Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a projection type is used to display curved mapped areas on a flat map, then the mapped area can be displayed, but skewed coordinates are introduced compared to real-world shapes
Solution Approach 1:
The system segments the curved mapped area into multiple thumbnail panels, each representing a specific geographic region. By dividing the large curved map into smaller discrete panels, the system can apply appropriate projection transformations to each panel while maintaining overall geographical accuracy and reducing cumulative distortion effects.
Solution Approach 2:
The system creates thumbnail copies of the area map data, projecting panel corners onto the area map and extracting representative samples. These thumbnail panels serve as simplified copies that preserve key geographical relationships and situational awareness while eliminating the need to display the entire curved map at full resolution.
2Adaptability or versatility
If multiple maps based on different projection types are used, then comprehensive geographical coverage is achieved, but coordinate inconsistency and distortion increase
Solution Approach 1:
The system creates a universal thumbnail display framework that can accommodate multiple maps with different projection types. By projecting panel corners from various chart data sources onto a common area map and generating standardized thumbnails, the system provides a unified view that maintains coordinate consistency across diverse geographical data sources.
Solution Approach 2:
The system transforms coordinate parameters from different projection types into a common reference framework. By changing the projection parameters and applying extraction mappings, the system reconciles coordinate inconsistencies between maps based on different projection types while preserving essential geographical information.
3Loss of information
If thumbnail panels are generated by projecting panel corners and extracting area map data, then situational awareness is improved, but processing complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-projecting panel corners onto the area map and pre-determining extraction mappings before actual thumbnail generation. This preliminary setup creates a structured framework that simplifies the subsequent extraction and generation processes, reducing real-time processing complexity while maintaining high situational awareness.
