Reconfigurable Packaging Box With Shearable Punchings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packing boxes made of rigid or semi-rigid materials are limited to a single fixed shape and size, failing to adapt to varying needs and storage configurations, particularly in deepfreezers with different dimensions, leading to inefficient use of space and potential damage to stored items due to inflexible packaging.
Innovation Solution
The development of boxes made from sheets with strategically arranged punchings that allow for easy folding and shearing, enabling the creation of boxes with varying shapes and sizes, suitable for use in diverse storage environments, including deepfreezers with different dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fixed-shape boxes are used, then manufacturing simplicity is maintained, but adaptability to different storage spaces deteriorates
Solution Approach 1:
The box is divided into multiple modular sections separated by punchings, allowing independent folding and configuration of each section. This segmentation enables the box to adapt to different storage spaces while maintaining a relatively simple overall structure based on standardized modules.
Solution Approach 2:
The box transitions from a fixed rigid structure to a dynamic reconfigurable structure through foldable punchings and movable walls. The punchings can be folded along predetermined lines to change the box's internal configuration, providing adaptability without requiring multiple different box designs.
2Adaptability or versatility
If boxes with multiple configurations are created, then versatility improves, but ease of manufacture deteriorates
Solution Approach 1:
The sheet is pre-divided into standardized modular sections with punchings positioned at regular intervals. This segmentation allows multiple configurations to be achieved from a single sheet without requiring complex custom manufacturing for each configuration.
Solution Approach 2:
The box configurations are achieved by changing the folding parameters of existing punchings rather than creating new structural elements. The same sheet can produce different box sizes and shapes by folding along different punching lines, maintaining manufacturing simplicity while providing versatility.
3Adaptability or versatility
If inflexible box structures are used, then structural strength is maintained, but adaptability to storage needs deteriorates
Solution Approach 1:
The punchings are pre-positioned and pre-scored on the sheet during manufacturing, preparing the structure for future reconfiguration. This preliminary action allows the box to be easily adapted to different storage needs while maintaining structural integrity through predetermined reinforcement zones.
Solution Approach 2:
Different regions of the box have different structural qualities - walls requiring strength are made rigid, while regions needing flexibility contain the foldable punchings. This local differentiation allows the box to provide both strength and adaptability in appropriate locations.

AI summary
Boxes are described that can vary their shape and size according to how the sheets that make them are folded, by virtue of the presence of multiple punchings appropriately arranged, and wherein at least a portion of said punchings is easily sheared, said punched sheets being also described.
