Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current suspended sliding door mounting systems face issues such as uncontrolled door momentum, sway in transverse planes, and bulky, aesthetically unpleasing hardware, which can lead to damage and limited application in various environments.
Innovation Solution
A door mounting system featuring a horizontally elongated support rail, wall mounts, a door bracket with a hook-shaped hanger and anti-sway clip, and a linear needle roller bearing for smooth operation and stability, constructed from materials like stainless steel for durability and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If large diameter pulley wheels are used to support the door weight, then the door can be suspended and slide smoothly, but the door gains significant momentum and may strike the track ends with considerable force causing damage
Solution Approach 1:
The patent changes the wheel diameter parameter from large to small (less than 1 inch), fundamentally altering the momentum characteristics while maintaining load-bearing capacity through multiple wheels and proper mounting geometry
2Ease of operation
If a fixed rail track system is used to guide the door, then the door can slide in a controlled manner, but the system lacks means to resist door movement and swaying in the transverse direction when pushed or leaned against
Solution Approach 1:
The patent segments the door support function into multiple independent small wheels distributed across the door width, each providing both sliding guidance and transverse stability, rather than relying on a single large pulley system
Solution Approach 2:
The patent merges the functions of door suspension, sliding guidance, and transverse stability resistance into a single integrated small wheel assembly that performs all three functions simultaneously
3Ease of operation
If traditional mounting hardware is used for suspended sliding doors, then the door can be mounted and operated, but the hardware is bulky and unrefined in ornamental appearance, limiting aesthetic applications
Solution Approach 1:
The patent dramatically reduces the wheel diameter parameter to less than 1 inch, transforming the hardware from bulky and conspicuous to compact and aesthetically pleasing, suitable for visible interior applications
Solution Approach 2:
The patent employs thin profile wheels with minimal visual bulk, creating a sleek, refined appearance that blends well with interior aesthetics while maintaining full functional capability
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 system reduces door momentum, prevents swaying, and enhances aesthetics, making it suitable for various applications including bathrooms, while ensuring smooth operation and structural strength.
Implementation Method 1
a linear needle roller bearing disposed at an interface between the door bracket and the support rail to facilitate sliding movement of the door bracket along the support rail

AI summary
A door mounting system for sliding translation of a door in one embodiment may include a longitudinally elongated support rail defining a mounting axis, a pair of wall mounts rigidly anchoring the support rail to a support surface, a door bracket slideably movable along the support rail, a door supported by the door bracket in a suspended manner, and a linear roller bearing disposed at an interface between the door bracket and support rail to facilitate movement of the door bracket along the support rail. The door is linearly translatable along the support rail in operation between open and closed positions. In one embodiment, an anti-sway clip disposed on the door bracket defines a stop surface configured to engage the support rail to arrest swaying motion of the door if a force is inadvertently applied to the door acting in a plane oriented transversely to the mounting axis.
