Shelving Support Bracket Assembly for Impact Load Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shelving systems often face premature failure due to loading conditions, such as deformation, fracture, and fatigue, particularly in cantilevered shelves subjected to repeated impact loading, leading to undesirable downtime and costs.
Innovation Solution
A shelving system design featuring a support post with vertically spaced retention members and a support bracket with an attachment and support portion, where the support bracket includes a C-shaped region to securely engage with the shelf, reducing stress on lateral brackets and enhancing structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional shelving system designs are used, then manufacturing simplicity and material cost savings are achieved, but strength and reliability deteriorate under loading conditions
Solution Approach 1:
The bracket assembly is divided into distinct functional segments: a lateral bracket portion for mounting to the support post, and a support bracket portion for supporting the shelf. This segmentation allows each portion to be optimized for its specific function while maintaining overall structural integrity and strength.
Solution Approach 2:
The support bracket portion extends laterally from the lateral bracket portion, creating a three-dimensional configuration that distributes loads across multiple dimensions. This spatial arrangement enhances strength by creating a more robust load path from the shelf through the support bracket to the lateral bracket and finally to the support post.
2Reliability
If cantilevered shelves are used, then ease of installation and adaptability are improved, but reliability deteriorates under repeated impact loading
Solution Approach 1:
The lateral bracket portion and support bracket portion are merged into a single integrated bracket assembly that couples to the support post and supports the shelf simultaneously. This combination provides both the ease of installation of simple bracket systems and the enhanced reliability of multi-component structures through unified design.
3Strength
If individual shelves are used without support brackets, then device complexity is reduced, but strength deteriorates under bending and buckling loads
Solution Approach 1:
The support bracket portion is positioned locally at critical points where the shelf connects to the bracket assembly, providing targeted reinforcement against bending and buckling loads. This localized support enhances strength where needed most without requiring complex structures throughout the entire shelf system.

AI summary
A shelving system includes a support post having a mounting surface and a plurality of vertically spaced retention members extending from the mounting surface. A shelf includes a bracket member configured for coupling to a first of the vertically spaced retention members. A support bracket includes an attachment portion configured for coupling to a second of the vertically spaced retention members adjacent the first vertically spaced retention member and a support portion configured for coupling to the bracket member.
