Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining fetal position and size during pregnancy, such as Leopold's Maneuvers and ultrasonic imaging, are not suitable for home use and require professional training or equipment, limiting untrained individuals' ability to monitor fetal development and interact with their unborn baby.
Innovation Solution
A fetal position monitoring system using a force and deformation sensor arrangement, combined with a data analysis processor and output device, allows untrained users to determine fetal position, size, and movement without medical expertise, utilizing a glove or abdominal belt to apply pressure and interpret resistance information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If Leopold's Maneuvers or ultrasonic imaging are used to determine fetal position and size, then measurement precision is improved, but device complexity and ease of operation worsen due to requiring professional training and equipment
Solution Approach 1:
The patent replaces manual mechanical examination (Leopold's Maneuvers) with an automated sensor system that uses force sensors, deformation sensors, and capacitive touch sensors to objectively measure fetal position and size, eliminating the need for professional manual examination skills while maintaining measurement accuracy
Solution Approach 2:
The monitoring device integrates multiple sensing capabilities (force sensing, deformation sensing, capacitive touch) into a single universal system that can perform various fetal monitoring functions including position determination, size estimation, and movement detection, making it suitable for both clinical and home use
2Measurement precision
If ultrasonic imaging systems are used to examine fetal development, then measurement precision is improved, but device complexity and cost worsen due to requiring expensive diagnostic equipment
Solution Approach 1:
The patent employs inexpensive sensor elements (force sensors, deformation sensors, capacitive touch sensors) that can be integrated into affordable monitoring devices, replacing expensive ultrasonic imaging equipment while providing sufficient accuracy for fetal position and size monitoring in home settings
Solution Approach 2:
The system substitutes complex ultrasonic imaging machinery with simpler mechanical sensing mechanisms that directly measure fetal characteristics through the maternal abdomen, dramatically reducing device complexity and cost while maintaining useful measurement precision
3Ease of operation
If manual examination procedures are used by untrained persons, then ease of operation is improved, but measurement precision worsens due to lack of professional training
Solution Approach 1:
The monitoring system enables untrained users to perform accurate fetal monitoring themselves through automated sensors and clear visual feedback displays, eliminating the need for professional training while maintaining measurement precision through objective sensor data rather than subjective manual examination
Solution Approach 2:
The system provides real-time visual feedback through displays that show fetal position, size, and movement information, guiding untrained users on how to properly use the device and interpret results, thereby ensuring accurate measurements without requiring professional expertise

AI summary
The invention provides a fetal position monitoring system, comprising an abdominal belt or a glove comprising a force and/or deformation sensor arrangement for obtaining resistance information of a plurality of local areas of the abdomen in response to an applied pressure. A data analysis processor interprets the resistance information to derive a fetal position and/or fetal size and optionally also fetal movement and an output is provided giving a representation of the fetal position and/or fetal size and optionally also fetal movement. This system provides a way of generating an output of the fetal position or size which requires minimum medical knowledge of the user, and it may be used at home.
