Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user carries a mobile device to control an IoT device, then the user can implement automatic control through communication and sensing, but the user experiences inconvenience when forgetting to carry the mobile device
Solution Approach 1:
The patent introduces a hub device as an intermediary between the user and the IoT device. The hub device includes a human sensing module that can detect user presence without requiring the user to carry a mobile device. When the user approaches the IoT device, the hub device receives the sensing signal, determines the user's location, and automatically triggers the IoT device to perform the intended operation, thus eliminating the need for the user to carry a mobile device while maintaining reliable control functionality
Solution Approach 2:
The system enables the IoT device to automatically respond to user presence through the hub device's human sensing capability. The IoT device self-adjusts its operation based on the detected user location, performing actions such as turning on lights or adjusting air conditioning without requiring manual intervention or a mobile device, thereby improving both convenience and reliability
2Ease of operation
If the IoT device automatically performs operation when user approaches, then user convenience is greatly improved, but additional hardware (such as camera) would be needed on the IoT device
Solution Approach 1:
The patent merges the human sensing functionality into the hub device rather than adding it to each IoT device. The hub device integrates the human sensing module, location determination module, and communication module into a single centralized unit. This allows multiple IoT devices to benefit from the shared sensing capability without each device needing its own sensors or cameras, thus improving user convenience while avoiding increased hardware complexity at the IoT device level
Solution Approach 2:
The hub device serves multiple functions: it acts as a communication hub for IoT devices, a human sensing station, a location determination system, and an automatic control trigger. This multi-functional design eliminates the need for each IoT device to have dedicated sensing hardware, as the hub device provides these services universally to all connected IoT devices, thereby maintaining simplicity while enabling convenient automatic control

AI summary
The system includes a hub device, a first electronic device, and a second electronic device. The first electronic device includes a first ultra-wide band module and a millimeter-wave radar module. Position information of the second electronic device and position information of a user are obtained based on position measurement for the second electronic device, measurement for a human body position, and conversion that are performed by the first electronic device. At least one second electronic device automatically performs a preset operation based on the position information of the user and the position information of the second electronic device.
