Moisture-Proof Storage Can With Slidable Vacuum Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional storage cans fail to maintain a moisture-free environment effectively due to complex structures and high assembly costs, and are prone to damage from external forces, especially when using air pump elements for vacuuming.
Innovation Solution
A moisture-proof storage can design featuring an inner holder, outer can, first check valve, and second check valve, allowing for a slidable variable space that creates a negative pressure environment by enlarging and reducing volume, mimicking an air pump operation, with simple manufacturing and assembly processes, and a filter to prevent particle entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an air pump element is directly designed on the cover of the storage can, then users can pump out air from the storage can, but the air pump element is prone to damage from external forces and has high structural complexity
Solution Approach 1:
The invention extracts the air pumping function from the cover structure and relocates it to a separate movable plunger component. The plunger can be manually pushed to create vacuum without being integrated into the cover, thereby simplifying the cover structure while maintaining the vacuum capability.
Solution Approach 2:
The storage can is divided into separate functional components: the cover, the plunger, the air channel, and the check valve. This segmentation allows each component to be optimized independently, reducing the complexity of any single part while maintaining overall functionality.
2Adaptability or versatility
If an air pump element is directly designed on the cover of the storage can, then users can pump out air from the storage can, but the manufacturing and assembly costs are high
Solution Approach 1:
By segmenting the vacuum function into separate components (plunger, air channel, check valve), each component can be manufactured independently using simpler processes, reducing overall manufacturing and assembly costs compared to integrating all functions into the cover.
Solution Approach 2:
The check valve automatically controls the direction of air flow without requiring complex control mechanisms. It passively allows air to be pumped out while preventing air from re-entering, reducing the need for complex assembly and control systems.
3Reliability
If the storage can uses a conventional airtight structure, then external air is blocked from entering, but the commodities still absorb moisture through repeated opening and closing
Solution Approach 1:
The invention creates a vacuum environment in advance within the storage can before the user needs to access it. By removing air and creating negative pressure, the system prepares a moisture-proof environment that remains effective even during repeated openings and closings, as the check valve prevents external air from entering.
Solution Approach 2:
The vacuum environment created inside the storage can acts as an inert atmosphere that prevents moisture from the external environment from reaching the commodities. This inert environment maintains moisture protection even when the can is opened and closed repeatedly.
4Adaptability or versatility
If the slidable variable space volume is enlarged by moving the outer can outwards, then a negative pressure environment is formed to suck out air, but user effort is required for sliding movement
Solution Approach 1:
The plunger is designed as a movable component that can be easily pushed and pulled along the air channel. This dynamic structure allows the user to create vacuum by simple linear motion rather than having to slide the entire outer can, significantly reducing the force required.
Solution Approach 2:
Instead of requiring the user to slide the outer can in a horizontal direction, the invention provides a vertical or axial dimension for the plunger to move along the air channel. This dimensional change makes the operation more convenient and requires less force.
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 maintains a moisture-free environment with reduced assembly costs and increased durability, allowing for easy operation and reduced user effort in maintaining the storage can's vacuum state.
Implementation Method 1
a negative pressure environment is formed in the slidable variable space to suck out the air in the storage space
Implementation Method 2
the actual volume of the slidable variable space is enlarged by holding and slidably moving the outer can outwards relative to the inner holder
Implementation Method 3
The first check valve is provided on the air hole and seals the air hole, and has an airflow direction towards the slidable variable space. The second check valve is provided on the air channel and seals the air channel, and has an airflow direction towards the exterior
Implementation Method 4
When the actual volume of the slidable variable space is reduced and the pressure is increased, the air in the slidable variable space is discharged to the exterior
