Compact Furniture Hinge Integrating Spring and Damping Mechanisms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture hinges require additional installation space and assembly work for separate spring-assisted closing and damping mechanisms, leading to a non-compact design.
Innovation Solution
Integration of a spring device and damping device into a common structural unit, allowing for a compact design where the housing parts are compressible relative to each other, enabling both locking and damping functions without the need for separate arrangements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate spring-assisted closing mechanism and damping device are arranged on the furniture hinge, then locking and damping functions are achieved, but installation space and assembly work increase
Solution Approach 1:
The patent combines the spring device and damping device into a single integrated unit that is mounted on the furniture hinge. The spring device includes a housing with a piston-cylinder arrangement where the piston rod connects to the joint lever, while the damping device is incorporated within the same housing structure. This merging eliminates the need for separate mounting of individual components, reducing installation space and simplifying assembly while maintaining both locking and damping functions.
2Reliability
If additional locking mechanism is arranged on the furniture hinge, then closing position is secured, but installation space increases
Solution Approach 1:
The damping device is nested within the housing of the spring device. The piston-cylinder arrangement of the damping device is positioned inside the spring device housing, with the piston rod extending through the housing to connect to the joint lever. This nesting arrangement allows both the spring device for securing the closing position and the damping device for controlling movement to be housed within a compact integrated structure, minimizing the installation space required on the furniture hinge.
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 solution provides a compact furniture hinge with integrated locking and damping capabilities, reducing installation space requirements and assembly complexity while ensuring reliable positioning in fully closed and open positions.
Implementation Method 1
The spring device has at least one helical spring, preferably a compression spring. Alternatively, a tension spring, a torsion spring or a leaf spring can also be used.
Implementation Method 2
The damping device has at least one, preferably hydraulic, linear damper. Such linear dampers usually include a piston-cylinder unit, with a relative movement between the cylinder and the piston being able to be damped by a damping medium, in particular a hydraulic damping medium.
