Road Projection Control for Clear Vehicle Turn Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular drawing devices on road surfaces become confusing when the turn indicator lever is operated at the time of starting travel, as both the turn indication and start-traveling displays are displayed simultaneously, leading to unclear visual cues for direction changes.
Innovation Solution
A vehicular drawing device with a processor that prioritizes the turn indication display over the start-traveling display when the turn indicator switch is on during starting travel, allowing for the cancellation or reduction of the start-traveling display's conspicuousness through adjustments in brightness, saturation, hue, and blinking, and directional changes based on the turn indicator switch's direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If both turn indication display and start-traveling display are displayed simultaneously when turn indicator is operated during starting travel, then both information types are provided, but the display becomes confusing and visual recognition is reduced
Solution Approach 1:
The patent applies parameter changes by modifying the display parameters (brightness, saturation, hue, blinking) of the start-traveling display to create an inconspicuous display when turn indication is simultaneously required. This resolves the contradiction by changing the visual parameters of one display to prevent confusion while maintaining both information types.
Solution Approach 2:
The patent applies local quality by making the start-traveling display inconspicuous (reduced brightness, saturation, or blinking) while keeping the turn indication display conspicuous. This creates different visual qualities for different display elements, allowing both to coexist without confusion.
2Illumination intensity
If the start-traveling display is displayed with high conspicuousness, then it is easily recognized, but it creates confusion when turn indication is also needed
Solution Approach 1:
The patent dynamically changes the illumination parameters (brightness, saturation, blinking) of the start-traveling display based on whether turn indication is simultaneously required. When turn indication is active, the start-traveling display parameters are adjusted to be inconspicuous; otherwise, they remain conspicuous for easy recognition.

AI summary
A vehicular drawing device is installed in the vehicle and draws, using light, an indication display with a predetermined shape on a road surface in a direction of travel of the vehicle. The indication display includes a start-traveling display drawn at a time of starting traveling and a turn indication display drawn when a turn indicator switch is turned on and the direction of travel is changed. The turn indication display is drawn with priority over the start-traveling display when the turn indicator switch is on at the time of starting traveling.
