Navigation Schematic Diagram for Destination Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation systems fail to assist users in recognizing their destination when streets or lanes are uniformly arranged and narrow, as they terminate navigation processes without providing clear direction to the destination.
Innovation Solution
A navigation method and system that generates a position schematic diagram displaying the destination and current device position, along with landmarks, when a predefined navigation condition is met, such as reaching a certain proximity to the destination, to aid in destination recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If navigation software terminates the navigation process when streets and lanes are uniformly arranged and narrow, then the navigation system operates within design limitations, but users cannot clearly recognize the correct location of their destination
Solution Approach 1:
The patent introduces a schematic diagram view that transforms the traditional two-dimensional map navigation into a simplified dimensional representation showing only critical elements (destination, current position, intermediate positions). This dimensional simplification resolves the contradiction by providing clear directional information without being overwhelmed by detailed street layouts, enabling users to recognize their destination even in uniformly arranged narrow streets.
Solution Approach 2:
The navigation information is segmented into critical components only (destination, current position, intermediate positions) rather than displaying complete map details. This segmentation principle resolves the contradiction by filtering out unnecessary information that causes confusion in uniform street patterns while retaining essential directional cues for destination recognition.
2Loss of information
If conventional navigation systems display detailed map information, then comprehensive navigation data is provided, but users cannot clearly identify their destination in uniformly arranged narrow streets
Solution Approach 1:
The patent extracts only the essential navigation elements (destination, current position, intermediate positions) from the complete map information and displays them in a simplified schematic diagram. This extraction resolves the contradiction by removing excessive detailed information that obscures destination identification in uniform street patterns while preserving the critical navigation data needed for guidance.
Solution Approach 2:
The schematic diagram applies local quality by differentiating the display of critical positions (destination, current position, intermediate positions) from other map elements. These key positions are highlighted with distinct visual characteristics in the schematic view, enabling users to quickly identify their location and destination without being confused by uniform street patterns.

AI summary
Navigation methods and systems are provided. First, an electronic device generates a route planning result according to at least a destination, and performs a navigation process according to the route planning result. It is determined whether at least one navigation condition has occurred. When the navigation condition has occurred, a position schematic diagram is displayed, wherein the position schematic diagram comprises the destination and a current position of the electronic device.
