Dividerless Pallet Packaging With Braced Trays for Stacking Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Palletized packaging systems face challenges in balancing stacking strength and product visibility, as dividers improve stacking but obstruct visibility, and existing systems lack sufficient reinforcement for irregularly shaped or soft-packaged items.
Innovation Solution
A modular packaging system featuring vertically stacked trays with corner posts and separate braces that support the trays, eliminating the need for dividers, providing enhanced load-bearing strength and visibility by using corrugated board for trays and hollow paper tubes for braces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If dividers are used between trays, then stacking strength is improved, but product visibility is reduced
Solution Approach 1:
The packaging system is divided into modular components: trays for holding products, corner posts for structural support, and separate braces for reinforcement. This segmentation allows each component to perform its specific function without interfering with product visibility, as the supports are positioned at corners and edges rather than creating continuous divider walls across the tray openings.
Solution Approach 2:
The reinforcement structure is moved from a two-dimensional divider plane to a three-dimensional corner post configuration with diagonal braces. By placing supports at the corners and using diagonal bracing between trays, the system achieves stacking strength through spatial distribution rather than through blocking views with horizontal dividers.
2Strength
If structural components like corner posts and dividers are used to support trays, then stacking strength is improved, but device complexity increases
Solution Approach 1:
The corner posts serve multiple functions simultaneously: they provide vertical support between trays, act as attachment points for diagonal braces, and define the structural framework for the entire packaging unit. This merging of functions reduces the number of separate components needed compared to systems using both dividers and corner posts.
Solution Approach 2:
The corner posts are designed as universal structural elements that can accommodate various tray configurations and product types. The same corner post design works for different tray sizes and can support both the tray above and the brace structure, reducing the need for specialized components for different applications.
3Strength
If separate braces are added to reinforce trays, then stacking strength is improved, but manufacturing complexity increases
Solution Approach 1:
The diagonal braces are pre-formed as separate components before assembly, allowing for standardized manufacturing of each brace piece. This preliminary preparation enables efficient assembly line production where braces are simply attached to predetermined locations on corner posts, rather than requiring complex on-site construction or customization.

AI summary
A modular packaging system for shipping and displaying palletized products is provided. The packaging system comprises a plurality of vertically stacked trays for holding the products, corner posts extending between vertically adjacent trays for spacing and supporting the trays, and one or more separate elongated braces located under and supporting one or more of the trays. The ends of the braces extend into openings in the corner posts. The system is strong enough not only to support the weight of the products on the trays and withstand the vibration and impact forces that can occur during shipping, but to withstand the weight of one or more units stacked on top.
