Pivotable Lever Damping Coupler for Sliding Door Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sliding door systems with damper units face challenges in ensuring reliable coupling between the damper unit and damping coupler due to height offsets, leading to complex adjustments and increased guide rail width requirements, which complicates assembly and reduces adjustability.
Innovation Solution
The damping coupler is mounted on a pivotably adjustable lever, allowing for easy adjustment by an external device, even when the damper unit is already positioned, enabling a compact guide rail design and secure engagement with the damper unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the damping coupler is made taller to ensure engagement with the damper unit during adjustment, then reliable coupling is achieved, but the guide rail width increases and lateral protrusion occurs
Solution Approach 1:
The damping coupler is mounted on a pivotably adjustable lever that allows vertical positioning adjustment. This dynamic mounting enables the coupler to be positioned at the correct height to engage the damper unit without requiring excessive vertical dimension, thereby avoiding guide rail width increase while maintaining reliable coupling.
Solution Approach 2:
The height position of the damping coupler is made adjustable through the lever mechanism. By changing the vertical position parameter of the coupler, reliable engagement with the damper unit is achieved without increasing the overall height of the coupler structure itself, thus avoiding the need for a wider guide rail.
2Adaptability or versatility
If the damper unit height is adjusted to match different door leaf heights, then adaptability is improved, but height offset occurs between the damper unit and damping coupler
Solution Approach 1:
The lever providing pivotable adjustment of the damping coupler creates a dynamic height adjustment mechanism. This allows the coupler to be repositioned vertically to match the height of the damper unit attached to door leaves of different heights, maintaining precise alignment without compromising manufacturing precision.
Solution Approach 2:
The lever acts as an intermediary mechanism between the fixed guide rail and the adjustable damper unit. It mediates the height difference caused by varying door leaf heights by providing intermediate vertical positioning of the damping coupler, ensuring precise height alignment is maintained.
3Area of stationary object
If the damping coupler is positioned close to the damper unit for compact design, then guide rail width is reduced, but adjustment becomes impossible or limited
Solution Approach 1:
The pivotable lever provides dynamic adjustment capability that allows the damping coupler to be positioned close to the damper unit for compact guide rail design while still enabling full adjustment range. The lever's rotational movement allows the coupler to reach the necessary vertical positions without requiring excessive horizontal space.
Solution Approach 2:
The adjustment mechanism transitions from horizontal adjustment (which would require lateral space) to vertical adjustment through the pivotable lever. By changing the dimension of adjustment from horizontal to vertical, the guide rail width is minimized while full adjustability is maintained.
