Segmented Peel Strip System for Adhesive Contamination Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing body-adhering absorbent articles face issues with adhesive contamination and errant attachment during the donning process, particularly due to skin oils and lotions, and the flexibility of the product, which can lead to improper positioning and reduced effectiveness.
Innovation Solution
The design incorporates anterior and posterior attachment regions with peel strips that transition from a protected to a fixed donning condition, allowing controlled exposure of the adhesive, minimizing contamination and errant attachment by providing distinct grasping surfaces and reducing exposed adhesive during application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the body adhesive is fully exposed for application, then the donning process is simplified, but adhesive contamination from skin oils and lotions increases
Solution Approach 1:
The adhesive region is divided into multiple segments covered by separate peel strips. Each peel strip can be removed independently to expose only the necessary portion of adhesive for attachment, minimizing exposure time and contamination risk while maintaining ease of application.
Solution Approach 2:
The adhesive is pre-covered by peel strips that are removed just before application. This preliminary protection ensures the adhesive remains clean and uncontaminated until the moment of use, while still allowing for simple donning when the strips are removed.
2Ease of operation
If the peel strip is completely removed to expose the attachment zone, then application is easier, but errant attachment to clothing or improper positioning increases
Solution Approach 1:
The peel strip system is segmented into multiple sections that can be removed progressively. This allows the user to expose only the adhesive portion needed for the current attachment step, reducing the risk of errant attachment to clothing while maintaining ease of application.
Solution Approach 2:
Instead of completely removing all peel strips at once, the system allows for partial removal where only the necessary adhesive regions are exposed. This partial action prevents excessive exposure that could lead to improper positioning or contamination of unused adhesive areas.
3Adaptability or versatility
If the adhesive is exposed early in the donning process, then positioning is more flexible, but contamination from body exudates and lotions increases
Solution Approach 1:
The adhesive regions are preliminarily protected by peel strips that remain in place during the positioning phase. This allows the user to position the article flexibly on the body without exposing the adhesive to contamination, and only reveals the adhesive when the final position is determined.
Solution Approach 2:
The peel strip coverage is dynamic rather than static - it can be adjusted and removed progressively as positioning is finalized. This dynamic approach maintains protection against contamination while allowing positioning flexibility throughout the donning process.

AI summary
An absorbent article has attachment regions having body adhesive. The attachment regions have a protected condition where the body adhesive is fully covered. The attachment regions are adapted to transition from the protected condition to a fixed donning condition where a portion of the body adhesive is exposed and a portion of the body adhesive is covered. The attachment regions are adapted to transition from the fixed donning condition to a fully exposed condition where the body adhesive is fully exposed.
