Sucker With Flexible Lip Edge For Non-Polished Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suckers fail to maintain sucking force and load capability when applied to non-polished surfaces, as the internal air chamber communicates with the outer side, leading to a loss of suction effect.
Innovation Solution
A sucker structure featuring a flexible disc body with a tapered annular wall and an air-sucking passage that creates a negative pressure environment, allowing the lip edge to contact the surface at a gentle angle, increasing the contact area and preventing air escape, thus maintaining suction on non-polished surfaces like wooden boards and bricks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional sucker is applied to a non-polished surface, then the sucker can be used on various surfaces, but the internal air chamber communicates with the outer side causing loss of sucking effect
Solution Approach 1:
The patent employs a flexible disc body with a tapered annular wall that forms a lip edge, which freely flexes to adapt to non-polished surfaces while maintaining airtight sealing. This flexible structure allows the sucker to conform to rough surfaces without compromising the sealing of the air chamber, thus resolving the contradiction between surface adaptability and sucking force maintenance.
Solution Approach 2:
The lip edge of the disc body is designed to be freely flexible, allowing it to dynamically adapt its shape and angle of contact with the surface. This dynamic flexibility enables the sucker to maintain effective sealing on various surface types, from polished to rough, preventing air leakage while preserving sucking capability.
2Reliability
If the lip edge is made freely flexible to increase contact area, then the sucking effect is improved, but the structure complexity increases
Solution Approach 1:
The patent uses a simple yet effective flexible disc body structure with a tapered annular wall that naturally forms a lip edge. This single flexible component achieves both increased contact area and improved sucking effect without requiring complex multi-part mechanisms, thus minimizing structure complexity while maximizing performance.
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 sucker achieves an excellent sucking effect and higher load capability, capable of adhering to various surfaces including rough ones, with the flexibility of the lip edge ensuring a larger contact area and airtight attachment, while maintaining negative pressure to enhance suction.
Implementation Method 1
The sucker operates in a principle that the air pressure in the sucker is smaller than the atmospheric pressure so as to create sucking force
Implementation Method 2
The air in the air chamber is prevented from escaping from the disc body
Implementation Method 3
Thanks to the flexibility of the lip edge, when the sucker sucks a surface of an object, the lip edge contacts the surface by a relatively gentle angle

AI summary
A sucker includes: a main body having a bottom face formed with an annular abutment; a disc body made of a flexible material having a tapered annular wall, the disc body being disposed under the bottom face of the main body, an outer circumference of the annular wall being formed with a freely flexible lip edge positioned below the annular abutment face; an air chamber being formed in the disc body; and an air-sucking passage having a first end in communication with the air chamber of the disc body and a second end passing through the disc body and the main body to communicate with outer side. When the sucker sucks a surface of an object, the top face of the lip edge is in contact with the abutment face and supported thereby.
