Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the radio frequency sensing is made more sensitive to detect presence of people, then the detection capability is improved, but false positives increase
Solution Approach 1:
The patent applies local quality by assigning different sensitivity levels to different sensing areas. The control module divides the monitored space into multiple sensing areas and configures each area with appropriate sensitivity settings based on its specific requirements, allowing high sensitivity in areas where presence detection is critical while maintaining lower sensitivity in areas prone to false positives.
Solution Approach 2:
The patent segments the sensing space into multiple distinct sensing areas, each managed independently with its own sensitivity configuration. This segmentation allows the system to optimize detection parameters locally rather than applying a uniform sensitivity setting across the entire monitored environment, thereby resolving the contradiction between detection capability and false positive rates.
2Measurement precision
If network devices are optimally placed for sensing, then sensing performance is improved, but device placement flexibility is reduced
Solution Approach 1:
The patent implements dynamics by enabling flexible assignment of network devices to different sensing areas based on operational requirements. The control module can dynamically reassign devices to optimize sensing performance for each area without requiring physical relocation of the devices, thus maintaining both high sensing performance and placement flexibility.
Solution Approach 2:
The patent applies universality by designing network devices that can function in multiple sensing areas with different sensitivity requirements. A single network device can be assigned to different sensing areas and configured with appropriate parameters for each area, making the device multi-functional and adaptable to various sensing scenarios without requiring dedicated optimal placement for each area.
3Device complexity
If uniform sensitivity is applied across all sensing areas, then system complexity is reduced, but sensing performance in specific areas deteriorates
Solution Approach 1:
The patent applies local quality by configuring different sensitivity parameters for different sensing areas based on their specific requirements. The control module manages these area-specific configurations, optimizing sensing performance in each area while the system as a whole maintains coordinated operation through centralized control, balancing local optimization with overall system manageability.

AI summary
The invention refers to a control module (130) for controlling a radio frequency sensing. The control module comprises a) a sensing area defining unit (131) for defining two sensing areas (110, 120) by assigning a network device (111, 121) to each area, wherein the assigned network devices contribute to the radio frequency sensing in the respective sensing area, and b) a sensitivity controlling unit (132) for controlling an assigned network device in one of the sensing areas based on a status of a network device and/or based on a sensing result of a sensing area such that a sensing sensitivity and/or sensing mode in a sensing area is configured. Thus, a control module is provided that allows to improve the sensing performance of a radio frequency sensing network (100) without increasing the processing capabilities of the network devices of the radio frequency sensing network.
