Retractable Vehicle Display With Proportional Visible Display Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display devices require changing display units based on the amount of information to be displayed, which is inefficient and inconvenient.
Innovation Solution
A display device for vehicles that includes a display unit, a display control unit, a drive unit, and a drive control unit, allowing the display area and exposed area of the display surface to be proportionally adjusted without changing the display unit, thereby accommodating varying amounts of information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display units with different display surface sizes are installed to accommodate varying information amounts, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The display unit is made movable relative to the interior member, allowing dynamic adjustment of the exposed display surface area. The drive unit enables the display unit to move between retracted and extended positions, dynamically adapting the visible display area to match the information display requirements without needing multiple fixed display units of different sizes.
Solution Approach 2:
A single display unit serves multiple functions by adjusting its exposed area rather than requiring separate display units for different information amounts. The same display unit can display small amounts of information when retracted and large amounts when extended, making it a universal solution that replaces multiple specialized display units.
2Quantity of substance
If the display area is increased to show more information, then the information display capability is improved, but the visible display surface area becomes excessively large
Solution Approach 1:
The system dynamically adjusts the exposed display surface area to match the information display requirements. When more information needs to be displayed, the drive unit extends the display unit, increasing both the display area and visible surface area proportionally. This ensures the visible area never exceeds what is needed for the current information display task.
3Adaptability or versatility
If the display unit is made movable to adjust exposed area, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
A drive unit is introduced to enable dynamic movement of the display unit relative to the interior member. This mechanical dynamic system allows the exposed display area to be adjusted on demand, providing adaptability while keeping the adjustment mechanism relatively simple compared to having multiple fixed display units.

AI summary
A display device for a vehicle includes: a display unit including a display surface that is configured to display information to an occupant of a vehicle; a display control unit that is configured to set the information displayed at the display surface and a display area in which the information is displayed at the display surface; a drive unit that is configured to drive the display unit in and out of an interior member that is disposed in a vehicle cabin; and a drive control unit that is configured to control the drive unit such that the display area and an exposed area, of the display surface, which is exposed from the interior member are proportional to each other.
