Multilayer Clothing Lining for Fluid Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for managing body fluids, such as sweat, blood, and menstrual fluids, are not practical for everyday use and often require frequent reapplication, with disposal posing additional technical challenges, and lack durability and hygiene.
Innovation Solution
A breathable, reusable, multilayer clothing lining with a minimum of four layers, including an antimicrobial layer and a waterproof thermoplastic polyurethane layer for vapor dispersion, which can be sewn or pasted onto garments, providing absorbency, antimicrobial protection, and leak-proofing without chemical treatments, promoting user health and environmental sustainability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If disposable solutions are used for body fluid management, then hygiene is improved, but environmental sustainability and economy deteriorate
Solution Approach 1:
The patent implements a reusable lining that can be washed and sanitized multiple times (up to 60 washes) instead of being disposed of after single use. The antimicrobial layer maintains its effectiveness through repeated washing, allowing the product to be recovered and reused, thereby reducing waste while maintaining hygiene standards.
Solution Approach 2:
The patent inverts the disposable concept by creating an affordable reusable product. The multilayer structure with antimicrobial properties is designed to be cost-effective over multiple uses, replacing the need for expensive or frequent disposable alternatives while maintaining hygiene.
2Reliability
If chemical treatments are applied to enhance antimicrobial properties, then hygiene is improved, but user safety for allergic individuals deteriorates
Solution Approach 1:
The patent applies antimicrobial treatment locally and physically rather than through pervasive chemical treatments. The antimicrobial layer is integrated into the fabric structure, providing protection without requiring chemical agents that could trigger allergic reactions in sensitive users.
Solution Approach 2:
The patent replaces chemical antimicrobial mechanisms with a physical or structural approach. The antimicrobial layer is constructed to provide protection through its material properties and structure rather than through chemical reactions, eliminating the harmful effects of chemicals for allergic individuals.
3Adaptability or versatility
If multiple layers are added to provide comprehensive protection, then functionality is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions (absorbency, antimicrobial protection, vapor dispersion, and waterproofing) into an integrated multilayer structure. Each layer serves a specific function, but they work together as a unified system that can be applied as a single component to garments, reducing the complexity of implementing multiple separate solutions.
Solution Approach 2:
The multilayer lining is designed as a universal solution that provides multiple protective functions simultaneously. The same structure delivers absorbency, antimicrobial protection, vapor dispersion, and leak-proofing, making it a versatile component that can be applied to various garment types without requiring separate specialized layers for each function.
4Loss of substance
If reusable materials are used, then economy and sustainability are improved, but durability through repeated washing deteriorates
Solution Approach 1:
The patent incorporates an antimicrobial layer that is specifically designed to withstand repeated washing cycles (up to 60 washes). The layer is constructed with durable materials and bonding methods that maintain its integrity and antimicrobial effectiveness throughout the product's lifecycle, cushioning against the degradation that normally occurs with repeated washing.
Solution Approach 2:
The patent uses composite material construction where the antimicrobial layer is integrated with the fabric layers through durable bonding. This composite structure combines materials with complementary properties - the fabric provides structural durability while the antimicrobial layer provides functional longevity, ensuring both layers withstand repeated washing without degrading.
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
