Flexible Maternity Belt with Surrounding Speaker Array
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for transmitting music and auditory stimuli to in-utero infants do not adapt to the changing shape of a pregnant woman's abdomen and lack the ability to limit sound frequencies to safe levels for the fetus, nor can they be easily modified for postnatal use.
Innovation Solution
A musical maternity belt with a flexible carrier, array of speakers, and amplifier that conforms to the abdomen, limits sound frequencies suitable for the fetus, and has a modular design for postnatal adaptation, allowing components to be removed or added for use with various infant accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing devices use fixed speaker positions on a rigid band, then the device structure is simple, but the device cannot adapt to the changing shape of a pregnant woman's abdomen
Solution Approach 1:
The band is designed as a flexible, dynamic structure that can adapt its shape to accommodate the changing contours of the pregnant woman's abdomen. The flexibility allows the device to transform from a rigid fixed structure to a dynamic adaptive form that conforms to the evolving abdominal shape throughout pregnancy.
Solution Approach 2:
The carrier band utilizes flexible materials and thin-film construction to enable conformability to the curved surface of the abdomen. This flexible shell approach allows the device to wrap around and adapt to the changing geometric form of the pregnant abdomen without requiring complex mechanical adjustment mechanisms.
2Object-affected harmful factors
If existing devices transmit full-range audio frequencies, then the audio quality is high, but harmful sound frequencies may damage the in-utero infant
Solution Approach 1:
The audio frequency spectrum is differentiated into local quality zones, with specific frequency ranges filtered or attenuated to remove harmful components while preserving beneficial frequencies. This selective frequency modification applies different quality characteristics to different parts of the audio spectrum, ensuring fetal safety while maintaining audio transmission reliability.
Solution Approach 2:
The device converts potentially harmful full-range audio frequencies into beneficial restricted-frequency audio by filtering out dangerous high frequencies and amplifying appropriate lower frequencies that are safe for fetal exposure. This transformation turns the harmful characteristic of full-range audio into a beneficial safe audio transmission system.
3Adaptability or versatility
If the device is designed specifically for prenatal use, then it provides optimal fetal stimulation, but it cannot be used after birth extending its useful life
Solution Approach 1:
The device is designed with universal applicability for both prenatal and postnatal use. The carrier band and speaker system can serve dual functions: providing fetal stimulation during pregnancy and continuing to provide auditory stimulation after birth. This multi-functionality extends the product lifecycle and eliminates the need for separate prenatal and postnatal devices.
Solution Approach 2:
The device is divided into modular segments including the carrier band, speaker array, and control electronics that can be independently configured or removed. This segmentation allows the core components to be retained and reused for postnatal applications while enabling easy modification of the device configuration for different usage phases.
4Productivity
If speakers are positioned to directly face the infant, then sound transmission efficiency is high, but the device does not conform to the curved shape of the abdomen
Solution Approach 1:
The speaker array is arranged in a three-dimensional configuration that follows the curved surface of the abdomen rather than a flat planar arrangement. This spatial distribution of speakers across multiple dimensions on the curved surface maintains optimal acoustic transmission paths to the fetus while conforming to the abdominal geometry.
Solution Approach 2:
The speaker positions and orientations are designed to follow the curved, spheroidal contour of the pregnant abdomen. This curvature-based arrangement ensures that speakers maintain appropriate positioning relative to the fetus throughout the curved surface area, preserving sound transmission efficiency while adapting to the abdominal shape.

Function Achieved in This Case
The musical maternity belt provides a comfortable and effective means of transmitting music and sounds to in-utero infants while accommodating the changing abdomen and can be easily converted for postnatal use, extending its functionality and usability.
Implementation Method 1
an amplifier operatively associated with the array of speakers and able to limit the frequencies and tonal qualities of the sounds emitted from the speakers
Implementation Method 2
an array of speakers disposed on said upper and lower arms; the speakers substantially surround the in-utero infant with the sounds emitted from said speakers
Data Source
AI summary
Presented herein is a system for transmitting sounds to an in-utero infant, that is worn by a pregnant woman, said system comprising a flexible carrier with two arms and adapted to accommodate the continuously changing shape of the abdomen of a pregnant woman; an array of speakers disposed on the arms of the carrier and substantially surrounding the in-utero infant with the sounds emitted from said speakers; an amplifier operatively associated with the array of speakers that enables tailoring the frequencies and tonal qualities of the sounds emitted from the array of speakers to levels suitable for an in-utero infant; and an audio device, operatively connected to the array of speakers and the amplifier, that provides a source from which sounds are played back.
