Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If radiofrequency sensing is performed in a single sensing area, then the sensing coverage is sufficient, but false positive or false negative detections occur due to interactions with subjects outside the sensing area
Solution Approach 1:
The patent divides the sensing environment into multiple distinct sensing areas (first sensing area and second sensing area) separated by physical separations. Each area has its own baseline characteristics, allowing the system to segment the detection space and attribute events to specific areas, thereby reducing false positives caused by subjects outside the target sensing area.
Solution Approach 2:
The patent introduces baselines as intermediary reference profiles for each sensing area. These baselines serve as mediators that help distinguish between events originating from different areas by comparing current radiofrequency signal characteristics against the established area-specific baselines, thereby improving detection accuracy.
2Productivity
If radiofrequency signals are used for sensing, then motion and changes in the sensing area can be detected, but signals can interact with subjects outside the sensing area leading to detection inaccuracies
Solution Approach 1:
The patent segments the radiofrequency sensing into area-specific detections by establishing distinct baselines for each sensing area. This segmentation allows the system to maintain high sensing productivity while improving reliability by attributing detected events to their correct spatial origin, reducing cross-area interference.
Solution Approach 2:
The patent applies local quality by creating area-specific baselines that reflect the unique radiofrequency characteristics of each sensing area. Each baseline is tailored to local conditions, allowing the system to maintain high detection sensitivity locally while reducing false detections caused by external subjects.

AI summary
The invention refers to an apparatus (130) for configuring a radiofrequency sensing of a radiofrequency sensing network (100) comprising network devices (121, 122, 123), e.g. luminaires, wherein the network is adapted to perform radiofrequency sensing in a first (101, 201 301) and second area (102, 202,. 302) separated by a physical separation (126, 330). The apparatus comprises a providing unit (131) determining a first baseline and a second baseline, wherein the first/second baseline is associated with the first/second area, respectively. The first/second baseline enable a radiofrequency sensing of events in the second area by the network devices. A configuration unit (132) is adapted to configure the radiofrequency sensing to differentiate between events originating from the areas based on the baselines. This allows the present invention to provide an apparatus that allows for a more accurate and reliable 10 radiofrequency sensing in a predefined sensing area.
