Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Concealed hinging devices for reinforced doors face challenges in correct positioning and adjustment during assembly and use, particularly due to their complexity and expense, and the need for multi-directional adjustment capabilities.
Innovation Solution
An adjustable concealed hinging device with coaxially mounted hinging elements and support means, featuring primary and additional adjustment mechanisms allowing axial, sliding, and translation adjustments, enabling easy positioning and adjustment in at least three directions perpendicular to each other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional concealed hinges are used for reinforced doors, then the door can be hinged, but the device becomes complex and expensive while lacking sufficient adjustment capability
Solution Approach 1:
The hinge is divided into two independent adjustable components: a first adjustable component for positioning along the hinge axis and a second adjustable component for positioning perpendicular to the hinge axis. This segmentation allows each component to handle one dimension of adjustment independently, providing comprehensive adaptability while keeping each individual component simple and cost-effective.
2Manufacturing precision
If conventional concealed hinges are used for reinforced doors, then the door can be hinged, but the positioning accuracy during assembly and use deteriorates
Solution Approach 1:
The hinge components are designed with pre-integrated adjustment mechanisms that enable preliminary positioning adjustments to be made during assembly. The first adjustable component allows pre-positioning along the hinge axis, while the second adjustable component enables pre-positioning perpendicular to the axis, ensuring accurate alignment before final installation.
3Adaptability or versatility
If heavy reinforced doors are hinged with conventional devices, then the door can be supported, but the adjustment capability in multiple directions is insufficient
Solution Approach 1:
The hinge system transitions from single-axis rotation to two-dimensional adjustment capability by adding the second adjustable component that operates perpendicular to the hinge axis. This dimensional expansion allows the heavy door to be positioned accurately in multiple directions while maintaining rotational support reliability through the original hinge mechanism.

AI summary
An adjustable and concealed hinging device (12) for hinging a closing element, in particular a reinforced door, with respect to a fixed element. The hinging device comprises a hinging element (21) configured to be disposed coaxially with a hinging axis (X) and mounted on a support member (22) configured to be disposed in a compartment made in the closing element. The hinging device (12) also comprises adjustment members for selectively adjusting the position of the hinging element (21) along its hinging axis (X), along a sliding direction (Y), perpendicular to the hinging axis (X), and/or along a translation direction (Z), perpendicular to both the hinging axis (X), and also to the sliding direction (Y).
