Garment Absorbent Pad Sealing Structure for Leak-Free Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional absorbent garments for bodily fluids, such as sanitary pads and adult briefs, are bulky, unattractive, and prone to leakage, causing discomfort and environmental waste, while existing absorbent pads either restrict fitment options or increase leakage risk through stitching.
Innovation Solution
An absorbent pad design featuring a liquid impermeable barrier layer, a functional layer with a liquid absorbent component, a peripheral sealing element, and a detachable peripheral attaching element that attaches to the garment fabric, minimizing leakage and allowing for comfortable, reusable wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional absorbent garments (adult briefs, sanitary pads) are used to prevent leakage, then protection against bodily fluids is improved, but the garments become bulky and unattractive
Solution Approach 1:
The absorbent pad is divided into multiple functional layers (barrier layer, functional layer with absorbent component, peripheral sealing element) that can be separately optimized. Each layer performs a specific function, allowing the overall structure to be thin yet effective, resolving the contradiction between protection and bulkiness.
Solution Approach 2:
The barrier layer and peripheral sealing element are designed as thin film structures that provide liquid impermeability without adding significant bulk. The peripheral sealing element forms a thin protective barrier around the absorbent component, maintaining a sleek profile while ensuring leak prevention.
2Strength
If stitching is used to attach the absorbent pad to the garment, then attachment strength is improved, but holes are created that increase leakage risk
Solution Approach 1:
The mechanical stitching system is replaced with a bonding system using adhesive or ultrasonic bonding. This substitution eliminates needle holes that would compromise the liquid barrier, while still providing strong attachment through chemical adhesion or thermal bonding mechanisms.
Solution Approach 2:
The barrier layer and peripheral sealing element are designed as continuous thin films that are bonded to the garment without punctures. The bonding method maintains the integrity of the liquid impermeable barrier while providing secure attachment.
3Area of stationary object
If adult briefs are worn to prevent leakage, then protection area is improved, but the garments become difficult to conceal under outer clothing
Solution Approach 1:
The absorbent pad is segmented into thin functional layers that collectively provide extensive protection area while maintaining a thin overall profile. This allows the product to cover a large area for leak prevention without the bulk that would make it visible under clothing.
Solution Approach 2:
The use of thin film barrier layers and sealing elements provides maximum protection area with minimum thickness, enabling the garment to be concealed under outer clothing while still offering comprehensive protection against leakage.
4Ease of operation
If disposable products are used for absorbency, then ease of replacement is improved, but environmental and economic costs increase
Solution Approach 1:
The absorbent pad is designed to be reusable rather than disposable. The barrier layer and peripheral sealing element can be removed, cleaned, and reattached to the same absorbent component, allowing multiple uses before disposal. This recovering approach reduces waste while maintaining ease of replacement by enabling simple cleaning and reattachment.

AI summary
The present disclosure generally relates to an absorbent pad for use in a garment. The absorbent pad includes: a liquid impermeable barrier layer; a functional layer attached to the barrier layer, the functional layer comprising a liquid absorbent component; a liquid impermeable peripheral sealing element bonded to peripheries of the functional layer and barrier layer; and a peripheral attaching element having a first portion and a second portion, the first portion bonded to the peripheral sealing element. The second portion of the peripheral attaching element is detached from the peripheral sealing element and is arranged to be attached to a fabric body of the garment, thereby attaching the absorbent pad to the garment.
