Slidable Display Panel Transfer Path for Stable Roof Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slidable display devices face challenges in ensuring stability and durability of the display panel during sliding operations, particularly when mounted on vehicle roof panels.
Innovation Solution
A slidable display device design that includes a mounting frame, a display panel assembly with an always-on display area and an expanded display area, and a guide roller assembly with a panel transfer path featuring a first path, a second path inclined with respect to the first path, and a third path with curvature, allowing the display panel to slide and extend while maintaining stability and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel is made slidable to enable expansion and contraction, then the display area can be adjusted dynamically, but the stability and durability of the display panel during sliding operations deteriorates
Solution Approach 1:
A transfer assembly is introduced as an intermediary mechanism between the mounting frame and the display panel. This transfer assembly includes a panel transfer path with curved sections and guide rollers that mediate the sliding motion, protecting the display panel from direct mechanical stress while enabling area adjustment. The intermediary mechanism absorbs the mechanical complexity, allowing the display panel to change area without compromising its stability.
Solution Approach 2:
The system is segmented into distinct functional components: a fixed mounting frame, a movable transfer assembly, and the display panel. The transfer assembly is further segmented into guide rollers and curved path sections. This segmentation allows each component to be optimized independently - the mounting frame provides structural stability while the transfer assembly handles the dynamic movement, resolving the contradiction between adaptability and reliability.
2Adaptability or versatility
If the display panel slides along a curved path to accommodate roof panel geometry, then the device can be mounted on vehicle roofs, but the mechanical complexity of the transfer path increases
Solution Approach 1:
The panel transfer path incorporates curved sections instead of straight lines, specifically designed to match the geometric constraints of vehicle roof mounting. The curved paths allow the display panel to navigate around obstacles and accommodate the contoured surface of vehicle roofs. This curvature application enables versatile mounting while the modular guide roller assembly keeps the implementation manageable.
Solution Approach 2:
The transfer assembly is designed as a dynamic system where guide rollers can move along the curved transfer path. This dynamic configuration allows the same mechanism to accommodate different curvature radii and path geometries, enabling vehicle roof mounting without requiring completely different structures for each application scenario.
3Adaptability or versatility
If the display panel is transferred through curved paths, then it can accommodate mounting on vehicle roofs, but the stress and potential damage to the display panel increases
Solution Approach 1:
The transfer assembly incorporates cushioning elements and smooth curved transitions beforehand to prevent sudden stress impacts on the display panel. The curved paths are designed with appropriate radii to avoid sharp angles that would concentrate stress. Guide rollers are positioned to distribute mechanical loads evenly across the panel edges, preventing localized damage while enabling vehicle roof mounting.
Solution Approach 2:
Guide rollers act as intermediary elements between the curved transfer path and the display panel. These rollers convert the curved path geometry into gentle rotational movements of the panel, rather than direct bending stresses. The intermediary rollers protect the panel's structural integrity while still achieving the necessary curved transfer for vehicle mounting applications.

AI summary
A slidable display device in one example includes a display panel assembly including a display panel having a first display area and a second display area extending from the first display area, and a mounting frame. The display panel assembly can be movable in the mounting frame between a first position and a second position, the first position corresponding to a position in which the first display area extends beyond the mounting frame at a predetermined angle with respect to a portion of the second display area, and the second position corresponding to a position in which the first display area and the second display area extend at the predetermined angle beyond the mounting frame.
