Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional support surfaces fail to effectively control the spatial relationship between patients and the therapeutic surface, leading to the formation of pressure injuries in mobility-impaired individuals due to inadequate pressure distribution, which can result in ischemia, reperfusion injury, and prolonged recovery times.
Innovation Solution
A non-invasive pressure-mitigation apparatus with independently pressurized chambers configured in an anatomy-specific geometric pattern that actively orients the patient over a support surface, controlling pressure by inflating or deflating chambers to redistribute pressure and prevent prolonged vascular compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional support surfaces are used, then the device complexity is low, but the reliability of pressure mitigation is insufficient
Solution Approach 1:
The support surface is divided into multiple independently controllable chambers or zones that can be pressurized or deflated separately. This segmentation allows precise control of pressure distribution across different anatomical regions, improving pressure mitigation reliability while maintaining manageable system complexity through modular design
Solution Approach 2:
The support surface transitions from a static conventional design to a dynamic system with actively controlled chambers that can adjust pressure in real-time. This dynamic capability enables the system to adapt to changing patient needs and pressure patterns, significantly improving pressure mitigation effectiveness
Solution Approach 3:
The system incorporates pressure sensors and control mechanisms that monitor pressure distribution and automatically adjust chamber pressurization accordingly. This feedback loop ensures optimal pressure mitigation is maintained continuously, enhancing reliability through automated regulation
2Productivity
If conventional support surfaces are used, then the ease of operation is high, but the loss of time for healing is increased
Solution Approach 1:
The support surface employs periodic cycles of pressurization and deflation of different chambers, creating rhythmic pressure changes that promote blood flow and tissue healing. This periodic action accelerates recovery compared to static surfaces, reducing hospital stay duration while maintaining ease of operation through automated cycling
Solution Approach 2:
The system dynamically changes pressure parameters (magnitude, distribution, timing) to optimize healing conditions. By adjusting these parameters based on patient response and injury severity, the system accelerates healing speed and reduces overall treatment time
3Measurement precision
If conventional support surfaces are used, then the device complexity is low, but the measurement precision of pressure distribution is insufficient
Solution Approach 1:
The system replaces simple mechanical pressure distribution with an electronically controlled pneumatic or hydraulic system. This substitution enables precise measurement and control of pressure at multiple locations simultaneously, achieving high measurement precision while managing complexity through electronic control systems
Solution Approach 2:
Pressure sensors and control mechanisms act as intermediaries between the support surface and the patient. These intermediaries provide precise measurement of pressure distribution and enable fine-tuned adjustment, achieving accurate pressure control without directly complicating the patient-contact surface

AI summary
Introduced here are apparatuses and systems for mitigating contact pressures applied to a human body by the surface of an object, such as a chair, bed, or table. A pressure-mitigation apparatus can include a series of chambers whose pressure can be individually varied. When placed between a patient and a contact surface, the pressure-mitigation apparatus can vary the contact pressure on a specific anatomical region of the patient by controllably inflating and/or deflating one or more cell. Moreover, a pressure-mitigation system can be readily integrated into a conventional treatment regimen for a variety of different conditions.
