Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience reduced transmission and reception volumes and difficulties in video communication due to increased distance between the electronic device and the user's face, leading to inconvenient voice communication and swift communication challenges.
Innovation Solution
An electronic device with a processor, memory, and program that determines the distance to the user's face and adjusts video communication data variables such as transmission volume, microphone sensitivity, screen size, and camera magnification to optimize video communication services based on this distance.

Engineering Contradiction Analysis
1Ease of operation
If the user holds the electronic device at a greater distance from their face, then the user can view the screen more comfortably, but the transmission volume and voice clarity are reduced
Solution Approach 1:
The patent applies dynamics by making the transmission volume weight dynamically adjustable based on the detected distance between the user's face and the electronic device. The system automatically modifies the transmission volume weight according to distance measurements, transitioning from a static to a dynamic volume control mechanism that adapts to varying usage conditions.
Solution Approach 2:
The patent implements parameter changes by modifying the transmission volume weight parameter based on the distance parameter. When the distance exceeds a reference value, the system changes the transmission volume weight to compensate for signal attenuation, thereby maintaining voice transmission quality across different distances.
2Reliability
If the user holds the electronic device closer to their face, then voice transmission quality improves, but the user must talk louder to be heard
Solution Approach 1:
The system changes the transmission volume weight parameter based on the detected distance, reducing the need for users to increase their vocal effort. When the device is held closer, the transmission volume weight is adjusted to prevent excessive amplification, while at greater distances, the weight increases to compensate for signal loss.
Solution Approach 2:
The patent employs feedback by continuously monitoring the distance between the user's face and the electronic device and automatically adjusting the transmission volume weight in response. This closed-loop control ensures that the system adapts to changing conditions without requiring manual intervention from the user.
3Ease of operation
If the distance between the electronic device and user's face increases, then screen viewing is more comfortable, but communication swiftness decreases
Solution Approach 1:
The system dynamically adjusts the transmission volume weight based on real-time distance measurements, enabling swift adaptation to changing usage conditions. This dynamic response maintains communication efficiency regardless of the distance between the device and the user's face.
Solution Approach 2:
The patent applies preliminary action by pre-establishing reference distance values and corresponding transmission volume weight configurations. When a distance change is detected, the system can quickly apply the appropriate weight adjustment without requiring complex real-time calculations, thereby maintaining communication swiftness.
