Solution Overview
Problem
Existing vacuum sucker devices are complex in structure and inconvenient to operate, particularly in creating a negative pressure environment without the need for a vacuum pump.
Innovation Solution
A sucker base device with a compact structure featuring a suction cup, cup upper cover, and pressure driving nut, where a threaded rod connected to the suction cup is elevated by rotating a pressure driving nut to form a negative pressure between the suction cup and an object, allowing for easy attachment and detachment of objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a piston suction vacuum principle is used to create negative pressure without a vacuum pump, then the device can operate without additional vacuum equipment, but the structure becomes relatively complex and inconvenient to operate
Solution Approach 1:
The patent extracts the core function of creating negative pressure from the complex piston-suction-vacuum-system and implements it through a simple threaded rod lifting mechanism. The threaded rod directly lifts the suction cup to create negative pressure, eliminating the need for pistons, vacuum pumps, and associated complex components while maintaining the ability to create and control negative pressure effectively
Solution Approach 2:
Instead of using a piston to push air out and create negative pressure through vacuum suction, the patent inverts the approach by mechanically lifting the suction cup itself using a threaded rod. This inversion transforms the mechanism from active vacuum creation to passive negative pressure formation through direct mechanical elevation, significantly simplifying the structure
2Device complexity
If a threaded rod lifting mechanism is used to form negative pressure, then the structure becomes compact and easy to operate, but requires a screw-threaded connection system
Solution Approach 1:
The threaded rod serves multiple functions simultaneously: it acts as a lifting mechanism to elevate the suction cup, creates the negative pressure through the lifting action, and provides a controlled adjustment mechanism for the suction force. This multi-functionality eliminates the need for separate components for each function, achieving structural compactness without excessive manufacturing complexity
Solution Approach 2:
The threaded rod mechanism is self-contained and self-operating. By simply rotating the threaded rod, the system automatically converts rotational motion into linear lifting motion, which directly creates the negative pressure. The mechanism serves itself without requiring external vacuum pumps, motors, or complex control systems, making it both compact and manufacturable

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 device achieves a stable and efficient suction mechanism with a simple, compact design that is easy to operate, reducing costs and facilitating widespread adoption.
Implementation Method 1
A threaded rod is connected to an upper surface of the suction cup. The cup upper cover covers the suction cup. The threaded rod penetrates through a top surface of the cup upper cover and has a protrusion section exposed outside the top surface of the cup upper cover. The pressure driving nut is threaded to the protrusion section of the threaded rod
Implementation Method 2
A sucker is a kind of pendant which is adsorbed on an object due to pressure difference between internal and external atmospheric, or a tool for grasping an object. Vacuum sucker is a technology that maintains attachment of two objects through forming vacuum degree there-between

AI summary
The present invention discloses a sucker base device, which comprises a suction cup, a cup upper cover, and a pressure driving nut. A threaded rod is connected to an upper surface of the suction cup. The cup upper cover covers the suction cup. The rod penetrates through a top surface of the cup upper cover and has a protrusion section exposed outside the cup upper cover. The nut is threaded to the rod, is supported on the top surface of the cup upper cover, and is allowed to a rotary motion. By rotating the nut, the rod is driven to lift towards the cup upper cover, to form a negative pressure between the suction cup and a surface of sucked object. The device has compact and ingenious structure, lowered cost, and is readily to be realized and popularized.
