Sliding Door Ejection Linkage for Single-Plane Closet Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sliding doors in closets often require multiple tracks and complex mechanisms to operate in parallel planes, leading to installation challenges and interference when opening or closing, necessitating one door to move outwardly to allow others to slide properly.
Innovation Solution
A system comprising multiple ejection assemblies and a connecting mechanism that allows simultaneous movement of sliding doors by applying forces at different locations, using rails, rods, or hydraulic/pneumatic systems to synchronize the movement of all doors, enabling them to operate in the same plane without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple tracks are used for sliding doors, then door obstruction is avoided, but device complexity increases
Solution Approach 1:
The patent merges multiple track systems into a single shared track by implementing a parallel mounting mechanism that allows adjacent sliding doors to operate on the same track simultaneously, eliminating the need for separate tracks for each door while maintaining reliable operation
Solution Approach 2:
The patent introduces a new dimensional approach by allowing doors to mount parallel to the track rather than perpendicular, enabling multiple doors to share the same track space through optimized spatial arrangement and mounting geometry
2Reliability
If doors are installed at different planes, then obstruction is avoided, but ease of operation deteriorates
Solution Approach 1:
The patent introduces a connecting mechanism that acts as an intermediary between multiple sliding doors, mechanically linking them to ensure synchronized movement and simultaneous opening/closing operations while maintaining reliable sliding performance
3Reliability
If multiple tracks are used, then door obstruction is prevented, but space efficiency decreases
Solution Approach 1:
The patent combines multiple track functions into a single shared track structure, allowing adjacent doors to operate on the same track, thereby reducing the total track length required and optimizing closet space utilization while maintaining reliable door operation

AI summary
A system of ejecting a sliding door of a closet, comprising a plurality of ejection assemblies and a connecting mechanism, which connects one assembly to the other. Each ejection assembly comprises a rail and a slidable member configured to slide along the rail, where the rail engages with a frame of the closet. The connecting mechanism allows synchronizing the ejection force applied upon the door at different locations of the door, by connecting the ejection assemblies through the connecting mechanism. This configuration allows ejecting and retrieving of the door outwardly and inwardly by sliding the slidable member of each assembly along the rail.
