In-Vehicle Navigation Route Guidance with User Preference Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current in-vehicle navigation systems provide limited route guidance options that do not adequately meet user preferences, such as avoiding specific geographical features or personal points of interest, leading to inadequate route selection.
Innovation Solution
An in-vehicle navigation system that allows users to select advanced route guidance preferences, including options to avoid bridges, tunnels, mountain passes, deserts, international crossings, and personal points of interest, using a modular architecture with user input and geographic database integration to provide multiple route options based on these preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the NAV system provides only basic route options (shortest length, shortest time, fuel efficient), then the system complexity remains low and ease of operation is maintained, but the route selection capability is insufficient and does not meet diverse user preferences
Solution Approach 1:
The patent segments route guidance into multiple independent preference categories (avoid bridges, avoid tunnels, avoid mountain passes, avoid deserts, allow international crossings, show personal POIs). Each category can be independently selected and configured, allowing the system to provide comprehensive route options without overwhelming complexity. Users can choose only the preferences relevant to their needs.
Solution Approach 2:
The system dynamically adjusts route options based on user-selected preferences. The route guidance is not static but adapts in real-time according to the combination of preferences chosen by the user, enabling flexible and personalized route selection while maintaining a manageable system structure.
2Adaptability or versatility
If the NAV system integrates multiple on-board vehicle systems (music system, telephone system, climate control), then the system functionality and user convenience are improved, but the system complexity and integration requirements increase
Solution Approach 1:
The NAV system is designed as a multi-functional platform that integrates route guidance with various on-board vehicle systems (music system, telephone system, climate control). This universal approach allows a single system to perform multiple functions, improving versatility while managing integration through a unified architecture rather than separate dedicated systems.

AI summary
A navigation system (NAV system) may provide a variety of information and may be integrated with a variety of on-board vehicle systems or features. The NAV system may provide various route guidance options between a present location and a desired destination. The route guidance options may be based on a high level of user preferences. The high level of user preferences may be selected by the user in advance or at the time of requesting route guidance. The NAV system may provide various route options based on key geographical features along the route. The NAV system may provide various route options based on personal points of interest. The NAV system may provide various route options based on a user's route habits or frequency.
