Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices with small displays face challenges in maintaining image quality due to network state degradation, as they struggle to dynamically adjust image bitrates based on display size and network conditions, leading to potential quality degradation and excessive network usage.
Innovation Solution
An electronic device with a communication interface and processor that receives images from multiple external devices, determines bitrates based on display region sizes, and transmits this information to adjust image quality dynamically, preventing network state degradation and optimizing image quality.

Engineering Contradiction Analysis
1Area of stationary object
If the electronic device receives images from multiple external electronic devices and displays them simultaneously, then the user can view content from multiple devices on a larger display, but the network state degrades due to excessive network usage
Solution Approach 1:
The electronic device dynamically changes the bitrate parameter of received images based on network conditions and display region sizes. The processor adjusts the bitrate parameter to optimize the balance between image quality and network resource consumption, preventing network state degradation while maintaining acceptable display quality on multiple devices simultaneously
2Manufacturing precision
If the electronic device monitors network state in real time and adjusts image qualities after network degradation occurs, then the image quality can be adapted to current conditions, but the network state cannot be prevented from degrading
Solution Approach 1:
The electronic device performs preliminary actions by proactively adjusting image bitrates based on predicted network conditions and display requirements before network degradation occurs. The processor calculates appropriate bitrates in advance based on display region sizes and transmits these parameters to external devices, preventing network state degradation rather than merely reacting to it
Solution Approach 2:
The electronic device implements a feedback mechanism where the processor continuously monitors network conditions and adjusts image bitrate parameters accordingly. The system transmits bitrate information back to external electronic devices, creating a closed-loop control system that maintains image quality while adapting to network conditions in real time
