Solution Overview

Problem

Parents face challenges in finding the right teat shape and stiffness for their babies, leading to expensive and frustrating trial-and-error processes, as existing teats do not adequately mimic the natural sucking experience due to varied baby and mother breast shapes.

Innovation Solution

A teat unit with a manually operable adjustment mechanism that changes the shape and/or rigidity of the teat, allowing it to be adjusted to different appearances and stiffness levels, which can be set before or during use, and returns to a baseline configuration, enabling the same teat to be adapted to a baby's changing needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple differently shaped teats are provided to match different baby preferences, then the adaptability to baby needs is improved, but the device complexity and cost increase

Engineering Contradiction:
Improveadaptability to baby preferencesVSAvoidnumber of different teats
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The teat incorporates an adjustment mechanism that allows the shape and rigidity to be dynamically changed. A sliding element can move along a guide structure to adjust the teat length, while a twisting element can rotate to adjust the teat width, enabling a single teat to adapt to different baby preferences without needing multiple different teats

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The teat is designed with multi-functionality by integrating adjustment capabilities for both length and width dimensions. This universal design allows one teat to perform the function of multiple different teats, providing adaptability to various baby preferences while reducing the number of separate products needed

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Device complexity

If a single teat design is used for all babies, then the device complexity is reduced, but the adaptability to different baby preferences deteriorates

Engineering Contradiction:
Improveteat structure simplicityVSAvoidsuitability for different babies
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The teat maintains a relatively simple base structure but incorporates dynamic adjustment capabilities through the sliding element for length control and twisting element for width control. This allows the simple base design to become adaptable to different babies when the adjustment mechanism is engaged

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If the teat shape is fixed during manufacturing, then the manufacturing precision is improved, but the adaptability to changing baby needs deteriorates

Engineering Contradiction:
Improveteat shape consistencyVSAvoidadjustability to changing needs
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The teat is manufactured with precise baseline dimensions and incorporates adjustable elements that can modify the shape after manufacturing. The sliding element adjusts length and the twisting element adjusts width, allowing the precisely manufactured base teat to adapt to changing baby needs without compromising the original manufacturing precision

Inventive Principle:
Principle #15Dynamics

AI summary

A teat unit for a feeding bottle (5) has a teat (1) and an adjusting mechanism (2, 3). The teat (1) can be altered in shape and/or degree of rigidity by means of this adjusting mechanism (2, 3). This makes it possible to use one and the same teat (1) in different forms. The teat can be adapted to the baby's requirements prior to, or during, sucking.
