Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Bluetooth communication technology is used for ear-wearable devices to exchange data, then wireless connectivity and data transmission are enabled, but synchronization issues and limited data conversion capabilities occur
Solution Approach 1:
The patent introduces an intermediary device (such as a smartphone or audio device) that acts as a mediator between the audio source and the ear-wearable device. This intermediary receives audio data, performs necessary conversions and processing, then transmits synchronized data to the ear-wearable device, resolving both the conversion capability limitation and synchronization accuracy issues
Solution Approach 2:
The system segments the audio data transmission process into multiple channels: audio data stream, synchronization signal stream, and control signal stream. By separating these functions into distinct data streams transmitted through different Bluetooth protocols (BR/EDR for audio, BLE for synchronization), the system achieves both versatile data conversion and reliable synchronization
2Adaptability or versatility
If ear-wearable devices output only audio data, then simple playback function is provided, but user interaction and flexibility are limited
Solution Approach 1:
The ear-wearable device is designed with multi-functionality to output various types of data including audio, text, images, and haptic feedback in addition to traditional audio playback. The device incorporates multiple output interfaces and processing units that enable it to handle diverse data formats, significantly enhancing user interaction flexibility while distributing processing complexity across different functional modules
3Adaptability or versatility
If speech recognition decoding is performed to convert audio data to text, then language accessibility is improved, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary actions by pre-processing audio data and preparing multiple language translation versions in advance during periods when real-time processing is not critical. The intermediary device caches commonly used phrases and maintains pre-computed translations, so when speech recognition is triggered, the system can quickly retrieve and output results with minimal delay, thus supporting multiple languages while reducing processing time
Data Source
AI summary
An electronic device and method for synchronized data output include establishing a communication link with an external electronic device; receiving advertising data from a source electronic device; transmitting synchronization information associated with first data obtained from the advertising data to the external electronic device; obtaining second data corresponding to the first data; and outputting the second data at a time synchronized with an output timing of the first data by the external electronic device. The second data may include text corresponding to voice through speech recognition decoding, vibration patterns corresponding to sound, or visual data. The device may receive audio data in a different language and convert it to speech recognition text, with language selection based on device settings. The device may display inquiries for user consent and determine output based on user settings.
