Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies lack sufficient structural strength and stability to meet diverse market requirements, particularly when carrying objects under gravity.
Innovation Solution
A slide rail assembly comprising a first rail, a slide assisting device, and a second rail, where the first rail features a passage with a rolling member and predetermined parts with ball grooves, enhancing structural strength through bent middle walls and shoulder sections that improve the stability of the rolling members between grooves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional slide rail assembly is used, then the device complexity is low, but the structural strength and stability are insufficient to meet diverse market requirements
Solution Approach 1:
The slide rail assembly is divided into multiple functional segments: a first rail with a passage, a second rail with rolling members, and reinforcement structures including bent middle walls and shoulder sections. This segmentation allows each component to perform its specific function while collectively achieving enhanced structural strength without excessive overall complexity.
Solution Approach 2:
The middle wall of the first rail is bent to form a three-dimensional reinforcement structure that extends beyond the flat plane. This dimensional change creates additional structural support in the vertical and lateral directions, significantly improving the overall strength and stability of the slide rail assembly.
2Reliability
If rolling members are added to enhance stability, then the structural strength improves, but the device complexity increases
Solution Approach 1:
The rolling members are positioned within the passage formed by the first and second rails, where they automatically self-align and self-support as the second rail moves relative to the first rail. The bent middle wall and shoulder sections provide inherent guidance and containment, eliminating the need for additional complex retention mechanisms.
3Strength
If reinforcement structures are added to prevent detachment, then the strength improves, but the ease of manufacture decreases
Solution Approach 1:
The reinforcement functions are merged into the existing rail structures. The middle wall of the first rail is bent to simultaneously provide structural reinforcement and define the passage geometry. The shoulder sections are integrated into the rail bodies, combining support functions with the primary structural components, thereby reducing the need for separate attachment parts.
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 significantly enhances the structural strength and stability of the slide rail assembly, preventing detachment of the second rail and ensuring effective support for carried objects by utilizing rolling members within ball grooves and reinforcing features.
Implementation Method 1
The slide assisting device comprises a first rolling member. The first rolling member is located between the first ball groove and the second ball groove.
