Side Panels for Absorbent Articles with Hip-Level Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorbent articles, such as disposable diapers and incontinence briefs, tend to slip off users due to inadequate fastening systems, which fail to securely maintain the product around the waist, especially during movement, leading to discomfort and potential chafing.
Innovation Solution
The design incorporates side panels that extend beyond the waistline edge, secured above the hip joints, with a fastening device and elastic portions to distribute load evenly, preventing slipping and enhancing wearability by acting as a suspension bridge to manage movement-induced torque.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If side panels are secured at the hip joint, then the fastening system is simple, but the article slips off during movement
Solution Approach 1:
The side panels extend beyond the traditional hip joint level to engage with the waistline, adding a vertical dimension to the fastening system. This dimensional extension allows the panels to anchor the article higher on the body, preventing slippage during movement while maintaining fastening security.
Solution Approach 2:
An elastic portion is introduced as an intermediary element between the side panel and the user's waist. This elastic component acts as a mediator that distributes fastening forces evenly across the waistline, enhancing security while accommodating body movements without requiring complex adjustment mechanisms.
2Reliability
If fasteners are positioned at the hip joint, then the fastening system is simple, but torque from movement loosens hooks from nonwoven
Solution Approach 1:
The fastening system is repositioned from the horizontal hip joint level to the vertical waistline level. This dimensional shift moves the fasteners away from the high-torque hip joint area, reducing the rotational forces that cause hooks to detach from the nonwoven material during movement.
Solution Approach 2:
The elastic portion changes the mechanical parameters of the fastening system by introducing flexibility and elasticity. This allows the fastening system to dynamically adjust to body movements, distributing and reducing the torque forces transmitted to the hooks and nonwoven material.
3Reliability
If side panels extend beyond waistline, then the article remains secure during movement, but the side panels are longer
Solution Approach 1:
The side panels exhibit local quality variation with different functional zones: a rigid portion for structural support and attachment, and an elastic portion for flexible engagement. This localized differentiation allows the panels to extend beyond the waistline for enhanced security while managing the implications of increased length through functional segmentation.
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
The solution effectively secures the absorbent article above the hip joint, preventing slipping and reducing torque on fasteners, thereby ensuring a more comfortable and secure fit, even during movement.
Implementation Method 1
The side panels include an elastic portion. The elastic portion has an elastic elongation of 20% to 250%

AI summary
An absorbent article includes side panels for securing around the waist of the user. The absorbent article includes a first end, a second end, and an absorbent section therebetween. The first end has longitudinal side edges and a first waist line edge. A pair of side panels extend from longitudinal side edges of said first end of the absorbent article, and are shaped and dimensioned so as extend beyond the first waist line edge of the first end of the absorbent article a longitudinal extent so that the side panels may be secured above the hip joints of the user.
