Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current support frames for LED display screens are complex in assembly and disassembly due to improper structural designs, making them inconvenient for use, especially in outdoor settings where reliability under environmental challenges like wind and rain is a concern.
Innovation Solution
A support frame with a first rod and a bracket, featuring a connection assembly with a detachable connection portion that has locking and unlocking positions, and a positioning portion to secure the connection, allowing for easy assembly and disassembly, and a second connection assembly for enhanced structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional support frames are used to ensure structural strength and reliability, then the connection strength between splicing units is improved, but the assembly and disassembly complexity increases
Solution Approach 1:
The support frame is divided into multiple detachable connection assemblies, each consisting of separate components (connection portions, positioning portions, locking mechanisms) that can be independently assembled and disassembled. This segmentation allows the frame to maintain structural integrity when connected while enabling simple step-by-step assembly and disassembly operations.
Solution Approach 2:
The connection assembly incorporates movable locking mechanisms and positioning portions that can transition between locked and unlocked states. This dynamic design allows the connection strength to be actively controlled - providing strong fixed connections during operation while enabling quick release during assembly and disassembly, thus resolving the contradiction between reliability and assembly complexity.
2Strength
If traditional support frames are used to ensure structural strength, then the connection strength between splicing units is improved, but the time required for assembly and disassembly increases
Solution Approach 1:
The connection assembly is pre-configured with positioning portions and locking mechanisms that automatically engage when components are brought together. This preliminary arrangement of functional elements ensures that strong connections are formed quickly without requiring complex manual alignment or multiple fastening steps, thus reducing assembly time while maintaining connection strength.
Solution Approach 2:
The design replaces traditional complex mechanical fastening systems (multiple bolts, welds, or permanent connectors) with a simplified locking mechanism that achieves equivalent or superior connection strength through clever mechanical geometry. This substitution reduces the number of steps required to achieve strong connections, thereby reducing assembly and disassembly time.
3Ease of operation
If simple connection structures are used to reduce assembly complexity, then the ease of assembly and disassembly is improved, but the connection strength between splicing units deteriorates
Solution Approach 1:
The connection assembly is designed to be self-aligning and self-locking through its geometric features. The positioning portions automatically guide components into correct alignment, and the locking mechanisms engage automatically when components are connected. This self-service design maintains simple, easy assembly operations while ensuring strong, reliable connections without requiring complex manual intervention or additional fastening steps.

AI summary
This application discloses a support frame (20) and an LED display screen system (100) including the support frame (20). An LED display screen (10) includes a plurality of splicing units (11) that are spliced to each other. The support frame (20) includes a bracket (22) and a first rod (21) extending in a first direction. The bracket (22) includes a second rod (221) and a first connection assembly (222), and one end of the second rod (221) is connected to the first rod (21) and extends in a second direction. The first connection assembly (222) includes a connection portion (222a) and a first positioning portion (222c), and the connection portion (222a) is disposed on the other end of the second rod (221) and is configured to form a detachable connection with the splicing unit (11). The connection portion (222a) has a locking position and an unlocking position, the connection portion (222a) is relatively fixed to the splicing unit (11) when being in the locking position, and the connection portion (222a) is detachable from the splicing unit (11) when being in the unlocking position, thereby facilitating assembly and disassembly of the LED display screen (10).
