Expandable Packaging Container for Efficient Item Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cardboard boxes often have unused space, making it difficult to efficiently pack and remove items, especially in smaller boxes where items are tightly packed and hard to access.
Innovation Solution
A container with expandable portions that allow for a smaller size configuration for shipping and storage, and a larger size configuration for easy item removal, achieved through the use of tape that can be cut to expand the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If smaller sized cardboard boxes are used to reduce shipping costs and maximize space utilization, then shipping costs are reduced and space utilization is improved, but item removal becomes difficult and troublesome
Solution Approach 1:
The box incorporates expandable portions that allow the box to dynamically change its size. The box starts in a compact first configuration for shipping, then can be expanded to a larger second configuration for easy item removal. This dynamic transformation resolves the contradiction by allowing the box to have small volume during transport and large volume during unloading.
Solution Approach 2:
The box utilizes parameter changes in its physical dimensions through the expandable portions. By changing the expansion parameter (from collapsed to expanded state), the box transitions between two volume states, enabling both efficient shipping and easy item removal without compromise.
2Ease of operation
If larger sized cardboard boxes are used to facilitate item removal, then item removal becomes easier, but shipping costs increase and storage space is wasted
Solution Approach 1:
The box is designed with expandable portions that enable it to transition from a compact shipping configuration to an expanded unloading configuration. This dynamic capability allows the box to maintain small volume during shipping to reduce costs, then expand to provide easy access for item removal.
Solution Approach 2:
The physical parameter of box volume is made variable through the expandable portions. The box volume parameter changes from a smaller first volume during shipping to a larger second volume during item removal, resolving the contradiction between shipping efficiency and ease of unloading.
3Productivity
If items are tightly packed to maximize space utilization, then shipping efficiency is improved, but item access and removal becomes difficult
Solution Approach 1:
The expandable portions enable the box to transition from a compact tightly-packed configuration optimized for shipping efficiency to an expanded configuration that provides easy access to items. The dynamic size change allows both tight packing and easy access without compromise.
4Reliability
If filler materials are used to fill unused space and prevent item movement, then item protection is improved, but shipping costs increase and space utilization decreases
Solution Approach 1:
The box with expandable portions provides a dynamic solution where the box itself adapts to the item volume rather than requiring static filler materials. The box can be configured to match the item size, eliminating the need for filler materials while maintaining item protection through proper fitting.

AI summary
A container may include one or more walls and one or more expandable portions. For example, a container may include four walls and a first expandable portion may be movable between a collapsed position and an expanded position. The container may also include a second expandable portion that is movable between a collapsed position and an expanded position. The first and second expandable portions may allow a wall of the container to move between a first position and a second position when the first and second expandable portions are moved between the collapsed position and the expanded position.
