Graphics Frame Connector Assembly for Tool-Free Modular Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional graphic frames are difficult to assemble due to rigid materials and require strong force, which can reduce their lifespan, and existing methods are costly and time-consuming for disassembly and reassembly.
Innovation Solution
A graphic frame system with frame sections and connectors featuring sliding channels and protrusions that allow for easy assembly without tools, forming a square or rectangular shape with embedded graphics, using retainers and connectors to secure the frame and graphic in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional rigid frame sections are assembled end-by-end without connectors, then the frame structure is simple and manufacturing cost is low, but the assembly requires over-strong force which decreases the lifespan of the frame
Solution Approach 1:
The frame is divided into multiple frame sections that can be disassembled and reassembled. Each frame section has a joint portion with internal structure that allows connection through protrusions and recesses, enabling modular assembly without requiring excessive force while maintaining structural integrity
Solution Approach 2:
Protrusions and recesses act as intermediary elements between frame sections. The protrusions on one frame section fit into the recesses of adjacent sections, providing a mechanical interface that enables easy assembly and disassembly while protecting the frame sections from damage
2Stability of the object's composition
If L-shaped brackets are incorporated with frame sections to secure corners, then the frame structure is more stable, but the assembly method becomes more complex and time-consuming
Solution Approach 1:
The corner connection function is merged into the frame sections themselves through integrally formed joint portions with protrusions and recesses. This eliminates the need for separate L-shaped brackets, simplifying the assembly process while maintaining corner stability and overall frame rigidity
3Loss of substance
If frame sections are disassembled into small components for shipping, then shipping costs are reduced, but reassembly becomes more difficult and time-consuming
Solution Approach 1:
The frame sections are pre-formed with integrated joint portions including protrusions and recesses during manufacturing. This preliminary preparation of connection features allows the disassembled components to be easily reassembled by simply connecting the pre-configured joint portions without requiring complex assembly procedures or additional tools

AI summary
A system for holding a graphics on a graphics frame includes: a plurality of frame sections being assembled to form the graphics frame; a plurality of connectors configured to connect two vertically-arranged frame sections; wherein one of the frame sections includes two retainers received in two end portions of the frame section, wherein each of the retainers has two sliding channels; wherein each of the connectors includes at least two pairs of the protrusions and a receiving cavity for receiving the graphics; wherein one pair of the protrusions are engaged with the two of the sliding channels on one of the two retainers when the other pair of the protrusions are engaged with the two sliding channels on the other one of the two retainers to connect two vertically-arranged frame sections.
