Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle navigation technologies focus primarily on the vehicle being driven and lack effective obstacle detection and warning, leading to poor navigation effects and safety during vehicle travel.
Innovation Solution
A vehicle navigation method and apparatus that displays a navigation interface with a virtual map, a vehicle identification object, and an obstacle identification object, setting a warning sign display region when an obstacle enters an early warning region, indicating distance and directional relationships to control the vehicle's travel status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional vehicle navigation technology is used, then the navigation interface can display basic road and vehicle information, but it cannot effectively detect and warn about obstacles, leading to poor safety during vehicle travel
Solution Approach 1:
The navigation interface is segmented into multiple functional display regions: a first display region showing the virtual map and vehicle icon, a second display region showing obstacle icons with warning signs, and a third display region showing detailed obstacle information. This segmentation allows simultaneous presentation of navigation information and obstacle warning information without mutual interference, resolving the contradiction between maintaining basic navigation functionality and adding comprehensive obstacle detection capabilities.
Solution Approach 2:
The patent transitions from traditional two-dimensional map display to a multi-dimensional information presentation system. It adds spatial dimensions through multiple display regions arranged in specific spatial relationships, and informational dimensions through layered warning signs (different colors indicating different risk levels) and detailed obstacle attributes. This dimensional expansion enables comprehensive obstacle information display while preserving navigation functionality.
2Reliability
If obstacle detection and warning information is added to the navigation interface, then safety during vehicle travel is improved, but the device complexity increases due to multiple display regions and warning mechanisms
Solution Approach 1:
The navigation interface is designed as a multi-functional integrated system that simultaneously performs navigation guidance and obstacle detection/warning functions. The same display device presents both the virtual map for navigation and the obstacle information with warning signs for safety monitoring. This multi-functionality approach avoids the need for separate dedicated obstacle detection displays, thereby controlling device complexity while improving safety.
Solution Approach 2:
Different regions of the display interface are assigned specific functional qualities: the first display region provides the navigation context with virtual map and vehicle position, the second display region provides obstacle detection warnings with visual alerts, and the third display region provides detailed obstacle information. Each region has optimized display characteristics for its specific function, creating a coherent whole that manages complexity through functional specialization.
3Loss of information
If detailed obstacle information is displayed in real-time, then the navigation effectiveness is improved, but the loss of time for processing and displaying information increases
Solution Approach 1:
The system pre-processes and categorizes obstacle information as it is detected, organizing data into structured formats ready for immediate display. Obstacle attributes such as type, position, distance, and risk level are pre-computed and stored in an optimized structure. When an obstacle is detected, the information is already prepared for rapid presentation across the three display regions, minimizing the time required for information processing and display while maintaining completeness.
