Slide Device with Intermediary Sub-Transfer Pin to Reduce Slider Wear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional slide devices for furniture and drawers have complex structures and reduced durability due to direct coupling of the damper's rod end portion to the slider, leading to degradation during long-term reciprocating movement.
Innovation Solution
A slide device with a sub-transfer pin interposed between the transfer pin and the damper, allowing the rod end portion of the damper to be detachably coupled to the sub-transfer pin, which is rotatable about the transfer pin, thereby simplifying the coupling structure and reducing direct impact on the slider.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the rod end portion of the damper is directly coupled to the slider, then the coupling structure is simple, but the durability of the slider is reduced during long-term reciprocating movement
Solution Approach 1:
The sub-transfer pin serves as an intermediary component between the damper's rod end portion and the transfer pin. The rod end portion is detachably coupled to the sub-transfer pin, which is rotatable about the transfer pin, thereby preventing direct coupling between the damper and slider. This intermediary structure reduces the transmission of damper operation impacts to the slider, enhancing slider durability while maintaining coupling simplicity.
2Adaptability or versatility
If the slider is coupled with both the rod end portion of the damper and the transfer pin, then the coupling function is complete, but the structure of the slider becomes complicated
Solution Approach 1:
The coupling function is segmented into multiple components: the rod end portion couples to the sub-transfer pin, which in turn couples to the transfer pin, which couples to the slider. This segmentation distributes the coupling functions across different components rather than concentrating them all in the slider, thereby maintaining complete coupling functionality while simplifying the slider structure.
3Quantity of substance
If the rod end portion of the damper is directly connected to the slider, then the number of parts is reduced, but the impact transmission to the slider increases
Solution Approach 1:
The sub-transfer pin acts as a mediator that absorbs and dissipates impact forces from the damper's rod end portion before they reach the transfer pin and slider. Although this adds one additional part, it significantly reduces the force transmission to the slider, protecting it from impact damage during damper operation.

AI summary
Disclosed is a slide device including: a body provided at an end portion of a side of the fixed rail, and provided with a guide path; a slider coupled to the body, and selectively slidably movable along a longitudinal direction of the body during slidable movement of the transfer rail; a transfer pin coupled to the slider to be movable simultaneously at the time of movement of the slider, and movable along the guide path; and a damper provided in the body, and configured such that a rod end portion thereof is connected to the transfer pin. The present invention employs a structure in which the rod end part of the damper is detachably coupled to a sub-transfer pin without being directly coupled to the slider, and thereby can maximally prevent occurrence of a problem where the durability of the slider degrades during long-term reciprocating movement.
