Garment Wetness Detection System for Leakage Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorbent articles, such as diapers and incontinence products, often leak due to various factors, making it difficult to determine the location and timing of leakage, especially in young wearers, and current moisture indicators do not effectively detect leakage from the absorbent article itself.
Innovation Solution
A garment with a wetness detection system that includes multiple wetness detection mechanisms at specific zones on the substrate, configured to detect wetness electronically, and a controller to record and communicate the location and timing of leakage, allowing for timely detection and notification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If passive wetness indicators (indicator strips, printing) are used in absorbent articles, then wetness can be indicated, but the location and timing of leakage from the absorbent article itself cannot be effectively detected
Solution Approach 1:
The garment is divided into multiple detection zones with separate wetness detection mechanisms positioned at specific locations (front, rear, sides). Each mechanism independently monitors its zone, enabling precise localization of leakage sources and timing detection without requiring modification to the absorbent article structure.
Solution Approach 2:
The garment serves as an intermediary layer between the absorbent article and the detection system. Wetness detection mechanisms in the garment detect leakage indirectly through the garment substrate, providing accurate location and timing information without requiring direct contact with or modification of the absorbent article.
2Reliability
If sensors in bed mats are used to detect leakage, then wetness can be detected, but significant delay occurs due to additional layers that body exudates must pass through
Solution Approach 1:
The wetness detection mechanisms are positioned in the garment layer that is in direct contact with or adjacent to the absorbent article, before exudates reach deeper layers or bedding. This preliminary detection position enables immediate detection of leakage as it occurs, eliminating the time delay associated with exudates penetrating multiple layers to reach bed mat sensors.
3Loss of information
If visual inspection of the absorbent article is performed to determine leakage, then leakage can be identified, but it is difficult to determine location and timing especially in young wearers
Solution Approach 1:
The system provides automatic feedback through the controller when wetness is detected by any detection mechanism. The controller processes signals from multiple zones and provides immediate notification of leakage location and timing, eliminating the need for manual visual inspection and providing objective, timely information to caregivers.
Solution Approach 2:
The detection system operates autonomously without requiring manual inspection. The wetness detection mechanisms continuously monitor their zones, and the controller automatically processes detection data and provides information about leakage events, making the system self-sufficient and eliminating the burden of visual inspection on caregivers.
4Measurement precision
If multiple wetness detection mechanisms are disposed at different detection zones on the substrate, then location and timing of leakage can be detected, but device complexity increases
Solution Approach 1:
The controller serves multiple functions: receiving signals from multiple detection mechanisms, determining leakage location based on which zone is wet, recording timing information, and providing notifications. This multi-functionality consolidates what would otherwise require separate components into a single device, maintaining precision while managing complexity.
Solution Approach 2:
Multiple wetness detection mechanisms are integrated into a single unified detection system with a common controller. The detection zones are merged into a coordinated monitoring network where the controller processes information from all zones collectively, enabling precise location determination through pattern recognition rather than requiring independent analysis of each sensor.
