Incontinence Pad Fixation Device with Matched Closure Width
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current incontinence pad fixation and carrying devices often fail to securely clamp the incontinence pad in place, leading to liquid leakage and discomfort due to movement, as the material sections can shift and cover the liquid-permeable layer, reducing absorption capacity and causing the pad to be pulled too tightly into the crotch area.
Innovation Solution
A fixation and carrying device with a hip belt that features mechanically and/or adhesively acting closure elements, where the width of the closure elements is matched to the distance between material sections, providing increased rigidity and preventing the incontinence pad from being pulled into the crotch area, while ensuring the closure elements do not chafe or stick to the skin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hip belt is closed on itself in the abdominal area with bib-like attachments, then the incontinence pad can be attached to the side areas, but the material sections can shift and cover the liquid-permeable layer, reducing absorption capacity
Solution Approach 1:
The patent applies parameter changes by matching the width of closure elements to the distance between fixation lines of material sections. This specific dimensional parameter ensures that closure elements provide sufficient rigidity to prevent material section shifting while maintaining the liquid-permeable layer's absorption capacity. The closure element width is carefully selected to create optimal structural support without excessive stiffness.
Solution Approach 2:
The patent employs composite materials by combining the hip belt, bib sections, closure elements, and incontinence pad into an integrated system. The closure elements are mechanically and/or adhesively bonded to both the bib sections and the incontinence pad, creating a composite structure that distributes forces evenly and prevents relative movement between components while maintaining absorption functionality.
2Reliability
If closure elements are used to secure the incontinence pad, then the pad is fixed in place, but the closure elements may chafe or stick to the skin, causing discomfort
Solution Approach 1:
The patent applies local quality by positioning closure elements specifically on the bib sections that extend towards the crotch area, rather than directly on the skin-contacting surfaces of the incontinence pad. The closure elements are placed in areas where they can provide secure fixation while being spatially separated from the user's skin, thus preventing chafing and sticking while maintaining reliable pad fixation.
3Shape
If the incontinence pad is pulled into the crotch area, then the pad moves to the intended position, but the absorption capacity is reduced and comfort is compromised
Solution Approach 1:
The patent applies parameter changes by carefully designing the distance between fixation lines of material sections and matching it to the width of closure elements. This dimensional parameter control ensures that the incontinence pad is held at the optimal position in the crotch area without being pulled too tightly, thereby maintaining both the intended shape and the absorption capacity while ensuring user comfort.
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 device significantly increases the bending stiffness of the incontinence pad, preventing liquid leakage and ensuring even distribution of the pad's absorption capacity, while maintaining comfort by preventing the pad from being pulled too tightly and minimizing contact with the skin.

AI summary
The invention relates to a fastening and carrying device (2) for a disposable, absorbent incontinence pad (4) having a girdle (6), which can be detachably closed on itself by girdle closure elements (22) and thus forms a continuous girdle opening in a girdle circumferential direction (8), to which girdle the incontinence pad (4) can be detachably connected, so that said incontinence pad is worn in the crotch area of the user and can be removed from the girdle (6) after use and discarded, wherein the girdle (6) comprises a front stomach region (14), a rear back region (16) and a left and right side region (18, 20), the girdle (6) has a bib section (32, 34) extending in a longitudinal direction in the direction (38) on the crotch area of the user from the back region (16) and the stomach region (14) which bib section has closure elements (40, 42) on the side thereof facing the body which interact in a detachably adhesive manner with complementary closure elements on the side of the incontinence pad (4) facing away from the body, wherein the incontinence pad (4) has a pair of material sections (58) running in the longitudinal direction of the incontinence pad (4) on the side thereof facing the user which are fastened to the incontinence pad (4) along the one longitudinal edge thereof as a fastening line and which have a second longitudinal edge which is free at least in sections, characterized in that the width of at least one of the closure elements (40, 42) crosswise to the longitudinal direction equals at least 50% of the distance of the fastening lines of the material sections (58) of the incontinence pad (4).
