Corrugated Cardboard Compartmented Packaging System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging methods for online grocery shipping, such as corrugated boxes with dunnage, fail to effectively protect items of disparate shapes, sizes, and densities, leading to damage during transit, especially when heavier items crush lighter ones.
Innovation Solution
A packaging system using corrugated cardboard components that divide the box into customizable compartments, allowing for configuration into two to four rectangular compartments, with horizontal and vertical dividers that can be reconfigured to accommodate various load patterns, providing independent load-bearing capabilities for each item.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a single corrugated box with dunnage is used to ship grocery items, then shipping cost is reduced, but items of disparate shapes, sizes, and densities cannot be adequately protected from each other
Solution Approach 1:
The box interior is segmented into multiple compartments using vertical and horizontal dividers made of corrugated cardboard. These dividers create separate weight-bearing compartments that isolate items from each other, preventing damage while maintaining a single-box shipping model that reduces shipping costs.
Solution Approach 2:
Each compartment is designed with specific load-bearing characteristics tailored to the items it contains. The dividers create localized protection zones where each item or group of items receives customized support based on its weight, shape, and density requirements.
2Productivity
If heavy items are placed at the bottom and light items at the top of a single box, then packing efficiency is improved, but light items are crushed when the box orientation changes during shipping
Solution Approach 1:
The box is divided into multiple weight-bearing compartments using vertical and horizontal dividers. Each compartment independently supports the weight of items placed within it, eliminating the crushing problem that occurs when heavy and light items are stacked in a single compartment and the box orientation changes.
Solution Approach 2:
The corrugated cardboard dividers are positioned beforehand to create rigid barriers between items of different weights. These dividers act as pre-positioned protective structures that prevent weight transfer from heavy to light items regardless of box orientation during shipping.
3Reliability
If a compartmented insert is used to protect items, then item isolation is improved, but the system becomes complex and difficult to configure for different load patterns
Solution Approach 1:
The divider system is designed to be dynamically reconfigurable. Vertical and horizontal dividers can be easily positioned and adjusted to create different compartment configurations based on the specific load pattern and item dimensions, allowing the same basic structure to adapt to various shipping scenarios without requiring completely different insert designs.
Solution Approach 2:
The corrugated cardboard dividers serve multiple functions: they create compartment boundaries, provide weight-bearing support, and can be configured in various patterns. This universal component design eliminates the need for specialized inserts for different load patterns, reducing overall system complexity.

AI summary
A packaging system for a corrugated cardboard shipping container. The system uses two vertical compartmented inserts divided by a horizontal insert. The compartmented insert can be configured by a packer to consist of four to two rectangular compartments. The horizontal insert can be folded in half or have a quarter section folded away in order to accommodate a loading plan that requires items to protrude above the height of the bottom vertical compartmented insert. An optional diagonal divider and dunnage may be used prior to sealing the container.
