Flexible Vehicle Display Winding for Space and Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display devices face limitations in space utilization, as fixed installations reduce forward visibility and require additional space for larger displays, and power inefficiencies arise from constant operation regardless of display exposure.
Innovation Solution
A flexible display device with a retractable and extendable design, utilizing magnets, guides, and a motor-driven mechanism to control display exposure, along with a sensor system to manage power usage based on display position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed display is installed in a vehicle, then the display can provide visual information, but the installation position is fixed which limits space utilization and forward visibility
Solution Approach 1:
The display device transitions from a fixed installation to a movable one, capable of moving up and down or left and right along a guide. This dynamic positioning allows the display to be adjusted according to different usage scenarios, improving space utilization while maintaining forward visibility when not in use.
Solution Approach 2:
The display device is divided into separate functional components: the display screen, the guide mechanism, and the motor-driven actuation system. This segmentation allows independent optimization of each component, enabling the display to move along the guide without affecting the overall vehicle structure.
2Adaptability or versatility
If a pop-up style movable display is used, then the display can be stored and extended, but a separate accommodation space is required which increases the size of the accommodation space
Solution Approach 1:
The display device is nested within the dashboard structure, moving along a guide that is integrated into the dashboard. The motor-driven mechanism is compact and integrated into the accommodation space, allowing the display to extend and retract without requiring additional external space.
3Loss of information
If an entire LCD screen is operated, then the display can show full-screen information, but all power is used regardless of the degree of exposure
Solution Approach 1:
The display system implements selective activation of display regions based on the exposed area. When the display is partially extended, only the exposed portion is activated, reducing power consumption while maintaining complete information display in the visible region.
4Adaptability or versatility
If a movable display device with guide and motor mechanism is implemented, then the display can move and adjust position, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical positioning systems with a motor-driven mechanism that moves the display along a simple guide. The guide provides structural support and movement constraints, while the motor provides precise actuation, simplifying the overall mechanical complexity.
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
The device minimizes space requirements, enhances visibility by adjusting display size, and optimizes power consumption by only activating exposed areas.
Implementation Method 1
The display part and the rear protection cover may include a plurality of magnets provided at related positions in a vertical direction, and the rear protection cover may be attached to and detached from the display part by a magnet.
