Solution Overview

Problem

Turbulence in the flow of liquid from feeding teats can introduce air bubbles, causing discomfort and colic in infants, and the suction required to draw liquid can be excessive, leading to frustration and air intake.

Innovation Solution

A teat design featuring an anatomical nipple with intersecting reverse curves to promote laminar flow and a pressure relief valve system that keeps air away from the feeding zone, reducing turbulence and the need for excessive suction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If typical teat design is used, then liquid can be delivered to infant, but turbulence introduces air bubbles causing colic

Engineering Contradiction:
Improveair bubble incorporationVSAvoidfeeding comfort
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The teat incorporates curved flow channels and a rounded nipple geometry that guide liquid flow smoothly from the bottle through the teat to the infant. The curved pathways eliminate sharp angles and transitions that would create turbulence, thereby preventing air bubble incorporation while maintaining easy operation and feeding comfort.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Productivity

If higher suction is required to draw liquid from teat, then liquid flow can be controlled, but infant takes in additional air by breaking latch

Engineering Contradiction:
Improveliquid flow controlVSAvoidair intake
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The teat design modifies the flow parameters by creating a pressure gradient through its internal geometry. The gradual narrowing of the flow channel and the positioning of the liquid reservoir create optimal flow conditions that reduce the suction pressure required, preventing latch breaking and air intake while maintaining controlled liquid delivery to the infant.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If valves are integrated into teat to channel air into bottle, then vacuum can be prevented, but teat complexity and expense increase

Engineering Contradiction:
Improvevacuum preventionVSAvoidteat structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent removes the complex integrated valve mechanism from the teat and replaces it with a simple atmospheric communication opening in the teat body. This extraction of the valve function achieves vacuum prevention during feeding while dramatically simplifying the teat structure, reducing manufacturing complexity and cost.

Inventive Principle:
Principle #2Taking out (Extraction)

4Stability of the object's composition

If liquid contents settle or are pushed away from solution, then flow pattern changes, but feeding consistency is compromised

Engineering Contradiction:
Improveliquid content distributionVSAvoidfeeding consistency
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The teat design ensures continuous, smooth liquid flow through its optimized internal geometry. The curved channels and gradual transitions maintain constant flow velocity and direction, preventing the liquid contents from settling or separating from the solution. This continuous flow action delivers consistent nutrition to the infant throughout the feeding process.

Inventive Principle:
Principle #20Continuity of useful action

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 design reduces air bubble incorporation, minimizes the energy required for feeding, and prevents the settling of liquid contents, enhancing feeding comfort and efficiency.

Implementation Method 1

defining an interior profile shaped by intersecting reverse curves that generally decrease the interior diameter of the nipple portion toward the orifice, so as to channel fluid flow into the orifice

Methodology Applied
Scientific EffectLaminar flow: Laminar Flow

Implementation Method 2

reduce turbulent delivery of milk, formula or other feeding liquids to improve consistency. It can reduce turbulence so as to reduce cavitation, or the incorporation of air-bubbles

Methodology Applied
Scientific EffectTurbulence reduction: Turbulence

Implementation Method 3

a pressure relief valve constructed and arranged to admit air into the interior of at least one of the teat and the bottle

Methodology Applied
Scientific EffectPressure equalization: Pressure Gradient

Implementation Method 4

The vent(s) in the teat keep air away from the nipple and keep fluid moving smoothly. These valves can be formed in part by the teat and in part by the regions of the bottle that are contacted by these parts of the teat

Methodology Applied
Scientific EffectVacuum prevention: Vacuum

AI summary

A feeding teat (40) constructed and arranged to be used on a bottle (52) that holds and dispenses a liquid to be fed to an infant or child. The teat (40) has a nipple portion (70) with an orifice (71) at a terminal end, and defines an interior profile shaped by intersecting reverse curves (75, 76) that generally decrease the interior diameter of the nipple portion (70) toward the orifice (71), so as to channel fluid flow into the orifice (112). There is a flange portion (66) constructed and arranged to be releasably coupled to the bottle (52) such that the liquid can flow from the bottle (52) into the teat (40), and a convexly shaped intermediate portion (80) integrally connecting the nipple portion (70) to the flange portion (66). A pressure relief valve (60) built into the teat (40) is constructed and arranged to admit air into the interior of at least one of the teat (40) and the bottle (52).
