Solution Overview

Problem

Electronic devices experience transmission delays when connected to both an external device and an audio device during MIMO communication, leading to unsynchronized image data output, which is uncomfortable for users.

Innovation Solution

The electronic device employs a processor to determine if a connected external device is an audio device and switches to a dedicated antenna for stable audio data transmission, using at least one of multiple antennas to communicate with external devices, ensuring real-time data transmission.

1Productivity

If the electronic device performs MIMO communication with an external electronic device using multiple antennas, then the communication bandwidth is increased, but the transmission delay of audio data increases when connected to an audio device

Engineering Contradiction:

Improvecommunication bandwidthVSAvoidaudio data transmission delay

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent segments the communication function by dividing the antenna resources: the first antenna is dedicated to MIMO communication with the external electronic device, while the second antenna is dedicated to audio data transmission to the audio device. This segmentation allows simultaneous operation of both communication functions without mutual interference, resolving the contradiction between maintaining high bandwidth MIMO communication and ensuring low-latency audio transmission.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by assigning different communication characteristics to different antennas: the first antenna is optimized for high-bandwidth MIMO data communication, while the second antenna is optimized for low-latency audio streaming. This localized optimization allows each antenna to perform its specific function at peak efficiency, resolving the contradiction between overall system bandwidth and specific audio transmission timing.

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If the electronic device communicates with both an external electronic device and an audio device simultaneously, then the device functionality is improved, but the synchronization between image data and audio data deteriorates

Engineering Contradiction:

Improvedevice connectivityVSAvoidaudio-video synchronization

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent segments the communication path into two independent channels: one channel (first antenna) for image data transmission to the external electronic device, and another channel (second antenna) for audio data transmission to the audio device. This segmentation creates isolated communication paths that do not interfere with each other, allowing simultaneous operation while maintaining precise synchronization of audio with video, thus resolving the contradiction between multi-device connectivity and synchronization accuracy.
