Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound playing devices fail to effectively manage connections between electronic devices and sound playing devices, leading to issues where data transmission paths are not properly disconnected, causing subsequent connections to fail due to occupied paths.
Innovation Solution
A sound playing device equipped with a sound module, wireless transmission module, detection module, and control module that distinguishes between audio and data transmission paths using Bluetooth and Bluetooth Low Energy connections, allowing or disabling data paths based on the presence of audio connections to ensure seamless switching and prevent path occupancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If the sound playing device maintains connection via data transmission path after sound transmission path is cut off, then data transmission can continue, but subsequent devices fail to connect due to occupied data path
Solution Approach 1:
The sound playing device performs preliminary detection to check whether the sound transmission path is disconnected before allowing a new device to connect via data transmission path. This preliminary action prevents the data path from being occupied by a previous device, ensuring reliable connection for subsequent devices.
Solution Approach 2:
The system implements feedback mechanism where the sound playing device continuously monitors the connection status of the sound transmission path and uses this information to control whether the data transmission path should be available for new connections. This feedback ensures that data path availability is dynamically adjusted based on current connection state.
2Speed
If the sound playing device immediately connects new devices via sound transmission path, then connection speed is improved, but connection conflicts occur when data path is still occupied
Solution Approach 1:
Before establishing a new sound transmission path connection, the system performs a preliminary check to detect whether the data transmission path is currently occupied. This preliminary detection prevents connection conflicts while maintaining fast connection speed by only adding a simple detection step without complex verification processes.
3Measurement precision
If the device monitors both sound and data transmission paths, then connection management accuracy is improved, but system complexity increases
Solution Approach 1:
The system merges the detection functions for sound transmission path and data transmission path into a unified connection management mechanism. The detection module integrates both path status monitoring, and the control module coordinates their interaction, reducing overall system complexity while maintaining high detection accuracy for both paths.

AI summary
A sound playing device and a connection establishing method thereof are disclosed. The sound playing device comprises a wireless transmission module, a detection module, and a control module. The wireless transmission module is used for establishing a connection with an electronic device via a first or a second wireless transmission path, wherein the first and the second wireless transmission path are used for receiving an audio signal and a data signal respectively. The detection module detects whether the wireless transmission module is connected to the electronic device via the first or the second wireless transmission path. When the detection module detects that the electronic device is to be connected via the second wireless transmission path, it further detects whether the electronic device is connected via the first wireless transmission path. If yes, then the control module enables the connection via the second wireless transmission path.
