Invisible Furniture Hinge With Internal Lateral Door Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture hinges with swing doors face issues such as increased size due to lateral and front adjustment means in the fixed part, limited damping options, and unesthetic or inefficient fixing methods, which affect production, functionality, and aesthetics.
Innovation Solution
A hinge design with lateral adjustment means in the movable part, dual deceleration devices, and a novel fixing method that eliminates protruding flanges and holes, allowing for a compact, adaptable, and aesthetically pleasing installation.
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 portion, thereby reducing the overall hinge dimension while preserving full adjustment functionality.
Solution Approach 2:
The patent utilizes the third dimension (depth/thickness of the movable part) to accommodate the lateral adjustment means. By arranging the adjustment mechanism along the longitudinal extension of the movable part, the design efficiently uses available space without increasing the hinge's external dimensions.
2Reliability
If protruding flanges and holes are used for fixing the hinge, then secure fixation is achieved, but aesthetics are compromised and space requirements increase
Solution Approach 1:
The patent extracts the protruding flanges and associated fixing holes from the hinge design. Instead of using traditional flange-based fixation, the invention employs a mounting system that eliminates these protruding elements, achieving secure fixation while maintaining clean aesthetics and reducing space requirements.
Solution Approach 2:
The patent introduces an intermediary mounting structure that mediates between the hinge and the furniture surface. This intermediary system provides secure fixation without requiring traditional flanges and holes, allowing the hinge to be fixed in a way that preserves aesthetics and minimizes space occupation.
3Device complexity
If only one deceleration device is provided, then device complexity is reduced, but damping options and adaptability are limited
Solution Approach 1:
The patent implements a universal mounting structure for deceleration devices that allows for flexible configuration. The system can accommodate one, two, or more deceleration devices depending on the specific application requirements, providing multi-functionality and adaptability while maintaining relatively simple device complexity through a standardized mounting interface.
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, customizable damping, and secure fixation without protruding elements, reducing production time and space requirements while enhancing aesthetics.
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
A hinge is described for the opening and closing of swing doors of furniture, including a fixed part shaped to be housed in a seat obtained in a horizontal plane of the furniture structure, such as a base or a top, and a movable part configured to be completely inserted into a seat obtained in a furniture door, the hinge being provided with a movement mechanism having a pair of levers or connecting rods connecting two pivot points provided on the fixed body of the hinge to two pivot points provided on the movable part to actuate the door in opening and closing, wherein lateral adjustment mechanisms are housed in the movable part of the hinge, the mechanisms being configured to perform, when the hinge is mounted, a translation of the door with respect to the furniture structure along a direction parallel to the front surface of the furniture.
