Solution Overview

Problem

Existing travel route presentation systems do not consider the health condition of the occupant, which may result in uncomfortable driving experiences.

Innovation Solution

A travel route presentation system that acquires user information, estimates the user's health condition, selects a suitable travel route based on this information, and presents the route to the user.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the notification system presents replenishment location based only on occupant preferences, then the system complexity is low, but the comfort of driving is insufficient

Engineering Contradiction:
Improvecomfort of drivingVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system performs preliminary estimation of the occupant's health condition based on predetermined information before presenting the replenishment location. The acquisition unit acquires predetermined information on the user, and the estimation unit estimates the health condition in advance, allowing the system to proactively suggest comfortable driving routes before the occupant experiences discomfort.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from the estimated health condition to adjust the replenishment location suggestions. The selection unit selects at least one travel route based on the estimation result of the health condition, creating a feedback loop where the presented information adapts to the occupant's actual physiological state rather than just static preferences.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If the system considers health condition information, then the comfort of driving is improved, but the information processing requirement increases

Engineering Contradiction:
Improvecomfort of drivingVSAvoidinformation processing requirement
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The system acquires predetermined information on the user beforehand and estimates the health condition in advance of presenting the replenishment location. This preliminary processing allows the system to have health condition data ready when needed, reducing the information processing burden at the moment of decision-making.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If the system selects travel routes based on health condition estimation, then the comfort of driving is improved, but the calculation complexity increases

Engineering Contradiction:
Improvecomfort of drivingVSAvoidcalculation complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The estimation unit estimates the health condition based on predetermined information before the route selection process. By having the health condition estimation completed in advance, the selection unit can directly use this estimated value to select appropriate travel routes without performing complex real-time calculations during route selection.

Inventive Principle:
Principle #10Preliminary action
