Solution Overview
Problem
Existing IoT device management systems face challenges in efficiently designating and controlling device groups within a house, particularly due to limitations in communication range and spatial separation, leading to difficulties in coordinating multiple IoT devices across different spaces.
Innovation Solution
An electronic device and method that designates a device group based on the intensity of a response signal from external devices, using sound signals or other communication methods to identify and control devices within the same spatial area, allowing for more effective control of IoT devices across various spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices are divided into separated spaces for control, then communication reliability is improved, but device coordination complexity increases
Solution Approach 1:
The system segments devices into different spatial groups (first space and second space) based on signal intensity thresholds. Devices in the first space form a first device group, while devices in the second space form a second device group. This segmentation allows reliable communication within each group while reducing overall system complexity through organized structure.
Solution Approach 2:
The electronic device acts as an intermediary that receives signals from external devices, determines their spatial location based on signal intensity, and coordinates communication between different device groups. This intermediary function simplifies the coordination complexity by centralizing the decision-making process for device grouping and signal routing.
2Area of stationary object
If signal transmission range is extended to cover more devices, then device coverage is improved, but signal intensity precision deteriorates
Solution Approach 1:
The system applies different signal intensity thresholds for different spatial zones. Devices are evaluated against threshold values that are specific to their local spatial context (first space vs. second space). This local quality approach allows the system to maintain signal intensity precision within each local area while extending overall device coverage across multiple spaces.
