Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple audio devices are used together with one device collecting audio data, then the audio data can be transmitted to the electronic device, but the audio data quality deteriorates due to concentrated noise picked up by the microphone
Solution Approach 1:
The patent implements dynamic role switching between audio devices based on real-time noise level detection. The audio devices can dynamically change their functionality from audio collection to audio output or vice versa, depending on which device experiences lower noise levels. This dynamic adaptation resolves the contradiction by allowing the system to optimize audio quality in real-time despite varying noise conditions across multiple devices.
Solution Approach 2:
The system monitors noise level parameters of each audio device and changes the operational parameters (role assignment) based on these measurements. When noise levels exceed certain thresholds, the system switches the collecting device role to a different audio device with better noise conditions. This parameter-based decision-making resolves the quality degradation caused by fixed role assignment in noisy environments.
2Reliability
If the audio device switches roles with the external audio device based on noise levels, then the overall quality of recorded audio data is improved, but the device complexity increases due to role switching mechanisms
Solution Approach 1:
The patent employs feedback mechanisms where each audio device continuously monitors its own noise levels and communicates this information to the system controller. Based on this feedback, the system automatically adjusts role assignments without requiring complex manual intervention or sophisticated decision algorithms. The feedback loop simplifies the complexity by using straightforward noise-level-threshold comparisons to trigger role switches.
Solution Approach 2:
Each audio device autonomously monitors its own noise conditions and can independently determine when role switching is beneficial. The devices self-manage their functionality based on local noise measurements, reducing the need for complex centralized control mechanisms. This self-service approach resolves the contradiction by distributing the decision-making logic to individual devices rather than requiring a complex central controller.

AI summary
An audio device and method are disclosed. The audio device includes a microphone, a communication circuit, and a processor. The processor implements the method, including: establishing a communication link with an electronic device via the communication circuit, transmitting information related to the communication link to an external audio device via the communication circuit, detecting a first level of noise included in a first audio data collected via the at least one microphone, identifying a second level of noise of the external audio device, when the first level of noise satisfies a predesignated first condition, and controlling the external audio device to transmit second audio data collected by the external audio device to the electronic device, when the second level of noise of the external audio device meets a predesignated second condition different from the predesignated first condition.
