Radially Offset Nipple Latch With Variable Wall Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Nipples used for bottle-feeding often lead to suboptimal latching due to improper orientation, causing air intake and nipple confusion, which can result in discomfort and hinder breast-feeding abilities in infants.
Innovation Solution
A nipple design featuring a radially offset latch portion with a region of reduced wall thickness, enhancing the infant's ability to form a secure latch and mimic the natural feeding process by allowing a more realistic and comfortable sucking action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the nipple is designed with uniform wall thickness, then the manufacturing process is simple, but the latching security and natural feeding sensation are insufficient
Solution Approach 1:
The nipple incorporates a region of reduced wall thickness specifically in the latch portion where the infant's tongue contacts during feeding. This localized structural variation enhances the natural feeding sensation and improves latching security without complicating the overall manufacturing process, as it can be achieved through standard molding techniques with varied wall thickness specifications.
2Reliability
If the latch portion is positioned centrally, then the structure is symmetric and simple, but the infant's ability to form a secure latch and achieve stripping action is reduced
Solution Approach 1:
The latch portion is deliberately positioned radially offset from the central axis of the nipple, creating an asymmetric configuration. This asymmetry enables the infant's tongue to effectively engage the latch portion during feeding, facilitating proper stripping action and secure latch formation, while still maintaining manufacturing simplicity through conventional molding processes.
3Reliability
If the bottle is held in optimal orientation, then feeding resembles breast-feeding and reduces nipple confusion, but the bottle becomes difficult to hold stable and may extend away from the infant's mouth
Solution Approach 1:
The radially offset latch portion with reduced wall thickness enables the nipple to self-adjust and maintain optimal feeding characteristics regardless of bottle orientation. The structural design allows the latch portion to naturally engage the infant's tongue effectively, maintaining stripping action and reducing nipple confusion even when the bottle is held at various angles, thereby reducing the need for precise orientation control.
4Ease of operation
If the infant is reclined during feeding, then comfort is improved, but the bottle becomes more vertical and the infant must suckle with greater force against gravity
Solution Approach 1:
The region of reduced wall thickness in the latch portion compensates for the effects of gravity when the infant is reclined. This localized structural feature enhances the flexibility and responsiveness of the latch portion, allowing it to maintain effective engagement with the infant's tongue and facilitate easier extraction of contents even when the bottle is positioned more vertically due to infant reclining.

AI summary
A nipple or teat, particularly a nipple for attachment to a container. The nipple comprises a breast portion having a central region, and a latch portion extending from the breast portion, the latch portion comprising a teat portion and an areola portion. The latch portion is radially offset from the central region of the breast portion and includes an outer wall. The outer wall of the latch portion includes a first region having a first wall thickness and a second region having a second wall thickness, wherein the second wall thickness is less than the first wall thickness. A nipple assembly, feeding assembly and comforter assembly, each including the nipple or teat, are also disclosed.
