Cabinet Projection Screen With Automatic Push-Pull Space Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projection screens occupy specific positions, limiting space in urban areas where work or living spaces are compact, necessitating versatile office furniture that can integrate multiple functions, including projection, in a small space.
Innovation Solution
A cabinet projection screen with an automatic push-pull structural function, featuring a sliding screen base, scrolling mechanism, telescopic device, and control system, allowing it to function as both an office desk and a projection screen, utilizing sliding rails, motors, and an elastic mechanism for efficient deployment and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional projection screen is suspended in an office, then a large-screen display function is achieved, but the screen occupies a specific position and limits the available work or living space
Solution Approach 1:
The cabinet is designed to serve dual purposes: as a normal storage cabinet and as a projection screen. The cabinet body contains both storage compartments and a projection screen that can be deployed from the cabinet, allowing the same object to fulfill multiple functions and eliminate the need for separate projection screen equipment
Solution Approach 2:
The projection screen is nested within the cabinet body structure. The screen can be stored inside the cabinet when not in use and deployed outward when needed, allowing the projection function to be integrated into the cabinet without requiring additional dedicated space
2Area of stationary object
If the screen is integrated into the cabinet, then space is saved, but the mechanism for deploying and retracting the screen becomes complex
Solution Approach 1:
The cabinet incorporates a telescopic device with movable components that allow the screen to be extended and retracted. The telescopic structure includes sliding parts and connecting mechanisms that enable dynamic transformation between the compact cabinet state and the deployed screen state, making the transition smooth and controllable
Solution Approach 2:
The telescopic device is designed to automatically extend and retract the screen without requiring manual assembly or disassembly. The mechanical structure includes self-locking and self-guiding features that allow the screen to deploy and return to its storage position autonomously when actuated
3Ease of operation
If the screen is made telescopic and movable, then deployment flexibility is improved, but the structural stability and reliability may be compromised
Solution Approach 1:
The telescopic device incorporates buffering and damping mechanisms that prevent sudden movements or impacts during screen deployment and retraction. The structure includes cushioning elements at critical connection points to absorb shocks and maintain stability throughout the motion cycle, ensuring reliable 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
Enables a multi-functional office solution that can be used as a normal desk or cabinet when not projecting, providing a large-screen display function without occupying additional space, enhancing usability in limited environments.
Implementation Method 1
When the scrolling motor drives the scrolling shaft to rotate, the scrolling shaft winds the tape on the scrolling shaft, so as to drive the screen push-pull base to move towards one side of the scrolling shaft through the tape
Implementation Method 2
The scroll is disposed on the screen push-pull base. The projection screen is wound on the scroll. One end of the compression frame is fixed on a free end of the projection screen
Implementation Method 3
An elastic mechanism is installed on the compression frame. Two ends of the elastic mechanism are installed on the adjacent support rods, respectively

AI summary
A cabinet projection screen with an automatic push-pull structural function is provided, which includes a cabinet body (1). A screen push-pull base (13) is disposed on the cabinet body (1) through sliding rails (2, 4, 10, and 11). A scrolling mechanism (6) is disposed inside the cabinet body (1), and includes a scrolling shaft (61), a scrolling motor (8), a tape (62), and a telescopic device (7). One end of the tape (62) is fixed on the scrolling shaft (61), and the other end thereof is fixed on the screen push-pull base (13). When the scrolling motor (8) drives the scrolling shaft (61) to rotate, the scrolling shaft (61) winds the tape (62) on the scrolling shaft (61), so as to drive the screen push-pull base (13) to move towards one side of the scrolling shaft (61) through the tape (62), and at the same time the screen push-pull base (13) compresses the telescopic device (7). An elevator screen (12) is disposed on the screen push-pull base (13). The cabinet projection screen has advantages of versatility and occupying no space.
