Navigation Apparatus with Removable Media for Dynamic Destination Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of rental vehicles face a high burden when setting navigation paths, especially when destinations change or unforeseen circumstances arise, as existing navigation systems require manual operation and do not easily accommodate deviations from pre-set paths.
Innovation Solution
A navigation apparatus with a removably installed recording medium that displays candidate site data, allowing users to select an end point from pre-designated locations, including related locations such as restaurants, hospitals, or gas stations, which are transmitted to the navigation system via a server apparatus, reducing the need for manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a navigation apparatus is installed in a rental car with pre-set guidance paths, then the initial setup burden is reduced, but the system becomes meaningless when destinations change or users need to deviate from pre-set paths
Solution Approach 1:
The system performs preliminary actions by pre-fetching and storing candidate site data (facility names, addresses, coordinates) in the navigation apparatus before the user arrives. This allows the user to quickly select from pre-prepared options rather than searching from scratch, combining advance preparation with flexible user choice.
Solution Approach 2:
The system enables self-service by automatically providing candidate site data without requiring manual input from the user. The navigation apparatus independently manages the candidate sites and presents them for selection, reducing the operational burden on users while maintaining adaptability.
2Ease of operation
If the rental car vendor pre-sets the guidance path in the navigation apparatus, then operation burden is reduced, but the system cannot accommodate changes in destination or unforeseen circumstances
Solution Approach 1:
The system transitions from a static pre-set path to a dynamic selection mechanism. Users can dynamically choose from multiple candidate sites presented on screen, and the system automatically updates the guidance path based on user selection, enabling adaptation to changing needs while maintaining ease of operation.
Solution Approach 2:
The system incorporates feedback by monitoring user selections from candidate sites and automatically adjusting the guidance path accordingly. This closed-loop mechanism allows the system to adapt to user decisions in real-time without requiring complex manual reconfiguration.
3Adaptability or versatility
If a user manually operates the navigation apparatus to set destinations, then flexibility to change destinations is maintained, but the operation burden increases significantly for inexperienced users
Solution Approach 1:
The system performs preliminary actions by pre-fetching and organizing candidate site data before user interaction. This preparation work is done automatically, presenting users with ready-to-select options rather than requiring them to perform complex search and input operations, thereby reducing operational burden while maintaining flexibility.
4Speed
If the navigation apparatus stores detailed facility data locally, then quick access to candidate sites is enabled, but the device complexity and memory requirements increase
Solution Approach 1:
The system extracts only the essential candidate site data (names, addresses, coordinates) needed for quick selection from the complete facility database. This selective extraction reduces the amount of data stored locally while maintaining quick access capabilities, balancing speed requirements with device complexity constraints.

AI summary
A navigation apparatus of the invention includes a display portion that displays a guidance screen and a removably installed recording medium, the navigation apparatus being provided in a vehicle and guiding the vehicle along a guidance path. When candidate site data created in an external apparatus has been stored on the storage medium, a screen for selectively setting the end point of the guidance path based on the candidate site data is displayed in the display portion, and when setting the end point, a guidance path that arrives at the end point is calculated. The candidate site data includes information related to one or a plurality of locations that have been designated in advance by a user of the navigation apparatus, and the end point is selected from the one or plurality of locations.
