Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED display screens are cumbersome to transport and assemble, prone to damage during handling, and require disassembly for installation, which is time-consuming and inefficient.
Innovation Solution
A foldable LED display screen design featuring embedded hinges and connecting pieces that allow for inward folding, with magnetic and locking mechanisms to secure the screens together, reducing the risk of damage and enhancing structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the LED display screen is made large-sized, then the display area is increased, but it becomes troublesome to transport, difficult to carry, and time-consuming to assemble and debug
Solution Approach 1:
The LED display screen is divided into multiple modular units that can be independently handled, transported, and assembled. Each module contains its own hinge structure, allowing the large display to be segmented into manageable sections that can be carried separately and quickly reassembled without requiring complex disassembly procedures.
Solution Approach 2:
The display screen incorporates foldable hinge mechanisms that enable dynamic transformation between unfolded (display) and folded (transport) states. This dynamic structure allows the screen to adapt its form factor based on operational needs, transitioning from a large rigid structure to a compact foldable configuration for easy transport.
2Ease of operation
If the LED display screen is disassembled for transfer, then it can be transported more easily, but it requires re-testing after installation which consumes a lot of manpower and time
Solution Approach 1:
The hinge structures and connecting mechanisms are pre-configured and pre-tested during manufacturing to ensure reliable connections. This preliminary preparation allows modules to be quickly assembled and immediately functional without requiring time-consuming re-testing after installation, as the connection integrity is guaranteed by the pre-engineered hinge system.
3Ease of operation
If outward-foldable LED display screens are used, then the folding function is achieved, but the module cannot be protected well and is prone to contact with external objects and damage
Solution Approach 1:
Instead of folding outward where the hinge mechanism is exposed to external objects, the hinge structures fold inward toward the center of the display module. This inverted folding direction protects the vulnerable hinge mechanisms and module edges by tucking them inside the folded structure, preventing contact with external objects during transport and storage.
4Ease of operation
If the folding mechanism is located outside of the screen body, then the folding function is accessible, but the integrity is not strong
Solution Approach 1:
The hinge mechanisms are nested within the screen body structure rather than being mounted externally. The connecting pieces are embedded into recesses in the display modules, creating a nested configuration where the folding mechanism is integrated within the overall structure. This nesting approach maintains structural integrity while preserving folding functionality, as the hinges are protected within the module boundaries.

AI summary
A foldable LED display screen includes a first display screen, a second display screen, and a hinge. The hinge includes a first hinge block, a second hinge block, a first connecting piece, and a second connecting piece. The first hinge block embedded in the first connecting end without protruding from the first connecting end, the second hinge block embedded in the second connecting end without protruding from the second connecting end. One end of the first connecting piece is slidably connected to the first hinge block, and another end of the first connecting piece is hinged to the second hinge block. One end of the second connecting piece is slidably connected to the second hinge block, and another end of the second connecting piece is hinged to the first hinge block. The second connecting piece is hinged with the first connecting piece through the hinge shaft.
