Folded Incontinence Article Closure Tabs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
At high production speeds, incontinence articles with attached diaper ears often have closure elements that unintentionally open, leading to impaired product quality and unusability due to unwanted fixation with other material layers during the manufacturing and packaging processes.
Innovation Solution
The incontinence article is designed with rear material sections folded inwardly onto the body-facing side of the main part, with closure element tabs folded back onto the inside, and additional gripping areas for easy user recognition and unfolding, using pressure-sensitive adhesive or mechanical closure aids like Velcro hooks, and nonwoven materials with embossed patterns for strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If production speed is increased, then productivity is improved, but manufacturing precision deteriorates due to unintentional opening of closure elements
Solution Approach 1:
The closure element tabs are folded back onto the inside of the material sections before the main folding operation. This preliminary action positions the closure elements in a protected state during high-speed production, preventing unintentional opening while maintaining precision for subsequent closure functionality.
Solution Approach 2:
The closure element tabs are nested within the folded material sections, with the tabs folded back onto the inside surface. This nesting protects the closure elements from draft forces during production while maintaining their functionality for later closure operation.
2Productivity
If production speed is increased, then productivity is improved, but product quality deteriorates due to unwanted fixation with material layers
Solution Approach 1:
By folding the closure element tabs back onto the inside before the main folding operation, the closure elements are positioned away from other material layers. This preliminary action prevents unwanted fixation during high-speed production while maintaining reliability for intended closure functionality.
Solution Approach 2:
The closure element tabs are extracted from the outer surface and folded onto the inside surface of the material sections. This extraction removes them from the path of draft forces and other material layers during production, preventing unwanted fixation while preserving their closure function.
3Manufacturing precision
If closure elements are folded back onto the inside, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The material sections are divided into distinct areas: the closure element tabs folded back onto the inside, and the main body folded in the conventional manner. This segmentation allows precise positioning of closure elements while maintaining a relatively simple overall folding structure that can be implemented at high speeds.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design protects closure elements from draft forces during production, ensuring they remain functional and the articles can be easily unfolded and used, maintaining product quality even at high production speeds.
Implementation Method 1
the closure element tabs can have, for example, a pressure-sensitive adhesive zone
