Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing in-vehicle display systems cannot allow users to select registration locations for displaying captured images when the vehicle engine is off or after exiting the vehicle, limiting the ability to register preferred display locations in a safe and relaxed environment.

Innovation Solution

A display location registration method that stores display history information, including position and display mode data, on a user terminal, enabling users to select and register preferred display locations using the terminal device when the vehicle engine is off or after exiting, with the system updating the server to automatically display images at these locations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the registration location is selected using the in-vehicle display device when the vehicle engine is turned on, then the registration can be completed within the vehicle operation context, but the user cannot safely select registration locations when the vehicle engine is turned off or after exiting the vehicle

Engineering Contradiction:

Improveability to register display locationVSAvoidsafety of registration operation

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent introduces a user terminal (smartphone, tablet, or PC) as an intermediary device between the user and the vehicle display system. The user terminal receives display history information from the vehicle, allows the user to select registration locations in a safe environment outside the vehicle, and transmits the selected information back to the vehicle system. This mediator enables registration operations when the vehicle engine is off, eliminating the safety concerns of in-vehicle operations while maintaining system functionality.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of information

If the registration location is selected only when the vehicle engine is turned on, then the system can utilize real-time vehicle data, but the user loses the ability to review and select candidate registration locations in a relaxed environment

Engineering Contradiction:

Improveaccess to display history informationVSAvoidconvenience of location selection

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The system performs preliminary actions by storing display history information (including position information and display modes) in advance on the user terminal before the user needs to make selections. The user terminal receives and stores this information when the vehicle is operating, then presents it to the user for review and selection when the user is in a relaxed environment outside the vehicle. This preliminary data preparation enables informed decision-making without time pressure or safety constraints.

Inventive Principle:

AI summary

A server (40) stores, in a storage device (43), display history information including a position information history of a display location at which an in-vehicle device (20) displays a captured image using an in-vehicle camera (23) on the display unit (26). The server (40) outputs the display history information to a terminal device (50), and stores in the storage device (43), the position information of the display location selected by a user using a terminal device (50), as position information of a registration location at which the captured image is automatically displayed on the display unit (26).
