Audio Device Call-End Prompt for Wireless Link Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio devices, such as Bluetooth speakerphones in shared meeting rooms, often maintain unintended wireless links after a call ends, leading to new calls being inadvertently directed to the wrong device, causing unintended connections and disconnections.
Innovation Solution
The audio device detects a call-end request and prompts the user through auditory, visual, or tactile notifications to decide whether to maintain or disconnect the wireless link, allowing users to choose whether to keep or close the connection, thereby preventing unintended wireless links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the wireless link is automatically maintained after call ends, then connection stability is improved, but unintended connections to wrong devices occur
Solution Approach 1:
The system performs preliminary action by prompting the user before automatically disconnecting the wireless link. The prompt is displayed at call-end giving the user an opportunity to confirm or cancel disconnection, preventing unintended disconnections while allowing automatic disconnection when no response is received.
2Object-affected harmful factors
If the wireless link is automatically disconnected at call-end, then unintended connections are prevented, but connection stability deteriorates
Solution Approach 1:
The system performs preliminary action by prompting the user before automatically disconnecting the wireless link. The prompt is displayed at call-end giving the user an opportunity to confirm or cancel disconnection, preventing unintended disconnections while allowing automatic disconnection when no response is received.
Solution Approach 2:
The system implements feedback by monitoring user response to the disconnection prompt within a predetermined time window. If the user responds affirmatively or does not respond within the time limit, the system proceeds with disconnection. If the user responds negatively, the system maintains the connection, thus adapting the disconnection action based on user feedback.
3Measurement precision
If user prompt is added at call-end, then connection control accuracy is improved, but device complexity increases
Solution Approach 1:
The system implements self-service by using the existing display interface of the audio device to present the disconnection prompt to the user. The device utilizes its own built-in display capabilities without requiring external devices or additional hardware interfaces, thereby improving connection control accuracy while minimizing increases in device complexity.
