Door Hinge With Three-Axis Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinges for doors or windows made with section bar elements lack simplicity, efficiency, and cost-effectiveness, and do not allow easy and rapid adjustment of the mobile element's position with respect to the fixed structural element in three perpendicular directions without disassembly.
Innovation Solution
A hinge design featuring two hinging units connected by a pivoting member with adjustment means, including a pivoting element, a connection element with sliding blocks and grooves, and eccentric elements, allowing for adjustments along three perpendicular directions without disassembly, using a C-shaped support element and L-shaped connection plates for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a hinge for doors or windows made with section bar elements is designed to be simple, efficient, and inexpensive, then the manufacturing cost and assembly time are reduced, but the ability to adjust the mobile element's position in three perpendicular directions without disassembly is lost
Solution Approach 1:
The hinge incorporates nested adjustment mechanisms where the first adjustment means (for pivoting axis direction) is integrated within the second adjustment means (for direction perpendicular to pivoting axis), which is in turn integrated within the third adjustment means (for direction perpendicular to both previous directions). This nested structure allows multiple adjustment functions to be compactly combined in a simple and cost-effective manner.
Solution Approach 2:
The hinge employs dynamic adjustment mechanisms that allow continuous modification of the mobile element's position during use. The adjustment means are designed to enable rapid, continuous adjustment without discrete steps or requiring disassembly, making the system adaptable while maintaining structural simplicity.
2Adaptability or versatility
If adjustment means are added to allow selective adjustment of the mobile element's position in three perpendicular directions, then adaptability and versatility are improved, but device complexity increases
Solution Approach 1:
The hinge merges three separate adjustment functions into an integrated system where the first adjustment means, second adjustment means, and third adjustment means work together as a unified mechanism. This merging reduces overall complexity compared to having three independent adjustment systems, while still providing full three-directional adjustability.
Solution Approach 2:
The adjustment means are designed with multi-functionality where each adjustment mechanism serves multiple purposes: the first adjustment means adjusts position along the pivoting axis, the second adjusts position perpendicular to the pivoting axis, and the third adjusts position perpendicular to both previous directions. This universal design reduces the need for separate specialized components for each adjustment direction.
3Productivity
If adjustment mechanisms are designed to allow rapid and continuous adjustment without disassembly, then ease of operation and productivity are improved, but device complexity increases
Solution Approach 1:
The hinge incorporates preliminary action mechanisms where the adjustment means are pre-configured to enable immediate adjustment upon activation. The first adjustment means, second adjustment means, and third adjustment means are designed to be readily accessible and operable without preliminary disassembly steps, allowing rapid adjustment during installation and use.
Solution Approach 2:
The adjustment mechanisms are designed to be self-contained and self-operating, where each adjustment means can be operated independently without requiring external tools or disassembly of other components. This self-service design enables rapid, continuous adjustment while maintaining relatively simple device architecture.

AI summary
A hinge (10) for doors or windows (11) made using section bar elements (13, 15) to hinge a mobile element (12) of the door or window (11) with respect to a fixed structural element (14) of the door or window (11). The hinge (10) comprises a first hinging unit (16) configured to be attached to the fixed structural element (14), a second hinging unit (17) configured to be attached to the mobile element (12), and a pivoting member configured to articulate the two hinging units (16, 17) with respect to each other along a pivoting axis (X). The hinge (10) is also provided with adjustment means that allow to selectively move the mobile element (12) of the door or window (11) with respect to the fixed structural element (14) parallel to the pivoting axis (X) and in two directions perpendicular with respect both to each other and also to the pivoting axis (X).
