Wetness Notification System with Urinalysis Sampling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wetness notification systems for clothing articles, such as diapers, lack features for urine sampling and urinalysis, and do not provide low battery notification mechanisms, leading to potential skin allergies and rashes due to untimely changes and increased labor costs from sewing electrodes.
Innovation Solution
A wetness notification system comprising a detecting unit with a moisture detector, wireless transmitter, and sampling unit for urinalysis, along with a clip unit for secure attachment and a receiver unit for wireless notification, including a battery detector to prevent low electricity notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If strip electrodes are sewn into the diaper to enable wetness detection, then wetness notification function is achieved, but labor costs increase and defective products may rise
Solution Approach 1:
The patent extracts the electrode assembly from the sewing process and integrates it into a modular detection device that clips onto the clothing article. The detection device includes electrodes, a moisture detector, and wireless transmitter as separate components that can be easily attached and removed without sewing operations, thereby reducing labor costs and manufacturing defects while maintaining wetness detection reliability.
Solution Approach 2:
The patent replaces the mechanical sewing process with a clipping mechanism. The detection device is designed to clip onto the clothing article using a clip unit with a resilient arm that engages with a positioning member, eliminating the need for sewing operations and associated labor costs and defects.
2Reliability
If conventional wetness notification system is used without urine sampling capability, then basic wetness detection is provided, but early diagnosis of diseases cannot be achieved
Solution Approach 1:
The patent integrates multiple functions into a single detection device: wetness detection via moisture detector, urine sampling via sampling elements, and wireless notification. The detection device can simultaneously perform basic wetness notification and advanced health monitoring through urinalysis, enabling early diagnosis of diseases while maintaining reliable wetness detection.
Solution Approach 2:
The patent extends the monitoring capability by analyzing multiple parameters in the urine sample, including concentration of substances such as proteins, nitrite, glucose, ketones, bilirubin, occult blood, leukocytes, urobilinogen, and physical or chemical properties such as specific gravity and pH value. This multi-parameter analysis enables comprehensive health monitoring and early disease diagnosis.
3Ease of operation
If battery-powered electrical detection device is used for wetness notification, then notification function is achieved, but low battery notification mechanism is absent leading to untimely changes
Solution Approach 1:
The patent implements a feedback mechanism where the processor continuously monitors battery power levels and automatically generates low battery notification signals when the battery power falls below a threshold. This feedback loop ensures that both wetness and low battery conditions are promptly notified, maintaining continuous system reliability and preventing untimely changes.

Implementation Method 1
A first side of the first non-woven fabric layer absorbs a liquid excreted from a human body, and the liquid permeates to a second side of the first non-woven fabric layer
Implementation Method 2
The liquid absorbing layer is attached to the second side of the second non-woven fabric layer, and absorbs that liquid permeated through the second non-woven fabric layer
Implementation Method 3
a wireless transmitter disposed in the casing, a processor disposed in the casing, electrically connected to the moisture detector and the wireless transmitter, and configured to receive the notification signal outputted by the moisture detector and to transmit the notification signal through the wireless transmitter
