Ventilated Infant Head Support Pad With Adjustable Side Restraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infant head supports are often confining and uncomfortable due to insufficient ventilation, which can lead to suffocation and discomfort, and lack adequate support to prevent sudden head movements.
Innovation Solution
A ventilated infant support system featuring a padded base member with spaced openings and a deformable head support rail with adjustable side restraints, providing both lateral head movement prevention and flexible ventilation, suitable for use in various settings like car seats and strollers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional non-porous padding is used to provide firm support, then structural support is improved, but ventilation is worsened leading to suffocation risk
Solution Approach 1:
The patent employs porous foam material for the head support rail and base layer, which provides both structural support and ventilation. The porous structure allows air circulation while maintaining the firmness needed to prevent head collapse, thereby eliminating suffocation risk while preserving support strength.
Solution Approach 2:
The invention uses a composite structure combining porous foam material with a fabric cover layer. The foam provides structural support and ventilation channels, while the fabric cover maintains a soft, comfortable surface. This composite approach resolves the contradiction between firm support and breathable comfort.
2Ease of operation
If deformable head support material is used to provide comfort, then comfort is improved, but head support stability is worsened
Solution Approach 1:
The patent specifies that the foam material shall have a density of at least 0.03 grams per cubic centimeter and an ILD (Indentation Load Deflection) of at least 10 pounds. These parameter specifications ensure the foam is soft enough for infant comfort yet firm enough to maintain head support stability and prevent collapse.
Solution Approach 2:
The head support rail is designed with specific local properties - the foam material is positioned and configured to provide targeted support at critical areas while remaining comfortable. The rail's geometry and material distribution create localized support zones that maintain stability without compromising overall comfort.
3Reliability
If fixed head support structure is used to prevent lateral movement, then safety is improved, but adaptability is worsened
Solution Approach 1:
The patent incorporates adjustable side restraints with fasteners that can be moved to different positions. This dynamic adjustment capability allows the head support structure to adapt to different infant sizes and positions while maintaining the safety function of preventing lateral head movement. The restraints can be repositioned or removed as needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures a comfortable, ventilated, and secure support for infants, preventing suffocation and extreme discomfort while allowing for adjustable positioning to accommodate different surfaces and safety harnesses.
Implementation Method 1
The head support means performs the dual functions of preventing lateral movement of an infant's head while providing a flexible, ventilated support
Implementation Method 2
porous foam material having a density of at least 0.03 grams per cubic centimeter and an ILD (Indentation Load Deflection) of at least 10 pounds

AI summary
An infant support member, particularly for use with babies or smaller infants includes a padded base layer provided with spaced openings, a porous cover with smaller openings, and a head support member at one end of the base member for supporting and protecting an infant's head and neck, the head support member also including spaced openings and a ventilated cover for additional ventilation around the head portion, and releasable fasteners enable adjustment of the sides of the head support.
