Solution Overview
Problem
Conventional dampers require air cylinders with the same length as springs, leading to excessive space occupation and increased size of sliding rails due to the need for matching cylinder lengths.
Innovation Solution
A damper assembly with a telescopic cylinder that is compressed through a limiting piece and sliding block mechanism, allowing for a reduced compression stroke relative to the sliding stroke, thereby minimizing the size of the air cylinder and damping structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air cylinder length is matched with the spring length in conventional dampers, then the damping function is achieved, but the air cylinder becomes excessively long and occupies large space
Solution Approach 1:
The patent changes the compression direction of the air cylinder from parallel to the sliding rail (one-dimensional) to perpendicular to the sliding rail (another dimension). The air cylinder is mounted perpendicular to the sliding direction, compressing along a different spatial axis, which allows the damping function to be achieved without increasing the length along the sliding rail direction.
Solution Approach 2:
The patent introduces a dynamic linkage mechanism consisting of a sliding block and a connecting rod that converts the linear sliding motion into perpendicular compression motion of the air cylinder. The connecting rod rotates and translates, dynamically transferring the sliding block's displacement into air cylinder compression, enabling compact spatial arrangement.
2Volume of stationary object
If the air cylinder is made shorter to reduce space occupation, then the space requirement is reduced, but the damping performance may be compromised
Solution Approach 1:
The dynamic linkage mechanism amplifies the effect of the air cylinder's short compression stroke. As the sliding block moves along the rail, the connecting rod's rotational motion converts this into effective compression of the short air cylinder, maintaining damping performance despite the reduced cylinder length.
Solution Approach 2:
The connecting rod acts as an intermediary mechanism between the sliding block and the air cylinder. It transfers and transforms the motion and force, allowing the short air cylinder to exert its damping effect effectively on the sliding block's motion along the rail.
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 solution reduces the space occupied by the damping piece, lowers the cost, and maintains effective damping performance by converting telescopic cylinder force into resistance, without the need for a long air cylinder.
Implementation Method 1
the telescopic cylinder and the limiting piece have a first relative position and a second relative position; in the process that the tension piece pulls the sliding block to move from the first position to the second position, the telescopic cylinder moves from the first relative position to the second relative position; and in the process that the telescopic cylinder moves from the first relative position to the second relative position, the telescopic cylinder is gradually compressed
