Adjustable Hinge With Nested Mounting Part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinges for door or window rotation adjustment lack comprehensive three-dimensional adjustment capabilities, are dependent on installer skill, and have limited adjustment options due to fixed hinge pin positions and limited screw fastening options, making them difficult to adjust and re-adjust post-installation.
Innovation Solution
A compact, nested hinge design with a displaceable mounting part and self-locking mechanism, featuring a threaded pin and bolt system for fine adjustments, allowing three-dimensional alignment and easy readjustment, with a narrower holder for transverse adjustment and a bolt system for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hinge uses fixed hinge pin positions with limited fastening holes, then the hinge structure remains simple, but the adjustment options become very limited and dependent on installer skill
Solution Approach 1:
The hinge transforms from a static structure with fixed adjustment points to a dynamic system where the mounting part can be continuously repositioned along the first hinge part. The displaceable mounting part with self-locking capability allows the hinge to adapt to different positioning requirements while maintaining structural simplicity.
Solution Approach 2:
The hinge is divided into distinct functional components: the first hinge part, the displaceable mounting part, and the self-locking mechanism. This segmentation allows each component to perform its specific function independently, enabling complex adjustment capabilities without proportionally increasing overall structural complexity.
2Adaptability or versatility
If a hinge allows three-dimensional adjustment with multiple hinge parts, then the adjustment capability improves, but the hinge dimensions increase due to nested design requirements
Solution Approach 1:
The mounting part is nested within the first hinge part, allowing it to move along the length of the first hinge part without requiring additional external space. This nested configuration enables three-dimensional adjustment capability while keeping the overall hinge compact and avoiding excessive dimension increases.
3Measurement precision
If the holder is made narrower for transverse adjustment, then the adjustment precision improves, but the space for screw fastening decreases
Solution Approach 1:
The solution moves the fastening function to a different dimension by providing fastening holes in the first hinge part that extend beyond the narrower holder section. This allows the holder to be narrow for precise transverse adjustment while the fastening holes provide sufficient area for secure screw fastening in a different spatial location.

AI summary
In a hinge (1) for the rotatable holding of a door (2) on a frame, a respective first hinge part (4) is provided for fitting at the upper and at the lower end of the door (2), and an associated, second hinge part (5) which is fastened to the frame is respectively provided. One of the hinge parts (5) has a hinge pin (6) which engages in a hole (7) in the other hinge part (4). The hinge pin (6) and the hinge-pin-receiving hole (7) in the two hinge parts (4, 5) form the axis of rotation (8) of the door (2) with respect to the frame. The hole (7) which receives the hinge pin (6) is formed in a mounting part (12) which is displaceable in the first hinge part (4), and said mounting part (12) is guided in an infinitely adjustable manner on the first hinge part (4) and is fixable thereon in the desired position in a self-locking manner. The mounting part (12) is inserted into a recess (13) in the first hinge part (4) which is designed in the manner of a housing, wherein a basic body (14) of the mounting part (12) is held displaceably, but fixedly in a self-locking manner, in a guide (15). A displaceable holder having the hole (7) for the hinge pin (6) is inserted into an opening formed on the lower side of the basic body (14).
