Undergarment Liner With Perforated Adhesive Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current undergarment liners are not effective in preventing bodily fluid leakage across anatomical differences and cause discomfort, lack versatility, and are not suitable for various clothing types, leading to emotional distress.
Innovation Solution
An undergarment liner design comprising a top layer, absorption layer, bottom layer, and garment adhesive layer, with optional perforation lines for customization, and an outer layer defining the perimeter, using materials like woven cotton, hydro-activated gels, and desiccants for enhanced absorption and ventilation, along with indicators for leakage detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bulky materials are used as a barrier between the body and the undergarment, then leakage protection is improved, but comfort deteriorates and visibility increases
Solution Approach 1:
The patent employs thin film-like absorbent layers and barrier materials that provide leakage protection without the bulk of traditional materials. The liner uses thin, flexible polyethylene or polypropylene barrier layers that conform to the body and undergarment while maintaining protection, eliminating the need for thick padding.
Solution Approach 2:
The liner combines multiple materials with complementary properties: absorbent layers for fluid uptake, barrier layers for leakage prevention, and adhesive layers for secure attachment. This composite structure achieves effective protection with a thin, comfortable profile by leveraging the strengths of each material type.
2Reliability
If purpose-specific undergarment liners are designed, then effectiveness for a particular use case is improved, but versatility deteriorates
Solution Approach 1:
The liner is designed with universal dimensions and features that make it suitable for both male and female anatomies and multiple undergarment types. The absorbent area is positioned to accommodate different anatomical regions, and the overall design works with various clothing styles including swimwear, sportswear, and everyday underwear.
Solution Approach 2:
The liner concentrates absorbent materials in specific zones where fluid leakage is most likely to occur, rather than uniformly distributing thickness throughout. This localized approach provides effective protection for both male and female anatomies while keeping the overall liner thin and adaptable to different undergarment types.
3Ease of operation
If the undergarment liner is made thin and flat, then comfort and invisibility are improved, but absorption capacity may deteriorate
Solution Approach 1:
The absorbent layers utilize porous materials with high surface area to volume ratios, such as cellulose wadding or synthetic absorbent polymers. These materials provide substantial absorption capacity within a thin profile by capturing fluid throughout their porous structure rather than requiring thick layers.
Solution Approach 2:
The liner employs a composite structure with multiple thin absorbent layers that work together to achieve the required absorption capacity. Each layer contributes to the overall absorption, and the layered construction allows fluid to be distributed and absorbed throughout the thickness of the liner, maximizing capacity within a thin form factor.

AI summary
An embodiment of the undergarment can include an undergarment liner comprising a top layer; a bottom layer; an absorption layer; and a garment adhesive layer. The top layer can be oriented as the upper most layer and is the layer that comes in contact with the wearer of the liner. The absorption layer is oriented between the top layer and the bottom layer. The garment adhesive layer can comprise a coupling surface and an adhesion surface. The coupling surface opposes adhesion surface. The undergarment liner also comprises a first perforation line that extends through each layer and subdivides the undergarment liner into a plurality of subsections.
