Solution Overview

Problem

Preterm newborns in NICUs face challenges due to excessive noise levels and delicate skin, which existing noise-reducing measures like foam earcups and respiratory support devices fail to adequately address, leading to potential skin damage and suboptimal brain development.

Innovation Solution

A flexible medical headgear with a frequency-dependent auditory filter earcup and a non-stretch central portion with a friction pad, designed to provide sound attenuation similar to the in-utero environment, while offering a stable and gentle attachment method for respiratory support tubes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If foam earcups with hydrogel adhesive are used to reduce noise, then sound attenuation is provided, but the adhesive bond is either too weak (if lightly positioned to prevent skin damage) or too strong (requiring extreme care during removal), leading to skin damage

Engineering Contradiction:

Improvenoise exposureVSAvoidattachment and removal safety

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent changes the bonding mechanism from chemical adhesive bonding to mechanical friction bonding. The friction pad uses high-coefficient friction material that bonds through pressure and friction alone, eliminating the need for hydrogel adhesive. This allows the device to be attached and removed without skin damage while maintaining the acoustic seal for noise reduction.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces the chemical bonding system (hydrogel adhesive) with a mechanical bonding system (friction-based attachment). The friction pad creates a secure bond through friction and pressure, which can be easily applied and removed without causing skin damage, thus substituting the problematic chemical adhesive system with a safer mechanical alternative.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If conventional respiratory support tube attachment devices are used, then respiratory support is provided, but the devices are not suited for delicate preterm newborn skin and nasal septum, requiring extreme care during removal to avoid injury

Engineering Contradiction:

Improverespiratory support stabilityVSAvoidattachment and removal safety

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent integrates multiple functions into a single device. The friction pad serves both as an acoustic seal for noise reduction and as an attachment mechanism for respiratory support tubes. This multi-functional design eliminates the need for separate attachment devices that are harmful to preterm newborns, providing both noise protection and secure tube attachment through the same gentle friction-based mechanism.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the noise reduction function and the respiratory support attachment function into a single integrated system. The friction pad that creates the acoustic seal also serves as the attachment point for respiratory tubes, merging two previously separate functions into one unified device that is safe for delicate preterm newborn tissue.

Inventive Principle:

Principle #5Merging (Combining)

3Object-affected harmful factors

If foam earcups are used to reduce environmental noise, then some sound attenuation is provided, but the filtered sound profile does not correspond to the normal in-utero acoustic environment, limiting effectiveness

Engineering Contradiction:

Improveenvironmental noiseVSAvoidacoustic filtering accuracy

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent modifies the acoustic filtering characteristics by changing the material properties of the friction pad. The friction pad material is selected to provide frequency-dependent sound attenuation that replicates the in-utero acoustic environment, allowing low frequencies to pass while attenuating high frequencies, thus accurately reproducing the natural acoustic profile experienced by the fetus in the womb.

Principle #35Parameter changes

AI summary

A flexible band for a medical headgear comprises an inner surface, an opposite outer surface, and a non-stretch central portion having a friction pad disposed on the inner surface. The friction pad is formed from a grip or tacky material and is disposed at least partially between the inner surface and the outer surface of the non-stretch central portion in a solidified state of the friction pad.
