanisms where relay devices report their communication loads and radio wave quality measurements to the base station. The base station uses this feedback information to make informed decisions about connection switching, selecting optimal paths based on measured parameters and maintaining reliable communication while managing system complexity through automated feedback-driven control.
2Reliability
If dynamic path switching is implemented for load balancing, then communication stability improves, but measurement and detection difficulty increases
Solution Approach 1:
The patent implements self-service measurement where relay devices autonomously measure and report their own communication loads and radio wave quality to the base station. This self-measurement mechanism eliminates the need for complex external monitoring systems, reducing measurement and detection difficulty while enabling accurate load balancing decisions based on real-time relay device conditions.
3Reliability
If connection switching is performed based on load and radio wave quality, then traffic safety improves, but processing time increases
Solution Approach 1:
The patent implements preliminary measurements of radio wave quality and continuous monitoring of communication loads by relay devices. These pre-measured and continuously updated parameters are readily available when switching decisions are needed, eliminating the need for time-consuming real-time measurements during connection switching and enabling rapid, informed decisions that improve traffic safety without significant time delay.
