Omega-Folded Closing Element for Nonwoven Fastener Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing reclosable absorbent sanitary articles face issues with exposed surface fastening elements that stick to fabrics during manufacturing, packaging, and use, and require complex production processes with multiple closing elements.
Innovation Solution
A closing element with a non-woven web folded into an omega shape, featuring surface fastening elements enclosed between flaps, preventing exposure and simplifying the production process by integrating the fastening elements within the waistband.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If surface fastening elements are applied to the waistband for closing the sanitary article, then the article can be reclosable and easy to fasten, but the fastening elements are exposed and stick to fabrics during manufacturing, packaging, and use
Solution Approach 1:
The closing element is folded into an omega-shaped configuration where the base, intermediate flaps, and distal flaps are nested within each other. The surface fastening elements are located on the distal flaps which are folded back and enclosed by the intermediate flaps, creating a nested structure that hides the fasteners while maintaining their functionality.
Solution Approach 2:
The intermediate flaps act as intermediary elements that separate the surface fastening elements from the external environment. These flaps are permanently fixed to the base and fold back to enclose the distal flaps containing the fastening elements, preventing direct contact with external fabrics while allowing controlled engagement when the article is worn.
2Object-affected harmful factors
If two separate closing elements are applied to each absorbent sanitary article to avoid exposed fasteners, then adhesion problems are reduced, but the production process becomes more complex and time-consuming
Solution Approach 1:
The closing element is divided into functional segments: a base portion attached to the waistband, intermediate flaps that fold back, and distal flaps containing the surface fastening elements. This segmentation allows the fasteners to be enclosed while maintaining a single integrated component that simplifies application to the waistband.
Solution Approach 2:
The base, intermediate flaps, and distal flaps are permanently fixed together as a single integrated closing element. This merging of components into one unit simplifies the production process compared to applying two separate closing elements, while still achieving the goal of enclosing the surface fastening elements to prevent adhesion.
