Bottle Teat Lip Valve Design for Vacuum Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottle teats face challenges in production complexity and vacuum resistance, with slot valves being difficult to produce and prone to opening under child suction, leading to liquid flow issues.
Innovation Solution
A bottle teat design featuring a lip valve integrated in the nipple flange or sleeve, which is open by default and closes upon bottle attachment, allowing controlled opening pressure independent of axial forces, simplifying production and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a slot valve is used in the nipple sleeve, then the ventilation function is provided, but the production complexity increases and the valve opens too easily under child suction
Solution Approach 1:
The patent changes the geometric parameters of the valve opening from a slot configuration to a rounded opening with specific radius characteristics. The rounded opening has a first radius at the narrowest point and a second radius at the wider point, creating a controlled flow path that requires higher suction pressure to open compared to a slot valve, thus improving vacuum resistance while maintaining production simplicity
Solution Approach 2:
The valve opening is segmented into distinct geometric zones with different radii (first radius at the narrowest point, second radius at the wider point). This segmentation creates a progressive flow path that controls the opening pressure characteristics, allowing the valve to remain closed under normal child suction while opening reliably when needed
2Reliability
If a slot valve is used, then ventilation is enabled, but the sealing lips only rest with slight pressure causing premature opening
Solution Approach 1:
The patent modifies the geometric parameters of the valve opening to have a rounded shape with specific radius characteristics. The first radius at the narrowest point and the second radius at the wider point create a controlled flow path that requires higher suction pressure to open, thereby improving vacuum resistance and preventing premature opening under child suction while maintaining ease of operation
3Reliability
If additional production steps are added to create slot valves, then ventilation function is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The valve opening is segmented into distinct geometric zones with different radii that can be formed in a single injection molding process. The rounded opening with its first and second radii creates the necessary ventilation function without requiring additional production steps, maintaining manufacturing simplicity while improving reliability
Solution Approach 2:
The patent changes the geometric parameters from a slot configuration requiring additional processing to a rounded opening that can be formed directly in injection molding. This parameter change eliminates additional production steps while maintaining the ventilation function, thereby improving ease of manufacture
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 design ensures reliable vacuum resistance and easy manufacturing, maintaining liquid flow without excessive child suction, and facilitates easier cleaning by eliminating the need for additional production steps.
Implementation Method 1
a lip valve that is opened when the nipple flange is not fastened to a bottle by means of a fastening ring, and that is arranged in the nipple flange or the nipple sleeve in a deforming area next to the contact area so that, when the nipple flange is fastened by means of the fastening ring to a bottle, the deformation of the deforming area that arises from pressing the fastening ring against the contact area closes the valve
Implementation Method 2
In response to suction, a vacuum arises in the bottle that makes it difficult to withdraw the liquid. The bottle teat can collapse from the vacuum, causing the nipple to slip into the bottle.
