Navigation Controller Dynamic Path Priority Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems do not allow drivers to change path-finding conditions, such as using toll roads, while driving without manual operation, and only offer alternative paths based on the same conditions as the initial route, failing to meet drivers' needs for real-time adjustments.
Innovation Solution
A navigation apparatus with a controller that continuously monitors the vehicle's position and changes path-finding priorities to display multiple paths based on different conditions, allowing drivers to switch to alternative routes automatically by updating path-finding conditions in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the navigation apparatus displays only one navigating path based on a single path-finding condition, then the device complexity is reduced and ease of operation is improved, but the adaptability is worsened because the driver cannot change path-finding conditions while driving
Solution Approach 1:
The navigation apparatus pre-calculates and stores multiple navigating paths based on different path-finding conditions (shortest time, shortest distance, freeway-detouring, etc.) before the driver needs them. When the driver wants to change conditions, the system already has alternative paths ready to display, eliminating the need for real-time recalculation and reducing operational complexity
Solution Approach 2:
The path-finding system is designed to handle multiple path-finding conditions simultaneously using the same hardware infrastructure. The controller can switch between different path-finding algorithms (shortest time, shortest distance, etc.) without requiring separate physical devices, achieving multi-functionality with a single system
2Ease of operation
If the navigation apparatus requires manual operation to update path-finding conditions, then the device complexity is reduced, but the ease of operation is worsened because the driver must stop the vehicle to change conditions
Solution Approach 1:
The navigation apparatus automatically detects when the vehicle has deviated from the current navigating path and autonomously updates the path-finding conditions and recalculates alternative paths without requiring driver intervention. The system monitors vehicle position continuously and self-adjusts the navigation parameters, eliminating the need for manual operation and vehicle stopping
3Adaptability or versatility
If the navigation apparatus displays multiple navigating paths based on different path-finding conditions, then the adaptability is improved, but the ease of operation is worsened because the driver must operate the apparatus to select and update paths
Solution Approach 1:
The navigation apparatus continuously monitors vehicle position through the locator and compares it with the current navigating path. When deviation is detected, the system automatically triggers an updating path-finding operation and displays new alternative paths, providing real-time feedback without requiring driver input. This closed-loop system maintains adaptability while minimizing operational burden

AI summary
A controller of a navigation terminal (navigation apparatus) is configured to find a plurality of paths from a current position of a vehicle and a destination based on a plurality of different and prioritized path-finding conditions, respectively, and causes a display to show the plurality of paths which includes a navigating path found on the basis of a top-priority path-finding condition and at least one alternative path found on the other path-finding condition(s). In response to detection of deviation of the vehicle, the priority assigned to a path-finding condition based on which a specific alternative path along which the vehicle is running is changed into a top priority, and path-finding operation is performed again for paths from the current position of the vehicle to the destination to show a new navigating path and at least one new alternative path in the display.
