Solution Overview

Problem

Conventional bottle teats for infants and small children often experience difficulties in achieving a reliable seal due to the vacuum created during suction, leading to potential leakage and discomfort, especially with complex cap designs that are hard to clean and prone to leaks.

Innovation Solution

A bottle teat with a dome-shaped palate-contacting region featuring an elevated surface containing the drinking hole, which allows for easy alignment and sealing with a cap's inwardly bulging sealing surface, reducing friction and ensuring a secure seal, along with a thin region for comfortable palate contact and optional ribbed teat sleeve for stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a complex cap design with membrane is used to seal the drinking hole, then sealing capability is improved, but device complexity increases and ease of cleaning deteriorates

Engineering Contradiction:
Improvesealing capabilityVSAvoidcap structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the sealing function from a complex membrane-based cap system and relocates it to a simple elevated surface on the bottle teat itself. The elevated surface acts as the primary sealing element, eliminating the need for complex cap membranes while maintaining reliable sealing capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The bottle teat's elevated surface performs the sealing function autonomously through its own geometric feature, without requiring additional sealing components in the cap. The elevated surface self-aligns and self-seals against the cap's sealing surface, simplifying the overall system.

Inventive Principle:
Principle #25Self-service

2Reliability

If a membrane-based sealing system is used, then sealing capability is improved, but ease of operation deteriorates due to alignment difficulties

Engineering Contradiction:
Improvesealing capabilityVSAvoidcap assembly ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent employs a dome-shaped elevated surface with specific curvature characteristics that facilitate automatic alignment and sealing. The curved geometry of the elevated surface complements the corresponding sealing surface in the cap, enabling easy assembly without precise alignment requirements.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The elevated surface is pre-formed as an integral part of the bottle teat during manufacturing, with its sealing geometry already optimized. This preliminary preparation eliminates the need for complex alignment procedures during assembly, as the sealing surfaces are designed to mate automatically.

Inventive Principle:
Principle #10Preliminary action

3Shape

If the drinking hole is positioned in a side surface at a sharp angle, then orthodontic shaping is achieved, but sealing reliability deteriorates due to slight contact pressure

Engineering Contradiction:
Improveorthodontic shapeVSAvoidsealing reliability
Core Design Contradiction:
ShapeVSReliability

Solution Approach 1:

The patent transitions the drinking hole from a side-surface position to a position on a dome-shaped elevated surface. This dimensional change allows the drinking hole to be properly positioned while the elevated surface provides a large, flat sealing area that ensures reliable contact pressure distribution.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The elevated surface creates a localized region with enhanced sealing properties. While the drinking hole maintains its functional position, the elevated surface above it provides concentrated contact pressure and a large sealing area, ensuring reliable sealing without compromising the orthodontic shaping of the teat.

Inventive Principle:
Principle #3Local quality

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 solution provides a simple, reliable, and comfortable sealing mechanism that prevents leakage and is easy to clean, enhancing the usability and safety of bottle teats for infants and small children.

Implementation Method 1

The bottle teat is made of soft elastic material and the elevated surface on the outside of the palate-contacting region is pressed in a sealing manner against an inwardly bulging sealing surface on the inside of the bottom of a cap

Methodology Applied
Scientific EffectElastic deformation: Elasticity

Implementation Method 2

When suction is exerted on the suction part, a vacuum arises in the container which makes it difficult to withdraw the liquid and can cause a soft elastic bottle teat to collapse

Methodology Applied
Scientific EffectVacuum pressure: Vacuum
