Two-Way Soft Closing Device for Sliding Doors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional soft closing devices for sliding doors are limited by their single-sided functionality, leading to noise, potential accidents, and installation complexities, particularly when dealing with non-perpendicular door alignments and variable door sizes, and require extensive repair processes that damage interior decorations.
Innovation Solution
A two-way soft closing device with adjustable triggers and a sliding door track system that includes roller carriers and a soft closing assembly with a damper, spring, and tracking assemblies, allowing for bi-directional soft closing and easy gap adjustment, preventing collisions and injuries while facilitating easier installation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-sided soft closing device is used to prevent door panel collision, then collision prevention is improved, but the device cannot handle non-perpendicular alignments and creates installation complexity
Solution Approach 1:
The soft closing device is divided into two independent soft closing assemblies, each mounted on opposite sides of the sliding door track. Each assembly independently handles soft closing in one direction, allowing the system to manage non-perpendicular alignments and variable door sizes without increasing overall system complexity.
Solution Approach 2:
Each soft closing assembly is designed with universal adaptability to handle various door alignments and sizes. The adjustable trigger mechanism and resilient spring design allow the same assembly structure to function effectively in different installation scenarios, reducing installation complexity.
2Device complexity
If the soft closing activation trigger is fixed in position, then the structure is simple, but it cannot adjust closing distance for different door requirements
Solution Approach 1:
The soft closing activation trigger is designed as a movable component that can be adjusted along the sliding door track. This dynamic positioning capability allows the trigger to be set at different locations to achieve various closing distances, while the overall structure remains simple and easy to adjust.
3Ease of operation
If the resilient spring force is increased to overcome friction, then door movement is improved, but it causes gap formation between door panel and wall
Solution Approach 1:
The resilient spring force is optimized to provide sufficient power to overcome friction between the track and wheels, while the adjustable trigger position allows precise control of the closing distance. This parameter optimization prevents gap formation between the door panel and wall while maintaining smooth door movement.
4Stability of the object's composition
If the soft closing device is mounted firmly in the track, then stability is improved, but repair and maintenance require track removal damaging interior decorations
Solution Approach 1:
The soft closing assembly is designed as a separate, self-contained unit that can be independently removed from the sliding door track. This segmentation allows the assembly to be firmly mounted for stability during operation, while enabling easy removal for repair and maintenance without requiring track removal or damaging interior decorations.
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 two-way soft closing device effectively absorbs collisions, reduces noise, prevents injuries from fast-moving doors, and simplifies installation and repair by allowing for adjustable closing distances and easy maintenance without damaging interior decorations.
Implementation Method 1
The inconsistency in the construction site will increase the resilience of the soft-closing spring. The soft-closing spring maneuvers the door panel back to a pre-set closing position.
Implementation Method 2
the soft closing device is disposed to the door-closing direction to cushion the door panel. The soft closing device maneuvers the door panel to move towards the closing position.
Implementation Method 3
the soft closing device moderates a moving speed of the sliding door with a soft closing cylinder which is activated by the soft closing activation trigger

AI summary
A two-way soft closing device is mounted in a sliding door and has a sliding door track, two soft closing activation triggers, two roller carriers and a soft closing device. The sliding door track is an elongated member. The soft closing activation triggers are mounted movably in two ends of the sliding door track respectively. The roller carriers are mounted slidably in the sliding door track and are spaced apart at an interval. The soft closing device is mounted in the sliding door track, is located between the roller carriers and is mounted firmly in one of the roller carriers. Therefore, the soft closing device absorbs a collision between a sliding door plate and a doorframe when the sliding door is opened or is closed. Meanwhile, the two-way soft closing device eliminates noise coming from the collision and prevents an elder or a little child from being hit by the sliding door plate.
