Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing navigation systems primarily focus on efficiency-oriented routes, failing to provide users with the option to create courses that prioritize joy of travel and scenic experiences based on predetermined evaluation criteria.

Innovation Solution

An information processor and system that calculates course evaluation points based on a predetermined evaluation criterion, allowing users to designate and display routes that include 'stop-by' spots and 'nice-moment' places, enabling the creation of courses that emphasize travel experience and scenery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If efficiency-oriented routes are used, then travel time and distance are minimized, but joy of travel and scenic experiences are compromised

Engineering Contradiction:

Improvetravel timeVSAvoidroute type variety

Core Design Contradiction:

Loss of timeVSAdaptability or versatility

Solution Approach 1:

The navigation system dynamically adjusts route recommendations based on user preferences and evaluation criteria. Users can switch between efficiency-oriented routes and experience-oriented routes by adjusting their preferences, allowing the system to adapt the route type dynamically rather than being fixed

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the evaluation parameters used for route selection based on user input. By modifying the weightings and criteria for evaluating routes (such as prioritizing scenic views over distance), the system can generate different route types that satisfy diverse user needs

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If course evaluation points are calculated and displayed, then user selection capability is improved, but display screen complexity increases

Engineering Contradiction:

Improveroute selection capabilityVSAvoiddisplay screen complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The display screen is segmented into distinct regions: one for displaying the route course and another for displaying evaluation points. This segmentation allows both pieces of information to be presented clearly without overwhelming the user, maintaining ease of operation while managing display complexity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Evaluation points serve as an intermediary element that bridges the route course display and user selection. Instead of directly complicating the interface, the evaluation points act as a mediating layer that provides structured information to help users make selections without adding excessive complexity

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An information processor includes a course evaluation unit, a display controller, and a guidance course setting unit. The course evaluation unit calculates course evaluation points based on a predetermined evaluation criterion, with respect to a course serially coupled and created between a starting point, one or more via-points, and a destination point. The display controller provides display of the course and an indicator of the course evaluation points on the same screen. The guidance course setting unit sets the course displayed on the screen as a course for route guidance on the basis of an operation by a user.
