Sliding Door Mounting Assembly with Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding door mounting arrangements are cumbersome to install, require skilled labor, and can be unreliable, often necessitating periodic adjustments and requiring multiple people for installation and maintenance.
Innovation Solution
A door mounting assembly comprising a carriage, a mounting plate, a securing plate, a pin, and a connection member with a threaded engagement, allowing for easy installation, height adjustment, and secure attachment of the door to the rail without requiring tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mounting arrangements are used, then the door can be mounted to the rail, but the installation process becomes cumbersome and requires two people to lift and locate the door
Solution Approach 1:
The mounting arrangement is divided into separate components: a mounting plate that attaches to the door, a carriage with wheels that moves along the rail, and a connection mechanism. This segmentation allows each component to be independently manufactured and assembled, simplifying the overall installation process while maintaining structural integrity.
Solution Approach 2:
The mounting plate serves as an intermediary component between the door and the carriage assembly. It provides a standardized interface that simplifies connection, allowing the door to be easily mounted to the carriage without requiring complex direct attachment mechanisms or multiple people for positioning.
2Reliability
If channels are routed in the top edge of the door to receive mounting hardware, then the mounting system can be secured, but skilled labor is required and it becomes unsuitable for DIY installation
Solution Approach 1:
The mounting plate is pre-attached to the door during manufacturing, with connection points and alignment features already prepared. This preliminary action eliminates the need for on-site channel routing or complex modifications, allowing DIY installation while maintaining reliable mounting through factory-prepared attachment mechanisms.
3Reliability
If latch mechanisms are included to attach the door to the carriage, then the door can be securely fastened, but the assembly becomes complex and latch can become jammed requiring destruction to remove the door
Solution Approach 1:
The complex latch mechanism is extracted and replaced with a simpler gravity-based retention system. The carriage assembly is designed to engage with the mounting plate through aligned slots and inherent friction, eliminating the need for separate latch components. This reduction in complexity prevents jamming while maintaining secure attachment through proper geometric engagement.
4Ease of manufacture
If plastic tabs or clips are used to secure components, then the components can be held in place, but they fail over time, dislodge, or become lost compromising the mounting system
Solution Approach 1:
The mounting plate and carriage components are constructed from metal materials with inherent structural integrity, replacing fragile plastic tabs and clips. The metal construction provides durable, permanent securing features that resist failure, dislodgement, and loss while maintaining ease of assembly through standardized connection interfaces.

AI summary
An assembly for mounting a door to a rail to move between open and closed positions, the assembly including a carriage, a mounting plate configured to be mounted to the top of the door, a pin extending between the carriage and the mounting plate, a connection member attached to or formed with the pin to connect the pin to the mounting plate, the connection member comprising a head and a neck, wherein the mounting plate has a slot, the slot including a lower portion and an upper portion, the upper portion dimensioned to receive the neck and the lower portion dimensioned to receive the head, and wherein the head is too wide to be received in or pass through the upper portion so that in use the door hangs from the mounting assembly with the mounting plate bearing on the head of the connection member.
