One-Piece Nipple Assembly with Texture Gradient for Infant Latching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baby bottles are difficult for infants to latch onto due to their smooth surface, which does not simulate a human breast, and are challenging for caregivers to use and clean due to their two-piece nipple design and slippery shape.
Innovation Solution
A feeding bottle with a one-piece nipple assembly that includes a rigid ring substrate and a pliable dome overmold, featuring textured surfaces and an internal flow assist mechanism, along with a detachable non-slip bottom and angled neck for improved ergonomics and fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a smooth surface nipple is used, then the bottle is easy to manufacture and clean, but the infant cannot latch onto it properly
Solution Approach 1:
The nipple assembly incorporates different surface qualities in different regions: the dome overmold has a smooth interior surface for easy cleaning while the exterior surface has a textured pattern to simulate human breast skin, enabling proper infant latching. This local differentiation of surface properties resolves the contradiction between ease of cleaning and effective latching.
2Reliability
If a two-piece nipple design is used, then the nipple can be securely attached to the container, but the assembly and cleaning process becomes complex
Solution Approach 1:
The invention merges the nipple head and dome overmold into a single integrated one-piece nipple assembly that attaches directly to the container. This eliminates the need for separate assembly steps and reduces cleaning complexity while maintaining secure attachment through the integrated design, resolving the contradiction between attachment reliability and operational simplicity.
3Ease of manufacture
If a cylindrical bottle with straight walls is used, then the bottle has simple geometry and is easy to manufacture, but it slips out of the caregiver's hand easily
Solution Approach 1:
The bottle incorporates an asymmetric base with a non-slip surface that provides enhanced grip stability for the caregiver. The base geometry is modified to create friction against the hand, while the main body retains a simple cylindrical shape for easy manufacturing. This localized geometric modification resolves the contradiction between manufacturing simplicity and hand grip stability.
4Weight of moving object
If conventional plastic material is used, then the bottle is lightweight and easy to clean, but it slides over the counter or tabletop
Solution Approach 1:
The bottle base is modified with a non-slip surface treatment that provides high friction contact with countertops, while the rest of the bottle body maintains its lightweight plastic composition. This localized surface modification allows the bottle to remain stable on surfaces without increasing overall weight, resolving the contradiction between light weight and counter stability.
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 design encourages proper infant latching, simplifies bottle preparation and cleaning, and provides a stable, non-slip surface for caregivers, enhancing the feeding experience for both infants and caregivers.
Implementation Method 1
The nipple assembly may also include a nipple head and a dome overmold, which are both pliable. The dome overmold encompasses and is bonded to the ring substrate to create the one-piece nipple assembly.
Implementation Method 2
An internal flow assist mechanism may be incorporated into an inside surface of the nipple head and the dome overmold. This mechanism is configured to allow fluid to flow through the nipple head when opposing walls of the nipple head are compressed to abut one another, such as when an infant bites on the nipple head.
Implementation Method 3
The nipple assembly may also include a nipple head and a dome overmold, which are both pliable and have at least one texture.
Implementation Method 4
The detachable bottom may be a non-slip material and has a coupling ridge for coupling to coupling channel of the container.
