Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing frames for arc-shaped LED display screens have poor dimensional accuracy, angular accuracy, and structural strength, requiring additional steel structures for support and preventing individual installation.
Innovation Solution
A frame composed of top and bottom partition panels with primary, secondary, module, left, and right supports, which are equally spaced and fixed to achieve seamless assembly and enhanced structural strength, allowing direct force bearing without additional steel structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a sheet metal frame or profile frame is used for arc-shaped LED display screen, then the frame can be manufactured with simple processes, but the dimensional accuracy and angular accuracy of assembled LED modules deteriorate
Solution Approach 1:
The frame is divided into multiple partition panels (first partition panel, second partition panel, etc.) with arc edges that are equally spaced. Each partition panel is independently manufactured and then assembled together, allowing for precise control of dimensional accuracy while maintaining manufacturing simplicity through modular production
Solution Approach 2:
The partition panels are designed with specific arc-shaped edges that match the curvature requirements of the arc-shaped LED display screen. This local geometric precision ensures that when modules are assembled along the arc edges, the angular accuracy and dimensional consistency are maintained throughout the entire structure
2Ease of manufacture
If a sheet metal frame or profile frame is used, then the manufacturing cost is reduced, but the structural strength deteriorates requiring additional steel structures
Solution Approach 1:
Multiple partition panels are combined and fixed together to form a unified frame structure. The collective arrangement of these panels creates enhanced structural strength that can support the arc-shaped LED display screen without requiring additional steel reinforcement structures
Solution Approach 2:
The partition panels are pre-assembled into a complete frame structure before installing the LED modules. This preliminary formation of the integrated frame ensures that the structural strength is established in advance, eliminating the need for additional support structures during final assembly
3Device complexity
If a sheet metal frame or profile frame is used, then the frame structure is simplified, but the stability and flatness of assembled LED modules deteriorate
Solution Approach 1:
The frame is segmented into multiple partition panels that are equally spaced and arranged in sequence. This segmentation allows each panel to maintain its structural integrity and flatness independently, while the overall assembly achieves stability through the regular, evenly-distributed configuration of all panels
Solution Approach 2:
All partition panels are designed with identical arc edge characteristics and are equally spaced from each other. This homogeneous arrangement ensures uniform distribution of structural loads and maintains consistent flatness across the entire frame, providing stable support for the LED modules

AI summary
A frame for installing an arc-shaped LED display screen composed of a plurality of LED display modules. The top partition panel and the bottom partition panel have arc edges with the same arc, and are parallel to and spaced apart from each other and both fixed to the primary support, the secondary support, the plurality of module supports, the left support, and the right support. The left support, the right support, and the plurality of module supports are equally spaced apart and fixed along the arc edge of each of the top partition panel and the bottom partition panel, and are configured to connect the plurality of LED display modules, to achieve a seamless assemblage of the arc-shaped LED display screen.
