Smart Wall Screen Drive for Stable Concealment of Mounted Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to provide a stable and space-efficient solution for mounting multimedia devices and home appliances on walls while minimizing the number of protruding furniture and electronics, especially addressing the safety concerns for children and maintaining a neat appearance.
Innovation Solution
A smart wall system with a frame structure that includes a mounting cell, a display device, a driving roller, a screen, and a motor for vertical movement, utilizing timing gears and belts for stable screen operation, and a metal mesh for support, allowing the screen to cover devices when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If multimedia devices and home appliances are mounted on the wall, then the number of protruding furniture is reduced and appearance is improved, but the screen becomes unstable and difficult to control
Solution Approach 1:
A fabric screen is introduced as an intermediary element that covers the multimedia devices when not in use, creating a neat appearance while allowing the devices to function normally. The fabric screen acts as a mediator between the need for aesthetic appearance and the functional requirements of the mounted devices.
Solution Approach 2:
The frame structure is divided into multiple mounting cells that can independently hold different devices. The screen is segmented to pass through specific cells while covering others, allowing selective exposure of devices based on usage needs.
2Ease of operation
If the screen is wound around the driving roller, then vertical movement is achieved, but the screen may slip or deform
Solution Approach 1:
A timing belt is introduced as an intermediary component between the driving roller and the screen. The timing belt with its toothed structure engages with the driving roller's teeth, providing positive engagement that prevents slipping while allowing smooth vertical movement of the screen.
Solution Approach 2:
The surface of the driving roller is coated with silicone or rubber material to change its friction characteristics. This parameter change in surface properties enhances the grip on the timing belt, ensuring reliable power transmission without slippage.
3Adaptability or versatility
If multiple devices are mounted in the living room, then functionality is improved, but safety risks increase for children
Solution Approach 1:
The fabric screen is extracted as a separate safety element that can cover potentially hazardous devices when not in use. This allows children-safe environments by hiding protruding devices while maintaining full functionality when needed.
4Ease of manufacture
If the frame structure is made deformable for easy installation, then ease of manufacture is improved, but structural strength may be compromised
Solution Approach 1:
The frame structure incorporates movable connections that allow the frame to be easily assembled and disassembled, yet maintain rigidity when installed. The dynamic nature of the connections enables easy manufacture while preserving structural strength during operation.
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, ensures stable vertical movement of the screen, reduces the need for separate storage, and enhances safety by minimizing protruding objects.
Implementation Method 1
The 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
The screen may include a first fabric, and a metal mesh positioned on a first surface of the first fabric

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.
