Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If bitmap maps are used for displaying online user distribution, then the implementation is simple, but map zooming in arbitrary expansion cannot be implemented and precision is limited
Solution Approach 1:
The patent segments the map into multiple levels of detail (LOD), dividing the map into different zoom levels where each level contains data at an appropriate precision. This allows the system to provide high precision when zoomed in while maintaining simple implementation through pre-computed map tiles at various resolutions.
Solution Approach 2:
The patent adds a dimensional aspect by implementing arbitrary zooming capabilities that allow users to navigate through different scales of the map. This transforms the static bitmap limitation into a dynamic multi-scale representation, enabling both simple implementation through tile-based rendering and high precision through progressive detail revelation.
2Ease of manufacture
If bitmap maps are used for displaying online user distribution, then the implementation is simple, but arbitrary zooming capabilities are restricted
Solution Approach 1:
The patent transforms the static bitmap map into a dynamic system that can adapt to user zooming actions. By implementing a tile-based map system with multiple levels of detail, the map can dynamically load and display appropriate resolution tiles based on the current zoom level, providing arbitrary zooming capability while maintaining implementation simplicity through modular tile rendering.
3Ease of operation
If projection maps with known algorithms are used, then display can be performed, but maps in real-time cannot be provided and precision is limited
Solution Approach 1:
The patent applies preliminary action by pre-computing and storing map data at multiple levels of detail before runtime. Map tiles are pre-rendered at various zoom levels and stored in a cache structure, allowing the system to quickly retrieve and display appropriate tiles in real-time without performing complex projection calculations during user interaction, thus enabling both display capability and real-time performance.
4Ease of operation
If existing map systems are used, then basic display is achieved, but interactive features are limited
Solution Approach 1:
The patent implements universality by designing a map system that serves multiple functions beyond basic display. The tile-based architecture with arbitrary zooming capability enables the map to function as a versatile interactive platform that can handle display, navigation, data overlay, and region selection operations, making it adaptable to various interactive features while maintaining ease of operation through a unified interface.
