Invisible Furniture Hinge With Movable-Part Door Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture hinges for swing doors are limited by the presence of adjustment means in the fixed part, which increase the hinge's size, require additional flanges and holes for installation, and lack adaptability in damping options.
Innovation Solution
A hinge design with lateral adjustment means in the movable part, allowing for a compact structure, dual deceleration options, and a novel installation method without flanges or protruding holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lateral adjustment means are housed in the fixed part of the hinge, then adjustment functionality is provided, but the overall dimension of the hinge increases and space for functional elements is reduced
Solution Approach 1:
The patent inverts the conventional arrangement by moving the lateral adjustment means from the fixed part to the movable part. This inversion allows the adjustment mechanism to be housed in the previously underutilized movable part, reducing the fixed part's dimensions while maintaining full adjustment functionality. The movable part's internal cavity provides sufficient space for the adjustment mechanism without increasing the overall hinge footprint.
2Adaptability or versatility
If adjustment means are provided in the fixed part, then door position adjustment is enabled, but production time and milling time increase
Solution Approach 1:
By inverting the location of the adjustment means from the fixed part to the movable part, the patent eliminates the need for complex flange structures and multiple holes in the fixed part. This simplification reduces the number of machining operations required for the fixed part, thereby decreasing production time while preserving the door position adjustment capability through the movable part's adjustment mechanism.
3Adaptability or versatility
If multiple adjustment means are housed in the fixed part, then comprehensive adjustment capability is achieved, but the hinge structure becomes more complex
Solution Approach 1:
The patent consolidates the adjustment means into the movable part, which has sufficient internal cavity space to accommodate all necessary adjustment mechanisms. This consolidation simplifies the fixed part structure by eliminating the need for multiple adjustment mechanisms and associated flanges and holes, thereby reducing overall structural complexity while maintaining comprehensive adjustment capability across all three axes.
4Reliability
If flanges and holes are provided for installation, then secure mounting is achieved, but the fixed part's dimension and space requirements increase
Solution Approach 1:
The patent extracts the flange structure and associated mounting holes from the fixed part, eliminating these elements entirely. Instead, the fixed part is designed as a flat plate that mounts directly to the furniture surface without requiring protruding flanges. The mounting security is maintained through direct fixation to the furniture surface, while the space previously occupied by flanges and holes is freed up for other functional elements.
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
The hinge achieves efficient adjustment along three axes, reduces production time, and provides customizable damping, while ensuring secure and aesthetic installation.
Implementation Method 1
a spring, which is loaded during the opening movement of the door and exerts a thrust force on the door in the final closing phase of the latter
Implementation Method 2
At least one deceleration device is also generally provided in the hinge, which in the following, for convenience, will also be referred to as shock absorber or damper, apt to guarantee a braking effect of the hinge during its closure

AI summary
Hinge (10; 110) for swing doors of furniture, comprising a fixed part (11; 111) to be housed in a seat obtained in a horizontal plane of the structure of a piece of furniture, and a movable part (12; 112) to be inserted in a seat obtained in a door of the piece of furniture, said hinge being provided with a movement mechanism comprising a pair of connecting rods (18, 19: 118, 119) connecting said fixed part (11; 111) to said movable part (12; 112), wherein said movable part (12; 112) houses means for vertical adjustment (31) of the position of the door with respect to the furniture, the actuation of which causes a translation of the movable part (12; 112) with respect to the fixed part (11; 111) along a vertical direction (Y), said movable part (12; 112) further comprising a first body (12'), in which said vertical adjustment means of the door are housed and to which the connecting rods are hinged, and a second body (12") intended to be fixed to said seat obtained in the furniture door, between said first and second body being arranged means for lateral adjustment (25; 125) of the position of the door, the operation of which causes a sliding of said second body (12") with respect to said first body (12') and therefore a horizontal translation of the door with respect to the furniture structure along a direction (X) parallel to the front surface of the furniture.
