Road Surface Notification Image Display Interference Control

Solution Overview

Problem

Existing image display devices on road surfaces face challenges in effectively notifying information to targets, such as pedestrians, due to potential interference with surrounding vehicle notifications, leading to unclear or missed important safety information.

Innovation Solution

An image display device equipped with an illuminator, detector, and circuitry that analyzes and evaluates notification priority levels, controlling the display of own-vehicle notification images to avoid interference with surrounding-vehicle notifications, ensuring clear and appropriate information dissemination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the illuminator displays notification images on the road surface, then information can be notified to the surroundings, but interference with surrounding vehicle notifications occurs leading to unclear important safety information

Engineering Contradiction:

Improvenotification information clarityVSAvoidinterference between notifications

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The detector captures images of notification images displayed on the road surface by other vehicles, and the controller uses this feedback information to adjust the display timing and content of the own vehicle's notification images, preventing interference with surrounding vehicle notifications

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The controller predicts the display timing and position of surrounding vehicle notification images based on detected information, and adjusts the own vehicle's notification display in advance to avoid overlapping with higher priority notifications

Inventive Principle:

Principle #10Preliminary action

2Reliability
