Bluetooth Group Connection Stability via Automatic Role Reconfiguration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Bluetooth communication systems for groups of three or more devices require users to manually adjust connections to maintain optimal communication distance, which is cumbersome and reduces usability, as the alignment of devices affects communication quality and distance.
Innovation Solution
A communication apparatus with a connection form determination unit that assesses the stability of connections between devices using signal strength indicators and adjusts the connection form to optimize communication, automatically reconfiguring the master and slave roles as needed to maintain stable communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manually adjust connection forms to maintain optimal communication distance, then communication stability is improved, but ease of operation deteriorates
Solution Approach 1:
The communication apparatus automatically determines connection forms and performs role changes between master and slave devices without user intervention. The system monitors communication states and autonomously reconfigures connections to maintain optimal communication distance, eliminating the need for users to manually adjust settings while preserving communication stability.
Solution Approach 2:
The system continuously monitors communication states between devices and uses this feedback to automatically determine when role changes or reconfigurations are needed. By detecting changes in communication quality and device positions, the system dynamically adjusts connection forms to maintain optimal performance without user input.
2Adaptability or versatility
If connection form is changed to adapt to user alignment changes, then adaptability is improved, but device complexity increases
Solution Approach 1:
The communication apparatus autonomously monitors its own communication state and automatically determines when connection form changes are needed. The system performs self-diagnosis of communication quality and autonomously executes role changes between master and slave devices, adapting to user alignment changes without requiring complex user interfaces or manual configuration procedures.
3Ease of operation
If automatic connection form determination is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The communication apparatus integrates automatic connection form determination functionality directly into the device, enabling it to autonomously monitor communication states and perform role changes without user intervention. This self-service capability simplifies user operation while the underlying complexity is managed through automated algorithms that determine optimal connection configurations based on real-time communication quality assessment.

AI summary
A desirable connection form in consideration of a radio wave state is caused to be formed among three or more communication apparatuses. Group list information indicating three or more communication apparatuses, including local equipment, that have been set as a group for performing wireless communication is referred to so as to grasp communication apparatuses that have been set as the group. Then, a value indicating a degree of stability of communication between respective communication apparatuses indicated in the group list information is obtained, and a new connection form to which a change is desirably performed is determined by using the value indicating the degree of stability of communication between the respective communication apparatuses. Then, processing is performed for changing a connection state of respective communication apparatuses included in the group to the new connection form.
