Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for encoding and decoding dynamic location references in navigation systems are inefficient, particularly due to differences in map data models and attributes between vendors, leading to errors and increased computational load, especially in smaller devices.
Innovation Solution
A method that computes a focusing factor based on encoded location reference information and enhances it with this factor for transmission, allowing for faster and more accurate path reconstruction on remote devices, reducing the search area and processing nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If detailed location reference information is transmitted to enable accurate path reconstruction, then decoding accuracy is improved, but the computational load and processing time increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-computing and transmitting focusing factors along with location reference information. These focusing factors are calculated in advance at the source, enabling the receiving device to quickly identify and process only relevant path segments without performing exhaustive searches, thus reducing decoding time while maintaining accuracy
Solution Approach 2:
The patent implements local quality by transmitting focusing factors that highlight specific local areas or segments of the path that require detailed processing. Instead of uniformly processing entire paths, the receiving device concentrates computational resources on locally identified relevant segments, improving decoding efficiency without sacrificing accuracy
2Reliability
If comprehensive location reference data is transmitted to all devices, then decoding success rate is improved, but the data transmission volume and processing load increase
Solution Approach 1:
The patent applies the extraction principle by isolating and transmitting only the essential focusing factors that are most critical for accurate path reconstruction. Rather than transmitting complete path data or all possible location reference information, the system extracts and transmits only the key parameters needed for efficient and accurate decoding at the receiving end
Solution Approach 2:
The patent implements parameter changes by transforming detailed location reference information into condensed focusing factor parameters. This parameter transformation reduces the data volume significantly while preserving the essential information needed for accurate path reconstruction, as the focusing factors encode the critical spatial relationships in a compact form
3Device complexity
If path reconstruction is performed on remote devices with limited processing power, then device complexity is reduced, but decoding speed and success rate decrease
Solution Approach 1:
The patent introduces focusing factors as intermediary elements that facilitate efficient path reconstruction on resource-constrained devices. These focusing factors act as a bridge between the complex path data and the limited processing capabilities of remote devices, enabling accurate and fast decoding without requiring high computational power
