Navigation Interface Dynamic Route Segmentation for Driver Safety

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current navigation systems display the entire route to a user, making it inconvenient and unsafe for drivers to view specific, non-traveled segments of the route, as they require manual operation to enlarge the map and focus on relevant information.

Innovation Solution

A method and system for a mobile terminal that calculates and displays only the remaining non-traveled navigation route and key points within a navigation interface, automatically updating the map view to prioritize relevant information, reducing the need for manual operations and enhancing safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the entire route is displayed to the user, then the user can see the full navigation path, but the user cannot clearly view specific non-traveled segments without manual operation

Engineering Contradiction:

Improvevisibility of non-traveled route segmentsVSAvoidmanual operation requirement

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent extracts and displays only the relevant portion of the route (non-traveled segments) separately from the entire route. The system identifies key points along the navigation path and displays the remaining route segments between these key points, allowing users to focus on upcoming navigation information without manually zooming or panning the map.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The navigation route is segmented into multiple sections based on key points (such as intersections, turns, or significant landmarks). Each segment represents a portion of the route from the current location to the next key point, making it easier for users to process and understand upcoming navigation instructions without being overwhelmed by the entire route at once.

Inventive Principle:

Principle #1Segmentation

2Measurement precision

If the map is enlarged to view specific road segments, then the user can see key points clearly, but the user loses overview of the entire route

Engineering Contradiction:

Improveclarity of key points displayVSAvoidoverview of entire route

Core Design Contradiction:

Measurement precisionVSLoss of information

Solution Approach 1:

The patent applies different display qualities to different parts of the route. Key points and upcoming route segments are displayed with higher clarity and detail, while previously traveled segments are shown with reduced detail or in a simplified manner. This allows the map to provide both local detail (for upcoming maneuvers) and global context (overall route progress) simultaneously.

Inventive Principle:

Principle #3Local quality

3Loss of time

If the traveled road occupies most of the field of view, then the user can see progress, but the user cannot see remaining route information clearly

Engineering Contradiction:

Improvenavigation progress trackingVSAvoidremaining route visibility

Core Design Contradiction:

Loss of timeVSLoss of information

Solution Approach 1:

Instead of displaying the route from start to end in chronological order, the patent inverts the display priority to show the remaining route segments (from current location to destination) more prominently. The traveled portion is displayed in a condensed or simplified format, while the upcoming route segments are shown with greater detail, allowing users to focus on future navigation needs rather than past progress.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A navigation system may obtain a current location of the mobile terminal in a navigation session. The navigation system may determine a remaining navigation route based on the current location and a navigation end-point. The navigation system may obtain respective locations of key points in the remaining navigation route. The navigation system may obtain a map representative of a geographic area comprising the respective locations of the key points of the navigation route. The navigation system may display, in a navigation interface, the map. The navigation system may display the remaining navigation route and the key points on the displayed map.
