Absorbent Insert Fastening Pattern for Adjustable Outer-Cover Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-piece absorbent articles face challenges in providing sufficient attachment between the insert and outer cover for a snug and comfortable fit, often requiring additional materials that increase manufacturing costs and environmental impact, while also lacking adjustable fastening properties and maintaining fit during wear.
Innovation Solution
A fastening system with a fastening component and receiving component, where the receiving component covers at least 50% of the surface area, and a macro pattern of fastening elements with varying design elements, surface area, opacity, and spacing, to securely join the absorbent insert to the outer cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If additional materials (e.g., adhesive) are used to provide sufficient attachment between insert and outer cover, then attachment strength is improved, but manufacturing cost and environmental impact increase
Solution Approach 1:
The fastening components and receiving components are integrated directly into the insert and outer cover structures, eliminating the need for separate adhesive materials. The fastening elements are formed as part of the existing article components, merging the attachment function with the structural elements already present in the absorbent article.
Solution Approach 2:
The patent extracts the attachment function from adhesive materials and implements it through mechanical fastening components (hooks, loops, buttons, snaps) that are built into the article structure. This removes the dependency on additional adhesive substances while maintaining attachment strength.
2Quantity of substance
If buttons, slot/loops, or other fastening systems are used to reduce material usage, then material consumption is reduced, but ease of adjustment and fit retention are worsened
Solution Approach 1:
The fastening system incorporates adjustable features that allow dynamic modification of the attachment characteristics. The fastening components can be positioned at different locations and configured to provide varying degrees of attachment strength, enabling adjustment to accommodate different wearer needs and activity levels while maintaining secure fit retention.
Solution Approach 2:
Different fastening components are strategically positioned at specific locations on the insert and outer cover to provide localized attachment properties. This allows different regions of the article to have different fastening characteristics, optimizing both adjustability and fit retention in critical areas while minimizing material usage overall.
3Strength
If conventional fastening systems are used, then attachment is provided, but manufacturing complexity increases
Solution Approach 1:
The fastening system is divided into distinct fastening components and receiving components that can be manufactured separately and then integrated into the insert and outer cover. This segmentation allows for specialized manufacturing processes for each component type, simplifying production while providing effective attachment functionality.
Solution Approach 2:
The fastening components are designed to serve multiple functions: providing attachment strength, enabling adjustment, and maintaining fit during wear. By creating multi-functional fastening elements that combine these capabilities, the patent reduces the need for multiple separate components, thereby simplifying manufacturing while achieving comprehensive attachment performance.
