Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional Bluetooth audio technology is used for one-to-one connection, then device compatibility is maintained, but support for multiple devices and audio data transmission/reception is inadequate
Solution Approach 1:
The patent implements dynamic state management where the central device adapts its behavior based on the current states of peripheral devices. The system transitions between different operational modes (standby, configured, streaming) depending on the states of connected devices, enabling flexible support for multiple devices while maintaining reliable audio transmission through state-aware decision making
Solution Approach 2:
The patent employs feedback mechanisms where the central device obtains state information from peripheral devices and uses this information to determine appropriate state transitions. This feedback loop ensures that audio data transmission is performed only when both devices are in suitable states, maintaining reliability while supporting versatile multi-device configurations
2Ease of operation
If state transition is performed without considering another device's current state, then procedure simplicity is maintained, but unnecessary procedures are executed increasing power consumption
Solution Approach 1:
The patent applies preliminary action by obtaining the state information of the other device before initiating state transition procedures. This advance check allows the system to determine whether state transition is necessary, avoiding unnecessary procedures and reducing power consumption while maintaining operational simplicity through automated state-aware decision making

AI summary
The present disclosure relates to a method, a device, and a computer program for controlling and managing a state of a peripheral device in a wireless communication system, and a recording medium therefor. According to an embodiment of the present disclosure, a method for changing an audio stream session-related state may include the steps of: acquiring information relating to a current audio stream session-related state of a second device before a first device in a first audio stream session-related state performs transition of an audio stream session-related state; determining a second audio stream session-related state of the first device at least on the basis of the current audio stream session-related state of the second device; and performing the transition of the audio stream session-related state by the first device on the basis of the second audio stream session-related state.
