Vehicle Display Device with Recessed Side Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-up display devices for vehicles compromise vehicle interior design as the increasing width of display light irradiation requires larger openings, making the opening side surfaces more noticeable and detracting from the interior aesthetics.
Innovation Solution
A display device for vehicles that includes an irradiation unit projecting light onto a reflection member through an opening in the instrument panel, with a display section on the opening side surface, extending from the opening peripheral part, and a hood covering the display section, allowing for a recessed groove configuration to minimize visibility of the opening side surface and enhance information display without obstructing the driver's line of sight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the width of irradiation of display light is increased to present more information to the driver, then the amount of information displayed is improved, but the opening size becomes larger which makes the opening side surface more noticeable and deteriorates vehicle interior design
Solution Approach 1:
The patent places the display section on the opening side surface (a vertical/different dimensional plane) rather than expanding the horizontal opening width. This allows information to be displayed in a new spatial dimension, increasing information capacity without enlarging the opening area that would affect interior design aesthetics.
Solution Approach 2:
The patent divides the information display function into two separate sections: the irradiation unit for head-up display and the display section on the opening side surface. This segmentation allows each component to serve its specific purpose without compromising the other, enabling more information to be displayed while maintaining a clean opening design.
2Loss of information
If a display section is added on the opening side surface to display more information, then the amount of information is improved, but the device complexity increases
Solution Approach 1:
The opening side surface serves multiple functions: it acts as a structural component of the instrument panel, provides a mounting surface for the display section, and serves as a visible area for information display. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.
Solution Approach 2:
The patent merges the display section with the opening side surface structure, integrating the display function into the existing instrument panel architecture rather than adding a completely separate system. This integration approach minimizes the increase in device complexity by utilizing existing structural elements.
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
Enables the display of a larger amount of information to the driver while maintaining a superior vehicle interior design, with the display section providing clear and detailed information, complementing the head-up display by projecting essential information and preventing light reflection issues.
Implementation Method 1
Display light emitted by the irradiation unit is projected onto a reflection member (e.g., a windshield or a combiner), whereby the driver can view a virtual image (information displayed by the display light) appearing in a vehicle forward direction from the reflection member

AI summary
A display device for a vehicle includes an irradiation unit that projects, through an opening provided to an instrument panel, display light onto a windshield located above the opening; and a display panel that is disposed on an opening side surface extending from an opening peripheral part toward a lower part of the instrument panel and that displays information to a driver.
