Sliding Door Fitting Joint Clamping for Track Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding door fittings face challenges in achieving stable support and alignment at the joint between profiles, with existing solutions either relying on complex assembly methods or material weakening, and lacking effective compensation for steps during assembly.
Innovation Solution
A sliding door fitting with a profile connection at the joint featuring a support part and a clamping element that can be moved relative to the support part via a clamping mechanism, allowing for alignment and stabilization of profiles by transmitting high forces and minimizing space requirements, with a clamping element that can move between 0.5 mm and 4 mm to compensate for steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a profile connector is used to reinforce two profiles at a joint, then the profiles are supported on the underside of a track, but the flatness of the track in the joint area still depends on assembly precision and steps cannot be fully compensated
Solution Approach 1:
The clamping element is made movable relative to the support part via a tensioning mechanism, allowing dynamic adjustment to compensate for assembly steps and achieve proper track flatness while maintaining reliable profile support
Solution Approach 2:
The tensioning mechanism changes the position parameter of the clamping element relative to the support part, enabling the clamping element to move vertically and horizontally to compensate for joint irregularities and achieve proper track alignment
2Manufacturing precision
If a guide element is added to compensate for steps at the joint, then the roller is guided over the guide track, but the installation becomes complex and material openings cause weakening
Solution Approach 1:
The clamping element serves multiple functions: it clamps the profiles together, compensates for joint steps, and provides track support, eliminating the need for separate guide elements and reducing overall assembly complexity
Solution Approach 2:
The profile connection combines the clamping function and step compensation function into a single integrated structure, merging the previously separate profile connector and guide element into one component system
3Force
If a clamping element is made movable relative to the support part via a tensioning mechanism, then high forces can be transmitted for stabilization, but the structure becomes more complex
Solution Approach 1:
The tensioning mechanism is localized to the connection between the clamping element and support part, providing high clamping force only where needed at the joint area without complicating the entire profile structure
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
Ensures stable support and alignment of profiles at the joint, enabling effective installation and reliable operation of sliding door fittings with a compact structure and tool-free assembly, while maintaining material integrity.
Implementation Method 1
a tensioning element which is movable relative to the support part via a tensioning mechanism and which pre-tensions the two profiles towards the support part
Implementation Method 2
The tensioning element can be moved relative to the support part via the tensioning mechanism to align and level the two profiles in the area of the joint, i.e., to compensate for any step between the two profiles

AI summary
A sliding door fitting comprises two profiled elements (3a, 3b) which are connected to each other at an abutment point via a profiled-element connection (15, 50, 60) and which form at least one raceway (32, 33) for rolls or sliding pieces of a movable running part (4); the profiled-element connection (10, 50, 60) includes a support piece (11, 51, 61), which is attached to the profiled elements (3a, 3b), and a clamping element (13, 53, 63), which is movable relative to the support piece (11, 51, 61) via a clamping mechanism and which preloads the two profiled elements (3a, 3b) in the direction of the support piece (11, 51, 61). The invention also relates to a method for installing a sliding door fitting.
