Packaging Material Crease Lines for Controlled Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging materials face challenges in forming complex package shapes, particularly when crease lines are close together, leading to difficulties in controlling the folding process and risking misformation of packages.
Innovation Solution
The packaging material incorporates a set of crease lines where the first crease line is configured to fold easier than the adjacent second crease line, with the first crease line being compressed to a greater extent and having a greater width, allowing for controlled folding and accurate formation of package corners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance between two adjacent crease lines is decreased to form complex package shapes, then the package design versatility is improved, but the folding process becomes difficult to control and misformation risk increases
Solution Approach 1:
The patent applies local quality by differentiating the properties of adjacent crease lines. Specifically, the first crease line is compressed to a greater extent than the second crease line, creating localized variations in foldability. This allows the packaging material to have different folding characteristics at different locations, enabling complex package shapes while maintaining controlled folding behavior through the differentiated crease line properties
Solution Approach 2:
The patent changes physical parameters of the crease lines by varying the compression extent. The first crease line is compressed more than the second crease line, creating differences in width and foldability parameters. This parameter variation allows closely spaced crease lines to be differentiated in their folding behavior, resolving the conflict between design versatility and folding control reliability
2Ease of operation
If one fold occurs along an unintended crease line, then the forming sequence is disrupted, but the final package shape becomes incorrect
Solution Approach 1:
The patent applies preliminary anti-action by pre-configuring the crease lines with different compression levels before the folding process. The first crease line is pre-compressed to a greater extent than the second, creating a predetermined foldability hierarchy. This preliminary differentiation prevents unintended folding by making the correct fold path energetically favorable before the forming process begins
Solution Approach 2:
The patent performs preliminary action by creating differentiated crease lines through selective compression during manufacturing. The varying compression extents are established in advance, preparing the packaging material with built-in folding guidance. This preliminary configuration ensures that during the forming process, folds occur along the intended crease lines in the correct sequence, maintaining both operational ease and manufacturing precision

Function Achieved in This Case
This solution ensures correct folding and formation of packages even with closely spaced crease lines, reducing the risk of misformation and enabling the production of packages with precise corner surfaces, improving both aesthetics and gripping functionality.
Implementation Method 1
The set of crease lines may be formed by compressing the packaging material. The first crease line may be compressed to a greater extent than the adjacent second crease line

AI summary
A packaging material is provided, comprising a set of crease lines (10, 10') along which the packaging material is intended to be folded in order to form a package. The set of crease lines (10, 10') comprises at least one first crease line (10a, 10'a) being configured to fold easier than an adjacent second crease line (10b, 10'b). The said crease lines are intended to define a corner surface of the package.
