Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If path prediction capability is improved by collecting and analyzing multiple VRU messages, then measurement precision of VRU movement paths is improved, but device complexity increases due to the need for path map generation and transmission mechanisms
Solution Approach 1:
The system segments the VRU path prediction into discrete components: collecting VRU messages, determining joints where paths branch, generating node information for each path segment, and creating the VRU path map. This segmentation allows complex path analysis to be broken down into manageable processing steps.
Solution Approach 2:
The system performs preliminary actions by collecting path data from multiple VRU messages before generating the final path prediction. The path map is constructed in advance with node and joint information, enabling subsequent efficient queries and predictions without reprocessing the entire message history.
2Reliability
If the system collects and processes multiple VRU messages to generate accurate path maps, then reliability of VRU movement prediction is improved, but loss of time increases due to data collection and processing requirements
Solution Approach 1:
The system pre-processes VRU messages to extract path data, determine joints, and generate node information before actual prediction is needed. This preliminary action stores the processed information for rapid retrieval, reducing real-time processing time while maintaining high reliability through comprehensive data analysis.
Solution Approach 2:
The system creates a simplified representation (copy) of the complex VRU movement data in the form of a path map with nodes and joints. This copy contains the essential prediction information in a compressed format that can be quickly queried without reprocessing the original message data, thus reducing time loss while preserving reliability.
