Segmented Door Hinge Structure for Low-Depth Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door hinges, particularly those with six or seven pins, face challenges in achieving a compact design with low material use while maintaining favorable functional properties, especially when installation depth is limited by adjacent structures like masonry.
Innovation Solution
The second support and fastening system is divided into two separate sections, each attached directly to the door or frame surface via third and fourth pins, eliminating the need for a continuous receiving body, and utilizing corrugations and centering pins for stabilization, allowing a compact and stable installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a continuous receiving body is used for the support and fastening system, then structural stability is improved, but installation depth and material use increase
Solution Approach 1:
The second support and fastening system is divided into two separate support and fastening sections (12) that are not directly connected but are linked via the third and fourth pins. This segmentation eliminates the need for a continuous receiving body, reducing installation depth while maintaining structural stability through the pin connections between sections.
2Stability of the object's composition
If a continuous receiving body is used for the support and fastening system, then structural stability is improved, but material use increases
Solution Approach 1:
The support and fastening system is segmented into separate sections (12) that are connected via pins rather than requiring a continuous receiving body. This reduces the total material quantity needed while maintaining structural stability through the distributed pin connections that provide load paths between sections.
3Length of stationary object
If the hinge system is designed for compact installation, then installation depth is reduced, but stability may be compromised
Solution Approach 1:
The third and fourth pins serve as intermediaries that connect the separate support and fastening sections (12) to each other and to the hinge system. These pin intermediaries transmit forces and maintain stability between the segmented sections, enabling compact installation without compromising structural integrity.
Solution Approach 2:
The separate support and fastening sections (12) are configured to be arranged with their rear fastening surfaces directly on the door or frame surface, allowing them to self-stabilize through direct surface contact. This self-service stabilization mechanism eliminates the need for additional connecting structures that would increase installation depth.
4Ease of manufacture
If a conventional support and fastening system is used, then ease of manufacture is improved, but concealment and compactness are reduced
Solution Approach 1:
The support and fastening system is segmented into separate sections (12) with rear fastening surfaces that can be directly mounted on flat door or frame surfaces. This segmentation enables a compact, concealed design where the hinge components are positioned closer to the surface, improving concealment while maintaining manufacturing simplicity through standardized fastening interfaces.

AI summary
Disclosed is a door hinge having an at least six-pin hinge system, which is connected, on a first side, by way of a first and a second pin extending along a vertical direction to a first support and fastening system with a receiving body and, on a second side, by way of a third and a fourth pin extending along the vertical direction to a second support and fastening system. The second support and fastening system has two separate support and fastening sections which are not connected directly but via the third and fourth pins and which are configured to be arranged with a rear fastening surface directly on a door or frame surface.
