Automatically Folded LED Display Screen with Hinged Sub-Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED display screens are fixed and cannot be folded, occupying large areas when applied to building exteriors and failing to achieve artistic effects in stage and evening settings due to their rigid design.
Innovation Solution
An automatically folded LED display screen is designed with LED sub-displays hinged together, motors, and winding reels to facilitate automatic folding and unfolding, utilizing a tray connected to the bottom with steel wires for efficient space management and easy deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If LED display screen is designed as fixed flat panel, then display stability is improved, but adaptability to different scenarios deteriorates
Solution Approach 1:
The LED display screen transitions from a fixed flat panel to a dynamic structure that can fold and unfold. Each sub-display is hinged to adjacent sub-displays, allowing the entire screen to change its configuration between a flat display state and a folded storage state, thereby achieving adaptability while maintaining display stability when deployed.
Solution Approach 2:
The display screen is divided into multiple sub-displays that can be independently hinged together. This segmentation allows the screen to be folded section by section, enabling it to adapt to different installation scenarios such as building exteriors, stages, and evening parties while maintaining structural stability during operation.
2Productivity
If LED display screen is designed as fixed flat panel, then display functionality is improved, but space occupation deteriorates
Solution Approach 1:
The display screen employs a dynamic folding mechanism that allows it to occupy minimal space when not in use. The hinged sub-displays can be folded together like an accordion, reducing the space required for installation and storage while maintaining full display functionality when deployed flat.
Solution Approach 2:
The folding structure allows sub-displays to be nested within each other when folded, similar to nested dolls. This nesting capability enables the large display screen to be compacted into a small package for storage or transport, significantly reducing space occupation requirements.
3Manufacturing precision
If LED display screen is designed as fixed flat panel, then viewing clarity is improved, but dust accumulation deteriorates
Solution Approach 1:
The folding mechanism allows the display screen to be raised and folded away from the building surface, creating physical separation that prevents dust and debris from accumulating on the display surface. The screen can be stored in a compact position where it is protected from environmental contaminants while maintaining viewing clarity when deployed.
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 solution allows for compact storage and easy deployment, maintaining a clean surface by preventing dust accumulation and ensuring unobstructed viewing while not affecting daylighting, thus enhancing aesthetic and functional usability.
Implementation Method 1
start the motor to make the tray in a horizontal position... continue to run the motor and the winding reel winds the steel wires to drive the tray to move up smoothly
Implementation Method 2
LED sub-displays are hinged to each other along longitudinally... The bottom of LED display screen is connected to the tray by a hinge
Implementation Method 3
LED display screen will automatically unfold under the action of gravity when the tray descends
