Retractable Smart Wall Screen for Stable Vertical Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a smart wall that can stably drive a screen on its front surface, while also allowing for easy mounting and deformation of the frame to accommodate multimedia devices and home appliances.
Innovation Solution
A smart wall with a frame structure containing a mounting cell, a display device, a driving roller, a screen that winds around the roller, and a motor to move the screen. The system includes a timing gear and belt mechanism for smooth operation, and a metal mesh and fabric combination for the screen to maintain rigidity and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a TV table or loudspeaker is placed in the living room, then multimedia devices can be easily accessed and used, but the number of protruding elements increases causing safety hazards and messy appearance
Solution Approach 1:
The patent extracts the screen from the wall structure and makes it movable, allowing the screen to be taken out when needed and retracted when not in use. This eliminates the need for permanent protruding furniture while maintaining accessibility to multimedia devices.
Solution Approach 2:
The patent introduces a movable screen that can dynamically change its position between extended and retracted states. This dynamic structure replaces static protruding furniture, providing accessibility when needed while eliminating safety hazards when not in use.
2Ease of operation
If a TV table or loudspeaker is placed in the living room, then multimedia devices can be easily accessed and used, but the appearance of the living room wall becomes messy
Solution Approach 1:
The screen is extracted from the wall structure and made independently movable, allowing the wall to maintain a clean, flush appearance when the screen is retracted, while still providing accessibility when extended.
Solution Approach 2:
The dynamic screen mechanism allows the wall to transition between a clean minimalist appearance and a functional state with accessibility, eliminating the need for permanent protruding furniture that would permanently mar the wall's appearance.
3Ease of operation
If a screen is made flexible to wrap around the driving roller, then the screen can be moved vertically, but the screen may deform or lose structural integrity
Solution Approach 1:
The patent uses a composite structure combining fabric and metal mesh. The fabric provides flexibility for wrapping around the roller and vertical movement, while the metal mesh embedded within provides structural integrity and prevents deformation, resolving the contradiction between flexibility and stability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The smart wall provides a neat appearance by covering electronic appliances with a screen when not in use, ensures stable vertical movement of the screen, and reduces the risk of injury from protruding furniture by minimizing the number of protruding elements.
Implementation Method 1
An outer surface of the driving roller may be coated with a silicone or rubber material
Implementation Method 2
a timing gear rotating by receiving a rotational force of the motor and including first teeth on an outer surface thereof, and a timing belt coupled to a first surface of the screen in contact with the driving roller and including second teeth engaged with the first teeth
Implementation Method 3
a motor for moving the screen wound around the driving roller

AI summary
A smart wall comprises: a frame structure comprising a mounting cell; a display device installed in the mounting cell; a driving roller provided above the mounting cell; a screen which is wound around the driving roller and comprises a first lower side portion located at the front side of the display device and a second lower side portion located at the rear side of the display device; and a motor for moving the screen wound around the driving roller, to thereby enable the screen, which covers the front surface of the display device, to receive the force of the motor without slipping, to thus be stably moved upward or downward.
