Adjustable Fixing Bracket for Open Rack Slide Rails
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional open rack designs for industrial computer chassis suffer from unstable chassis movement and increased manufacturing costs due to limited fixation options and equidistantly arranged ladder pieces, which restrict the installation of multiple chassis in limited spaces and rely excessively on slide rails for support.
Innovation Solution
A fixing bracket structure for slide rails with adjustable width, comprising a fixed cover, sliding cover, and reinforcing cover, allowing for flexible positioning and reinforcement, utilizing C-shaped structures and metal stamping for cost-effectiveness, to improve installation convenience and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional open rack design with equidistant ladder pieces is used, then manufacturing is simplified, but the slide rail structure cannot be attached closely and gaps exist
Solution Approach 1:
The fixing bracket incorporates a sliding cover that can move along the fixed rail to adjust its position dynamically. This allows the bracket to adapt to different chassis widths and positions, eliminating gaps between the slide rail structure and the chassis while maintaining manufacturing simplicity through the standardized C-shaped design.
2Device complexity
If one-sided fixation is used, then device complexity is reduced, but chassis movement stability deteriorates
Solution Approach 1:
The fixing bracket is divided into distinct functional segments: a fixed cover attached to the fixed rail, a sliding cover that moves along the rail, and a reinforcing cover that provides additional support. This segmentation allows each part to perform its specific function while collectively providing stable two-sided fixation without excessive complexity.
Solution Approach 2:
The fixing bracket transitions from one-sided to two-sided fixation by utilizing both the fixed cover and sliding cover on opposite sides of the chassis. This dimensional expansion from single-point to multi-point fixation significantly improves chassis movement stability while maintaining reasonable device complexity through the modular design.
3Strength
If slide rail is fixed by multiple fasteners, then fixation strength is improved, but manufacturing cost increases
Solution Approach 1:
The fixing bracket merges the functions of multiple fasteners into an integrated C-shaped structure that combines the fixed cover, sliding cover, and reinforcing cover into a single unified component. This merging reduces the number of separate parts and fastening operations required, thereby reducing manufacturing cost while maintaining or improving fixation strength through the distributed load path of the multi-layer cover structure.
4Device complexity
If fixed size chassis are designed, then device complexity is reduced, but adaptability to different chassis sizes deteriorates
Solution Approach 1:
The sliding cover can move along the fixed rail to adjust its position, enabling the fixing bracket to adapt to different chassis widths and positions. This dynamic adjustment capability provides versatility across different chassis sizes while maintaining the simplicity of the C-shaped design and equidistant ladder piece arrangement.

AI summary
A fixing bracket for a slide rail of an open rack includes a fixed cover, a sliding cover and plural fasteners. Both fixed and sliding covers cover the exterior of the slide rail, and the sliding cover can slide appropriately with limitation, and a pair of the slide rails are installed symmetrically on both sides of a chassis, and the fixing bracket is provided for fixing the chassis onto an open rack which is a rectangular enclosed frame structure similar to a door frame, and the fixed cover and the sliding cover have a first fixing plate and a second fixing plate configured to be corresponsive to the open rack. With a sliding design of the sliding cover, the fasteners can be used to fix the chassis onto the two opposite sides of the rack by adjusting the width of the open rack.
