Folding-Sliding Door Guide System Decoupling Carrier and Receptacle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide systems for folding-sliding doors experience uneven wear and premature failure due to one-sided loads and kinematic issues caused by the weight and adjustment of door leaves, leading to twisting and tilting of the carrier, which affects the support rollers and guide rails.
Innovation Solution
The guide system decouples the receiving device from the carrier by allowing them to move relative to each other in the longitudinal direction, with separate rollers on each component, supported on distinct catwalks of the guide rail, ensuring that the receiving device remains unaffected by loads and movements of the carrier, and includes a mechanical spring or damping element for further stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the receiving device is rigidly connected to the carrier, then the structure is simpler, but the support roller experiences one-sided loading and uneven wear due to carrier twisting and tilting
Solution Approach 1:
The receiving device is separated from the carrier and allowed to move independently along the guide rail. This segmentation decouples the receiving device from the carrier's twisting and tilting movements, preventing one-sided loading on the support roller while maintaining structural simplicity through modular design.
Solution Approach 2:
The receiving device is designed to be movable relative to the carrier along the guide rail, transforming a rigid static connection into a dynamic adjustable connection. This allows the receiving device to compensate for carrier position changes and maintain proper alignment, reducing wear on the support roller.
2Stability of the object's composition
If the carrier and receiving device are rigidly connected, then the alignment is more stable, but the support roller becomes tilted relative to the guide rail due to carrier twisting
Solution Approach 1:
By separating the receiving device from the carrier and allowing independent movement, the system maintains alignment stability through the guide rail's constraints while preventing the transmission of twisting forces that would tilt the support roller.
Solution Approach 2:
The guide rail acts as an intermediary between the carrier and receiving device, providing a stable reference that maintains alignment while allowing the receiving device to move independently and compensate for carrier position changes.
3Duration of action of stationary object
If the receiving device is decoupled from the carrier with separate rollers on distinct catwalks, then wear is reduced and lifespan is extended, but the device complexity increases
Solution Approach 1:
The guide system is segmented into distinct functional components (carrier, receiving device, support roller, guide device) with separate rollers on distinct catwalks. This segmentation reduces wear by preventing load transmission between components while maintaining reasonable complexity through modular design.
Solution Approach 2:
The guide rail serves multiple functions: guiding the carrier's movement, supporting the receiving device's independent motion, and providing alignment reference. This multi-functionality reduces the need for additional components, balancing lifespan extension with controlled complexity.
