Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional techniques (envelopment, immersion into cushions, offloading pressure, periodic turning/repositioning) are used to control pressure ulcers, then pressure ulcer prevention is achieved, but healthcare costs increase and quality of life decreases
Solution Approach 1:
The system performs preliminary detection of pressure and moisture conditions before pressure ulcers develop. Sensors continuously monitor interface conditions and predict ulcer risk, enabling preventive action before the actual harm occurs, rather than reacting after ulcers form
Solution Approach 2:
The system implements continuous feedback through sensors that monitor pressure and moisture levels at the individual-surface interface. This feedback loop provides real-time information about developing risk conditions, allowing dynamic adjustment of prevention strategies based on actual measured parameters
2Reliability
If conventional techniques (envelopment, immersion into cushions, offloading pressure, periodic turning/repositioning) are used to control pressure ulcers, then pressure ulcer prevention is achieved, but healthcare costs increase
Solution Approach 1:
The system enables early detection and prediction of pressure ulcer risk before actual ulcers develop. By identifying high-risk conditions through sensor data and applying predictive algorithms, the system allows for targeted, timely interventions that prevent costly ulcer treatment
Solution Approach 2:
The system empowers individuals and caregivers with real-time information about pressure and moisture conditions. Through alerts and notifications, the system enables self-monitoring and self-management of pressure ulcer risk, reducing the need for expensive professional healthcare interventions
3Reliability
If conventional techniques (envelopment, immersion into cushions, offloading pressure, periodic turning/repositioning) are used to control pressure ulcers, then pressure ulcer prevention is achieved, but quality of life decreases
Solution Approach 1:
The system allows individuals to monitor their own pressure and moisture conditions through wearable or integrated sensors. Users receive personalized feedback and alerts about their risk levels, enabling them to take control of their own prevention without requiring constant caregiver intervention or restrictive positioning
Solution Approach 2:
The system replaces static, periodic intervention schedules with dynamic, real-time monitoring and response. Pressure and moisture conditions are continuously assessed, and interventions are triggered only when actual risk thresholds are exceeded, allowing greater freedom of movement and more natural behavior
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
The system effectively predicts and prevents pressure ulcers by alerting interventions when threshold values are reached, reducing healthcare costs and enhancing quality of care.
Implementation Method 1
The pressure sensing component can include two high conductive fabrics configured to make contact through a low conductive fabric forming a pressure sensor
Implementation Method 2
The moisture sensing component can include two conductive fabrics placed adjacent or next to each other forming a moisture sensor, the two conductive fabrics optionally separated by an insulating fabric, wherein moisture closes the circuit in the moisture sensor when moisture passes or percolates from one of the conductive fabrics to the other of the conductive fabrics

AI summary
Disclosed are various embodiments for a pressure ulcer monitoring and prevention system. A fabric-based sensing component with a pressure sensing component and/or a moisture sensing component, and interconnections to route signals from one or more of the sensing components to a computing device is provided. An application causes the computing device to determine that an individual is at risk for developing a pressure ulcer. In response to determining that the individual is at risk for developing a pressure ulcer, the application can alert a manual intervention or trigger an automated intervention between the individual and the surface.
