Compact Hinge With Integrated Linear Damper Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture hinges with linear dampers require large installation space due to the pivoting mechanism, which is inefficient in compact designs.
Innovation Solution
A hinge design where the linear damper's housing is non-rotatably fixed to a holder on the hinge axis, allowing for a compact configuration by integrating the damper close to the lever, reducing component count and space requirements, with a cam mechanism for both closing and opening damping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the linear damper is pivotably mounted on the guide lever, then the damper can be integrated into the hinge mechanism, but the installation space required in the side part becomes large
Solution Approach 1:
The patent combines the linear damper and holder into a single integrated component, where the damper housing is formed as one piece with the holder. This merging eliminates the need for separate mounting structures and reduces the overall installation space required in the side part, while maintaining the damping function.
Solution Approach 2:
The holder is designed to serve multiple functions: it provides structural support for the hinge mechanism, mounts the linear damper, and integrates with the side part. This multi-functionality reduces the number of separate components needed and minimizes the installation space in the side part.
2Reliability
If the linear damper is fixed to a holder arranged in the side part, then damping can be achieved, but the number of components increases
Solution Approach 1:
The linear damper and holder are merged into a single integrated component formed in one piece. This eliminates the need for separate holder and damper parts, reducing the total number of components while maintaining the damping function through the integrated structure.
3Ease of manufacture
If the holder is fixed on two axes, then the linear damper can be easily installed, but the holder requires more material and space
Solution Approach 1:
The holder and damper housing are merged into a single integrated component. This eliminates the need for a separate holder structure with multiple axes, reducing the volume of stationary material required while maintaining ease of installation through the integrated design.
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
The solution enables effective damping of closing movements in a compact design, reducing the linear damper's installation space and allowing for efficient use of space within the hinge, while maintaining sufficient damping forces.
Implementation Method 1
a linear damper 10 is provided which has a pot-shaped housing 11 and a piston rod 12 which can be moved relative to the housing 11... a cam 45 is formed on one of the levers, which compresses the linear damper during a closing movement of the hinge just before reaching a closed position

AI summary
The invention relates to a hinge (1) comprising a side part (2) that can be fastened to a wall and a hinge part (3) that can be pivoted relative to the side part (2), at which hinge part a door can be attached, and comprising a linear damper (10) arranged in the side part (3) with a housing (11, 11') and a piston rod (12). The housing (11, 11') of the linear damper (10) is non-rotatably fixed in the side part (2) on at least one journal (8, 9), on which a lever (4, 5) for pivotable mounting of the hinge part (3) is mounted.
