Infant Feeding Teat Aperture Positioning for Unobstructed Fluid Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing teat designs face blockage issues due to the positioning of apertures, which can be obstructed by the infant's tongue or palate during fluid intake, hindering fluid flow.
Innovation Solution
The teat features an aperture positioned in a central front area of the mouthpiece, with a design that creates a space between the mouthpiece and inner core for an unobstructed fluid flow path, including adaptations such as a recessed fluid pocket guiding face and a channel in the inner core to ensure fluid reaches the aperture without obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the aperture is positioned in the mouthpiece, then fluid can flow out of the teat, but the aperture can be blocked by the infant's tongue or palate during fluid intake
Solution Approach 1:
The teat is divided into functional zones: the aperture is positioned in the central front area for fluid ejection, while the inner core with its fluid pocket guiding face creates a protected fluid pathway. This segmentation separates the fluid intake function from the fluid ejection function, allowing the aperture to remain accessible while the fluid flow path is protected from blockage by the infant's tongue or palate.
Solution Approach 2:
The inner core acts as an intermediary structure between the fluid source and the aperture. Its fluid pocket guiding face with extended length creates a protected channel that guides fluid to the aperture, preventing direct contact between the infant's tongue/palate and the fluid flow path, thus preventing blockage while maintaining fluid ejection functionality.
2Reliability
If the inner core is disposed within the mouthpiece, then a fluid duct is defined for peristaltic action, but space is reduced for unobstructed fluid flow to the aperture
Solution Approach 1:
The inner core's exterior surface features a fluid pocket guiding face with extended length in specific locations, creating localized fluid pathways. This local quality enhancement ensures that fluid has a dedicated, protected path from the fluid source to the aperture, maintaining sufficient flow space in critical areas while allowing the inner core to occupy space in other areas for structural support and peristaltic action.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design prevents blockage and ensures continuous, unobstructed fluid flow, enhancing the reliability and functionality of the teat for peristaltic fluid intake, mimicking natural breast-feeding action and reducing nipple confusion between bottle and breast feeding.
Implementation Method 1
the infant to perform a peristaltic fluid intake action during which the mouthpiece is deformed and a fluid is forced along the fluid duct
Implementation Method 2
a deformable mouthpiece for an infant to suck on during a fluid intake action

AI summary
A teat (1) for use with a container for containing a fluid comprises a deformable mouthpiece (13) for an infant to suck on, and an inner core (20) disposed within the mouthpiece (13). The mouthpiece (13) has at least one aperture (12) therein for allowing a fluid to flow out of the teat (1). A fluid duct (30) between the mouthpiece (13) and the inner core (20) is defined at the position of a fluid pocket guiding face (23) of the inner core (20) whereby the infant is allowed to perform a peristaltic fluid intake action. The at least one aperture (12) is arranged in a central front area (15) of the mouthpiece (13), while the mouthpiece (13) and the inner core (20) are designed to leave space between them for a fluid flow path from the fluid pocket guiding face (23) to the at least one aperture (12).
