Solution Overview

Problem

Existing teat units for baby bottles are limited in variability and cannot meet the needs of premature babies or infants with difficult drinking habits, as they often compromise on functionalities such as optimal milk flow, safe closing, ventilation, easy attachment, and ease of cleaning due to complex structures and high manufacturing costs.

Innovation Solution

A modular teat unit design consisting of a flexible teat, a dimensionally stable receiving head, and a base part connected via a detachable plug connection, allowing for flexible optimization of various functionalities without affecting others, enabling different teat and receiving head shapes, valve placements, and manufacturing cost reduction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a complex structure with multiple components is used to optimize specific functionalities (valve, ventilation, flow control), then the functional performance is improved, but the device complexity and manufacturing cost increase

Engineering Contradiction:
Improvefunctional performanceVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple functional components (valve, ventilation system, flow control elements, and teat) into a single integrated receiving head made of elastomeric material. This merging of previously separate components into one multifunctional unit reduces device complexity while maintaining all necessary functionalities for controlled milk flow, ventilation, and safe closing.

Inventive Principle:
Principle #5Merging (Combining)

2Device complexity

If the teat is attached directly to the bottle neck without an intermediate ring, then the device complexity is reduced, but the ease of attachment and removal deteriorates

Engineering Contradiction:
Improvestructure simplicityVSAvoidattachment ease
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The receiving head serves multiple functions simultaneously: it attaches to the bottle neck via threaded ring, holds the teat, provides ventilation, controls milk flow through integrated valve mechanisms, and ensures safe closing. This multifunctional design eliminates the need for separate intermediate components while maintaining ease of attachment and removal.

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

3Reliability

If thick-walled teat design is used to ensure durability and safe closing, then the reliability is improved, but the manufacturing difficulty and cost increase

Engineering Contradiction:
Improvesafe closingVSAvoidmanufacturing difficulty
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The receiving head is made of elastomeric material that provides both the necessary mechanical strength for safe closing and durability, while allowing for easier manufacturing compared to thick-walled rigid teat designs. The elastomeric material's inherent flexibility and strength properties achieve reliable sealing without requiring excessive wall thickness.

Inventive Principle:
Principle #40Composite materials
