Backstop support bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backstops for pallet racks are prone to bending or wear, leading to ineffective positioning of containers or pallets, which can violate fire and safety regulations by obstructing air circulation and fire extinguishing access.
Innovation Solution
A backstop bracket with a horizontal and vertical plate member, reinforced by a brace, that securely attaches to the pallet rack, maintaining a predetermined distance for pallets to prevent overhang and ensure uniform placement, featuring a double-walled construction for rigidity and a U-shaped rib for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prior art backstops are used to prevent pallet overhang, then pallet positioning is limited, but the backstops are prone to bending and wear rendering them ineffective
Solution Approach 1:
The invention transitions from a single vertical backstop member to a bracket assembly with both vertical and horizontal plate members, distributing the load across multiple dimensions and attachment points, thereby preventing bending while maintaining positioning effectiveness
Solution Approach 2:
The backstop function is segmented into multiple components: vertical plate member for positioning, horizontal plate member for structural support, and multiple attachment points (front and rear portions), where each segment performs a specific function to collectively achieve reliable and durable pallet positioning
2Productivity
If mechanical equipment places pallets on shelving, then pallet placement efficiency is improved, but incorrect positioning may occur due to operator visibility limitations
Solution Approach 1:
The backstop bracket is pre-installed at the correct position on the shelving system, establishing a predetermined stop point that guides pallet placement. This preliminary positioning reference ensures that even when operators cannot see the rear edges, pallets will be correctly positioned by the physical constraint of the bracket
Solution Approach 2:
The backstop bracket acts as an intermediary between the shelving system and the pallets, providing a physical reference point that mediates the positioning process. The bracket's fixed position and structural features (vertical and horizontal plates) serve as an intermediate guide that ensures accurate pallet placement without requiring operator visibility or judgment
3Area of stationary object
If pallets are positioned close to adjacent walls or structures, then storage space is maximized, but air circulation and fire extinguishing access are obstructed
Solution Approach 1:
The backstop bracket defines and maintains a specific gap distance parameter between pallets and adjacent structures. By establishing this predetermined spacing parameter, the system simultaneously achieves compact storage while ensuring sufficient clearance for air circulation and fire safety, transforming the trade-off into a controlled parameter

AI summary
A backstop bracket which can be removably secured to a support member of a pallet rack limits the distance a load can travel along the pallet rack. When installed on the support member of the pallet rack, the bracket allows for uniform pallet placement on the pallet rack and maintains a predetermined distance between the load on the pallet rack and an adjacent structure, for example, another pallet rack, a wall or a column, to define a vertical flue space for air circulation and fire prevention purposes. The bracket is preferably formed of steel or other suitable metal or, in the alternative, can comprise an elastomeric material including a high impact plastic.
