Box Structure With Lower Walls for Easier Article Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is difficult to easily remove an article from a box when its outer surface is in contact with the inner surface of the box.
Innovation Solution
A box design with a storage section and a lid section, where the lid section has a top plate and a first circumferential wall connected via a crease, and a second circumferential wall lower in height, allowing the lid to be opened at an angle greater than 90 degrees, and a supported surface below the top plate to prevent interference with the article.

Engineering Contradiction Analysis
1Ease of operation
If the article is stored inside the box with its outer surface in contact with the inner surface of the box, then the box can provide structural support and protection, but it becomes difficult to take out the article from the box
Solution Approach 1:
The box is segmented into two distinct circumferential wall sections with different heights. The first circumferential wall section (higher) provides structural support, while the second circumferential wall section (lower) creates a clearance zone that facilitates easy article removal. This segmentation allows different parts of the box to serve different functions simultaneously.
Solution Approach 2:
Different regions of the box's inner surface have different heights locally. The area around the second circumferential wall section provides a lower height region that creates clearance between the article and the box's inner surface, making it easier to remove the article without compromising the overall structural integrity provided by the higher first circumferential wall section.
2Ease of operation
If the box is designed with a simple flat plate structure, then manufacturing cost is reduced, but the box cannot provide sufficient clearance for easy article removal
Solution Approach 1:
The flat plate structure is segmented into regions that form the first and second circumferential wall sections with different heights when folded. This segmentation can be achieved through crease lines and fold patterns in the flat plate, allowing the box to provide clearance for easy article removal while still being manufactured from a single flat plate, maintaining cost-effectiveness.
3Ease of operation
If the lid section is designed to open at an angle greater than 90 degrees, then article accessibility is improved, but the box's structural integrity may be compromised
Solution Approach 1:
The lid section is connected to the box body through a hinge structure that allows it to open at an angle greater than 90 degrees. The segmentation of the box into higher and lower wall sections ensures that even when the lid is fully open, the higher first circumferential wall section maintains the box's structural integrity and stability.

AI summary
Provided is a box from which an article stored inside the box can be easily taken out and a box material that can form the box. A lid section (10) of a box (1) has a first circumferential wall section (12) that surrounds a top plate section (11). A storage section (20) of the box has a second circumferential wall section (22) that surrounds a bottom plate section (21). The first circumferential wall section of the storage section is lower in height than the first circumferential wall section of the lid section. The lid section has a supported surface (14A) that is arranged below the top plate section and is supported by an upper end of the second circumferential wall section in a state where the lid section is closed.
