Slide Rail Buffer Seat Design to Avoid Roller Path Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail structures with balls are insufficient for heavy loads, leading to potential derailment or wear issues, and cannot accommodate damping buffers due to path interference with rollers.
Innovation Solution
A slide rail structure with a buffer seat that allows for easy assembly of a damping buffer, featuring a first rail with a buffer seat having engaging units for mounting in different directions, enabling high stability and load-bearing capabilities without complex steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If balls are used in the slide rail structure, then friction and noise are reduced, but the load-bearing capacity is insufficient for heavy objects
Solution Approach 1:
The patent changes the operational parameter from balls to rollers, which have different mechanical properties. Rollers provide both reduced friction through rolling motion and increased load-bearing capacity due to their larger size and structural characteristics, resolving the contradiction between friction reduction and load-bearing capacity for heavy objects
2Strength
If rollers are used instead of balls for heavy loads, then load-bearing capacity is improved, but the damping buffer cannot be mounted due to path interference
Solution Approach 1:
The patent introduces a buffer seat that extends in a direction perpendicular to the sliding direction of the rollers. This dimensional change allows the damping buffer to be mounted on the buffer seat without interfering with the operational path of the rollers, thus maintaining both load-bearing capacity and adaptability for damping buffer mounting
3Adaptability or versatility
If a buffer seat is added to accommodate the damping buffer, then adaptability is improved, but the structure becomes more complex
Solution Approach 1:
The buffer seat is designed to serve multiple functions: it provides a mounting platform for the damping buffer, maintains the structural integrity of the slide rail assembly, and does not interfere with roller operation. This multi-functionality increases adaptability while minimizing the increase in structural complexity

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 slide rail structure provides high stability and load-bearing capabilities, allowing for the assembly of a damping buffer on heavy-loaded drawers without interfering with roller paths, reducing friction and noise, and enhancing flexibility and adaptability.
Implementation Method 1
the second rail has a roller set, the roller set has a plurality of rollers, and the rollers enable the second rail to slide relative to the first rail
Implementation Method 2
the side roller assembly has a side roller and a position-limiting unit, the side roller is rotatably mounted on the position-limiting unit, and the side roller abuts against the first slot wall
Implementation Method 3
a buffer seat mounted on the first side wall, the buffer seat having two engaging units, the two engaging units being disposed oppositely

AI summary
A slide rail structure with a buffer seat, which comprises: a first rail having a first slot wall and a first side wall connected to the first slot wall, the first slot wall and the first side wall extend in different directions; a movable rail having a roller set and a side roller assembly mounted on the first rail and capable of slidably moving relative to the first rail; and a buffer seat mounted on the first side wall, the buffer seat has two engaging units, the two engaging units are disposed oppositely, and the engaging unit has an engaging hole and at least one second lock hole, thereby the buffer seat is fixed to the first rail to avoid a travel path of the roller set of the movable rail overlapping with a position of a buffer.
