Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic control is implemented without requiring user to carry mobile device, then user experience is improved, but system complexity increases due to need for human sensing capabilities
Solution Approach 1:
The system enables automatic control by having the IoT device itself perform sensing and control operations without requiring user intervention or mobile device carrying. The device uses its integrated human sensing capabilities to detect user presence and automatically executes control actions based on detected scenarios, making the system serve itself rather than requiring external mobile device control.
Solution Approach 2:
The IoT device is equipped with multiple functional modules including ultra-wide band module for positioning, millimeter-wave radar module for human sensing, and communication modules for network connectivity. This multi-functionality allows a single device to perform sensing, communication, control, and processing tasks that would otherwise require separate components, reducing overall system complexity while improving ease of operation.
2Extent of automation
If multiple scenarios are detected and linked to different tasks, then automation capability is improved, but conflict resolution complexity increases when scenarios overlap
Solution Approach 1:
The system pre-establishes linkage rules that define task priorities for different scenarios before conflicts occur. When multiple scenarios are detected simultaneously, the predetermined priority relationships in the linkage rules automatically determine which task executes, eliminating the need for complex real-time conflict resolution logic and simplifying the automation decision-making process.
3Ease of operation
If human sensing modules are integrated into IoT devices, then ease of operation is improved, but manufacturing cost increases
Solution Approach 1:
The patent integrates multiple sensing modules (ultra-wide band module, millimeter-wave radar module) and communication modules into a single IoT device structure. By merging these functions into one unified device rather than using separate components, the system reduces overall component count, simplifies assembly processes, and lowers manufacturing costs while maintaining advanced automatic control capabilities.

AI summary
A human sensing-based automatic control method, an electronic device, and a system are provided, so that when a user approaches an IoT device, the IoT device automatically performs an operation, to improve user experience. The system includes a hub device, a first electronic device (100), and a second electronic device (300). The first electronic device (100) includes an ultra-wide band module and a millimeter-wave radar module, and is configured to measure a human body position and a position of the second electronic device (300) in a house, to determine a current scenario in the house. When the first electronic device (100) detects a plurality of scenarios, and there are conflicting tasks in the plurality of scenarios, the hub device determines a to-be-performed task based on a priority of each scenario. The hub device may further count an activity track, duration of an activity, and the like of a user in each room/region in the house based on the human body position detected by the first electronic device (100).
