Rear Refastenable Seal for Disposable Undergarments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable absorbent pants with refastenable seals are uncomfortable and prone to misalignment or injury due to the placement of seals at side or front parts, which are subject to bending and stress during user movements.
Innovation Solution
The refastenable seal is placed at the rear part of the pant, between the side flanks and longitudinal rear edges of the chassis, with front panels wider than rear panels, utilizing a hook & loop type mechanical fastening system to ensure comfort and safety by avoiding stress and bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the refastenable seal is placed at the side or front parts of the pant, then the pant can be refastened and adjusted, but the seal becomes subject to bending and stress during user movements causing misalignment or detachment
Solution Approach 1:
The patent inverts the conventional placement of refastenable seals from the front/side parts of the pant to the rear part. By placing the seals at the rear, the invention eliminates the bending and stress problems that occur at front/side placements during user movements, while still maintaining the refastening capability through the hook-and-loop fastening system positioned between the side flanks and longitudinal rear edges of the chassis.
2Ease of operation
If the refastenable seal is placed at the side or front parts of the pant, then the pant can be opened and closed for verification or readjustment, but the seal may cause discomfort or injury to the user during movements
Solution Approach 1:
The patent relocates the refastenable seal from the front/side placement to the rear placement, thereby removing the source of user discomfort and injury risk. The rear placement ensures that the seal is not in the path of body movements such as bending or sitting, eliminating the harmful effects while preserving the readjustment function through the hook-and-loop fastening system.
3Strength
If front and rear panels are permanently joined to form the pant structure, then the pant maintains structural integrity, but the seal placement becomes fixed and vulnerable to movement-induced stress
Solution Approach 1:
The patent maintains the permanent joining of front and rear panels for structural integrity, but inverts the seal placement from front/side to rear. This inversion allows the seal to be positioned in an area that experiences minimal stress and bending during user movements, thereby maintaining both structural integrity and seal alignment stability simultaneously.
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 provides a comfortable and safe disposable absorbent pant that maintains seal integrity and user safety by placing the refastenable seal at the rear, reducing discomfort and risk of injury from seal misalignment or detachment.
Implementation Method 1
a refastenable fastening system for joining the left front side panel with the left rear side panel, and the right front side panel with the left front side panel

AI summary
The present invention protects a refastenable disposable absorbent pant, comprised by a chassis, left and right front side panels, and left and right rear side panels, in such a way that the left and right front side panels are joined to the left and right rear side panels, respectively, by means of a refastenable seal, such that the pant has an arrangement suitable to be pulled up and down through the legs, with a waist opening and a pair of leg openings, such that the left and right front panels are wider than the left and right rear panels, and the refastenable seal is placed at the rear part of the pant, between the side flanks thereof and the longitudinal edges of the chassis.
