Baby Teat with Flange Depression for Pressure Equalization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drinking teats face challenges in production and cleaning complexity, along with inefficient pressure equalization, leading to difficulties in maintaining negative pressure during feeding, which can cause the teat to slip into the container and disrupt feeding comfort.
Innovation Solution
A drinking teat design featuring a hollow teat part with a depression on the top side of the teat flange, allowing the annular flange of the fastening ring to press against the top side while maintaining a distance from the bottom, enabling sufficient flexibility for air to flow in and equalize pressure when a certain negative pressure is reached, thus creating a novel ventilation valve that is easier to produce and clean.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a ventilation valve is added to equalize pressure, then the teat stability is improved, but the device complexity increases
Solution Approach 1:
The ventilation valve is integrated directly into the teat flange structure, merging the ventilation function with the existing flange component. This eliminates the need for separate ventilation mechanisms while maintaining pressure equalization capability, thus improving stability without significantly increasing device complexity
Solution Approach 2:
The ventilation valve automatically opens when negative pressure differential exceeds a certain threshold, allowing air to flow from the environment into the vessel. This self-activating mechanism equalizes pressure without requiring external control systems, maintaining simplicity while ensuring teat stability
2Reliability
If a complex ventilation valve structure is used, then the pressure equalization efficiency is improved, but the manufacturing cost increases
Solution Approach 1:
The ventilation valve utilizes the elastic properties of the teat flange material to create a pressure-sensitive opening mechanism. By changing the physical state response of the material to pressure differential, the valve opens automatically when needed, achieving reliable pressure equalization through material property optimization rather than complex mechanical structures
Solution Approach 2:
The teat flange is designed with sufficient flexibility in specific regions to allow the bottom to bulge and create ventilation channels. This flexible membrane approach replaces rigid mechanical valve components with a simple, easily manufacturable elastic structure that achieves the same pressure equalization function
3Reliability
If the teat flange is made rigid for stable fastening, then the fastening reliability is improved, but the ventilation function deteriorates
Solution Approach 1:
The teat flange is designed with differentiated local properties: the outer peripheral region maintains sufficient rigidity for stable fastening to the vessel mouth, while the inner region (where the depression is located) has increased flexibility to allow bulging and ventilation channel formation. This local quality differentiation resolves the contradiction between fastening reliability and ventilation function
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 effectively equalizes pressure, enhances drinking comfort by opening the ventilation valve at a specific negative pressure, and reduces manufacturing and cleaning costs, ensuring even feeding without pressure buildup disturbances.
Implementation Method 1
When sucking on the suction part, a negative pressure is created in the container
Implementation Method 2
the suction flange has sufficient flexibility at least in the region of the recess, so that the floor bulges

AI summary
Teat in particular for babies and toddlers, having a hollow sucking part, which has at least one through-passage opening for liquid food and is connected, at the bottom, to a substantially circular-disc-shaped teat flange, which serves for fastening on the mouth opening of a container by means of a fastening ring with a circular-disc-shaped annular flange which engages over the teat flange and is intended for pressing the underside of the teat flange flatly against the end periphery of the mouth opening, and having at least one depression on the upper side of the teat flange, said depression extending in the radial direction of the teat flange, and therefore, when the teat is fastened on the mouth opening of a container, an annular flange of a fastening ring, said annular flange pressing against the upper side of the teat flange, is spaced apart from the upper side of the base of the depression and the teat flange, at least in the region of the depression, has sufficient flexibility for the base to arch upwards and for air to flow radially from the outside, beneath the upwardly arched base of the depression, into the container when the teat has been fastened on the mouth opening of a container and negative pressure is being generated in the container as a result of the sucking part being sucked.
