Vehicle-Mounted Rollable Display Support for Compact Reliable Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges in designing a display screen that can efficiently roll up and expand, particularly in vehicle-mounted applications, due to the complexity and weight of drive mechanisms, which affect footprint, production costs, and handling convenience.
Innovation Solution
A vehicle-mounted display module with an auxiliary deformation device comprising a drive mechanism, securing mechanism, and support mechanism, allowing the deformable display screen to expand or roll up through a motor module, slider, and securing frame, which reduces weight and interference, and includes grooves and hollowed-out patterns to enhance mobility and reduce material costs.

Engineering Contradiction Analysis
1Volume of moving object
If a flexible display screen is designed to bend and roll up, then space utilization is improved, but the reliability of the display screen is compromised
Solution Approach 1:
The display system is divided into a rigid support mechanism and a flexible display screen that can be independently secured or released. The support mechanism includes a motor module, slider, and securing frame that provide structural stability, while the display screen can be segmented into display and storage portions through the securing mechanism.
Solution Approach 2:
The securing mechanism is pre-configured with a securing frame and motor module that can automatically secure the display screen before bending operations. This preliminary securing action prevents damage during the rolling process and ensures reliable operation when the display is in use.
2Reliability
If a securing mechanism is added to secure local structures, then reliability is improved, but device complexity increases
Solution Approach 1:
The securing frame serves multiple functions: it provides structural support for the motor module, acts as a securing structure for the display screen, and guides the slider movement. The motor module both drives the slider and secures the display screen through integrated components.
Solution Approach 2:
The securing mechanism merges the motor module, securing frame, and slider into a single integrated assembly. The motor module is mounted on the securing frame, and the slider moves along the securing frame, combining driving and securing functions in one compact mechanism.
3Adaptability or versatility
If a support mechanism is added to drive reciprocation, then functionality is improved, but device complexity increases
Solution Approach 1:
The support mechanism provides multiple functions through a single slider component: it supports the display screen during bending, guides the rolling motion, and transfers drive force from the motor module. The same mechanism enables both expansion and rolling-up operations.
Solution Approach 2:
The slider moves dynamically along the securing frame, changing its position to accommodate different operational states. The support mechanism transitions from a static support structure to an active driving mechanism through the reciprocating motion of the slider, enabling versatile display functionality.
