Profile Connector Torsion-Proof Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing profile connectors for light metal alloy profile bars fail to provide a reliable, torsion-proof connection and even force distribution due to uneven pressure application and the need for separate parts, leading to twisting and assembly challenges.
Innovation Solution
A profile connector with a forming geometry that reshapes the first profile bar upon assembly, creating a positive locking fit and preventing twisting, while using angled clamping screws and an anchor bolt to ensure even force distribution and simplify assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the anchor bolt is tightened until immovable to ensure secure connection, then the connection strength is improved, but the second profile bar cannot be pushed onto the body
Solution Approach 1:
The patent applies preliminary action by providing a defined gap between the bracing leg and the first profile bar before final tightening. This gap allows the second profile bar to be pushed onto the body during assembly, and only after this preliminary positioning is complete should the anchor bolt be fully tightened to achieve the final secure connection.
2Device complexity
If the clamp screw causes the body to tilt relative to the anchor bolt to apply pressing force, then the force application is simplified, but the pressing force is not applied evenly over the full area
Solution Approach 1:
The patent applies local quality by providing a bearing surface on the body that extends perpendicular to the longitudinal extension of the body. This bearing surface is specifically designed to distribute the pressing force evenly over the full area of the undercut elongated groove of the second profile bar, rather than concentrating force at a single point or along a line.
3Reliability
If multiple separate parts are used to achieve reliable connection, then the connection reliability is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single integrated body structure. The body combines the anchor bolt positioning function, the bracing leg for force application, and the bearing surface for even force distribution, eliminating the need for multiple separate parts while maintaining connection reliability through the integrated design.
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
The solution provides a torsion-proof connection, allows for defined preassembly, and reduces the number of parts required, ensuring reliable attachment and even force application across the undercut groove.
Implementation Method 1
designed and arranged to displace the body along the anchor bolt away from the screw head, towards the first profile bar, by tightening the clamping screw in the internal thread, in other words by screwing the clamping screw towards the anchor bolt and at the same time bracing the clamping screw on the anchor bolt, which to this extent serves as a thrust bearing
Implementation Method 2
A profile connector with a forming geometry that reshapes the first profile bar upon assembly, creating a positive locking fit and preventing twisting

AI summary
Profile connector for connecting a first and a second profile bar (3, 4), made from a light metal alloy, with a body (5) which can be accommodated in an undercut elongated groove (34) in the second profile bar (4) and has at least one bracing leg (7) for bracing against an undercut (9, 10) of the undercut elongated groove (34) of the second profile bar (4), and an anchor bolt (13) which is accommodated in a through opening (12) that is created in the body (5) and extends at right angles to a longitudinal extension of the body (5), which anchor bolt has an anchor bolt head and fixes the profile connector (1) frontally, on the first profile bar (3), and with a first clamping screw (22) accommodated in an internal threaded opening (20) provided inside the body (5) and extending at an angle to a longitudinal center line (LA) of the through opening (12), which clamping screw serves to displace the body (5) along the anchor bolt (13) away from the anchor bolt head (19) towards the first profile bar (3) by tightening the first clamping screw (22) in the internal thread of the first internal threaded opening (20), thereby bracing the first clamping screw (22) on the anchor bolt (13), wherein a forming geometry (29) is conformed and arranged on the body (5) for shaping frontally into the first profile bar (3) by tightening the first clamping screw (22) to create a positive locking connection between the body (5) and the first profile bar (3).
