Feeding Bottle Non-Return Valve Pressure Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing feeding bottles cause unbalanced pressure during feeding, leading to flatulence in babies and incomplete milk powder dissolution due to the need to balance atmospheric pressure and shake the bottle, which can result in air inhalation and foam formation.
Innovation Solution
A feeding bottle design featuring non-return valves with a tapered extension portion at the bottom to balance internal and external pressure and prevent laminar flow, ensuring air enters while liquid remains inside, and a detachable nipple assembly for easy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the feeding bottle uses a closed structure with only a small hole at the nipple for liquid to pass through, then the sealing performance is improved, but the internal pressure becomes unbalanced causing the liquid to become harder to suck out and requiring the baby to increase suction force
Solution Approach 1:
The feeding bottle is divided into separate functional components: the nipple assembly with liquid flow control and the body with air intake channels. This segmentation allows independent optimization of sealing (at the nipple) and pressure balance (at the body level through air holes), resolving the contradiction between sealing performance and suction ease.
Solution Approach 2:
Air holes in the body act as intermediaries to introduce atmospheric air into the bottle interior, mediating the pressure imbalance caused by the sealed nipple structure. This allows the sealed nipple to maintain its sealing function while the air holes compensate for pressure differences, making suction easier for the baby.
2Reliability
If the nipple is pulled out to allow air entry for pressure balance, then the pressure balance is improved, but the baby may simultaneously inhale air causing flatulence
Solution Approach 1:
The air intake function is segmented from the nipple and relocated to the bottle body. Air holes are provided in the body to allow atmospheric air to enter the bottle interior, maintaining pressure balance without requiring the nipple to be pulled out. This prevents the baby from inhaling air during feeding while still achieving pressure equilibrium.
Solution Approach 2:
Air holes in the body serve as intermediaries for pressure balance, allowing air to enter the bottle interior through the body wall rather than through the nipple. This intermediary air intake path prevents direct air inhalation by the baby while still achieving the necessary pressure balance for smooth liquid flow.
3Ease of manufacture
If the feeding bottle requires shaking to dissolve milk powder in water, then the dissolution function is achieved, but a large amount of foam is generated which is harmful to the baby
Solution Approach 1:
A vibration member is provided in the bottle body that can generate vibrations to agitate the liquid and promote milk powder dissolution. This mechanical vibration method replaces the traditional shaking method, achieving complete dissolution without generating excessive foam that would be harmful to the baby.
Solution Approach 2:
The manual shaking mechanism is replaced with a vibration member that generates controlled vibrations within the bottle. This substitution of mechanical systems allows for gentler, more controlled agitation of the liquid, achieving milk powder dissolution without the violent shaking that causes harmful foam formation.
4Object-affected harmful factors
If insufficient shaking is applied, then foam formation is reduced, but the milk powder dissolution becomes incomplete
Solution Approach 1:
The vibration member provides controlled mechanical vibrations that are sufficient to complete milk powder dissolution without requiring vigorous shaking. This ensures complete dissolution of milk powder while maintaining low foam generation, resolving the contradiction between dissolution completeness and foam reduction.
Solution Approach 2:
The dissolution mechanism is changed from macro-scale shaking to micro-scale vibrations. This parameter change in the agitation method allows for effective milk powder dissolution at lower energy levels, achieving complete dissolution without the excessive motion that creates harmful foam.

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 prevents flatulence by balancing pressure and accelerates milk powder dissolution by disrupting laminar flow, ensuring complete mixing without foam formation.
Implementation Method 1
the valve opens when the pressure inside the body is far less than the pressure outside the body
Implementation Method 2
a valve for allowing only the air outside to enter into the body
Implementation Method 3

AI summary
The present application relates to the technical field of baby appliance structure, and provides a feeding bottle, including: a body and at least one non-return valve integrally formed at a lower of the body. The non-return valve includes a connection portion that is connected at the body, an extension portion for disturbing the laminar flow state of the internal liquid of the body when shaking the body, and a valve for allowing only the air outside to enter into the body, the extension portion is tapered and extends along a surface of the body toward the interior of the body, the extension portion is located at the inside of the bottom of the body, or located above the inside of the bottom of the body and in the vicinity of the inside of the bottom of the body. This design can solve the problem that the structure of the existing feeding bottle may cause flatulence to the baby due to the unbalanced pressure and may easily lead to incomplete dissolution of the milk powder.
