Sliding Door Elastic Tension Mechanism for Reliable Closure
Solution Overview
Problem
Existing sliding door systems often fail to ensure complete closure, leading to reduced insulation against sound and heat loss, especially in frequently used areas, and motorized drives are costly and space-intensive.
Innovation Solution
A sliding door system equipped with a locking device featuring an elastic traction mechanism, where one end is fixed to the roller track and the other end is attached to the roller carriage, allowing for automatic closure through stored tensile stress, enabling complete and secure closure without the need for additional motorized components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a motorized drive is used to ensure complete closure of the sliding door, then the closure reliability is improved, but the device complexity and cost increase
Solution Approach 1:
The elastic traction means automatically pulls the roller carriage to the closed position without requiring external power sources or control systems. The system uses the stored elastic energy to self-close the door, eliminating the need for motorized drives while maintaining closure reliability.
Solution Approach 2:
The elastic traction means is pre-tensioned during installation to store the necessary closing force. This preliminary action of tensioning the elastic element ensures that the closing force is available whenever needed, without requiring active control or power during operation.
2Extent of automation
If a motorized drive is installed to achieve automatic closure, then the automation level is improved, but the weight and space requirements increase
Solution Approach 1:
The elastic traction means provides automatic closure functionality without requiring heavy motorized components. The lightweight elastic element replaces the need for motors, power supplies, and control electronics, dramatically reducing the weight added to the sliding door system.
3Device complexity
If manual operation is used to close the sliding door, then the device complexity is reduced, but the closure reliability deteriorates
Solution Approach 1:
The elastic traction means automatically ensures complete closure without requiring user intervention, eliminating the reliability issue of manual operation while keeping the system simple. The elastic element acts as a passive enforcement mechanism that guarantees closure.
Solution Approach 2:
The pre-tensioned elastic traction means creates a closing force that counteracts any tendency for the door to remain open. This preliminary application of closing force ensures that the door is reliably pulled shut, preventing the incomplete closure problem associated with manual operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides a cost-effective and simple solution for ensuring complete closure, enhancing sound and heat insulation by utilizing the elastic traction mechanism to automatically close the door, reducing the need for high-cost motor drives and complex installations.
Implementation Method 1
A locking device (40) is provided with an elastic traction means (42). The elastic deformation leads to an increase in the tensile stress within the elastic traction means when the roller carriage moves into the open position.
Implementation Method 2
Due to the stretching of the elastic traction means, this necessary force is accordingly stored in the form of tensile stress in the elastic traction means.
