Storage Box Side Wall Perforations for Arm Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional storage boxes do not facilitate easy retrieval of objects with handhold portions due to small gaps between the object and the side walls, making it difficult for users to grasp and remove items, especially when the gaps are narrower than the user's arm thickness.
Innovation Solution
The storage box design incorporates perforated or fold lines on the lid and side walls that allow for outward bending, creating larger spaces by forming holes or cuts, enabling users to insert their arms and grasp handhold portions more easily.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the storage box uses a compact design with the object tightly fitted between side walls, then the storage efficiency and space utilization are improved, but the gap between the object and side walls becomes too small for users to insert their arms and grasp handhold portions
Solution Approach 1:
The side walls are segmented with first lines (perforated lines or fold lines) that divide the wall structure into sections, allowing the upper portion to be separated or bent outward independently. This segmentation enables the gap to be enlarged only where needed for arm insertion, while maintaining the compact overall structure for efficient storage.
Solution Approach 2:
The side walls are designed with fold lines that enable dynamic transformation from a fixed compact state to an expanded state with larger gaps. When users need to retrieve objects, they can bend the side walls outward along the fold lines to create sufficient space for arm insertion, then return to the compact state after retrieval.
2Strength
If the storage box maintains rigid side walls for structural strength, then the box durability is improved, but the gaps remain fixed and too narrow for user access
Solution Approach 1:
The side walls are divided into multiple sections by first lines, with the lower portion maintaining rigid structure for strength and the upper portion being flexible for access. This segmentation allows different parts of the side wall to serve different functions - structural support and user interaction.
Solution Approach 2:
Different portions of the side wall have different properties: the lower portion near the bottom edge maintains rigidity and full height for structural strength, while the upper portion near the top edge is made flexible with fold lines to enable bending for user access. Each part has optimized quality for its specific function.
3Ease of operation
If the storage box uses perforated lines for side wall bending, then the ease of expanding gaps is improved, but the manufacturing complexity increases
Solution Approach 1:
The side walls incorporate perforated lines that pre-define the bending locations. These perforations guide users to bend the walls at precise positions to create adequate gaps, while the regular pattern of perforations allows for straightforward manufacturing using standard punching or drilling equipment.

AI summary
A storage box includes a box body that includes a bottom wall and plural side walls including a pair of side walls that oppose each other, the box body having an opening at the top and containing an object, and a pair of lid walls that extend upward from top edges of the pair of side walls and are bent along the top edges so as to cover the opening of the box body. A pair of first lines are formed on the pair of lid walls and the pair of side walls, each first line extending at least partway from a top edge of the corresponding lid wall to a bottom edge of the corresponding side wall and facilitating outward bending of the corresponding side wall when an arm is inserted between the object contained in the box body and the corresponding side wall.
