Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing vehicle failure prediction systems risk distracting drivers with unnecessary notifications during non-urgent failure predictions, leading to reduced driving efficiency and safety.

Innovation Solution

A system that identifies vehicle occupants and compares them to management and repair participants, only outputting failure notifications when the occupant is a participant and the failure occurs within their usage period, ensuring safe and efficient driving.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If failure notification is provided to all vehicle users, then the management and repair participant can be informed of predicted failures, but non-participant users experience distraction and reduced driving safety

Engineering Contradiction:

Improvefailure prediction notification reliabilityVSAvoiddriver distraction

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The notification system applies different treatment rules to different user groups. Management and repair participants receive failure notifications, while non-participant users do not. This local differentiation ensures that only the appropriate audience receives notifications, eliminating driver distraction while maintaining reliable failure prediction for the right stakeholders.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The notification control device acts as an intermediary between the failure prediction system and the user interface. It receives failure prediction results, identifies the current driver's participant status, and selectively forwards or blocks notifications based on this identification. This intermediary layer prevents direct transmission of potentially distracting notifications to inappropriate users.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of information

If failure notification is provided to all vehicle users, then comprehensive failure information is delivered, but route information and traffic information provision is suppressed

Engineering Contradiction:

Improvefailure information deliveryVSAvoiddriving efficiency

Core Design Contradiction:

Loss of informationVSProductivity

Solution Approach 1:

The system applies different information delivery policies to different user groups. Management and repair participants receive both failure notifications and maintain access to route/traffic information. Non-participant users receive only route and traffic information without failure notifications. This local quality approach ensures that driving efficiency is maintained for all users while failure information is delivered to the appropriate audience.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The information delivery system is segmented into different channels and priorities. Failure prediction information is separated from navigation information, and the notification control device selectively routes these different information types to appropriate users based on their participant status, preventing information overload and maintaining driving efficiency.

Inventive Principle:

Principle #1Segmentation

3Object-affected harmful factors

If failure notification is restricted to management and repair participants only, then driver distraction is minimized, but non-participants cannot be informed of failures affecting their usage period

Engineering Contradiction:

Improvedriver distractionVSAvoidfailure information accessibility

Core Design Contradiction:

Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The notification control device serves as an intelligent intermediary that identifies the current driver's participant status and selectively transmits failure notifications. When the driver is a non-participant, notifications are blocked to prevent distraction. When the driver is a management or repair participant, notifications are forwarded. This intermediary mechanism resolves the contradiction by adapting information delivery to the specific user context.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The notification system dynamically adjusts its behavior based on the identity of the current driver. The notification control device continuously monitors user identification and changes the notification delivery state accordingly - enabled when a participant is driving, disabled when a non-participant is driving. This dynamic adaptation ensures safety while maintaining information accessibility when appropriate.

Inventive Principle:

Principle #15Dynamics

AI summary

Failure prediction information output control device has a failure prediction unit (6) predicting failure of vehicle based on vehicle signal, a failure time estimation unit (7) estimating a time when the failure of the vehicle occurs based on the predicted failure, a data base (2) storing identification information of a management and repair participant of the vehicle, an occupant detection unit (3) detecting identification information of an occupant, a judgment unit (4) judging whether the occupant is the management and repair participant, and an output control unit (9) which, when it is judged that the time when the failure of the vehicle occurs in a case where the occupant is a user who is not the management and repair participant at a time when the failure of the vehicle is predicted is out of a vehicle usage period, does not output notification information about the predicted failure to the occupant.
