Packaging Perforation Pattern for Adjustable Box Depth and Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional multi-depth boxes require imprecise cutting and uneven depths, leading to potential destruction or unusability, while slotted boxes create undesired openings unless minimum depths are selected, necessitating an improved mechanism for manipulating packaging with enhanced structural strength and separability.
Innovation Solution
A perforation pattern with varying characteristics and skips is applied between columns of packaging panels, allowing for adjustable height and improved folding, bending, and separation, featuring cuts and skips with different characteristics and angles, and optionally including glue tabs for enhanced structural strength and separability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional cutting methods are used to create multi-depth boxes, then box depth can be adjusted, but cutting precision is poor and depths are uneven leading to box destruction or unusability
Solution Approach 1:
The box structure is segmented into multiple depth configurations through pre-defined perforation patterns. Instead of cutting the entire box structure, the invention divides the board into sections separated by perforations, allowing selective removal of panel rows to achieve different depths without compromising overall structural integrity.
Solution Approach 2:
Perforations are created in advance during manufacturing at precise locations that define potential depth boundaries. These pre-positioned perforations enable users to achieve accurate depth adjustments without requiring precise cutting operations, as the critical positioning work has already been done during box fabrication.
2Adaptability or versatility
If slotted boxes are used to allow depth selection, then depth adjustment is possible, but undesired openings are created unless minimum depths are selected
Solution Approach 1:
The board is divided into discrete panel rows separated by perforations rather than continuous slots. This segmentation allows the box to maintain solid walls at selected depths while still enabling depth adjustment, eliminating the harmful effect of unwanted openings that plague slotted box designs.
Solution Approach 2:
The perforation patterns are strategically placed only where needed for depth adjustment, while other areas of the box maintain full structural integrity. This localized approach ensures that openings are created only at specific controlled locations rather than throughout the entire box structure.
3Adaptability or versatility
If perforation patterns are added to enable depth adjustment, then box versatility improves, but structural strength may be compromised
Solution Approach 1:
Perforations are concentrated specifically at panel row boundaries where they are needed for separation, while the majority of the box structure remains solid and unperforated. This localized perforation approach minimizes the impact on overall structural strength while still enabling depth adjustment functionality.
Solution Approach 2:
The box construction utilizes layered board materials with perforations created through specific patterns that maintain composite structural integrity. The combination of solid board material with strategically placed perforations creates a composite structure that balances strength requirements with separability needs.

AI summary
A perforation pattern for packaging is provided with improved folding, bending, and separation of adjacent panels. The packaging that includes the perforation pattern may include a columns, rows, glue tabs, column scores, row scores, perforations, cuts, skips, and bundle breakers. Perforation patterns may be irregular, angled, shifted, or otherwise configured to increase usability, strength, and/or other aspects of the packaging.
