Sliding Door Floor Roller Adjustment for Vertical Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding door systems tilt due to uneven floors or misalignment, leading to aesthetic issues and functional limitations, particularly with glass and aluminum-framed doors, and are not suitable for double sliding doors.
Innovation Solution
An adjustable device with articulated plastic or metal components and elastic sheets compensates for tilting by aligning sliding doors vertically, using screws to adjust the tilting support and accommodate floor depressions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If spring-loaded wheels are used for floor movement, then the door can slide smoothly, but the door tilts due to uneven flexion of the wheels
Solution Approach 1:
The device incorporates an adjustable mechanism that allows the support structure to be dynamically repositioned vertically. The adjustment means enable the user to modify the height of the spring-loaded wheel support relative to the door, compensating for tilting caused by uneven wheel flexion during sliding operation.
2Adaptability or versatility
If the door slides on an uneven floor, then the door can adapt to floor variations, but the door tilts and becomes misaligned vertically
Solution Approach 1:
The device changes the vertical position parameter of the spring-loaded wheel support through the adjustment mechanism. This parameter modification allows the system to compensate for floor unevenness and maintain proper vertical alignment of the door despite variations in the floor surface.
3Shape
If the door is made of glass with aluminum frame, then aesthetic appeal is improved, but the tilt becomes more visible and unacceptable
Solution Approach 1:
The adjustable support mechanism provides dynamic vertical positioning capability that allows precise alignment of glass and aluminum-framed doors. By enabling fine-tuning of the wheel support height, the device ensures that the aesthetic appearance of these visually prominent door types is maintained without visible tilting.
4Ease of manufacture
If a fixed support structure is used, then manufacturing is simpler, but the device cannot compensate for tilting or floor depressions
Solution Approach 1:
The device transitions from a fixed support structure to a dynamically adjustable one. The adjustment mechanism, while adding some complexity, enables the support structure to adapt to various conditions including tilting and floor depressions, providing versatility without significantly complicating the overall design.
Solution Approach 2:
The support structure is segmented into adjustable components that can be independently positioned. This segmentation allows the adjustment mechanism to be integrated in a modular fashion, maintaining manufacturing simplicity while enabling tilt compensation functionality.

AI summary
An adjustable device (10) for the movement on the floor of single or double sliding door(s) (12) to be aligned with a wall (14) comprises a rubber wheel (16) connected through a pin (20) to a frame (18), combined with a pad (26) made of elastomeric material and provided with overlapping elastic sheets (22), fixed with screws (24) to a load-bearing frame. Said frame is formed by a fixing base (28) and by a tilting support (36) in which the means for adjustment and alignment of the door(s) (12) are arranged. The fixing base (28) defines a substantially rectangular plane and is provided, along the opposite major sides, with integral flanks (30) folded at 90° on each of which, at one end of the same fixing base (28), a through hole (32) is formed to accommodate a pin (34) for connecting and articulating to the tilting support (36).
