Solution Overview

Problem

Conventional navigation systems are inconvenient and distracting for drivers when setting waypoints, as they require multiple steps and do not notify drivers about significant route increases, potentially leading to unnecessary routing and increased costs.

Innovation Solution

A route planning apparatus and method that allows drivers to add and prioritize waypoints with a notifying message when adding a new waypoint would significantly increase the route, using a threshold value to determine if the addition is worthwhile, and generating an optimized route based on driver preferences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the navigation system automatically sets a POI as a waypoint, then the waypoint setting process becomes more convenient and faster, but the system may set unrealistic waypoints that significantly increase the route distance

Engineering Contradiction:
Improvewaypoint setting convenienceVSAvoidroute distance
Core Design Contradiction:
Ease of operationVSLength of moving object

Solution Approach 1:

The system calculates the distance increase that would result from setting a POI as a waypoint and provides feedback to the driver through a notification message. This feedback mechanism allows the driver to make an informed decision about whether to proceed with the automatic waypoint setting, thus resolving the contradiction between convenience and route optimization.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs a preliminary calculation to determine if setting a POI as a waypoint would significantly increase the route distance before actually setting the waypoint. By anticipating and preventing unrealistic waypoint settings in advance, the system avoids the problem of excessive route distance while maintaining the convenience of automatic waypoint setting.

Inventive Principle:
Principle #9Preliminary anti-action

2Reliability

If the navigation system requires multiple steps to set a waypoint manually, then the driver has full control over waypoint selection, but the process becomes time-consuming and distracting

Engineering Contradiction:
Improvedriver control over routingVSAvoidwaypoint setting time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system automatically identifies POIs along the route and presents them as waypoint options to the driver, eliminating the need for manual searching and selection. This self-service approach significantly reduces the time required for waypoint setting while maintaining driver control, as the driver simply needs to review and confirm the automatically generated options.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary actions by automatically calculating the route, identifying suitable POIs along the path, and preparing waypoint suggestions before the driver needs to make a decision. This preliminary preparation reduces the interaction time required from the driver while ensuring that the options presented are already optimized for the route.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the navigation system allows adding multiple POIs as waypoints, then the driver can customize the route according to preferences, but the total route distance may significantly increase

Engineering Contradiction:
Improveroute customizationVSAvoidtotal route distance
Core Design Contradiction:
Adaptability or versatilityVSLength of moving object

Solution Approach 1:

When the driver adds multiple POIs as waypoints, the system continuously calculates the cumulative distance increase and provides feedback through notification messages. This allows the driver to understand the impact of each additional waypoint on the total route distance and make informed decisions about route customization, balancing adaptability with distance control.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system dynamically recalculates the route and distance implications whenever the driver adds or modifies waypoints. This dynamic adjustment ensures that the driver receives up-to-date information about the total route distance, enabling flexible route customization while maintaining awareness of the distance trade-offs.

Inventive Principle:
Principle #15Dynamics

AI summary

A route planning system and method for a navigation system which allows the driver to intelligently plan the route when adding waypoints. The route planning navigation system includes a route planning processor which allows the driver to add and prioritize multiple POIs as waypoints. When one or more new waypoints are added, the driver is allowed to prioritize the waypoints if adding new waypoints does not significantly increase the cost of the route, and an optimized route is generated accordingly. In another aspect, if adding new waypoint significantly increases the cost of the route, a notifying message will be generated by the route planning processor so that the driver is able to make a decision whether to proceed to the new waypoint.
