Vehicle Navigation Guide Point Setting via Proposed Action Selection

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional on-vehicle navigation systems fail to provide an optimal guide point corresponding to the user's proposed action at a destination or way point, requiring users to manually modify the guide point, which is inconvenient, especially when the desired location within a large establishment, such as a shopping mall, is not initially guided to.

Innovation Solution

The system includes a display means, input means, and storage means to provide a list of proposed actions associated with each destination or way point, allowing users to select a proposed action, which the control means uses to search and set the corresponding guide point, thereby optimizing the guide point based on the user's purpose.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the navigation system guides to the representative location of a destination (e.g., front entrance of shopping mall), then the route search function can be performed, but the guide point does not correspond to the user's proposed action, requiring manual modification

Engineering Contradiction:

Improveease of setting guide pointVSAvoidprecision of guide point location

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The system pre-stores multiple candidate guide points within each destination along with proposed actions in a database. When a user selects a destination and a proposed action, the system automatically retrieves and sets the corresponding guide point without requiring manual modification, thus performing the precise location setting action in advance

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The navigation system automatically matches the user's selected proposed action with the corresponding guide point from stored data, and autonomously sets the guide point without requiring manual intervention. The system serves itself by automatically adjusting the guide point based on the proposed action selection

Inventive Principle:

Principle #25Self-service

2Measurement precision

If the system provides automatic guide point setting based on proposed action, then the precision of guide point location improves, but the device complexity increases due to additional storage and processing requirements

Engineering Contradiction:

Improveprecision of guide point locationVSAvoidcomplexity of storage and control system

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The database stores multiple guide points and proposed actions for each destination in a unified structure, allowing the same storage system to serve multiple destinations and multiple proposed actions simultaneously. This multi-functional approach avoids the need for separate storage systems for each destination-action combination

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

All guide points and proposed actions are pre-stored in the database during system setup or data preparation phase. This preliminary action eliminates the need for complex real-time calculations or manual interventions during actual navigation, reducing the processing burden on the control unit

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If manual modification of guide point is required, then the system can adapt to specific user needs, but the time required for setting increases

Engineering Contradiction:

Improveadaptability to user needsVSAvoidtime for setting guide point

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system pre-preares multiple guide points corresponding to different proposed actions for each destination. When the user selects a proposed action, the matching guide point is immediately retrieved and set, eliminating the time-consuming manual modification process while maintaining adaptability to specific user needs

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system displays the list of proposed actions to the user, who selects the desired action. The system then provides feedback by automatically setting the corresponding guide point and confirming the selection, creating a closed-loop interaction that adapts to user needs without manual guide point modification

Inventive Principle:

Principle #23Feedback

AI summary

The invention provides an on-vehicle navigation system, route guide method, and computer-readable recording medium capable of setting an optimum guide point corresponding to proposed actions set as destinations or way points, and performing route guidance based on the setting. The on-vehicle navigation system includes a function of searching for a guide route leading to a set destination or the like and displaying the searched guide route on a screen of a display to guide the vehicle. The route guide method includes: registering information organized in a list form in a storage means, in which each of the places prepared as candidates for destinations or the like is associated in advance with proposed actions at the place; when a destination or the like is selected, extracting the information on the proposed actions at the place to display it in a list form on the screen of the display; when any of the proposed actions is selected, referring to a map database to search for a guide point corresponding to the selected proposed action; and setting the searched guide point as the destination or the like.
