Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If audio output is provided through built-in audio output unit of mobile terminal, then audio data can be reproduced, but sound field is deteriorated due to size of mobile terminal
Solution Approach 1:
The patent extracts the audio output function from the mobile terminal by transmitting audio data to external audio output devices (TV, monitor, PC, audio player) through wireless communication. This allows the mobile terminal's limited audio capabilities to be supplemented by external devices with superior sound fields, effectively resolving the contradiction between compact size and audio quality.
2Illumination intensity
If earphones or headphones are used to listen to music through mobile terminal, then audio quality can be improved, but user convenience is reduced and additional accessories are required
Solution Approach 1:
The patent implements multi-functionality by enabling the mobile terminal to output audio to various types of external devices (TV, monitor, PC, audio player) without requiring earphones or headphones. This universal compatibility allows users to leverage existing audio equipment for high-quality sound while maintaining convenience, as no additional accessories are needed.
3Illumination intensity
If audio data is transmitted to external audio output device, then sound field is improved, but wireless communication reliability must be ensured
Solution Approach 1:
The patent employs feedback mechanisms where the mobile terminal monitors the repeated wireless signal from the audio output device and adjusts transmission based on signal strength thresholds. This ensures reliable wireless communication by maintaining connection stability while enabling high-quality audio output to external devices.
