Motorized Rollable Front Cover for Display Panel Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices lack effective protective and storage structures that allow for easy concealment and deployment of the display panel while maintaining a compact form factor.
Innovation Solution
A display device design featuring a display panel, a module cover, a frame, and a front cover that can be opened or closed, utilizing a bar, rollers, pulleys, and a motor system to roll or unroll the front cover, along with a foldable link mechanism for up-down movement, providing a protective and storage solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a front cover is added to protect the display panel, then protection capability is improved, but device complexity increases
Solution Approach 1:
The front cover is designed to be movable rather than fixed, allowing it to slide along guide rails and be rolled up via a roller mechanism. This dynamic design provides protection when needed while allowing easy access when not needed, resolving the contradiction between protection capability and device complexity.
Solution Approach 2:
The front cover protection system is divided into separate functional components: the cover itself, guide rails for movement, a roller for rolling, and a motor for actuation. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability.
2Ease of operation
If a movable front cover system is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The motorized roller system automatically rolls up or unrolls the front cover without requiring manual intervention. The system serves itself by using the motor to perform the repetitive rolling action, making operation extremely easy while containing the complexity within the automated mechanism rather than requiring complex manual controls.
Solution Approach 2:
The manual mechanical operation of rolling and unrolling the front cover is replaced with an automated motor-driven system. This substitution eliminates the need for complex manual mechanisms while providing smooth, controlled movement through electrical actuation.
3Adaptability or versatility
If the display panel is made concealable, then adaptability is improved, but device complexity increases
Solution Approach 1:
The display panel system transitions from a static fixed configuration to a dynamic concealable configuration through the movable front cover. The cover can be positioned in multiple states (fully closed, partially open, fully rolled up), providing adaptability for different usage scenarios while using relatively simple mechanical components.
Solution Approach 2:
The front cover can be rolled up and stored within the device housing when not in use, similar to a nested doll structure. This nesting approach allows the concealable feature to be integrated into the existing device form factor without requiring excessive additional space or complexity.

Function Achieved in This Case
The solution offers a compact and flexible display device with a protective structure for the panel and a storage mechanism, allowing for easy concealment and deployment, enhancing usability and protection.
Implementation Method 1
a roller disposed adjacent to a lower end of the frame and configured to roll or unroll the front cover
Implementation Method 2
a bar extending in a left-right direction of the display panel and sliding on the frame
Implementation Method 3
a guide roller sliding and moving on the vertical frame, the guide roller being fixed to the bar
Implementation Method 4
a lower pulley installed at the vertical frame adjacent to the roller; an upper pulley installed adjacent to an upper end of the vertical frame; and a belt configured to connect the lower pulley and the upper pulley
Implementation Method 5
a motor mounted on the vertical frame and configured to provide a rotational force to the lower pulley
Implementation Method 6
a joint disposed between the motor and the lower pulley, wherein the joint may be configured to transfer the rotational force provided by the motor to the lower pulley
