A method using a mobile device to receive an identifier from a tagged device, access proximity information, perform a wireless ranging protocol to determine distance and angle, and establish a control session if the distance is within specified limits, allowing for automatic device control without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual device selection from a list is used, then device control can be established, but user interaction complexity and error probability increase
Solution Approach 1:
The system enables automatic device selection by having the mobile device autonomously determine proximity to tagged devices using wireless ranging protocols. The control session is automatically established with the nearest tagged device without requiring manual user intervention, allowing the system to serve itself in the device selection process.
Solution Approach 2:
The patent replaces the manual mechanical interaction of selecting devices from a list with an automated electronic system. The mobile device uses wireless ranging protocols to automatically detect and determine proximity to tagged devices, substituting manual user actions with electronic automation based on measured distance and angle data.
2Extent of automation
If automatic control session establishment is implemented, then user interaction is reduced, but system complexity increases
Solution Approach 1:
The patent introduces proximity information and wireless ranging protocols as intermediary mechanisms between the mobile device and tagged devices. These intermediaries enable automatic control session establishment by providing the necessary distance and angle data, bridging the gap between simple device presence and automated connection without requiring complex direct device-to-device communication protocols.
3Measurement precision
If proximity-based automatic connection is used, then device control accuracy improves, but measurement and detection difficulty increases
Solution Approach 1:
The system performs preliminary actions by pre-establishing proximity information and distance limits for tagged devices before control session establishment. The mobile device pre-determines which devices are within acceptable proximity ranges using wireless ranging protocols, preparing the groundwork for automatic connection decisions without requiring complex real-time measurements during the actual connection process.
