Adjustable Corner Fitting for Flush Door Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional corner fittings for door elements are limited to two fixed centers of rotation or axes, specifically 55 mm and 65 mm, making it impossible to align double-action doors flush on non-standard centers or axes, leading to installation challenges and potential misalignment issues.
Innovation Solution
A corner fitting system comprising two fitting elements with a displaceable holding element and connecting element, allowing for adjustable alignment between 50 mm and 80 mm, enabling flush alignment on non-standard centers or axes through an infinitely variable mechanism, which includes a free space guide and an attaching mechanism for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid connecting element with predetermined position is used, then the structure is simple and stable, but the adaptability to different centers of rotation is limited
Solution Approach 1:
The patent applies the dynamics principle by transforming the rigid, fixed-position connecting element into a displaceable holding element that can move along the fitting elements. This allows the connecting element to be positioned at different locations to accommodate various centers of rotation, making the fitting device adaptable to different door configurations while maintaining structural stability through the constraint mechanism.
Solution Approach 2:
The patent segments the connecting element into a holding element that can be separately displaced and positioned relative to the fitting elements. This segmentation allows independent adjustment of the connecting element's position along the fitting elements, enabling adaptation to different centers of rotation without redesigning the entire fitting device.
2Manufacturing precision
If fixed center of rotation positions are specified, then manufacturing and installation are simplified, but alignment precision for non-standard doors is compromised
Solution Approach 1:
The patent applies parameter changes by allowing the position parameter of the connecting element to be variable rather than fixed. The holding element can be displaced along the fitting elements to change the center of rotation position according to the specific door requirements, achieving precise alignment for both standard and non-standard doors while maintaining ease of installation through the simple displacement and attachment mechanism.
3Adaptability or versatility
If a displaceable holding element is introduced, then adaptability to different centers of rotation is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing the holding element to perform multiple functions: it serves as both a connector and a displacement mechanism. The same holding element that connects the door to the fitting elements also provides the adaptability to different centers of rotation through its displaceable nature, eliminating the need for separate adjustment mechanisms and reducing overall device complexity.
4Ease of operation
If the connecting element is made displaceable, then ease of installation and adjustment is improved, but the stability and rigidity of the door element may be compromised
Solution Approach 1:
The patent applies preliminary action by providing guide structures on the fitting elements that predefine the displacement path and constraints for the holding element. This preliminary guidance ensures that the holding element can be easily displaced during installation while automatically maintaining proper alignment and stability, eliminating the need for complex real-time adjustment mechanisms.

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 the two fitting elements, which is displaceable in relation to the fitting elements. A holding element is non-positively and/or positively connectable to at least one fitting element, wherein the 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.
