Shelving Support Bracket Assembly to Reduce Impact Loading Stress
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 downtime, repair, or replacement.
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 couple 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 manufacturability and material costs are controlled, but strength and reliability deteriorate under loading conditions
Solution Approach 1:
The support bracket acts as an intermediary component between the lateral bracket and the support post. It distributes loads from the shelf through the support member to multiple retention members on the support post, reducing stress concentration on the lateral bracket and preventing premature failure under impact loading conditions
2Reliability
If support brackets are added to reduce stress on lateral brackets, then strength and reliability improve, but device complexity increases
Solution Approach 1:
The support bracket is segmented into distinct functional portions: an attachment portion for coupling to retention members and a support portion for coupling to the support member. This segmentation allows each portion to be optimized for its specific function while maintaining overall simplicity of the assembly
3Device complexity
If conventional bracket designs are used, then device complexity is minimized, but shelves experience premature failure due to bending, buckling, and fatigue
Solution Approach 1:
The support bracket provides beforehand cushioning by distributing impact loads across multiple retention members before they can concentrate on the lateral bracket. This prevents plastic deformation, dynamic fracture, and fatigue-induced fracture that occur in conventional designs under repeated impact loading

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.
