Disposable Teat Unit Overmolding Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing teat units for baby bottles are designed for repeat use, making cleaning challenging, especially in hospitals or during travel, and do not adequately meet the needs of premature babies or those with sucking difficulties, as they are not suitable for single-use disposal and do not provide a natural sucking action.
Innovation Solution
A method for producing a disposable teat unit with a support body and securing part, where the teat is overmolded to cover recesses on the support body, forming a connection that is either rigid or allows short-distance movement, enabling a natural sucking action while being inexpensive to produce and easy to use, featuring a soft teat and rigid support for optimal mouth support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional teat units are designed for repeat use with separate components, then cleaning is required, but this makes them unsuitable for single-use disposal and increases complexity
Solution Approach 1:
The patent combines multiple separate components (teat, support body, and securing part) into a single integrated unit produced by overmolding. The teat material is overmolded directly onto the support body and securing part, creating an inseparable unified structure that eliminates cleaning requirements and enables single-use disposal while maintaining all necessary functions.
Solution Approach 2:
The patent implements a nested structure where the teat is overmolded over the support body which contains recesses, and the securing part is integrated within the same molded structure. The teat covers the recesses of the support body, creating a nested arrangement where smaller components are embedded within larger ones, achieving functional integration without separate assembly.
2Stability of the object's composition
If a rigid connection is used between support body and securing part, then structural stability is improved, but natural sucking action is reduced
Solution Approach 1:
The patent creates a dynamic connection between the support body and securing part through the overmolded teat material. While the overall structure remains stable, the teat allows for short-distance movement and deformation during sucking, providing the necessary flexibility for natural sucking action while maintaining structural integrity through the integrated molded design.
3Adaptability or versatility
If multiple separate components are used, then functionality is improved, but manufacturing cost and assembly complexity increase
Solution Approach 1:
The patent merges the teat, support body, and securing part into a single overmolded component, eliminating the need for separate manufacturing and assembly processes. This integration reduces manufacturing steps, lowers production costs, and simplifies the supply chain while maintaining all necessary functional capabilities through the unified design.
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 teat unit allows for a natural sucking action, is inexpensive to produce, and is ready for use without assembly, making it suitable for single-use disposal, particularly beneficial for premature babies and those with sucking difficulties.
Implementation Method 1
forming a teat by overmolding the teat over the support body and over the recesses of the support body so that the teat covers the recesses, and overmolding the teat over an upper edge of the securing part, thereby forming a connection between the securing part and the support body

AI summary
A method for making teat unit including providing a support body and a securing part, the support body including a plurality of recesses, forming a teat by overmolding the teat over the support body and over the recesses of the support body so that the teat covers the recesses, and overmolding the teat over an upper edge of the securing part, thereby forming a connection between the securing part and the support body which connects the securing part to the support body. In another method, the support body and the securing part are already one single piece and the teat is overmolded at least over the support body.
