Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pressure redistribution systems are ineffective in dynamically adjusting to real-time pressure changes, leading to issues like pressure ulcers, stress fractures, and foot problems, as they are mostly passive and lack the ability to collect and respond to data for precise redistribution of forces.
Innovation Solution
An active multicompartmental pressure redistribution system using interconnected fluid-containing vessels with sensors and microcontrollers that adjust pressure in real time based on data synthesis and biomechanical principles, allowing fluid to redistribute from high to low pressure areas through dynamic flow regulators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If passive pressure redistribution materials (springs, rubber, foam, polymers) are used, then pressure redistribution is achieved, but the system cannot dynamically adjust to real-time pressure changes and eventually deforms losing efficacy
Solution Approach 1:
The patent transforms passive pressure redistribution materials into an active dynamic system by incorporating interconnected fluid-filled vessels with controllable flow regulators. The system dynamically adjusts pressure distribution in real-time based on sensor feedback, allowing adaptation to changing body positions and pressure patterns while maintaining long-term effectiveness without material deformation.
Solution Approach 2:
The system incorporates pressure sensors that continuously monitor pressure distribution and feed this data to a control algorithm. Based on this feedback, the system automatically adjusts flow regulator positions to redistribute fluid and equalize pressure, creating a closed-loop control system that maintains optimal pressure distribution adaptively.
2Object-affected harmful factors
If cushioning materials are used to decrease pressure, then pressure reduction is achieved, but the foot is locked in certain positions limiting range of motion and force distribution
Solution Approach 1:
The system replaces static cushioning materials with dynamic fluid-filled vessels that can change their pressure characteristics in real-time. As the foot moves or changes position, the system detects these changes and adjusts fluid distribution accordingly, maintaining pressure relief while allowing full range of motion and natural foot mechanics.
Solution Approach 2:
The patent uses fluid-filled vessels with controllable flow regulators to create a pneumatic/hydraulic pressure redistribution system. This allows pressure to be dynamically adjusted through fluid movement between vessels, providing pressure relief without the mechanical constraints of solid cushioning materials, thereby preserving natural foot movement and force distribution.
3Measurement precision
If sensors are used to collect pressure data, then pressure information is gathered, but the data is not used to make dynamic real-time changes in structure
Solution Approach 1:
The system creates a closed-loop control system where pressure sensors continuously monitor pressure distribution, the control algorithm processes this data in real-time, and flow regulators automatically adjust vessel pressures based on the analysis. This feedback mechanism transforms static data collection into dynamic real-time structural adjustment, equalizing pressure distribution adaptively.
Solution Approach 2:
The system incorporates an autonomous control algorithm that automatically analyzes sensor data and adjusts flow regulator positions without external intervention. The system serves itself by autonomously detecting pressure imbalances and redistributing fluid to correct them, enabling real-time adaptive pressure equalization based on collected pressure information.

Data Source
AI summary
An interconnected multicompartmental pressure redistribution system that is able to precisely identify contact pressure points and address excess pressure on the body by redistributing the pressure in real time. Sensors that are part of a matrix of fluid substance-filled interactive pixels communicate with a microcontroller that may also be in wireless communication with a smart device. The microcontroller controls the individual fluid flow regulators located between the interactive pixels. This causes specific flow regulators to open, allowing the fluid substance to flow from one interactive pixel to another, redistributing pressure, as needed.
