Synchronic drawer slide rail system with mute springback function
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drawer slide rail systems with automatic springback mechanisms face issues of large space occupation and reduced carrying capacity due to the placement of damping devices inside the slide rail, which limits the length of the middle rail and overall carrying capacity, especially when large drawers are involved.
Innovation Solution
A synchronic drawer slide rail system with a mute springback function is designed, where the slide rail springback mechanism is installed in a shell unit below the internal face of the slide rail, eliminating the need for internal space and allowing the middle and outer rails to maintain equal length, ensuring adequate carrying capacity and a sleek appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the damping device is installed inside the slide rail at the rear end of the outer rail, then the automatic springback mechanism can ensure stable buffering effect and reduce noise, but the installation space inside the slide rail increases, resulting in a large space occupation rate and reduced carrying capacity
Solution Approach 1:
The damping device is relocated from the horizontal dimension (inside the slide rail) to the vertical dimension (below the cabinet), utilizing unused space in a different spatial direction. This allows the slide rail to maintain its structural integrity and carrying capacity while the damping function is preserved through the vertically positioned damping device connected via a connecting rod.
2Extent of automation
If the damping device is installed inside the slide rail, then the automatic closing function can be achieved, but the length of the middle rail must be shortened, reducing the overlap length with the outer rail and the overall carrying capacity
Solution Approach 1:
The automatic closing mechanism is reconfigured by positioning the damping device in the vertical dimension below the cabinet, allowing the middle rail to extend its full length horizontally without accommodation for the damping device. The connecting rod transmits the damping force from the vertical position to the horizontal slide rail mechanism, preserving both the automatic closing function and the rail length.
3Ease of operation
If the damping device is placed at the bottom end inside the slide rail, then the springback mechanism can operate, but the appearance becomes bulky and the aesthetic appeal is reduced
Solution Approach 1:
The damping device is extracted from the visible interior space of the slide rail assembly and repositioned to the external area below the cabinet. This separation removes the bulky damping device from the aesthetic field of view while maintaining its operational connection to the slide rail through the connecting rod, thus preserving both functionality and appearance.
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
This design effectively reduces the space occupancy rate of the slide rail system, maintains the length of the middle rail for enhanced carrying capacity, and protects the springback mechanism from external pollution, ensuring reliable operation and aesthetic appeal.
Implementation Method 1
the first one is driven only by a springback force of the spring to automatically close the drawer slide rail
Implementation Method 2
the second one automatically closes the drawer with cooperation of the spring and the damping device, wherein the damping device can ensure that the drawer slide rail slowly and automatically closes under the springback action, keeping the stable buffering effect in the process of automatic closing, and greatly reducing the noise
