Single-Axis Hinge With Height And Depth Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-joint hinges have limited opening angles and are difficult to adjust and attach to glass or wood materials, while single-axis hinges offer more adjustment but face challenges in attaching to thin-walled furniture and glass surfaces.
Innovation Solution
A single-axis hinge design with flange parts that can be fastened or glued to surfaces, featuring a height and depth adjustment mechanism using guide devices and fastening elements, allowing for multidimensional adjustment and compact installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multi-joint hinges are used to provide adjustment options, then the adjustment capability is improved, but the opening angle is limited and the structure becomes more complex
Solution Approach 1:
The hinge is divided into two separate pre-assembled parts: a body-side hinge part that attaches to the body and a door-side hinge part that attaches to the door leaf. This segmentation allows each part to be optimized independently, achieving multidimensional adjustment capability while maintaining a simpler overall structure compared to traditional multi-joint hinges.
2Length of moving object
If single-axis hinges with external axis are used to achieve large opening angle, then the opening angle is improved to 180-270°, but the adjustment capability is limited to two-dimensional and attachment to glass or wood materials is problematic
Solution Approach 1:
The hinge transitions from traditional two-dimensional adjustment (height and lateral) to three-dimensional adjustment by adding depth adjustment capability through the pre-assembled body-side hinge part. This allows adjustment in height, lateral position, and depth dimensions, providing comprehensive adaptability while maintaining the large opening angle characteristic of single-axis hinges.
3Ease of manufacture
If traditional hinges are attached to thin-walled furniture or glass surfaces, then the attachment is difficult and requires special frame structures
Solution Approach 1:
The hinge parts are pre-assembled with mounting components before installation. The body-side hinge part comes pre-assembled with a mounting plate and fastening elements, allowing direct attachment to glass or wood bodies without requiring pre-installed frames or complex preparation. This preliminary assembly simplifies the installation process and reduces the need for additional structural elements.

AI summary
In the case of a hinge (1) having a body hinge part (4) which can be preassembled on a body (2) and a door hinge part (6) which can be preassembled on a door leaf (3), wherein the hinge parts (4,6) are connected to each other in an articulated manner, provision is made for the body and door hinge parts (4, 6) to have respective flange parts (8, 11) fastenable onto a surface, and a height- and depth-adjusting device (10,16) is arranged in the body flange part (8) and has at least one first fastening element (17) which can be used to fix the set height and depth position of the door leaf (3) in relation to the body (2).
