Anti-Flatulence Milk Bottle Air Return System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional milk bottles often create negative pressure that can lead to flatulence, hiccup, and discomfort in infants due to incomplete stomach development, and existing solutions like small-hole air valves are difficult to assemble, clean, and ineffective in balancing air pressure.
Innovation Solution
An anti-flatulence milk bottle design featuring a threaded connection with air returning covers and pipes that form confluence passages for external air to enter, balancing internal and external air pressure and preventing flatulence, while being simple in structure and easy to assemble and clean.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a small-hole air valve is used to reduce negative pressure, then air can enter the bottle body, but the air returning speed is slow and flatulence risk remains
Solution Approach 1:
The air returning system is divided into multiple independent air returning holes (at least two) in the nipple, each connected to air returning pipes. This segmentation increases the total air returning cross-sectional area and speed, resolving the contradiction between reliability and productivity by distributing the air returning function across multiple channels rather than a single small hole.
2Reliability
If a small-hole air valve is used, then air can enter the bottle body, but the structure is complex and difficult to assemble
Solution Approach 1:
The complex small-hole air valve is extracted and replaced with simple air returning holes directly formed in the nipple, connected to air returning pipes. This removes the complex valve mechanism while retaining the essential air pressure balancing function, resolving the contradiction between reliability and device complexity by using a simpler structural approach.
3Reliability
If a small-hole air valve is used, then air can enter the bottle body, but it is difficult to clean and easy to block
Solution Approach 1:
The single small-hole air valve is segmented into multiple air returning holes with corresponding air returning pipes. This segmentation makes the structure more open and accessible, allowing easier cleaning of each individual pipe and hole, thereby resolving the contradiction between reliability and ease of operation by improving maintenance accessibility.
4Productivity
If vacuum negative pressure is generated by suction, then milk can be drawn into the nipple, but the infant experiences flatulence and discomfort
Solution Approach 1:
Air returning pipes act as intermediaries that provide a dedicated pathway for external air to enter the bottle body and mix with milk at the bottom, rather than allowing air to be drawn in directly during suction. This intermediary mechanism resolves the contradiction between productivity and harmful factors by separating the milk delivery function from the air intake function, preventing flatulence while maintaining efficient milk flow.
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 effectively eliminates negative pressure in the milk bottle, allowing smooth milk suction and reducing flatulence discomfort in infants, with a balanced air pressure system that is easy to maintain and assemble.
Implementation Method 1
certain negative pressure is inevitably generated in the milk bottle... vacuum negative pressure generated by suction in the milk bottle... external air to enter the bottle body
