Sanitizable Neonatal Audio Shell for Safe Sound Exposure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current audio devices for neonatal care do not adequately address the need for developmentally appropriate audio stimulation for preterm and premature infants, as they often produce loud or prolonged sounds that can damage infant development, and fail to ensure sanitization to prevent infection.
Innovation Solution
A sanitizable audio device with a smooth, curved shell design that houses electronic components including a speaker, motion sensor, and microcomputer, which emits audio at predetermined volumes and durations, and can be sanitized to prevent infection, ensuring safe and developmentally appropriate sound exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If audio devices are used to stimulate infants, then developmental benefits are achieved, but loud or prolonged sounds may damage infant development
Solution Approach 1:
The device incorporates a microcomputer that precisely controls audio parameters including volume level (maintained at preset safe levels), duration (limited to preset time intervals), and timing (activated only upon detecting infant arousal). These parameter changes ensure audio stimulation remains beneficial without causing sound damage.
Solution Approach 2:
The motion sensor provides feedback about infant arousal state, which the microcomputer uses to control audio activation. This feedback mechanism ensures audio is only played when the infant is aroused and ready to receive stimulation, preventing prolonged or inappropriate sound exposure.
2Ease of operation
If articles come into contact with preterm and premature infants, then care is provided, but infection risk increases requiring sanitization
Solution Approach 1:
The audio device features a smooth shell with no crevices, seams, or protrusions that could harbor bacteria. This smooth surface design allows the entire device to be easily sanitized by wiping with appropriate solutions, eliminating infection risks while maintaining ease of use in infant care.
3Ease of operation
If the outer surface of the smooth shell comprises switch apertures, then switch accessibility is improved, but surface smoothness and sanitization capability may be compromised
Solution Approach 1:
The switch apertures are designed as curved, recessed openings in the smooth shell rather than sharp corners or protruding elements. This curved design maintains the overall smooth surface topology that prevents bacterial harboring, while still providing accessible switch actuation points for user operation.
Solution Approach 2:
The switches are nested within the smooth shell structure, with actuation surfaces that are flush with or recessed into the outer surface. This nesting approach allows switch functionality to be integrated without creating surface irregularities that would compromise sanitization capability.

AI summary
A sanitizable audio device for use in neonatal care and method of use are provided herein. The audio device comprises a smooth shell defining an outer surface and an inner surface. The outer surface forms a curved continuous smooth surface. The inner surface supports electronic elements. The shell defines one or more switch apertures, housing one or more actuatable electrical switches, in communication with the electronic elements. The method of use comprises generating on audio output including selecting content that is age appropriate for a particular infant, altering a sound emission of a recording of a care-giver of the particular infant, and programming a music player to emit the audio output below an age dependent volume, for an age dependent number of intervals per day and per week, for an age dependent duration.
