Furniture Hinge Damper Housing with Integrated Spring Seat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture hinges with dampers integrated into the hinge boss suffer from dust accumulation, increased assembly complexity, and higher construction costs due to additional components, while maintaining a continuous metal surface is challenging.
Innovation Solution
The housing serves as a dual functional unit, incorporating a spring receptacle to house the damper and spring, simplifying assembly by eliminating the need for additional mountings and allowing the housing, damper, and spring to be pre-assembled and fastened as a unit to the hinge boss, with the spring being securely fastened via a groove or plug-fit mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the damper is disposed entirely within the hinge boss, then the furniture hinge has a compact structure, but gaps are formed between the housing and hinge boss where dust accumulates and the continuous metal surface is disrupted
Solution Approach 1:
The housing containing the damper is extracted from the interior of the hinge boss and positioned on its external side. This eliminates the gaps that would form between the housing and hinge boss, preventing dust accumulation while maintaining the compact structure through external mounting.
Solution Approach 2:
The housing serves as an intermediary component that mounts on the external side of the hinge boss, providing a interface that maintains the continuous metal surface appearance while accommodating the damper. The housing acts as a mediator between the aesthetic requirements of the metal surface and the functional requirements of dust-proofing.
2Ease of manufacture
If the housing is made of plastic, then the furniture hinge can be produced cost-effectively, but the continuous metal surface of the hinge boss is disrupted and mechanical stability is reduced
Solution Approach 1:
The furniture hinge is segmented into distinct functional components: the hinge boss made of metal for structural strength and continuity, and the housing made of plastic for cost-effective production of the damper assembly. This segmentation allows each material to be used where it provides the most benefit.
Solution Approach 2:
The housing performs multiple functions: it accommodates the damper, provides a mounting interface on the external side of the hinge boss, and maintains the continuous metal surface appearance. By consolidating these functions in a single plastic component, manufacturing costs are reduced while the metal hinge boss retains its structural integrity.
3Adaptability or versatility
If additional components like cover and separate spring mounting are added, then the furniture hinge can accommodate all components, but the construction costs increase and assembly complexity increases
Solution Approach 1:
The spring mounting function is merged with the housing by integrating a spring receptacle directly into the housing structure. This eliminates the need for separate spring mountings and covers, reducing the number of components and simplifying assembly while maintaining the ability to accommodate all necessary components.
Solution Approach 2:
The housing is designed as a multi-functional component that simultaneously accommodates the damper, provides structural support, and includes an integrated spring receptacle. This universal design consolidates multiple functions into a single component, reducing assembly complexity and construction costs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration reduces assembly complexity, maintains a clear and easily cleanable metal surface, and lowers production costs by integrating the spring receptacle into the housing, ensuring effective damping and a unified, high-quality appearance.
Implementation Method 1
a damper (60) is disposed in a housing (50)
Implementation Method 2
a spring (24) is operatively connected to the hinge boss (30) and to the detent element (21) or to the articulated lever (23)

AI summary
The invention relates to a furniture hinge comprising a stop element and a hinge cup which is pivotally connected to said stop element by means of an articulated lever, a damper being arranged in a housing, said housing being connected to the hinge cup by means of securing means, and a spring being functionally connected to the hinge cup and the stop element or the articulated lever. According to the invention, the housing comprises a spring seat by means of which said spring is secured to the housing. This achieves a damped, compact furniture hinge which has a spring to support at least the closing action, and which is easy to mount.
