Portable Wireless Device Connection Using Attitude Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, establishing a connection between portable devices can be erroneous when their bearings are opposite, leading to unreliable connections without prior knowledge of identification information.
Innovation Solution
A portable wireless communication device acquires and shares attitude information (roll and pitch angles) to determine the alignment and proximity of devices, allowing for intuitive and reliable connection establishment based on bearing and signal strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connection is established based on bearing alone, then connection establishment becomes intuitive and simple, but erroneous connections occur when devices are positioned opposite to each other
Solution Approach 1:
The patent changes the parameter used for connection determination from only bearing to a combination of bearing and attitude information (roll and pitch angles). By adding attitude information as an additional parameter, the system maintains the simplicity of bearing-based operation while eliminating erroneous connections through more precise spatial relationship verification.
Solution Approach 2:
The system uses attitude information from both devices to provide feedback on their relative spatial orientation. This feedback mechanism allows the system to verify whether devices are positioned opposite to each other (indicating potential error) or in the correct orientation for connection, thereby preventing erroneous connections while maintaining intuitive operation.
2Reliability
If manual selection of communication partner is required, then connection reliability is improved through user awareness, but operation complexity and time consumption increase
Solution Approach 1:
The system performs automatic connection establishment based on spatial relationship analysis between devices. Instead of requiring manual user selection, the devices autonomously determine whether to connect by analyzing their own and the partner device's bearing and attitude information, thereby maintaining high reliability while dramatically simplifying the user operation.
Solution Approach 2:
The patent replaces the mechanical interaction of manual device selection with an automated system that uses sensors (electronic compass, gyro sensor) to automatically detect spatial relationships and establish connections. This substitution eliminates the need for user awareness of identification information while maintaining connection accuracy through automated spatial verification.
