Retractable Vehicle Display Structure for Space and Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display devices face challenges with limited space utilization, reduced forward visibility, and inefficient power usage due to fixed installations or pop-up designs, which do not efficiently accommodate varying display sizes.
Innovation Solution
A flexible display device with a display support unit, including a housing, door, and door driver, which allows the display to retract or extend, and a display driver with motors and winders to control the display's exposure and movement, enhancing rigidity and reducing space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed display installation position is used, then the display structure is simple, but the space utilization in the vehicle is limited
Solution Approach 1:
The display device transitions from a fixed installation to a movable structure that can dynamically adjust its position and exposure degree. The housing can rotate around a rotation axis, and the display can be selectively exposed or retracted, enabling adaptive space utilization while maintaining operational simplicity through automated control.
2Adaptability or versatility
If a pop-up style movable display is used, then the display can be extended when necessary, but a separate accommodation space is required which limits space utilization
Solution Approach 1:
The display structure is nested within the housing in a compact configuration. When not in use, the display is retracted into the housing, utilizing the same space for both accommodation and operation. The housing itself serves as the accommodation structure, eliminating the need for separate dedicated spaces.
3Illumination intensity
If the entire screen is operated in LCD mode, then the display is always visible, but power is used inefficiently regardless of exposure degree
Solution Approach 1:
Instead of operating the entire display screen at full capacity, the system selectively exposes only the necessary portion of the display based on current needs. The housing rotation and display retraction mechanisms enable partial exposure, allowing the display to be visible when needed while consuming less power by reducing the active display area.
4Area of moving object
If the display size increases, then the display provides more information, but the forward visibility decreases
Solution Approach 1:
The display system dynamically adjusts its effective size and position through rotational movement of the housing and selective retraction of the display. This allows a larger display to be accommodated without permanently blocking the forward view, as the display can be rotated away or retracted when not in use, maintaining forward visibility while providing large display capability when needed.
