Multi-Channel Strain Bladder Sensor for Anisotropic Volume Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bladder monitoring systems struggle to accurately track anisotropic volume changes of the bladder, which is crucial for determining urination timing and ensuring complete bladder emptying. Current sensors often have limitations in reproducibility, information accuracy, and are not capable of securing data in all directions of expansion.
Innovation Solution
A multi-channel strain bladder sensor verification method is introduced, which involves controlling the expansion and contraction of a measurement object simulating a bladder, obtaining sensing values from each channel of the sensor, and analyzing these values to track volume changes and expansion directions. This method allows for the verification of the bladder sensor in a closed-loop system environment, ensuring accuracy and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-channel sensor is used to monitor bladder volume, then the device complexity is reduced, but the measurement precision and ability to track anisotropic volume changes deteriorate
Solution Approach 1:
The bladder monitoring function is segmented into multiple independent sensing channels, each capturing volume changes in specific directions. This segmentation allows the system to comprehensively track anisotropic volume changes while maintaining manageable device complexity through modular architecture.
Solution Approach 2:
The invention transitions from single-dimensional volume monitoring to multi-dimensional tracking by adding spatial dimensions to the sensing capability. Multiple channels are positioned to detect expansion in different directions, enabling comprehensive three-dimensional volume change assessment.
2Measurement precision
If multiple sensors are placed inside the bladder to measure internal pressure, then the measurement precision improves, but the reliability deteriorates due to severe chemical and physical environment
Solution Approach 1:
The invention introduces an intermediary approach by placing sensors on the external surface of the bladder rather than inside it. The sensors measure volume changes of the bladder wall itself, which correlates to internal pressure changes without exposing the sensors to the harsh chemical and physical environment of bladder contents.
Solution Approach 2:
Instead of directly measuring internal pressure with sensors exposed to bladder contents, the system copies the volume change information by measuring the external dimensions and shape changes of the bladder wall, providing equivalent diagnostic data without the reliability issues of internal sensor placement.
3Reliability
If conventional sensors are attached to the bladder wall to measure volume changes, then the reliability improves by avoiding internal environment, but the measurement precision deteriorates due to limited sensing directions
Solution Approach 1:
The monitoring function is segmented across multiple sensing channels positioned at different locations and orientations on the bladder wall. Each channel captures volume changes in its specific sensing direction, and the combined data provides comprehensive three-dimensional volume change information with high precision.
Solution Approach 2:
The multi-channel sensor system provides universal monitoring capability by simultaneously detecting volume changes in multiple directions. This multi-functional approach enables comprehensive bladder volume assessment regardless of the direction or pattern of expansion, enhancing both reliability and measurement precision.
