Solution Overview
Problem
Existing support structures for LED display screens have complex structures and poor flexibility, making them inconvenient for quick assembly/disassembly, transportation, and temporary adjustments, limiting their adaptability to specific site requirements.
Innovation Solution
A B-shaped support frame system comprising two first support bars and three second support bars, connected through plugging holes and limiting step sections, allowing for easy assembly and disassembly, and adjustable to match varying display screen sizes and orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional steelwork frames are used for LED display screens, then structural strength is ensured, but assembly complexity increases and flexibility decreases
Solution Approach 1:
The support frame is divided into multiple modular units, each comprising a plurality of support bars connected through connection pieces. These modular units can be independently assembled and then combined to form the complete support frame, significantly reducing assembly complexity while maintaining structural strength.
Solution Approach 2:
The connection pieces are designed with detachable features allowing the support bars to be easily connected and disconnected. This dynamic connection mechanism enables quick assembly and disassembly operations, transforming the traditionally static and complex welding process into a flexible mechanical connection system.
2Stability of the object's composition
If welded steelwork frames are used, then structural stability is achieved, but adaptability to different site requirements is reduced
Solution Approach 1:
The frame is segmented into standardized modular units that can be configured in different arrangements. By varying the number and configuration of these modular units, the support frame can be adapted to different site requirements and display screen sizes while maintaining structural stability through consistent modular connections.
Solution Approach 2:
The connection pieces are designed with universal features that can accommodate different support bar configurations and orientations. This universality allows the same modular units to be used in various arrangements, providing adaptability to different site requirements without compromising structural stability.
3Ease of manufacture
If fixed-area support frames are used, then manufacturing simplicity is maintained, but flexibility in area adjustment is lost
Solution Approach 1:
The support frame consists of standardized modular units that can be easily manufactured using the same processes for each unit. The overall area is adjusted by varying the number of modular units assembled together, maintaining manufacturing simplicity while providing flexible area adjustment capability.
4Strength
If complex welded structures are used, then load-bearing capacity is ensured, but assembly time increases
Solution Approach 1:
The detachable connection pieces enable dynamic assembly and disassembly operations, replacing time-consuming welding processes. The mechanical connection mechanism maintains load-bearing capacity while dramatically reducing assembly time through simple connection and disconnection actions.
Solution Approach 2:
The modular units are pre-assembled with connection pieces attached during manufacturing. This preliminary action allows the complex connection features to be prepared in advance, so that during on-site assembly, only simple connection operations are required, significantly reducing assembly time while ensuring load-bearing capacity.
