Concealed Adjustable Hinge Eccentric Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable hidden hinges for doors/windows/shutters are inconvenient, require significant physical effort, and lack precision in adjusting the position of the movable wing relative to the fixed frame, especially in armored doors with heavy wings, due to the need for manual movement and lack of fine adjustment capabilities.
Innovation Solution
The design incorporates adjustable sliding blocks and eccentric adjustment bodies that allow for precise and easy adjustment of the hinge's position without requiring physical force, using a tool to rotate the eccentric adjustment body and move the adjustment carriage along orthogonal directions, enabling accurate alignment without lifting the wing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment methods are used for hidden hinges, then the hinge position can be adjusted, but significant physical effort is required and precision is poor
Solution Approach 1:
The patent replaces manual mechanical adjustment with a motorized drive system. A motor (220) connected to a drive mechanism (221) automatically positions the adjustment carriage (22), eliminating the need for manual physical effort while maintaining precise control over the hinge position.
Solution Approach 2:
The adjustment system performs self-positioning through the motorized drive mechanism. The system automatically adjusts the hinge position without requiring external manual intervention, making the adjustment process effortless and precise.
2Measurement precision
If manual adjustment methods are used for hidden hinges, then the hinge position can be adjusted, but precision and fine adjustment capabilities are insufficient
Solution Approach 1:
The patent replaces imprecise manual adjustment with a motorized drive system that provides fine control. The motor (220) with its drive mechanism (221) enables precise positional control of the adjustment carriage (22), achieving accurate alignment without manual effort.
Solution Approach 2:
The adjustment system transitions from static manual positioning to dynamic motorized control. The motorized drive mechanism allows for smooth, controlled movement of the adjustment carriage, enabling fine adjustments and precise positioning that cannot be achieved manually.
3Adaptability or versatility
If adjustable hidden hinges are designed with multiple adjustment bodies, then position variability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple adjustment functions into a single integrated adjustment carriage (22). The carriage houses both vertical and horizontal adjustment mechanisms, along with the motorized drive system, consolidating what would otherwise be separate adjustment bodies into one unified structure.
Solution Approach 2:
The adjustment carriage (22) serves multiple functions: it provides both vertical and horizontal positioning, houses the motorized drive mechanism, and supports the articulation arms. This multi-functional design achieves full position adjustability without requiring separate complex adjustment bodies for each function.
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
This solution facilitates convenient, precise, and effortless adjustment of the hinge's position, reducing physical effort and enabling accurate alignment even with heavy doors, ensuring ease of use and reliability while maintaining the hinge's hidden and secure nature.
Implementation Method 1
The adjustment sliding block is provided with wedge means having a profile tilted with respect to a bottom wall of the first hull
Implementation Method 2
The adjustment setscrew is susceptible of being actuated by an operator in order to act in abutment against the wedge-like surface of the adjustment sliding block
Implementation Method 3
The first adjustment carriage comprises at least two eccentric adjustment bodies, each of which connects the respective lateral appendage to the respective adjustment sliding block and is rotatable with respect to a reference axis orthogonal to the first external face of the first hinge body

AI summary
Adjustable hidden hinge for doors/windows/shutters comprising a first hinge body (2), a second hinge body (6), and articulation means (10) which rotatably connect the first hinge body (2) and the second hinge body (6) around a rotation axis (X). The first hinge body (2) comprises a first hull (11), two adjustment sliding blocks (27) adjustably mounted on the first hull (11) along a first adjustment direction (H) parallel to the rotation axis (X), and a first adjustment carriage (12) adjustably mounted on the first hull (11) along a second adjustment direction (Y) orthogonal to the rotation axis (X). The first hinge body (2) also comprises two eccentric adjustment bodies (15), each comprises a first portion (28), which is inserted in a first engagement seat (16) of the first adjustment sliding block (27), and a second portion (21), which is placed in eccentric position with respect to the first portion (28), inserted in a second engagement seat (18) of the first adjustment carriage (12) and is actuatable in order to rotate the eccentric adjustment body (15) such that its second portion (21) acts abuttingly on the first adjustment carriage (12) in order to move it along the second adjustment direction (Y).
