Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If high precision map information from different manufacturers is integrated into autonomous driving control systems, then the system can utilize diverse map data sources, but extensive manpower is required to verify consistency and format compatibility
Solution Approach 1:
The patent introduces a standardized map information storage unit that acts as an intermediary between diverse external map data sources and the autonomous driving control device. This storage unit provides a unified data structure and interface that automatically adapts to different map formats, eliminating the need for manual verification and conversion of each map source while maintaining compatibility across different manufacturers' data formats
Solution Approach 2:
The map information storage unit is designed with universal functionality to handle multiple map data formats from different manufacturers through a single unified interface. The storage unit can store various types of map information (road data, POI data, elevation data, etc.) in a standardized structure, allowing the autonomous driving control device to access diverse map sources without requiring separate processing for each format
2Ease of manufacture
If map formats are independently developed by each map company, then each company can optimize their own data structure, but application developers must understand each format separately, increasing development man-hours
Solution Approach 1:
The standardized map information storage unit serves as an intermediary layer between the diverse map data formats and the application logic. It automatically handles format conversion and standardization, so developers only need to interact with the unified interface without needing to understand the underlying format complexities of different map providers
Solution Approach 2:
The patent creates a standardized copy or representation of map information in the storage unit that is independent of the original format. This standardized copy contains all necessary information in a unified structure, allowing applications to work with a single format representation regardless of the source format, thereby reducing the need to understand multiple formats
Data Source
