Vacuum Absorber With Rotating Cover And Adhesive Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum absorbers face challenges in achieving a strong and stable attachment to various surfaces due to weak engaging forces between components and difficulties in maintaining a vacuum state on rough or protruded surfaces, leading to inefficient assembly and operation.
Innovation Solution
The vacuum absorber incorporates a rotatable cover with fixing pieces and locking protrusions, a height-adjusting member with guide and locking features, and an adhesive member, allowing for enhanced engagement and adhesion to both smooth and protruded surfaces by creating a vacuum state between the suction plate and the attachment surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If engaging protrusions are used to assemble components, then assembly is simplified, but the engaging force becomes weak and components may disengage
Solution Approach 1:
The cover is designed to rotate relative to the suction plate, transforming the static engagement into a dynamic system. The rotation mechanism allows the cover to be positioned at different angles while maintaining firm engagement through the interaction between the rotating cover and the height-adjusting member, preventing disengagement while preserving assembly simplicity.
Solution Approach 2:
The engaging structure is divided into multiple independent elements: engaging protrusions on the cover, corresponding engaging holes on the suction plate, and guide portions on the height-adjusting member. This segmentation allows each component to perform its specific function - the protrusions and holes provide engagement points, while the guide portions ensure proper alignment and movement guidance, collectively achieving both easy assembly and strong engaging force.
2Reliability
If only vacuum absorbing method is used, then attachment to smooth surfaces is effective, but attachment to rough or protruded surfaces fails
Solution Approach 1:
The vacuum absorber integrates two attachment methods into a single device: the vacuum absorbing method through the suction plate and the adhesion method through the adhesive member. This multi-functionality allows the device to attach reliably to both smooth surfaces (using vacuum) and rough or protruded surfaces (using adhesion), enhancing both vacuum attachment stability and surface type compatibility.
Solution Approach 2:
The adhesive member acts as an intermediary between the suction plate and rough or protruded surfaces, filling gaps and creating a bonding interface where vacuum alone would fail. The adhesive member compensates for surface irregularities, allowing the vacuum absorber to maintain reliable attachment across diverse surface types.
3Device complexity
If the cover is fixed without rotation, then component engagement is simple, but operation flexibility is reduced
Solution Approach 1:
The cover is designed to rotate relative to the suction plate, transforming the static engagement into a dynamic system. The rotation mechanism allows the cover to be positioned at different angles while maintaining firm engagement through the interaction between the rotating cover and the height-adjusting member, preventing disengagement while preserving assembly simplicity.

Function Achieved in This Case
This configuration ensures firm and easy engagement of components, improving assembly efficiency and maintaining a stable vacuum attachment to different surfaces for extended periods.
Implementation Method 1
the vacuum absorbed is pushed toward the attachment surface, thus deflating the air in a space between the attachment surface and the suction plate to the outside of the suction plate. Thereafter, a vacuum state can be made between the attachment surface and the suction plate.
Implementation Method 2
an adhesive member which has a through hole to attach the suction plate to the attachment surface
