Furniture Damper with Movable Component Relocation for Extended Stroke
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional damping devices face challenges in accommodating limited space, particularly during the end-of-travel damping of drawers during their opening movement, where the damping function is only triggered when the drawer reaches its open position, making it difficult to effectively dampen the movement due to spatial constraints.
Innovation Solution
The damping device features a first damper component that is movably mounted on a holder with stop means, allowing it to be displaced from a standby position to a working position, where it can initiate the damping function upon impact with a second damper component, enabling a larger damping stroke without obstructing the drawer's full extension, and includes a driver element that moves the first damper component from the ready to the working position, allowing the damping function to be triggered before the drawer reaches its fully open position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the damping device is located in the area of the drawer opening to trigger end-of-travel damping, then the damping function is activated at the correct position, but the available space for accommodating the damping device is severely limited
Solution Approach 1:
The damping device employs a dynamic positioning mechanism where the first damper component can be displaced from a standby position to a working position. The driver element, actuated by the drawer's movement, dynamically repositions the damper component only when needed for damping, allowing the device to adapt to spatial constraints while ensuring reliable damping activation at the correct drawer position
Solution Approach 2:
The damping device is divided into separable components: a first damper component that can be independently positioned and a second damper component that remains stationary. This segmentation allows the first component to be relocated from standby to working position, optimizing space utilization while maintaining the integrity of the damping function
2Length of moving object
If the first damper component is relocated from standby to working position before damping, then a larger damping stroke is available, but the device complexity increases due to the relocation mechanism
Solution Approach 1:
The relocation function and damping function are merged into a single mechanical interaction. The driver element, which is naturally present in the drawer assembly, serves dual purposes: it both triggers the damping sequence and performs the relocation of the first damper component. This merging eliminates the need for separate relocation actuators, reducing overall device complexity while achieving the desired larger damping stroke
Solution Approach 2:
The drawer's own movement serves to reposition the damping device. As the drawer opens and the driver element moves, it automatically displaces the first damper component from standby to working position without requiring external control systems or additional energy input. The system uses the drawer's motion itself to prepare the damping mechanism, simplifying the overall control architecture

Function Achieved in This Case
This design allows for reliable and functional damping in cramped conditions, enabling a larger damping stroke while allowing the drawer to be extended almost completely, effectively addressing the spatial limitations and improving the field of application for damping devices.
Implementation Method 1
a driver element (46) which, upon opening, moves the first damper component (30) from the ready position (32) into the working position (33), in which the driver element (46) impacts the second damper component (31)
Implementation Method 2
a damper piston (44) which is accommodated in a damper housing (45) in a linearly displaceable manner and generates a damping function
