Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing systems for collecting a driver's intentions, such as depressing a Like or Dislike button in a vehicle, often annoy the user by notifying them during driving or failing to notify them, leading to forgotten reasons for the action.

Innovation Solution

An information output system that recognizes user-designated information and outputs an interface for associated secondary information during the vehicle's OFF period, minimizing annoyance by timing the request for input when the user is likely to have finished driving and can recall the situation more easily.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the query or indication that the query is received is notified to a terminal used by the user during driving of the user, then the user is likely to feel annoyed

Engineering Contradiction:

Improveuser convenienceVSAvoiduser annoyance

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary action by storing the query and its reception status in advance during the ON period, and only notifies the user after the OFF period begins. This timing strategy prevents annoyance during driving while ensuring the user receives the notification when the vehicle is stationary.

Inventive Principle:

Principle #10Preliminary action

2Object-affected harmful factors

If the query or the indication that the query is received is not notified to the user, then time elapses while the user does not notice that the query is transmitted to the SNS

Engineering Contradiction:

Improveuser annoyanceVSAvoidtime delay

Core Design Contradiction:

Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The system uses periodic action by checking the vehicle's ON/OFF status transitions and notifying the user at the appropriate period boundary (after OFF period begins). This ensures timely notification without causing annoyance during the driving period.

Inventive Principle:

Principle #19Periodic action

3Object-affected harmful factors

If the query is not notified to the user during driving, then the user is likely to forget the reason for the depressing operation

Engineering Contradiction:

Improveuser annoyanceVSAvoidmemory retention

Core Design Contradiction:

Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The system performs preliminary action by storing the query reception indication and associated information in advance during the ON period, then presents this stored information to the user after the OFF period begins. This timing ensures the user receives the notification while still remembering the reason for the button press, without being annoyed during driving.

Inventive Principle:

Principle #10Preliminary action

AI summary

An information output system includes an output unit (25) configured to output information, an information recognizing unit (212) configured to recognize first information according to designation operation by a user, and an output control unit (211) configured to cause, on condition that a present OFF period of a moving body (3) is started, the output unit (25) to output, in a form recognizable by the user, an interface for requesting an input of second information that should be associated with the first information recognized after a start of a present ON period of the moving body (3) and information indicating one or both of the location and the time point.
