Bent U-Profile Cantilever Bracket for Stepless Rail Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cantilever systems face challenges with non-adjustable brackets requiring different screw lengths and limited installation positions due to standard locations, leading to manufacturing complexity and instability of shelves.
Innovation Solution
A cantilever system featuring a profile rail with an elongated opening and opposing counter-surfaces, where a bracket manufactured from a single plate piece by bending forms a U-profile cross-section, providing pulling and pushing surfaces for secure installation and adjustment, with a locking mechanism to prevent lateral buckling and ensure stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If brackets are designed with U-shaped cross-section narrowing outwards, then the bracket structure is simple, but different screw lengths are required for attachment
Solution Approach 1:
The bracket features a U-shaped cross-section that narrows inwards rather than outwards, creating a local geometric variation at the attachment region. This design allows all attachment screws to be of uniform length while maintaining structural simplicity, as the narrowing occurs locally at the flange region where attachment is needed.
2Ease of manufacture
If standard locations are provided in the rail for brackets, then manufacturing is simplified, but installation positions are limited to discrete points
Solution Approach 1:
The bracket incorporates a stepless adjustment mechanism along the rail, transforming the static, discrete installation positions into a dynamic, continuous adjustment system. The bracket can be positioned at any location along the rail's length, providing versatility while maintaining manufacturing simplicity through standardized bracket designs.
3Adaptability or versatility
If brackets are made steplessly adjustable in rails, then installation flexibility is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The bracket is divided into distinct functional segments: a U-shaped flange portion for attachment, a web portion for structural support, and an adjustment mechanism portion for stepless positioning. This segmentation allows each component to be optimized independently, achieving installation flexibility without excessive overall complexity.
4Adaptability or versatility
If shelves are attached to adjustable brackets, then positioning flexibility is improved, but attachment difficulty increases
Solution Approach 1:
The bracket includes pre-formed attachment flanges with standardized hole patterns and a U-shaped cross-section that narrows inwards, creating a self-guiding attachment structure. This preliminary design of the attachment interface simplifies shelf installation, as the flange geometry automatically aligns and guides the attachment screws during installation.

AI summary
A cantilever system includes at least one profile rail and at least one bracket for installation in the profile rail. The profile rail includes an elongated opening for the bracket and opposing counter-surfaces inside the profile rail for pulling and pushing caused by the bracket when installed on the profile rail. The bracket includes a widening to be fitted inside the profile rail arranged to form a pulling surface for creating the pulling when the bracket is installed in the opening in the profile rail, and a pushing surface for creating the pushing when the bracket is installed in the opening in the profile rail. The cross-section of the bracket is arranged, in the part that is outside the profile rail, to be at least locally a sideways opening U-profile, when the bracket is installed in the profile rail. The bracket is manufactured from a single plate piece by bending.
