Sliding Door Damper Adjustment for Sloped Rail Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of sliding doors is complicated by imprecise conditions such as sloping walls and ceilings, which can lead to the damping or retraction function being impaired due to inadequate engagement between the coupler and the gripping part, causing the door to bounce off or not reach its closed position accurately.
Innovation Solution
A support system for sliding doors with an adjustable damper unit and coupler that allows for horizontal and potentially orthogonal adjustments via a screw connection and spacer plates, ensuring proper alignment and engagement even in imprecise installation conditions, such as tilted running rails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the running rail is mounted on a sloping wall or ceiling, then the sliding door can be installed in imprecise installation conditions, but the coupler does not sufficiently engage in the gripping part of the damper unit, impairing the damping or retraction function
Solution Approach 1:
The coupler is designed with adjustability in its positioning relative to the damper unit, allowing it to adapt dynamically to different installation conditions. The coupler can be adjusted in the longitudinal direction of the running rail to ensure sufficient engagement with the gripping part even when the running rail is tilted or improperly mounted.
Solution Approach 2:
The position of the coupler can be changed by adjusting its mounting parameters, such as the distance from the door leaf or the horizontal position relative to the damper unit. This allows compensation for installation errors in the running rail alignment.
2Reliability
If the coupler and gripping part are adjusted to ensure proper engagement, then the damping function works reliably, but the installation process becomes more complex
Solution Approach 1:
The adjustment system is divided into simple, discrete adjustment elements that can be independently modified. The coupler's position can be adjusted through simple mechanical means such as repositioning mounting holes or using adjustable fasteners, rather than requiring complex adjustment mechanisms.
3Power
If the coupler is positioned to engage the gripping part, then the damper unit can brake the closing movement, but the door leaf may bounce off the end stop and fall back
Solution Approach 1:
The damper unit incorporates a retraction function that actively pulls the door leaf into the closed position after braking the closing movement. This dynamic retraction ensures the door leaf reaches and maintains its closed position without bouncing back, complementing the braking function.
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 adjustment system simplifies the installation process by allowing for precise coordination of the coupler and gripping part, ensuring reliable interaction and accurate closure of the sliding door without requiring adaptation of the running rail to the tilting angle, thus facilitating easier and more reliable operation.
Implementation Method 1
The damper absorbs the kinetic energy of the door leaf during the closing movement of the sliding door
Implementation Method 2
a spring which pulls the force part of the damper in the direction of the end position of the damper
