Wave-Shaped Crease Packaging Blank
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging solutions lack the ability to be customized for specific items, leading to inefficiencies in packaging and shipping, such as unnecessary space usage and potential damage to items during transit.
Innovation Solution
A method for customizing a blank of cardboard or corrugated cardboard by creating wave-shaped crease lines with straight crease tracts, allowing the material to be folded into a package with undulated panels that provide enhanced resistance and interlocking capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional flat packaging blanks are used, then manufacturing and folding are simple, but the packages lack resistance to external stresses and provide insufficient protection for items
Solution Approach 1:
The patent applies curvature by replacing straight crease lines with wave-shaped crease lines in the packaging blank. This creates undulated panels that provide structural strength and resistance to external stresses while maintaining the ability to fold into a functional package. The wave-shaped creases create a corrugated effect that enhances protective capabilities without requiring additional materials.
2Adaptability or versatility
If standardized package sizes are used, then production is efficient, but the packages do not fit specific items properly leading to wasted space
Solution Approach 1:
The patent enables parameter changes by allowing the dimensions and spacing of wave-shaped crease lines to be adjusted based on the specific item being packaged. The distance between wave creases and the amplitude of waves can be modified to create custom-fit packages, optimizing space utilization while maintaining production efficiency through a standardized customization process.
3Reliability
If excessive packaging material is used, then item protection is improved, but space requirements and waste increase
Solution Approach 1:
The patent applies segmentation by dividing the packaging blank into multiple panels separated by wave-shaped crease lines. This creates distinct functional zones (side panels, top panels, bottom panels) that work together to provide protection. The segmented structure achieves reliable item protection through the collective action of multiple creased panels rather than requiring excessive single-layer material or additional dunnage.

AI summary
A method for customizing a blank of sheet material delimited by first and second opposite sides and third and fourth opposite sides orthogonal to the first and second sides involves doing, on a face of the blank, a first couple of first and second wave-shaped crease lines and a second couple of third and fourth wave-shaped crease lines, each wave-shaped crease line being crossed by straight crease tracts, so that the third side, the first, second, third and fourth wave-shaped crease lines and fourth side delimit in succession a first top panel, a first side panel, a bottom panel, a second side panel and a second top panel, doing first and second continuous straight crease lines parallel to each other and to the straight crease tracts and delimiting respective back and front wings of each of the first top panel, first side panel, bottom panel, second side panel and second top panel. Glue is transversally applied to the straight crease lines.
