Compact Damping Device With Protruding Coupling Piece
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing damping devices for movable furniture and household appliances either require a large housing to achieve a long damping path or are not compact in design, limiting their applicability.
Innovation Solution
A damping device with a first linear damper coupled to the housing and a second linear damper between the slide and a movable coupling piece, where the coupling piece protrudes in the extended position, allowing for a long damping path while maintaining a compact design by eliminating the need for a housing that encloses the coupling piece, and utilizing guide means for precise linear guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the damping path is extended by arranging dampers in series within a housing, then the damping effect is improved, but the housing size increases significantly
Solution Approach 1:
The coupling piece is extracted from the housing enclosure and allowed to protrude in the extended position. This removes the constraint that required the housing to enclose the entire damping mechanism, enabling a long damping path while maintaining a compact housing size. The coupling piece protrudes from both the slide and the housing, creating external space for the extended damping action.
Solution Approach 2:
The damping mechanism transitions from a purely internal housing arrangement to a configuration that utilizes external space. By allowing the coupling piece to protrude from the housing in the extended position, the damping path extends into an additional dimensional space outside the housing boundaries, resolving the contradiction between long damping path and compact housing.
2Manufacturing precision
If guide means are added to ensure precise linear guidance of the coupling piece, then the guidance accuracy is improved, but the device complexity increases
Solution Approach 1:
The guide means are integrated into the existing slide mechanism rather than being added as separate external components. The slide itself provides the guiding function through its interaction with the housing, and the coupling piece is guided linearly along the slide's movement path. This merging approach ensures precise linear guidance while avoiding additional complex guiding structures.

AI summary
A damping device (1), particularly for movable furniture parts or household appliances, comprises a housing (2) to which at least one first linear damper (3) is held, which is coupled on one side to the housing (2) and on the opposite side to a movable slide (4), and at least one second linear damper (5) which is held on the slide (4) and arranged between the slide (4) and a coupling piece (6) movable relative to the slide (4), wherein the coupling piece (6) protrudes from the slide (4) and the housing (2) in the extended position. This allows the damping device to achieve a long damping stroke and a compact design.
