Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If trigger devices continuously send sensing messages to access point devices, then sensing capability is maintained, but radio resources are occupied and sensing efficiency is reduced
Solution Approach 1:
The patent implements periodic sensing message transmission instead of continuous transmission. Trigger devices send sensing messages at predetermined intervals, and the access point device determines channel state information based on these periodic messages. This reduces radio resource occupation while maintaining sensing capability through the periodic updates of channel state information.
Solution Approach 2:
The patent dynamically adjusts the working state of trigger devices based on channel determination results. When channel state information indicates good channel conditions, trigger devices may increase transmission frequency or bandwidth. When channel conditions are poor, transmission frequency is reduced. This dynamic adaptation optimizes sensing efficiency while maintaining reliability.
2Measurement precision
If trigger devices send sensing messages frequently, then channel state information is updated continuously, but radio resource occupation increases
Solution Approach 1:
The patent applies partial action by sending sensing messages only when necessary rather than continuously. The access point device evaluates channel determination results and determines whether additional sensing messages are needed. This partial transmission approach maintains adequate channel state information accuracy while significantly reducing radio resource occupation compared to continuous transmission.
3Area of stationary object
If multiple trigger devices operate simultaneously, then coverage range is expanded, but resource conflict and interference increase
Solution Approach 1:
The patent segments the operation of multiple trigger devices by assigning different time slots, frequency bands, or spatial resources to different devices. The access point device coordinates multiple trigger devices to operate in a segmented manner, allowing coverage expansion while minimizing resource conflicts and interference between devices through structured resource allocation.
