Solution Overview
Problem
Medical devices with inflatable members, such as those used to address continence issues, face challenges in efficiently managing pressure to conserve battery power and maintain system efficiency, as existing systems lack effective calibration to prevent overinflation or deflation.
Innovation Solution
A bodily implant with an inflatable member, sensor, and calibration module that detects fluidic pressure and determines when pressure is applied to the body, using a pump system to manage inflation and deflation, and a smoothing module to process pressure data for accurate calibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the inflatable member is continuously inflated to maintain pressure on the body portion, then the therapeutic effect is maintained, but battery power is consumed faster
Solution Approach 1:
The system uses periodic deflation and reinflation cycles instead of continuous inflation. The calibration module determines when pressure is no longer needed and triggers deflation, then reinflates when needed again. This periodic operation maintains therapeutic effectiveness while allowing battery conservation during deflation periods.
Solution Approach 2:
The sensor continuously monitors pressure within the inflatable member and feeds this data to the calibration module. The calibration module processes this feedback to determine when the inflatable member is no longer applying pressure to the body portion, enabling intelligent control of inflation/deflation cycles to optimize both therapeutic effect and power consumption.
2Reliability
If the inflatable member is overinflated to ensure adequate pressure, then pressure application is guaranteed, but system efficiency decreases and battery power is wasted
Solution Approach 1:
The sensor provides real-time pressure feedback to the calibration module, which processes the data to determine the exact moment when adequate pressure is achieved and when pressure is no longer needed. This feedback mechanism prevents both overinflation and underinflation, optimizing system efficiency.
Solution Approach 2:
Instead of maintaining continuous full inflation, the system applies pressure only when and for as long as it is therapeutically needed. The calibration module determines the precise timing of pressure application, avoiding excessive inflation and thereby improving system efficiency while ensuring adequate pressure when required.
3Use of energy by moving object
If the inflatable member is deflated to conserve battery power, then energy efficiency improves, but pressure support to the body portion is reduced
Solution Approach 1:
The sensor continuously monitors pressure and provides feedback to the calibration module, which determines the optimal timing for deflation and reinflation. This ensures that pressure support is maintained during periods when it is therapeutically necessary while allowing deflation during periods when support is no longer needed, thus conserving battery power without compromising reliability.
Solution Approach 2:
The system employs periodic deflation and reinflation cycles based on calibration data. During deflation periods, battery power is conserved, while during reinflation periods, therapeutic pressure support is restored. This periodic action balances power conservation with reliable pressure support timing.
4Use of energy by moving object
If a calibration system is added to determine pressure application timing, then power efficiency improves, but device complexity increases
Solution Approach 1:
The calibration module serves multiple functions: it receives sensor data, processes pressure information, determines when pressure is applied, controls deflation timing, and triggers reinflation. By making this single module multi-functional, the system achieves power efficiency without proportionally increasing complexity.
Solution Approach 2:
The calibration module combines multiple control functions into a single integrated unit that coordinates the sensor, pump, and inflatable member control. This merging of functions reduces the overall system complexity compared to having separate dedicated components for each function, while still achieving the power efficiency benefits of intelligent pressure management.
