Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If 3D maps are used for navigation, then the visual realism and spatial understanding are improved, but the processing intensity and battery consumption increase
Solution Approach 1:
The patent implements dynamic switching between 2D and 3D map views based on user interaction and navigation context. The system transitions from static 3D rendering to dynamic 2D/3D hybrid views, reducing processing intensity while maintaining visual realism when needed. This is achieved through gesture-based controls that allow users to switch between view modes, optimizing battery consumption while preserving spatial understanding capabilities.
Solution Approach 2:
The patent applies 3D rendering selectively to specific areas of the map rather than the entire map view. By rendering 3D buildings and terrain only in the foreground or areas of user interest while keeping background areas in 2D, the system maintains visual realism where needed while significantly reducing overall processing intensity and battery consumption.
2Loss of information
If 3D maps are used for navigation, then the spatial understanding is improved, but the processing speed and efficiency decrease
Solution Approach 1:
The patent segments the map rendering into multiple layers and views. The system divides the navigation display into 2D base map layers and 3D overlay layers, allowing independent rendering optimization. This segmentation enables the system to maintain spatial understanding through 3D elements while improving overall processing speed by rendering less complex 2D layers simultaneously.
Solution Approach 2:
The patent implements dynamic view switching that allows the system to transition between 2D and 3D representations based on real-time user interaction. When processing speed is critical or battery is low, the system dynamically switches to 2D views with enhanced annotations, maintaining spatial understanding while improving processing efficiency.
3Adaptability or versatility
If multiple navigation views are provided, then the user experience and adaptability are improved, but the device complexity increases
Solution Approach 1:
The patent implements a universal control interface that handles multiple navigation views (2D, 3D, hybrid) through a single set of gesture-based controls. The same touch interface mechanisms serve multiple functions: pinching to zoom, swiping to change views, tapping to select features. This multi-functionality approach provides adaptability across different view modes while minimizing the increase in device complexity by reusing the same control paradigm.
Data Source
AI summary
Some embodiments provide a navigation application. The navigation application includes an interface for receiving data describing junctures along a route from a first location on a map to a second location on the map. The data for each juncture includes a set of angles at which roads leave the juncture. The navigation application includes a juncture decoder for synthesizing, from the juncture data, instruction elements for each juncture that describe different aspects of a maneuver to be performed at the juncture. The navigation application includes an instruction generator for generating at least two different instruction sets for a maneuver by combining one or more of the instruction elements for the juncture at which the maneuver is to be performed. The navigation application includes an instruction retriever for selecting one of the different instruction sets for the maneuver according to a context in which the instruction set will be displayed.
