In-Vehicle Shared Image Display Under Variable Processing Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle devices face challenges in displaying shared images from mobile terminals without interruptions, especially when processing loads are high, despite having high processing capabilities.
Innovation Solution
The vehicle is equipped with a display unit, monitoring unit, and display controller that monitor processing loads and adjust display modes, such as converting 3D images to 2D or reducing frame transitions, to manage data according to available processing capacity, preventing temporary image display interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the in-vehicle device displays high-resolution shared images with high frame transitions, then the image quality is improved, but the processing load increases causing display interruptions
Solution Approach 1:
The patent applies dynamics by making the display parameters (resolution and frame transition rate) adjustable and adaptive rather than fixed. The control unit dynamically changes these parameters based on real-time processing load monitoring, allowing the system to optimize between image quality and display continuity under varying operational conditions
Solution Approach 2:
The patent implements parameter changes by modifying display characteristics (resolution and frame transition rate) according to processing load state. When processing load exceeds thresholds, the system changes these parameters to reduce computational demand, preventing display interruptions while maintaining acceptable image quality
2Loss of information
If the in-vehicle device processes large amounts of shared image data, then the image fidelity is improved, but the processing time increases causing delays
Solution Approach 1:
The system changes processing parameters (resolution and frame rate) based on processing load monitoring. When processing time exceeds thresholds, the control unit adjusts these parameters to reduce data volume, thereby decreasing processing time while maintaining sufficient image fidelity for the given conditions
3Manufacturing precision
If the display unit maintains high processing capability, then the image quality is improved, but the system complexity increases
Solution Approach 1:
The patent applies self-service by implementing automatic monitoring and control mechanisms that adjust display parameters based on processing load without requiring manual intervention. The control unit autonomously monitors processing time and resolution, and adjusts parameters accordingly, reducing system complexity while maintaining high processing capability
