Bite-safe artificial teat with braided fiber mesh
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional artificial teats are inadequate in mimicking the natural teat's elasticity and function, leading to choking hazards due to potential separation of parts and requiring a different suck-swallow-breathe rhythm, which can cause 'nipple confusion' and hinder breast-feeding continuation.
Innovation Solution
A bite-safe artificial teat design featuring a nipple portion made of a soft elastomer with a braided fiber mesh tube that elongates like a natural teat, preventing separation and maintaining deformability, combined with a base portion that resists biting and choking hazards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional artificial teats are made with fixed-orifice holes and higher hardness material (Shore A 50-70), then manufacturing precision and structural stability are improved, but the ability to mimic natural teat elasticity and function deteriorates
Solution Approach 1:
The patent changes the material hardness parameter from conventional Shore A 50-70 to a softer range, and transforms the fixed-orifice structure into a deformable membrane with variable orifices that can open and close dynamically, mimicking natural teat function
Solution Approach 2:
The patent introduces dynamic characteristics by creating a deformable membrane that can change shape and open/close orifices in response to infant sucking actions, replacing the static fixed-orifice design with a dynamically responsive structure
2Strength
If conventional artificial teats use higher hardness material (Shore A 50-70), then structural strength and resistance to deformation are improved, but the ability to elongate and mimic natural teat function deteriorates
Solution Approach 1:
The patent changes the material hardness parameter to enable significant elongation (up to twice the relaxed length) while maintaining sufficient strength through the fiber reinforcement network that distributes and manages mechanical stresses
3Ease of manufacture
If conventional artificial teats are designed with fixed structure, then manufacturing simplicity is improved, but the ability to prevent choking hazards through bite-resistance deteriorates
Solution Approach 1:
The patent creates a composite structure combining soft elastomer material with an embedded fiber reinforcement network, achieving both bite-resistance to prevent choking and the desired softness for mimicking natural teat function
Solution Approach 2:
The patent segments the reinforcement function from the base material by introducing a separate fiber network structure that provides bite-resistance while allowing the elastomer matrix to maintain softness and deformability
4Duration of action of stationary object
If conventional artificial teats use harder material, then durability and resistance to wear are improved, but the ability to transmit tongue forces to hard palate for oral cavity development deteriorates
Solution Approach 1:
The patent changes the material hardness parameter to a softer range that enables effective force transmission to the hard palate for oral cavity development while maintaining durability through the fiber reinforcement network that prevents material degradation
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 teat effectively mimics the natural teat's function, reducing choking hazards and allowing for a consistent suck-swallow-breathe rhythm, promoting successful breast-feeding and preventing 'nipple confusion' by ensuring the nipple portion remains attached and deformable.
Implementation Method 1
a braided fiber mesh tube that elongates like a natural teat, preventing separation and maintaining deformability
Implementation Method 2
Repeated compression of the nursing mother's nipple against the infant's hard palate will cause, over time, a controlled deformation of the hard palate

AI summary
A bite-safe artificial nipple is constructed of polymeric materials sufficiently soft and elastic to replicate a nursing mother's nipple tissue. Added to the soft, elastic matrix phase is a braided fibrous mesh tube to prevent a small bitten-off portion of the nipple from becoming separated from the rest of the teat, thereby preventing a choking hazard. The braided fibrous mesh tube is arranged in a very specific configuration, so that it experiences neither tension nor compression as the teat is compressed or elongated in use and so does not act to “reinforce” the soft, elastic matrix phase which would otherwise create a classic load-transfer composite destroying the soft, elastic properties of the matrix phase needed for the desired functioning of the artificial teat.
