Integrated Hinge Door Device with Torsion Spring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional slide hinges face challenges in providing a necessary catch or assist function, especially with heavy doors or upwardly opening doors, due to limited space for springs, resulting in poor appearance and mounting issues when combined with separate mechanical parts.
Innovation Solution
A door device that integrates with the hinge, featuring a base attached to the hinge's first part and incorporating a biasing mechanism, such as a torsion spring, to enhance the catch and assist functions while allowing for adjustable torque application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a spring is arranged in the limited space of the slide hinge, then the hinge structure is compact, but the spring force cannot be increased sufficiently
Solution Approach 1:
The patent extends the spring arrangement from the two-dimensional plane of the hinge to a three-dimensional configuration that projects beyond the hinge body. The support plate and link structure create additional spatial dimensions for spring placement, allowing the spring to extend in a direction perpendicular to the hinge's main plane, thereby increasing spring force without compromising hinge compactness
Solution Approach 2:
The patent nests multiple functional components within each other: the spring is positioned between the link and support plate, which are themselves integrated into the hinge structure. This nested arrangement allows the spring to occupy space that would otherwise be unused, maximizing the utilization of available volume while maintaining sufficient spring force
2Reliability
If a door device is used in combination with the slide hinge, then the necessary catch function and assist function can be ensured, but the appearance becomes poor and mounting becomes troublesome
Solution Approach 1:
The patent merges the door device with the slide hinge into a single integrated structure. The support plate serves dual purposes: it provides structural support for the spring mechanism while also functioning as part of the hinge assembly. This consolidation eliminates the need for separate mounting brackets or additional mechanical components, thereby ensuring reliable catch and assist functions while maintaining clean appearance and simplifying installation
Solution Approach 2:
The support plate is designed as a multi-functional component that simultaneously serves as a structural element of the hinge, a mounting surface for the spring, and a linkage element connecting to the link. This universal component performs multiple functions that would traditionally require separate parts, reducing overall device complexity while maintaining functional reliability

Function Achieved in This Case
The integrated door device provides a sharp impression, ensures necessary catch and assist functions, and widens the selection range of biasing means, ensuring effective torque application for both closing and opening operations.
Implementation Method 1
The spring is, for example, a torsion spring, and is provided between the first part and the link or between the second part and the link for applying torque to the link
