Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air stop valves in air sealing bodies fail to effectively prevent backflow of air, leading to a loss of buffering function over time due to their linear design, which allows air to circulate and escape.
Innovation Solution
A nonlinear air stop valve structure featuring two narrower inner membranes with arcs and breaches, arranged symmetrically to guide air flow and block backflow, utilizing a heat-resistant material for improved sealing and airflow management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a linear path structure is adopted in the air stop valve, then the manufacturing is simple, but the air can flow back along the linear path to the outside
Solution Approach 1:
The patent applies curvature by replacing the linear path with a nonlinear curved path structure. The air channel is designed to follow a curved trajectory rather than a straight line, making it difficult for air to flow back along the original path. This curved configuration maintains manufacturing simplicity while effectively preventing backflow, resolving the contradiction between structural simplicity and air sealing performance.
2Productivity
If a one-way air stop valve is used to lock air, then the air sealing body can be inflated, but the air cannot be locked for long time
Solution Approach 1:
The nonlinear curved path structure prevents air from circulating back to the original path and escaping. The curved configuration creates a one-way flow pattern that allows easy inflation while preventing long-term air escape, thereby extending the air locking duration while maintaining inflation capability.
Solution Approach 2:
The valve structure is designed in advance to prevent backflow by creating a nonlinear path that inherently resists reverse flow. The curved configuration and associated structural features are pre-configured to block air from returning to the inlet, ensuring long-term air retention while maintaining the ability to inflate when needed.
3Reliability
If a linear blocking structure with turning is adopted, then the air backflow is blocked, but the inflation operation becomes unsmooth
Solution Approach 1:
The patent resolves this contradiction by using a curved nonlinear path instead of a linear path with sharp turns. The curved configuration allows air to flow smoothly during inflation without abrupt direction changes, while still effectively blocking backflow. This eliminates the operational unsmoothness caused by linear blocking structures with turns.

AI summary
A nonlinear air stop valve of an air sealing body includes an inner member having left arcs on one side and right arcs on the other side, and both left and right arcs are asymmetrically arranged sideway, and a breach is formed at the bottom of the left and right arcs and on a concave arc surface, and left and right arcs are arranged from top to bottom, such that air entering from an air inlet at the top of the inner membrane flows along an upper arc of the left and right arcs to a lower arc and is blocked by the concave arc surface to flow to the breach and pass through the right arc, breach, left arc and breach in turn from right to left or from left to right into an air outlet at the bottom of the inner membrane and enter into the sealing body.
