LED Display Fast Assembly Mechanism for Installation Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED display devices have low installation efficiency, require manual alignment with high accuracy, and lack flexibility in adjusting screen distances, leading to unstable installations and increased labor costs.
Innovation Solution
A fast assembly mechanism using a motor screw structure and nut connection allows for precise alignment and adjustment of adjacent display screens, enabling efficient installation by powering the deceleration motor only after alignment, which shortens the distance between screens to meet installation requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation is used to fix display screens to the installation frame, then the installation can be completed, but the installation efficiency is low (1 m2/37 minutes)
Solution Approach 1:
The patent replaces manual mechanical fastening operations with an automated motor-driven screw fastening system. The motor automatically drives the screw to rotate and advance, eliminating the need for manual drilling and fastening operations, thereby significantly improving installation efficiency
Solution Approach 2:
The motor screw fastening structure enables the display screen to perform its own fastening operation automatically. The system self-aligns and self-fastens to the installation frame without requiring external manual intervention for each fastening operation, thus reducing installation time
2Manufacturing precision
If manual alignment is used during installation, then the display screens can be positioned, but the alignment accuracy is difficult to control and installation stability is compromised
Solution Approach 1:
The patent replaces manual alignment operations with an automated motor-driven positioning system. The motor precisely controls the movement and positioning of the display screen, ensuring accurate alignment with the installation frame and maintaining consistent positioning accuracy across all installations
Solution Approach 2:
The system changes the control parameter from manual visual estimation to motor-controlled precise positioning. The motor can be controlled to move the display screen by exact distances and positions, transforming the alignment process from an imprecise manual operation to a precise automated operation with controllable parameters
3Adaptability or versatility
If display screens are fixed rigidly to the installation frame, then the installation is stable, but the distance between adjacent screens cannot be adjusted according to customer needs
Solution Approach 1:
The patent transforms the rigid fixed connection into a dynamic adjustable connection using a motor-driven screw mechanism. The display screen can be positioned at different distances from the installation frame by controlling the motor's movement, allowing flexible adjustment while maintaining stable fixation once positioned
Solution Approach 2:
The motor screw fastening structure serves multiple functions: it provides stable fixation, enables distance adjustment, and allows repositioning. This multi-functional component replaces the simple rigid connector, giving the installation system both stability and adaptability to different customer requirements

AI summary
The invention presents an LED display device featuring a highly efficient installation method. It consists of display screens arranged in a matrix, with adjacent screens connected via a rapid assembly. This assembly includes a motor screw structure affixed to one screen and a nut structure fixed to the adjacent screen. The motor screw structure incorporates a deceleration motor and a screw fixed on the screen, while the nut structure comprises a nut fixed on the screen via a mounting plate. During assembly, power is applied only after alignment, allowing the deceleration motor to rotate the screw. The nut then adjusts the distance between screens until installation requirements are met, enhancing installation efficiency.
