Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle display systems face inefficiencies in transmitting and generating navigation information, particularly in high-quality three-dimensional displays, due to the need for multiple processing units and limited transmission bandwidth, which complicates real-time data processing and image consistency.
Innovation Solution
A method utilizing a metadata structure for navigation information, transmitted via a communication interface, to determine pixel values for digital images and graphic elements, allowing for efficient image generation in a single processing unit, thereby reducing bandwidth requirements and enhancing real-time display capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If navigation information is transmitted as character commands, then transmission bandwidth is consumed, but image quality and detail are reduced
Solution Approach 1:
The patent extracts only the essential semantic information (driving action and distance) from complete navigation instructions and transmits them as structured metadata. This extraction allows high-quality navigation information to be conveyed with minimal bandwidth consumption by omitting redundant descriptive elements.
Solution Approach 2:
The patent changes the transmission format from character-based text to structured metadata with specific parameters (driving action, distance). This parameterization enables efficient bandwidth utilization while preserving the essential information needed for high-quality image generation at the receiving end.
2Productivity
If images are generated in multiple processing units, then computational distribution is achieved, but image consistency and processing complexity increase
Solution Approach 1:
The patent merges the image generation function into a single processing unit that receives structured metadata. This consolidation eliminates the complexity of coordinating multiple processing units while maintaining high productivity, as the single unit can efficiently generate consistent images without inter-unit communication overhead.
Solution Approach 2:
The patent performs preliminary structuring of navigation information into standardized metadata format before transmission. This preliminary action enables the receiving processing unit to directly generate images without additional processing or coordination, simplifying the system architecture while maintaining efficiency.
3Manufacturing precision
If complex three-dimensional models are generated in real-time, then display quality is improved, but processing load and bandwidth requirements increase
Solution Approach 1:
The patent extracts only the critical parameters (driving action, distance) needed for three-dimensional model generation and transmits them as compact metadata. This extraction reduces the processing load and bandwidth requirements while enabling the receiving unit to generate high-quality three-dimensional displays in real-time.
