Concealed Door Hinge With Segmented Supports for Shallow Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door hinges with concealed designs face challenges in achieving a compact and minimal material usage while maintaining good functional properties, particularly when installed in shallow installation depths due to constraints from door frame designs adjacent to masonry or similar structures.
Innovation Solution
The second support and fastening arrangement is divided into two separate components that are mounted directly on the door or frame surface, eliminating the need for a continuous receiving body, and are connected via the third and fourth axes, with optional centering pins and ribbing for stabilization, allowing for a compact and rigid installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a continuous receiving body is used for the second support and fastening arrangement, then structural stability is improved, but installation depth and material usage increase
Solution Approach 1:
The second support and fastening arrangement is divided into two separate support and fastening sections instead of using a continuous receiving body. These sections are connected via the third and fourth axes, allowing them to work together to provide structural stability while reducing the overall installation depth and material consumption.
2Stability of the object's composition
If a continuous receiving body is used for the second support and fastening arrangement, then structural stability is improved, but material usage increases
Solution Approach 1:
The continuous receiving body is segmented into two separate support and fastening sections. This segmentation reduces the total material required while maintaining structural stability through the distributed connection via the third and fourth axes.
Solution Approach 2:
The patent extracts the unnecessary continuous structure and replaces it with discrete sections connected through axes. This removes excess material while preserving the essential fastening and support functions.
3Volume of moving object
If separate support and fastening sections are used, then installation depth and material usage are reduced, but structural stability may worsen
Solution Approach 1:
The two separate support and fastening sections are functionally merged through their connection via the third and fourth axes. This combination allows them to collectively provide the structural stability that would otherwise require a continuous receiving body, while maintaining the benefits of reduced installation depth and material usage.

AI summary
The invention relates to a door hinge with an at least six-axis joint arrangement (3), which is connected on a first side with a first and a second axis (18, 19) extending along a vertical direction (z) to a first support and fastening arrangement (4) with a receiving body (8) and on a second side with a third and a fourth axis (20, 21) extending along the vertical direction (z). According to the invention, the second support and fastening arrangement (6) has two separate support and fastening sections (12) which are not directly connected but rather connected via the third and fourth axis (20, 21), and which are designed to be arranged with a rear fastening surface (15) directly on a door or frame surface.
