Furniture Hinge Damping Adjustment for Variable Door Weights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture hinges lack an independent and easily accessible mechanism for adjusting damping force and position, making them unsuitable for doors of varying weights and sizes, and often involve complex mechanisms that increase failure risks.
Innovation Solution
A furniture hinge with a damping adjustment mechanism that allows independent adjustment of damping force and position through a lever arm, using a sliding element and adjustment piece accessible via a screwdriver, enabling compatibility with different door weights and sizes while minimizing failure risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex adjustment mechanism is used to enable damping adjustment at different positions, then damping force and position can be adjusted, but device complexity increases and failure risks increase
Solution Approach 1:
The adjustment mechanism is segmented into independent functional components: a damping adjustment lever that can be independently operated from the power adjustment mechanism. This allows the damping function to be adjusted separately without affecting other hinge functions, reducing overall system complexity while maintaining adjustability.
Solution Approach 2:
The damping adjustment capability is extracted as a separate, accessible function from the main hinge mechanism. The damping adjustment lever is positioned to be easily accessible and operable independently, separating the damping adjustment task from the complex power adjustment mechanism.
2Device complexity
If the adjustment mechanism is made compact and integrated, then device complexity is reduced, but accessibility for adjustment becomes difficult
Solution Approach 1:
The damping adjustment lever is positioned in a different spatial dimension or location that is easily accessible to the user, separate from the main hinge body. This allows the adjustment function to be reached and operated without disassembly, even though the internal mechanism remains integrated and compact.
3Ease of operation
If damping adjustment is made independent from power adjustment, then ease of operation improves, but device complexity increases
Solution Approach 1:
The adjustment system is segmented into two independent control levers: a power adjustment lever and a damping adjustment lever. Each lever controls a specific function independently, allowing users to adjust damping without affecting power settings and vice versa, improving operational ease while maintaining manageable complexity through functional separation.

AI summary
The present invention relates to a furniture hinge that is suited for changing damping course of the furniture door in the closing direction. The inventive furniture hinge comprises; a housing; a hinge arm that is connected to the furniture door from the one end and connected to said housing in an axially rotatable manner from the other end by means of a first rotating pin; a power unit having at least one spring that creates force on said hinge arm, and that is connected between a lever arm that is capable of accommodating a power adjustment thereon and a third rotating pin in an axially rotatable manner; a movement arm that is connected to said hinge arm from one end in an axially rotatable manner, that is connected to said lever arm from the other end in an axially rotatable manner, and that enables the power transmission between said power unit and hinge arm; a damping element located on said lever arm for damping the furniture door that is being closed over the furniture body; and a damping adjustment on said lever arm for the purpose of changing the position of a cylinder belonging to the damping element with respect to the lever arm.
