Slide Rail Assembly with Position-Based Damping Detachment Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies lack the ability to provide customizable damping effects based on the distance of movement between slide rails, limiting their adaptability to various market requirements.
Innovation Solution
A slide rail assembly with a damping device and an auxiliary member that switches states to provide damping effect only when a predetermined distance is reached, using an elastic component to detach from the damping device upon further movement, allowing for direct and obvious damping control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the damping device is continuously engaged during the entire movement of the second rail relative to the first rail, then the damping effect is maintained throughout the movement, but the damping effect cannot be customized based on predetermined movement distances
Solution Approach 1:
The auxiliary member is designed to dynamically switch between engaged and disengaged states with the damping device based on the movement distance of the second rail. This dynamic state change allows the damping effect to be activated only during specific movement phases, providing customizable damping control without requiring a completely complex control system.
Solution Approach 2:
The auxiliary member automatically engages or disengages from the damping device based on the predetermined movement distance of the second rail relative to the first rail, without requiring external control. The system uses the movement itself to trigger the state change, making the damping control self-regulating and reducing overall system complexity.
2Ease of operation
If the auxiliary member remains in constant contact with the damping device, then continuous damping is provided, but the damping effect cannot be detached at predetermined positions
Solution Approach 1:
The movement range of the second rail is divided into different zones: a first movement range where the auxiliary member is engaged with the damping device to provide damping effect, and a second movement range where the auxiliary member is disengaged to allow free movement. This segmentation of movement ranges enables precise control over when damping is applied.
Solution Approach 2:
The auxiliary member transitions from a static constant-contact state to a dynamic state that automatically engages and disengages based on the movement distance. This dynamic behavior allows the damping effect to be selectively applied only when needed, improving ease of operation while maintaining relatively simple mechanics.
3Loss of energy
If the damping device provides damping effect throughout the entire movement range, then impact is reduced continuously, but energy is wasted when damping is not needed
Solution Approach 1:
The damping effect is applied periodically rather than continuously - it is activated only during the first movement range when the auxiliary member is engaged with the damping device, and deactivated during the second movement range when the auxiliary member is disengaged. This periodic application of damping reduces energy consumption while still providing impact reduction when needed.
Solution Approach 2:
The system discards the damping effect (by disengaging the auxiliary member) when it is not needed during the second movement range, and recovers it (by re-engaging the auxiliary member) when needed during the first movement range. This selective engagement and disengagement optimizes energy usage while maintaining impact protection when required.
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 assembly provides direct and customizable damping effects, reducing impact and ensuring smooth operation by detaching damping when the predetermined position is approached, enhancing user experience and functionality.
Implementation Method 1
the auxiliary member is an elastic component. During a process of the second rail being moved relative to the first rail along an opening direction, the auxiliary member is configured to abut against the damping device to drive the damping device to provide damping effect; and when the second rail is further moved relative to the first rail along the opening direction, the predetermined feature is configured to abut against the auxiliary member to elastically deform the auxiliary member to be detached from the damping device

AI summary
A slide rail assembly includes a first rail, a second rail, a damping device and an auxiliary member. The first rail is arranged with a predetermined feature. The second rail is movable relative to the first rail. The damping device is arranged on the first rail. The auxiliary member is arranged on the second rail. During a process of the second rail being moved relative to the first rail along a direction, the auxiliary member is configured to abut against the damping device such that the damping device provides damping effect. When the second rail is further moved relative to the first rail along the direction, the predetermined feature is configured to abut against the auxiliary member to drive the auxiliary member to be detached from the damping device.
