Retractable Display Panel with Telescopic Support Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices struggle to provide an immersive viewing experience while maintaining a compact form factor, as they often compromise on screen thickness and user interaction due to bulky support structures and complex mechanisms.
Innovation Solution
A display device design featuring a retractable display panel and module cover system, utilizing a panel roller and motor assemblies to wind or unwind the display panel and module cover simultaneously, allowing for a thinner profile and improved user immersion by minimizing obstructions and enhancing mechanical stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional support structures are used, then mechanical stability is maintained, but the display device becomes bulky and loses immersive quality
Solution Approach 1:
The patent employs dynamic support arms with telescopic mechanisms that can extend and retract. When the display panel is in use, the support arms extend to provide full mechanical stability. When retracted, they minimize the profile thickness to enhance immersion. This dynamic adjustment allows the system to optimize both structural support and immersive quality at different operational states.
Solution Approach 2:
The support arms are designed with nested telescopic sections that can be stored within each other when not in use. This nesting mechanism allows the support structures to occupy minimal space during retraction, reducing the overall device bulk while maintaining the capability to provide robust support when extended.
2Ease of manufacture
If the display panel is made thinner for immersion, then user immersion is improved, but mechanical stability and protection are compromised
Solution Approach 1:
The display panel is designed to dynamically change its operational state between extended (for viewing) and retracted (for protection). When extended, the panel provides a thin profile for immersion. When retracted into the housing, it gains mechanical protection and stability. The telescopic support arms dynamically adjust to maintain stability in both states.
Solution Approach 2:
The housing structure is designed with recesses and guide rails that cushion and guide the display panel during retraction. This beforehand cushioning mechanism prevents damage to the thin display panel by controlling its movement and absorption of mechanical stress, ensuring reliability during the transition between extended and retracted states.
3Device complexity
If complex mechanisms are used for support, then mechanical stability is maintained, but ease of operation is reduced
Solution Approach 1:
The telescopic support arms are equipped with self-locking mechanisms that automatically lock into position when extended or retracted. This self-service feature eliminates the need for manual adjustment or complex control systems, allowing the display panel to stabilize itself automatically. Users simply need to initiate the extension or retraction, and the system handles the positioning and locking autonomously.
Solution Approach 2:
The patent replaces complex mechanical adjustment mechanisms with a streamlined system using spring-loaded telescopic arms and magnetic or friction-based self-locking features. This substitution reduces the number of moving parts and control elements required, simplifying the overall system while maintaining mechanical stability and ease of operation.

AI summary
A display device is disclosed. The display device includes: a housing; at least one roller configured to be positioned within the housing; and a display portion including a display panel and a module cover, wherein the display panel and the module cover are either in a first state where the display panel and the module cover are kept wound around the at least one roller or in a second state where the display panel and the module cover are kept unwound from the at least one roller, in contact with each other, and exposed out of the housing, and wherein the module cover is configured to be divided into a plurality of sections. In the display device, supports are positioned between first and third module covers so that the supports are shielded from the outside, allowing the user to immerse themselves into the display screen.
