Adjustable Corner Fitting for Non-Standard Door Axes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional corner fittings for door elements, particularly glass doors, are limited in their ability to mount door elements on non-standard centers of rotation and axes, as the connecting element is typically integral and only suitable for standardized mounting.
Innovation Solution
A corner fitting design featuring a first and second fitting element with a displaceable holding element and a connecting element, incorporating an attaching mechanism that can transition between a released and fixing condition, allowing for infinitely variable adjustment and secure positioning of the door element on non-standard centers of rotation and axes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the connecting element is configured integrally with the corner fitting, then the mounting of door elements on standardized centers of rotation and axes is guaranteed, but the ability to mount on non-standard centers of rotation and axes is limited
Solution Approach 1:
The corner fitting is divided into separate functional components: fitting elements for clamping the door element, a holding element for positioning, and a connecting element for supporting on the center of rotation. This segmentation allows each component to be optimized independently, enabling adjustment of the holding element relative to the fitting elements while maintaining secure clamping.
Solution Approach 2:
The holding element is designed to be displaceable relative to the fitting elements through an attaching mechanism that can transition between released and fixing conditions. This dynamic capability allows the corner fitting to adapt to non-standard centers of rotation and axes by adjusting the position of the holding element, while maintaining stable support when fixed.
2Adaptability or versatility
If the holding element is made displaceable for adjustment, then infinitely variable adjustment of the door element position is enabled, but the stability of the mounted door element may be compromised
Solution Approach 1:
The holding element incorporates an attaching mechanism with two distinct states: a released condition allowing infinite displacement for adjustment, and a fixing condition providing stable non-positive and/or positive connection. This dynamic design enables the system to transition between adaptability and stability as needed.
Solution Approach 2:
The attaching mechanism changes the connection parameter from movable to fixed by transitioning between released and fixing conditions. In the fixing condition, the holding element is non-positively and/or positively connected to the fitting element, transforming the parameter of displacement to zero while maintaining the adjustment capability through the mechanism's design.
3Adaptability or versatility
If the attaching mechanism is added to enable adjustment, then non-standard center mounting becomes possible, but the device complexity increases
Solution Approach 1:
The holding element and connecting element are merged into a single operative unit that works together through the attaching mechanism. This combining reduces the effective number of independent components while maintaining the functionality of separate elements, as the holding element's displacement directly controls the connecting element's position relative to the door element.

AI summary
An adjustable corner fitting for a door element is disposed on a center of rotation and/or an axis, including first and second fitting elements, which, at least sectionwise, each include a locating portion for the abutment against the door element and are interconnectable while restraining the door element.A restraining area is formed between the two fitting elements, into which the door element is insertable, and the fitting elements are formed such that a holding element is disposed between both fitting elements, which is displaceable in relation to the fitting elements. A holding element is in operative connection with the connecting element, which serves for supporting the door element on the center of rotation and/or the axis. An attaching mechanism is incorporated at least at the holding element and at least at the connecting element, which is transferable between a released condition and a fixing condition, wherein, in the released condition, the holding element is displaceable at the fitting elements. In the fixing condition, it is non-positively and/or positively attached at least to one fitting element.
