Divisible Multi-Axis Wheel Carrier for Tight-Space Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-axis carriages for suspended sliding doors face installation challenges when the horizontal distance between the rail and side wall is insufficient, making it difficult to insert the carriage into a C-profile runner.
Innovation Solution
A divisible carriage design composed of multiple base body parts that can be individually inserted into the rail and assembled, minimizing installation space requirements, with optional self-closing dampers for aligned and rigid connection, and an articulated self-closing damper to save space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the carriage is designed as a single assembled unit, then structural integrity is maintained, but the installation space required increases making it impossible to install in tight spaces
Solution Approach 1:
The carriage base body is divided into multiple separable parts (first base body part and second base body part) that can be inserted into the running rail individually and then connected together. This segmentation allows the carriage to be installed in tight spaces where a complete assembled carriage cannot fit, while maintaining structural integrity through the connection elements (protrusions and recesses) that join the parts together inside the rail.
2Area of stationary object
If the carriage is made divisible into multiple parts, then installation space is reduced, but the device complexity increases
Solution Approach 1:
The carriage base body is divided into multiple separable parts (first base body part and second base body part) that can be inserted into the running rail individually and then connected together. This segmentation allows the carriage to be installed in tight spaces where a complete assembled carriage cannot fit, while maintaining structural integrity through the connection elements (protrusions and recesses) that join the parts together inside the rail.
Solution Approach 2:
The multiple base body parts are designed with complementary connection elements (protrusions and recesses) that allow them to be easily joined together inside the running rail to form a complete carriage. This merging process restores the structural integrity of the carriage after individual insertion, combining the separate parts into a functional whole without requiring external assembly tools or complex procedures.
3Stability of the object's composition
If the self-closing damper is rigidly connected to the base body, then structural stability is improved, but the installation space required increases
Solution Approach 1:
The self-closing damper is connected to the base body part via an articulated (pivotable) connection instead of a rigid fixed connection. This dynamic connection allows the damper to pivot and adjust its position, enabling it to be installed in tighter spaces while still providing the necessary structural stability and self-closing function for the sliding door.
