Incontinence Detection System Using Wetness Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for managing urinary incontinence in non-ambulatory or compromised patients are inefficient due to a lack of real-time information on void events, leading to prolonged wear of wet or soiled briefs, which increases the risk of urinary tract infections and discomfort.
Innovation Solution
An incontinence monitoring system with a low-cost wetness sensor embedded in briefs that sends timely notifications to caregivers via a reusable tag, allowing for immediate brief changes and reducing the duration of wearing a wet or soiled brief.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If brief changes are based on a time schedule, then caregivers can manage brief changes systematically, but they lack real-time information about actual void events leading to delayed changes
Solution Approach 1:
The patent implements a feedback mechanism where wetness sensors embedded in the brief continuously monitor moisture levels and transmit real-time data to caregivers. This feedback loop enables caregivers to respond immediately to actual void events rather than relying on predetermined schedules, directly resolving the information loss problem and reducing the time patients wear wet briefs.
Solution Approach 2:
The brief itself performs the monitoring function through embedded wetness sensors, eliminating the need for continuous manual inspection by caregivers. The brief autonomously detects void events and communicates status, allowing the system to self-monitor without constant human intervention while providing timely alerts for changing.
2Reliability
If wetness sensors are embedded in disposable briefs, then real-time monitoring is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent integrates wetness sensors into disposable briefs, making the sensing component single-use along with the brief itself. This approach accepts the brief as a short-lived object that can be manufactured with embedded sensors at low cost, eliminating the need for expensive reusable sensor systems while maintaining reliable real-time detection throughout the brief's usage life.
Solution Approach 2:
The patent combines the wetness sensing function with the brief structure itself, merging two separate components (sensor and brief) into a single integrated product. This consolidation simplifies the overall system by eliminating separate sensor installation and calibration procedures, reducing manufacturing complexity despite adding functional capability.
3Productivity
If brief changes are delayed, then caregiver workload is reduced, but patient comfort deteriorates and infection risk increases
Solution Approach 1:
The patent enables preliminary action by detecting void events in real-time and alerting caregivers immediately, allowing them to change briefs proactively before discomfort or infection risk increases. This proactive approach lets caregivers prioritize and schedule changes efficiently based on actual need rather than reacting to patient distress or following rigid schedules.
Solution Approach 2:
The real-time wetness monitoring provides continuous feedback to caregivers about which patients need attention, enabling them to optimize their workflow by responding only when necessary. This feedback-driven approach maintains high patient care standards while improving caregiver efficiency by eliminating unnecessary changes and prioritizing urgent cases.
