Infant Sleep Surface Insert With Alternating Air Chambers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infants sleeping face down are at risk of carbon dioxide re-breathing, which contributes to Sudden Infant Death Syndrome (SIDS), as existing recommendations for placing infants on their backs are not always followed due to discomfort and the tendency for infants to roll over or regurgitate, leading to concerns about choking.
Innovation Solution
A sleep surface insert system with a blower and actuator that alternates air flow between hollow spaces in the insert, providing oxygen and gently rocking the infant to prevent carbon dioxide buildup, while monitoring heart rate and respiration and controlling air temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If infants are placed on their backs for sleeping, then the risk of carbon dioxide re-breathing is reduced, but infants may experience discomfort and roll over to their preferred position
Solution Approach 1:
The mattress is divided into multiple independent air chambers that can be individually controlled. This segmentation allows different zones of the mattress to have different firmness and support characteristics, accommodating infants who prefer to sleep on their stomachs while still maintaining proper air flow to prevent carbon dioxide re-breathing.
Solution Approach 2:
The mattress incorporates dynamically adjustable air chambers that can change firmness and support in real-time. This dynamic adjustment allows the mattress to adapt to the infant's preferred sleeping position and movements, preventing discomfort and rolling over while maintaining safety.
2Ease of operation
If infants are placed on their stomachs for sleeping, then they maintain their preferred position, but they are at risk of carbon dioxide accumulation in the air pocket near their air passages
Solution Approach 1:
The mattress uses a pneumatic system with multiple air chambers that can be independently inflated and deflated. When an infant sleeps on their stomach, the system adjusts the air chambers to maintain proper ventilation and prevent carbon dioxide accumulation in the area near the infant's air passages, while still supporting the preferred sleeping position.
Solution Approach 2:
The system changes physical parameters such as air pressure and chamber volume in real-time based on the infant's position and breathing patterns. This allows the mattress to optimize air flow and prevent carbon dioxide buildup while accommodating the infant's preferred stomach sleeping position.
3Object-affected harmful factors
If a firm mattress is used to prevent carbon dioxide buildup, then air flow is improved, but the mattress may be too hard for infant comfort
Solution Approach 1:
The mattress is segmented into multiple air chambers with different firmness levels. This allows the surface in contact with the infant to remain soft and comfortable, while underlying chambers maintain proper air flow and prevent carbon dioxide buildup. Each chamber can be independently adjusted to achieve the desired balance between comfort and ventilation.
Solution Approach 2:
Different regions of the mattress have different firmness and air flow characteristics tailored to local needs. The area near the infant's head and air passages has optimized air flow to prevent carbon dioxide buildup, while other areas provide enhanced comfort and support.
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 system effectively reduces the risk of SIDS by ensuring adequate oxygenation and preventing carbon dioxide accumulation, while also monitoring vital signs and adjusting air temperature for comfort.
Implementation Method 1
The blower is configured to provide air flow into the first hollow space and the second hollow space defined in the insert, the air flow configured to flow into the insert and out of at least one of the first multiple pores and the second multiple pores
Implementation Method 2
The actuator is configured to alternate inflation of the insert between the first hollow space and the second hollow space defined therein

AI summary
A sleep surface insert system and method for positioning under, for example, an infant on a sleep surface. The sleep surface insert system includes an insert and a blower system. The insert includes a top liner and a bottom liner. The top liner and bottom liner define first and a second hollow spaces therebetween. Further, the top liner includes first and second pores such that the first pores extend through the top liner from the first hollow space and the second pores extend through the top liner from the second hollow space. In addition, the blower system is configured to provide air flow into the first and second hollow spaces defined in the insert such that the air flow is configured to flow into the insert and out of at least one of the first pores and the second pores.
