Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Navigation devices often provide low recognition value for complex route situations, leading to user confusion and increased safety risks, especially during complex maneuvers, as they require users to constantly compare real traffic conditions with schematic representations.
Innovation Solution
A navigation device and method that dynamically switch between 2D and 3D visualization modes based on upcoming route transitions, using overlaying visualization layers with real-time data from a road network database to provide a high recognition value for users, including photorealistic representations and relevant signage, reducing the need for static image storage and improving user attention on the road.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If schematic representations of road network and route are used, then device complexity is reduced, but recognition value for actual road conditions deteriorates
Solution Approach 1:
The patent transitions from two-dimensional schematic map representations to three-dimensional photorealistic images that replicate the actual visual appearance of road intersections and transitions. This dimensional change allows the display to show realistic building silhouettes, road layouts, and environmental features that match the driver's real-world view, significantly improving recognition value while maintaining manageable device complexity through software-based rendering.
Solution Approach 2:
The patent creates photorealistic copies of actual road intersection views by rendering three-dimensional images that replicate the visual characteristics of the real environment. These copied visual representations include accurate building silhouettes, road geometries, and environmental features that mirror the actual scene the driver will encounter, enabling immediate visual comparison between the display and reality without requiring complex hardware modifications.
2Loss of information
If photorealistic three-dimensional images are generated and stored for every intersection, then recognition value is improved, but storage requirements and device complexity increase significantly
Solution Approach 1:
The patent implements dynamic generation of photorealistic three-dimensional images on-demand based on the vehicle's current position and upcoming route transitions. Rather than storing static pre-rendered images for every possible intersection, the system dynamically creates appropriate visual representations using stored geometric and environmental data, significantly reducing storage requirements while maintaining high recognition value for actual road conditions.
Solution Approach 2:
The patent performs preliminary preparation by storing essential geometric data, building silhouettes, and environmental features in the navigation device. This preliminary action enables the system to quickly generate photorealistic three-dimensional images when needed, rather than requiring extensive pre-computation and storage of complete images for all possible scenarios. The essential visual elements are prepared in advance in a compressed form that can be rapidly rendered when the vehicle approaches an intersection.
3Reliability
If the display provides detailed three-dimensional views of intersections, then user recognition and safety are improved, but user attention is diverted from the actual road
Solution Approach 1:
The patent applies photorealistic three-dimensional visualization selectively only at specific locations where the vehicle is approaching intersections or complex route transitions. The display maintains its conventional schematic map representation for all other segments of the journey. This localized application of enhanced visualization provides critical visual information exactly where needed for safety while minimizing overall distraction by keeping the display familiar and simple during normal driving segments.
Solution Approach 2:
The patent implements periodic switching between conventional schematic display mode and photorealistic three-dimensional visualization mode based on the vehicle's proximity to intersections and route transitions. The system automatically transitions to enhanced visualization temporarily when approaching complex road features, then returns to the standard display mode afterward. This periodic alternation ensures that detailed visual information is provided only during critical moments when it most enhances safety and recognition, while minimizing overall driver distraction during routine driving.

AI summary
The device has a display unit visualizing an identified routing. The device is arranged such that automatic exchange is carried out between two operating modes when existence of correction, which is required for tracing the identified routing, of actual direction of a transportation unit through a road junction or a road intersection. The transportation unit is limited by transition of the routing from a path to another path. One of the operating modes causes visualization of the transition at the display unit by partial dynamic interaction of visualizing layers. An independent claim is also included for a method for operating a device for identifying and displaying of a routing for a transportation unit.
