Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vacuum pump is used to exhaust air from the storage container, then the vacuum state can be achieved, but the assembly cost and structural complexity increase
Solution Approach 1:
The patent removes the vacuum pump from the system entirely, extracting the complex mechanical component and replacing it with a simple manual pressing mechanism. The pressing part directly compresses air from the storage container through the tray component, eliminating the need for a separate vacuum pumping system and its associated complexity.
Solution Approach 2:
The system uses the user's manual pressing action to create the vacuum effect. The pressing part, when pressed down, directly compresses air from the storage container through the tray component, allowing the user's own action to serve the vacuum creation function without requiring external powered equipment.
2Reliability
If a vacuum pump is used to create vacuum state, then the vacuum function is achieved, but the assembly cost increases
Solution Approach 1:
The patent replaces expensive vacuum pump equipment with simple, inexpensive components including a pressing part, tray component, and one-way valve. These simple components can be manufactured at low cost and replaced easily if needed, significantly reducing the overall assembly cost while maintaining the vacuum function.
Solution Approach 2:
By removing the vacuum pump from the system, the patent eliminates the most expensive component. The remaining components (pressing part, tray, one-way valve) are simple and inexpensive, dramatically reducing the total assembly cost while preserving the essential vacuum creation capability.
3Reliability
If a vacuum pump with airtight flow paths is used, then the vacuum state is achieved, but the structure becomes complicated and difficult to detach and clean
Solution Approach 1:
The patent divides the system into separate, easily detachable components: the storage container, the tray component with one-way valve, and the pressing part. This segmentation allows each component to be easily removed and cleaned independently, eliminating the cleaning difficulties associated with integrated vacuum pump systems and complex airtight flow paths.
Solution Approach 2:
By removing the vacuum pump and its associated complex airtight flow path system, the patent leaves a simplified structure with minimal components. The remaining components have simple openings and surfaces that are easily accessible for cleaning, dramatically improving ease of operation and maintenance.
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 facilitates easy detachment and cleaning, with a simple structure that can achieve and release vacuum states efficiently.
Implementation Method 1
two one-way exhausters, wherein one of the one-way exhausters is inserted in the guiding hole to mount in the connecting tray component thereby forming a tray one-way exhaust passage communicating the accommodating space of the storage container and the tray inside space of the connecting tray component
Implementation Method 2
when the pressing part of the top cap is pressed to collapse and deform toward the tray inside space, the tray inside space is compressed by the pressing part and exhausts an exhaust air through the cap one-way exhaust passage to the outside space
Implementation Method 3
the accommodating space is driven by a pressure difference between the tray inside space and the accommodating space to exhaust through the tray one-way exhaust passage to the tray inside space so that the accommodating space becomes in a state approaching vacuum

AI summary
The invention discloses a vacuum container comprising a storage container, a connecting tray component, a top cap and two one-way exhausters. The connecting tray component air-tightly encloses a container opening of the storage container. The top cap has a pressing part, and the top cap encloses a tray opening of the connecting tray component in a manner that the pressing part is in a position corresponding to the tray opening. One of the one-way exhausters is inserted in a guiding hole of the connecting tray component to form a tray one-way exhaust passage. The other one-way exhauster is inserted in an exhausting hole to form a cap one-way exhaust passage.
