Compact Furniture Hinge Damping Mechanism Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture hinges with damping mechanisms face challenges in compact design and increased dimensions when incorporating damping members within the hinge body, which is undesirable for manufacturers and consumers.
Innovation Solution
A compact damping mechanism is integrated within the hinge body, featuring a damper and housing that slides within the hinge body, with the damper's cylinder supported by a pin, allowing for effective damping of door closure without increasing the hinge's dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a damping member is provided within the hinge body, then the damping function is achieved, but the hinge dimensions increase
Solution Approach 1:
The damping mechanism is nested within the hinge body structure. The housing is received within the hinge body, and the damper is received within the housing, creating a compact nested arrangement where the cylinder body extends from the housing and is supported by a pin in the hinge body, achieving damping functionality without increasing overall hinge dimensions
Solution Approach 2:
The damping mechanism utilizes the articulation movement dimension of the hinge cup relative to the hinge body. The housing is slidebly guided within the hinge body by a linkage member, and the cylinder body is supported by a pin, allowing the damping action to occur along the articulation path rather than requiring additional space in traditional dimensions
2Reliability
If a damping member is provided within the hinge body, then the damping function is achieved, but the device complexity increases
Solution Approach 1:
The hinge body serves multiple functions: it provides the structural mounting for the hinge mechanism and simultaneously houses the damping mechanism. The linkage member both connects the hinge cup to the hinge body and provides sliding guidance for the housing. The pin both supports the cylinder body and serves as a pivot point, reducing the need for separate dedicated components
Solution Approach 2:
The damping mechanism components are merged with the hinge body structure. The housing is integrated within the hinge body, the linkage member combines connection and guidance functions, and the pin serves dual purposes as both support and pivot, thereby reducing overall device complexity while maintaining damping functionality

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a compact and effective damping mechanism that reduces noise and wear during door closure, maintaining the hinge's compact size while ensuring a smooth and controlled closing action.
Implementation Method 1

AI summary
The present invention relates to a furniture hinge having a damping function which comprises a first bracket adapted to be secured to a furniture door; a second bracket adapted to be secured to a furniture cabin by a mounting plate; a first linkage member and a second linkage member which are connected between the first bracket and the second bracket in a pivotable manner; a torsion spring which is fitted around a first pin for urging the furniture door to move from an opened position to a closed position relative to the furniture cabin; a damping mechanism having a damper and a housing being slidebly holded within the second bracket and supported by the first linkage member; the damper having a cylinder body which is partially extended out from the housing and abuts against to a second pin wherein the damping mechanism is configured such that when the furniture door is closed onto the furniture cabin, the first linkage member drives the housing over the cylinder body.
