Smart Device Grouping via Signal Strength Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of smart home appliances increases, controlling multiple devices simultaneously becomes inefficient, requiring users to select and turn off each device individually, leading to low control efficiency.
Innovation Solution
A smart device grouping system that uses a grouping terminal to send a transmission power value to selected devices, allowing them to broadcast signals and generate signal strength information, which is then used to group devices based on signal strengths, enabling automatic grouping and collective control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple smart devices are controlled individually through mobile terminal selection, then each device can be precisely controlled, but control efficiency deteriorates as the number of devices increases
Solution Approach 1:
The patent segments the control process into two phases: (1) automatic grouping phase where devices are clustered based on signal strength measurements, and (2) batch control phase where control commands are applied to groups simultaneously. This segmentation resolves the contradiction by automating the grouping operation while maintaining precise device-level control within each group.
Solution Approach 2:
The system implements self-service through automatic device grouping based on signal strength measurements. Devices automatically form groups without user intervention by measuring signal strengths and being clustered by the control device, eliminating the need for manual selection and grouping operations while maintaining control precision.
2Productivity
If automatic grouping based on signal strength is implemented, then control efficiency improves through batch operations, but device complexity increases due to additional grouping mechanisms
Solution Approach 1:
The mobile terminal serves multiple functions: it acts as both the control device for issuing commands and the grouping device for automatic clustering based on signal strength measurements. This multi-functionality reduces system complexity by eliminating the need for separate dedicated grouping hardware while maintaining automatic grouping capabilities that improve control efficiency.
Solution Approach 2:
The system uses signal strength as a dynamic parameter for automatic grouping. By measuring and comparing signal strength values, devices are automatically clustered into groups without requiring complex configuration or user input. This parameter-based approach simplifies the grouping mechanism while enabling efficient batch control operations.
