Deformable Feeding Bottle Separation Component for Flow Regulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing feeding bottle teat components allow milk flow to increase with high suction pressure, leading to the risk of overfeeding infants due to the time delay between stomach signals and brain response, as the flow rate is not efficiently regulated.
Innovation Solution
A separation component with a hole wall portion that reduces its cross-sectional area with increased pressure difference, maintaining a substantially constant flow rate by deforming in response to suction pressure, thereby reducing the dependency on suction pressure applied by the infant.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the hole cross-sectional area is kept constant, then the flow rate increases with suction pressure, but this leads to overfeeding risk due to inability to regulate flow rate
Solution Approach 1:
The hole wall portion is designed to be deformable, allowing the hole cross-sectional area to dynamically change in response to suction pressure. As suction pressure increases, the hole wall deforms to reduce the cross-sectional area, automatically regulating the flow rate to remain substantially constant and preventing overfeeding.
Solution Approach 2:
The invention changes the physical state of the hole wall portion from rigid to flexible, enabling it to change its geometric parameters (cross-sectional area) in response to pressure changes. This parameter change allows the system to maintain constant flow rate despite variations in suction pressure.
2Productivity
If the hole wall portion deforms to reduce cross-sectional area with increased pressure difference, then flow rate is maintained constant, but the hole stability may be affected
Solution Approach 1:
The hole wall portion is constructed as a flexible element that can deform under pressure. This flexible structure allows controlled changes in cross-sectional area while maintaining overall hole stability, enabling the system to regulate flow rate without compromising the structural integrity of the separation component.
3Shape
If the first dimension is significantly larger than the second dimension, then the hole shape becomes non-circular, but this reduces hole formation stability
Solution Approach 1:
The invention deliberately creates an asymmetric hole geometry where the first dimension is at most two times the second dimension. This controlled asymmetry optimizes the deformation characteristics of the hole wall portion, allowing sufficient flexibility for flow rate regulation while maintaining stable hole formation and preventing excessive distortion during deformation.
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 significantly reduces the risk of overfeeding by maintaining a constant flow rate regardless of suction pressure, ensuring a stable and controlled milk flow to the infant.
Implementation Method 1
the hole wall portion preferentially deforms or deflects in response to the applied pressure, wherein the geometry of the hole wall portion results in a reduction of the cross-sectional area of the hole due to the deformation or deflection
Implementation Method 2
when a pressure of the feeding space side is lower than a pressure of the container space side, a minimum cross-sectional area of the hole is reduced with increased pressure difference between feeding space and container space

AI summary
The present invention relates to a separation component (10) for a feeding bottle device (1) and a corresponding feeding bottle device (1). The separation component (10) provides a separation between a container space (2) of the baby bottle device (1) and a feeding space (3) for providing liquid to an infant, the separation component (10) comprising a hole wall portion (30) surrounding a hole (32) through the separation component (10) for allowing a passage of fluid from the container space (2) to the feeding space (3) therethrough, wherein the hole wall portion (30) is formed such that, when a pressure of the feeding space (3) side is lower than a pressure of the container space (2) side, a minimum cross-sectional area of the hole (32) is reduced with increased pressure difference between feeding space (3) and container space (2). A decreased risk of overfeeding an infant is achieved.
