Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large number of sensing transmitters and receivers are deployed to cover all desired locations, then sensing coverage is improved, but radio resource consumption increases significantly
Solution Approach 1:
The patent enables sensing receiver devices to perform dual functions: receiving communication packets for normal communication purposes and simultaneously performing sensing measurements on the same packets. This eliminates the need for separate dedicated sensing packets, thereby reducing radio resource consumption while maintaining comprehensive sensing coverage across multiple locations.
2Area of stationary object
If sensors are spread out over a large area to achieve coverage, then coverage is improved, but measurement reliability deteriorates
Solution Approach 1:
The patent introduces a sensing coordination device that acts as an intermediary to manage and coordinate sensing operations across multiple distributed receivers. This coordinator optimizes the selection of sensing receiver devices for specific time intervals and manages the transmission of communication packets, ensuring that measurements are performed efficiently and reliably across the entire coverage area without requiring excessive packet transmissions from each individual sensor.
3Measurement precision
If dedicated sensing packets are transmitted for each sensing operation, then measurement accuracy is improved, but radio resource overhead increases
Solution Approach 1:
The patent merges the communication function and sensing measurement function into a single integrated process. Instead of transmitting separate dedicated sensing packets, the system uses existing communication packets for both communication and sensing purposes. The sensing receiver devices perform measurements on these multi-functional packets, thereby maintaining measurement accuracy while eliminating the radio resource overhead associated with dedicated sensing transmissions.
