Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing navigation systems primarily focus on efficiency-oriented route creation, failing to provide routes that prioritize joy of travel and scenic experiences, which are desirable for non-efficiency-oriented travel paths.

Innovation Solution

An information processor and method that set a starting point, via-points, and a destination point, calculating course evaluation points based on predetermined criteria such as joy of travel and scenic appeal, to create and guide users through routes that emphasize experience over efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If navigation systems prioritize efficiency-oriented route creation, then travel time and distance are reduced, but travel experience and scenic appeal deteriorate

Engineering Contradiction:

Improvetravel timeVSAvoidtravel experience

Core Design Contradiction:

Loss of timeVSEase of operation

Solution Approach 1:

The system changes the evaluation parameters from purely efficiency-based (time, distance) to include experience-based parameters (scenic appeal, joy of travel). The course evaluation unit calculates multiple types of evaluation points including first evaluation points for efficiency and second evaluation points for experience, then combines them to determine the final proposed course.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If navigation systems focus on shortest path calculation, then productivity is improved, but route satisfaction and scenic value worsen

Engineering Contradiction:

Improveroute calculation efficiencyVSAvoidroute satisfaction

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The route evaluation process is segmented into multiple independent evaluation components. The course evaluation unit separately calculates first evaluation points (efficiency) and second evaluation points (experience), allowing each aspect to be optimized independently before combining them for the final route determination.

Inventive Principle:

Principle #1Segmentation

3Reliability

If navigation systems use traditional route guidance, then reliability is maintained, but adaptability to user preferences deteriorates

Engineering Contradiction:

Improveroute guidance reliabilityVSAvoiduser preference adaptability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts the route selection criteria based on user preferences. The setting unit allows users to specify their preferred balance between efficiency and experience, and the course setting unit dynamically selects the proposed course based on both the evaluation points and user preferences, making the system adaptable while maintaining reliability.

Inventive Principle:

Principle #15Dynamics

AI summary

An information processor includes a setting unit, a course creation unit, a course evaluation unit, and a course setting unit. The setting unit sets a starting point, one or more via-points, and a destination point. The course creation unit creates a course serially coupled between the starting point, the one or more via-points, and the destination point set by the setting unit. The course evaluation unit calculates course evaluation points based on a predetermined evaluation criterion, with respect to the course created by the course creation unit. The course setting unit sets the course as a proposed course for route guidance, on the basis of the course evaluation points.
