Adjustable Door Carriage for Wall Irregularities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding systems for doors face challenges during installation due to the need for precise alignment of carriages on non-planar walls and the inability to adjust for inclined or incorrectly positioned carriages, leading to improper sliding and potential misalignment of wheels with the section.
Innovation Solution
An adjustable carriage system that allows for the adjustment of the second section relative to the first section in both vertical and horizontal planes, using a central pin for oscillation and adjusting screws for precise alignment, ensuring proper contact and alignment of wheels with the section, and includes locking and anti-screwing mechanisms for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the carriage is fixed to the wall using traditional fixing methods, then the installation process is simple, but the wheels may not be properly aligned with the section due to operator errors or wall irregularities
Solution Approach 1:
The carriage incorporates adjustable elements that allow dynamic modification of its position and orientation relative to the wall. The carriage can be adjusted in terms of its longitudinal axis orientation and vertical position to compensate for installation errors or wall irregularities, ensuring proper alignment of wheels with the section while maintaining ease of installation.
Solution Approach 2:
The invention enables change in critical parameters of the carriage installation, specifically the orientation angle of the longitudinal axis and the vertical height position. These parameters can be adjusted within certain ranges to optimize the alignment between carriage wheels and the section, resolving the contradiction between simple installation and precise alignment.
2Adaptability or versatility
If the carriage is installed on a non-planar or inclined wall, then the system can adapt to various wall conditions, but the wheels will not be in proper contact with the section causing incorrect sliding
Solution Approach 1:
The carriage includes adjustable mechanisms that allow dynamic adaptation to non-planar and inclined wall surfaces. The longitudinal axis orientation and vertical position can be modified to compensate for wall irregularities, ensuring that the wheels maintain proper contact with the section and achieve reliable sliding performance across various wall conditions.
Solution Approach 2:
The carriage design provides universal adaptability to different wall conditions including planar, non-planar, inclined, and recessed surfaces. The adjustable orientation and position features enable the same carriage to reliably perform on diverse wall geometries, ensuring consistent sliding reliability without requiring different carriage types for different wall conditions.
3Ease of repair
If adjusting means are provided to correct carriage position, then installation errors can be remedied, but the system cannot adjust the orientation of the first section relative to the second section
Solution Approach 1:
The carriage incorporates dual adjustment capabilities: vertical position adjustment to correct height errors and longitudinal axis orientation adjustment to correct angular misalignment. These dynamic adjustment features enable the system to remedy both positional and orientational installation errors, providing comprehensive error correction and enhanced adaptability.
Solution Approach 2:
The invention adds orientation adjustment capability to the existing vertical position adjustment. By enabling adjustment in both vertical position and longitudinal axis orientation dimensions, the system gains comprehensive error correction capability, allowing it to remedy not only height errors but also angular misalignment errors during installation.
4Manufacturing precision
If spacers are used to align the carriage with the section, then the wheels can be properly positioned, but the carriage is not firmly fixed to the wall and the alignment is difficult to implement accurately
Solution Approach 1:
The carriage integrates adjustable orientation and position features directly into the fixing mechanism itself, eliminating the need for separate spacer components. This integrated approach achieves precise alignment through controlled adjustment of the carriage's longitudinal axis and vertical position, while maintaining firm fixation to the wall without requiring additional alignment components.
