Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional one-way valves for vacuum containers require a thick wall thickness to function properly, limiting their application to containers with thinner walls.
Innovation Solution
A one-way valve design featuring protrusions that resiliently deform to allow air evacuation and prevent ambient air entry, suitable for both thick and thin-walled containers, utilizing a resilient structure and channel mechanism to adapt to pressure differentials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional one-way valve is used, then air evacuation and sealing function are achieved, but the container wall thickness must be thick
Solution Approach 1:
The one-way valve is divided into multiple functional components: a lower portion with protrusions that engage with the container wall, an upper portion that forms the sealing surface, and a resilient structure that provides sealing force. This segmentation allows each component to be optimized independently, enabling the valve to function reliably on thin-walled containers without requiring thick walls for structural support.
Solution Approach 2:
The resilient structure in the one-way valve acts as a flexible element that can deform to create a seal against the container wall. This flexible component compensates for the thinness of the container wall, providing reliable sealing without requiring the wall to be thick. The resilient material allows the valve to adapt to the thin-walled surface and maintain sealing pressure.
2Adaptability or versatility
If the wall thickness is reduced for thin-walled containers, then versatility is improved, but conventional one-way valves cannot be mounted properly
Solution Approach 1:
The one-way valve incorporates a resilient structure that can dynamically deform and adapt to different container wall thicknesses. The protrusions can flex and adjust their position based on the container wall characteristics, allowing the valve to be mounted properly on both thin-walled and thick-walled containers. This dynamic adaptation eliminates the need for different valve designs for different container types.
Solution Approach 2:
The valve design changes the physical parameters of the mounting interface by using a resilient structure with specific elastic properties. This allows the valve to accommodate variations in container wall thickness within a certain range, transforming the rigid mounting requirement into a flexible adaptation process. The resilient material's deformation characteristics enable proper mounting on thin-walled containers where conventional rigid valves would fail.

Function Achieved in This Case
Enables effective air management in containers with thin walls, ensuring proper sealing and vacuum maintenance without the need for thick walls, enhancing versatility and functionality.
Implementation Method 1
The resilient structure is movable between a protruding state and a non-protruding state according to a differential pressure between an interior air pressure of the container and an exterior air pressure
Implementation Method 2
The upper portion is resiliently deformable. The plurality of protrusions are configured to be abutted by an inner surface of the container to resiliently deform the upper portion by an outer surface of the container
