Smart Navigation Device Toll Road Exclusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation devices fail to provide a route planning function that allows users to avoid specific toll roads, especially when freeways are under construction or when users prefer not to drive on certain freeways, limiting user flexibility and cost savings.
Innovation Solution
A smart navigation device with a storage unit, positioning module, and navigation module that generates a cost-saving route by excluding selected toll roads from the navigation route, using map information and user input to replan the route, allowing users to choose toll-free alternatives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the fastest route planning function is selected, then the navigation time is reduced, but the user is forced to use toll roads which increases cost
Solution Approach 1:
The navigation system dynamically adjusts route planning based on user-selected preferences. When a user excludes specific toll roads, the system dynamically recalculates and provides alternative routes, transforming the static route planning into a dynamic, adaptive process that balances speed and cost based on real-time user input.
Solution Approach 2:
The system changes the routing parameters by allowing users to exclude specific toll roads from consideration. This parameter modification enables the navigation algorithm to optimize routes based on updated constraints, providing alternatives that balance navigation speed with toll cost reduction.
2Length of moving object
If the shortest route planning function is selected, then the distance is reduced, but the navigation route may include roads under construction or unwanted by the user
Solution Approach 1:
The system transforms static shortest-route planning into a dynamic process where users can actively exclude specific roads or toll roads they wish to avoid. The navigation algorithm continuously adapts the route based on user preferences, maintaining shortest-distance optimization while incorporating real-time user constraints.
Solution Approach 2:
Users modify routing parameters by selecting specific roads or toll roads to exclude. This changes the optimization criteria from purely distance-based to a multi-parameter optimization that considers both distance and user preferences, enabling flexible route planning that avoids construction zones or unwanted areas.
3Device complexity
If traditional route planning functions are used, then the system complexity is low, but the user cannot avoid specific toll roads or customize the route
Solution Approach 1:
The navigation system segments the route planning process into distinct phases: initial route calculation, user preference input, and iterative optimization. This segmentation allows the system to maintain relatively simple core functionality while adding customization layers that enable users to exclude specific toll roads without fundamentally complicating the entire system architecture.
Solution Approach 2:
The system incorporates feedback mechanisms where user selections about toll road exclusion are processed and fed back into the routing algorithm. This feedback loop allows the system to learn from user preferences and automatically adjust future route recommendations, providing customization without requiring complex manual configuration.

AI summary
A smart navigation device includes a storage unit for storing map information therein, a positioning module for determining a current location, and a navigation module for generating a navigation route based on a target location, the current location, and the map information. When the navigation route includes a plurality of toll roads and one of which is selected to be excluded from the navigation route, the navigation module re-plans to generate a cost-saving navigation route. Therefore, a user is allowed to select and avoid any toll road on the navigation route. A smart navigation method applicable to vehicle navigation is also disclosed.
