Aerating Bag Check Valve Prevents Air Backflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aerating bags suffer from air leakage through the release pipe and inefficient air inflation due to backflow of air into the body when filling an object, reducing their effectiveness.
Innovation Solution
The aerating bag incorporates a check valve with a slit and a detachable connector featuring a release pipe and cover, which prevents backflow by allowing air to enter the object while keeping it from returning to the bag, enhancing air inflation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a release pipe is added to the connector to allow air discharge, then air can be released from the body, but the release pipe components may be lost during operation
Solution Approach 1:
The release pipe is integrated into the connector as a unified structure rather than a separate component. The release pipe is formed on the connector and communicates with the inserting pipe, creating a combined assembly that prevents component loss while maintaining air discharge functionality.
Solution Approach 2:
The release pipe is nested within the connector structure, with the release pipe communicating with the inserting pipe that is inserted into the object. This nested arrangement ensures that the release pipe remains securely positioned within the connector assembly during operation.
2Productivity
If air is filled into the object through the intake valve, then the object can be inflated, but air may flow back into the body decreasing inflation efficiency
Solution Approach 1:
The check valve is extracted from the body and relocated to the connector, specifically positioned in the inserting pipe. This extraction prevents air backflow into the body by blocking the return path at the connector level, while the body structure remains simplified and focused on its primary inflation function.
Solution Approach 2:
The check valve acts as an intermediary component between the body and the object, positioned in the inserting pipe. It allows air to pass from the body to the object during inflation but prevents air from flowing back into the body, thereby mediating the air flow in one direction only and improving inflation efficiency.
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 easy operation with an anti-backflow effect, maintaining air pressure within the object and improving the overall efficiency of air inflation by preventing air from flowing back into the bag.
Implementation Method 1
The check valve is detachably mounted in the mounting recess of the connector and has an open end, a closed end and a slit. The slit is axially formed on the check valve near the closed end and communicates with a clearance between the connecting pipe of the connector and the check valve.
