Tool-Free Connection Assembly for Extruded Aluminum Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display frame constructions require tools for erection and dismantling, are not robust enough for frequent use, and often necessitate cutting elongate members to accommodate different arrangements and sizes of display panels.
Innovation Solution
A connection assembly with movable engagement members and a control member, allowing for tool-free assembly and disassembly, and adjustable positioning without cutting, using a sliding link member and spring-urged engagement mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing frame constructions are used, then tools are required for erection and dismantling, but this makes operations complex and tools may not always be available
Solution Approach 1:
The connection assembly enables tool-free operation through a self-contained mechanism where the control member directly actuates the engagement members. The spring-loaded design provides automatic engagement and disengagement without requiring external tools, making the system self-sufficient and easy to operate.
2Reliability
If existing frame constructions are used, then erection and dismantling can be performed, but they are not robust enough to survive regular use
Solution Approach 1:
The connection assembly incorporates dynamic elements including spring-loaded engagement members that automatically adjust during engagement and disengagement. The movable engagement members provide controlled motion while maintaining structural integrity, enabling the assembly to withstand repeated operational cycles without degradation.
3Adaptability or versatility
If elongate members are cut to required lengths, then different arrangements and sizes of display panels can be supported, but this increases manufacturing complexity and waste
Solution Approach 1:
The connection assembly divides the elongate member into modular segments with standardized connection points. The engagement members can selectively engage with different positions along the elongate member, allowing various configurations without cutting. This segmentation enables flexibility while maintaining complete member lengths for easier manufacturing.
4Strength
If engagement members are spaced further apart in engaged condition, then secure connection is achieved, but this increases the size of the connection assembly
Solution Approach 1:
The connection assembly employs a nested configuration where the control member fits within the hollow end of the elongate member, and the engagement members are positioned to engage with features on the other elongate member. This nesting minimizes the overall volume while maintaining the necessary engagement spacing for strong connections.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables tool-free, robust connection and disconnection of elongate members at any position, accommodating various sizes and arrangements without cutting, and supports display materials without protruding handles.
Implementation Method 1
The second engagement member may be spring urged to a disengaged condition, and a spring may extend between the second engagement member and the frame member.
Implementation Method 2
the assembly includes a frame member which slidingly mounts a link member, which link member connects between the control member and a one of the engagement members for moving the latter

AI summary
A connection assembly (10) usable for interconnecting two extruded square section aluminium elongate members (12). The assembly (10) includes a frame member (18) which locates in an end of the elongate member (12), with a pair of engagement members (28, 38) extending from the elongate member (12). A second engagement member (38) is movable relative to the first engagement member (28) so as to grip in a channel (14) on the other of the elongate members (12) to hold the elongate members (12) together. The second engagement member (38) is movable by a pivotally mounted handle (52) which extends outwardly from the elongate member (12) when the assembly (10) is in an unlocked condition, but locates substantially wholly within a channel (14) when the assembly (10) is in a locked condition.
