Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vacuum device discharges air from the container, then the storage time is extended and storage volume is reduced, but liquid inside the container may flow out and enter the vacuum device causing damage
Solution Approach 1:
The liquid receiver is divided into an upper receiving case and a lower liquid collecting case, with the buoyant device separating the two spaces. This segmentation allows liquid to be collected in the lower case while preventing it from reaching the vacuum device, resolving the contradiction between protection and structural complexity.
Solution Approach 2:
The buoyant device acts as an intermediary between the receiving case and the liquid collecting case. It automatically responds to liquid presence and activates the sealing mechanism, providing intelligent mediation without requiring complex external control systems.
2Reliability
If a liquid collection mechanism is added to prevent liquid damage, then the vacuum device is protected, but the device complexity increases
Solution Approach 1:
The buoyant device is designed to automatically respond to liquid presence and activate the sealing mechanism without external intervention. The magnetic component self-activates when liquid rises, eliminating the need for complex sensors, controllers, or power sources, thus maintaining simplicity while ensuring reliable liquid damage prevention.
Solution Approach 2:
The patent replaces complex electronic sensing and control systems with a simple magnetic field-based detection and actuation system. The magnetic component detects liquid presence and mechanically activates the sealing, substituting electronics with a simpler magnetic-mechanical system that achieves the same protective function with fewer components.
3Reliability
If the buoyant device is always positioned to seal the outlet, then liquid damage is prevented, but the normal operation of the vacuum device is hindered
Solution Approach 1:
The buoyant device is designed to be dynamically positionable between an initial position (allowing normal operation) and a clamping position (providing sealing). The device automatically transitions between these states based on liquid presence, ensuring both normal vacuum operation and liquid protection without manual intervention.
Solution Approach 2:
The buoyant device is preliminarily positioned to allow normal operation, but is designed to immediately counteract liquid intrusion attempts by transitioning to the sealing position when liquid is detected. This preliminary positioning with ready-to-act sealing capability ensures both ease of operation and liquid protection.
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
Effectively prevents liquid from overflowing into the vacuum device, thereby protecting it from damage.
Implementation Method 1
The buoyant device (1223) is movable between an initial position and a clamping position relative to the receiving case (1221)... After the buoyant device (1223) is driven by the liquid flowing out of the container (11A) to move from the initial position to an actuating position
Implementation Method 2
The magnetic component (12232) is configured to provide a magnetic force when the vacuum device (121) and the liquid receiver (122) are assembled with each other... the magnetic force drives the buoyant device to move from the actuating position to the clamping position

AI summary
A vacuum kit adapted for a container is provided and includes a vacuum device and a liquid receiver detachably assembled with the vacuum device. The liquid receiver includes a receiving case, a sealing component and a buoyant device. The sealing component is disposed adjacent to an outlet of the receiving case. The buoyant device is movable between an initial position and a clamping position relative to the receiving case. After the buoyant device is driven by the liquid flowing out of the container to move from the initial position to an actuating position between the initial position and the clamping position, the buoyant device can be driven by a magnetic force to move from the actuating position to the clamping position to clamp the sealing component by the buoyant device and the receiving case for sealing the outlet of the receiving case. Besides, a related vacuum product is also provided.
