Smart Defecation Detection System for Nursing Homes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for monitoring and managing defecation events in individuals with limited mobility or in group settings, such as nursing homes, are inefficient, leading to unattended diapers and increased risk of secondary diseases, and require frequent tag registration and reattachment, which burdens caregivers.
Innovation Solution
A smart defecation detection device system that includes detachable sensors on wearable objects, a relay device for real-time data transmission, and a control server for comprehensive management and notification of defecation events, allowing for real-time monitoring and analysis of defecation patterns to optimize care and reduce unnecessary workload for caregivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tag for defecation/urination detection is attached to a diaper and registered with an RFID reader every time a diaper is replaced, then defecation detection capability is achieved, but the workload of managers who should manage a plurality of protected persons is increased
Solution Approach 1:
The system enables automatic detection and notification without requiring manual tag registration by managers. The defecation detection tag automatically communicates with the RFID reader when a diaper is worn, and the system automatically notifies caregivers, eliminating the need for manual registration operations.
Solution Approach 2:
The RFID reader is pre-configured with detection parameters and the system is prepared to automatically recognize and process defecation events. The infrastructure is set up in advance so that when a tagged diaper is worn, detection occurs immediately without requiring preliminary manual registration steps.
2Reliability
If a tag for defecation/urination detection is attached to an inner side of the diaper, then defecation detection is enabled, but the tag is difficult to reuse
Solution Approach 1:
The detection system is divided into separate components: the defecation detection tag and the RFID reader. The tag can be detached from the diaper after use and reused with subsequent diapers, while the RFID reader remains as a stationary reading device. This segmentation enables tag reuse while maintaining detection accuracy.
Solution Approach 2:
The RFID reader acts as an intermediary between the detection tag and the diaper. Instead of permanently attaching the tag to the diaper interior, the reader mediates the detection process by reading the tag when the diaper is worn, enabling tag reuse across multiple diapers.
3Loss of information
If guardians continuously monitor defecation by visiting protected persons, then defecation monitoring is achieved, but it is not only realistically difficult to continuously visit but also the work burden is very large for a small number of managers
Solution Approach 1:
The system provides automatic feedback when defecation occurs. The defecation detection tag detects the event and triggers an automatic notification to caregivers through the RFID system, eliminating the need for continuous manual monitoring while ensuring complete detection of defecation events.
Solution Approach 2:
The manual mechanical monitoring system (guardians physically visiting and checking) is replaced with an automated electronic detection system. The RFID-based defecation detection tag and reader system automatically performs monitoring functions that previously required continuous human intervention.

AI summary
Provided is a healthcare system including a smart defecation detection device. The healthcare system according to an embodiment of the present invention includes: a smart defecation detection device that is detachable to a wearable object of a protected person and detects defecation of the protected person, wherein the smart defecation detection device is provided as one of a plurality of smart defecation detection devices; a relay device that receives detection information in real time from the plurality of smart defecation detection devices; a control server that receives the detection information of the plurality of smart defecation detection devices in real time from the relay device, and comprehensively manages whether a defecation event has occurred and whether processing of the defecation event has been completed for each protected person, based on the detection information; and a reception device configured to receive notification information so that an assigned manager or ward/management station in charge of the protected person in whom the defecation event has occurred is allowed to be aware of the defecation event when it is determined that the defecation event has occurred based on the detection information of the smart defecation detection device.
