Vehicle Display Moving Light Guide for Intuitive Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited space in vehicles restricts the size and installation location of display devices, making it difficult for drivers to intuitively understand instructions, especially when multiple operations need to be performed, as the display and operating elements are separated.
Innovation Solution
A vehicle display device that incorporates a moving display element and interior lighting system, where the lighting device illuminates the passenger compartment to create a moving light effect from the display element, guiding the driver to the necessary operating parts, such as the steering wheel, by moving light from the display to the operating area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display is installed at a distance from the steering wheel due to space limitations, then the display can be installed in the vehicle, but the driver cannot intuitively understand what is to be operated
Solution Approach 1:
A light guide device is introduced as an intermediary between the display and the steering wheel. The light guide device includes a light source at the display location and a light guide member that transmits light to the steering wheel area, creating a visual connection that bridges the spatial gap and guides the driver's attention to the correct operating position
Solution Approach 2:
The solution extends the information transmission from the two-dimensional display screen into the three-dimensional space by using light as a visual connector. The light guide member creates a spatial bridge that projects visual information from the display location to the steering wheel location, adding a dimensional aspect to the information transmission path
2Loss of information
If multiple operations are shown on the display, then comprehensive information is provided, but it becomes difficult to determine what is to be operated
Solution Approach 1:
The light guide device provides localized visual guidance by directing light specifically to the area around the steering wheel when a particular operation is required. This creates a focused attention guide that highlights the relevant operating position among multiple possible operations, allowing the driver to identify the current required operation through localized visual cues
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables drivers to intuitively recognize the required operating parts, even when the display is distant, by visually linking the display information with the necessary vehicle controls through a moving light effect, enhancing understanding and usability.
Implementation Method 1
the interior lighting device includes a light emitting device embedded at the interior of the vehicle and emitting light on its own
Implementation Method 2
the interior lighting device includes a light beam device beaming light on an inside surface at the interior of the vehicle

AI summary
A display device of a vehicle includes: a display provided inside of the vehicle; an interior lighting device lighting up an inside surface of a passenger compartment of the vehicle at an outside of the display; and a control device controlling the display and the interior lighting device. The control device is configured so that when a condition for moving display stands, the display is made to show a moving display element moving toward an outer circumference of the display, and so that when the moving display element reaches the outer circumference of the display, the interior lighting device lights up an inside surface of a passenger compartment of the vehicle so that a light part lit by the interior lighting device appears to move successively from the moving display element.
