Replaceable Vacuum Suction Pad Rubber Structure for Airtight Load Bearing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum suction pads face high replacement costs due to fixed rubber parts and structural weaknesses in the framework, leading to poor airtightness, deformation, and reduced load-bearing capacity.
Innovation Solution
A vacuum suction pad with a replaceable rubber part structure featuring a buckled connection, an independent air extraction chamber, and a buffer element, allowing for separate replacement of the rubber part and enhancing structural strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rubber part and framework are fixed together to prevent detachment, then the rubber part remains securely attached, but the rubber part cannot be replaced separately and maintenance costs increase
Solution Approach 1:
The rubber part is segmented from the framework through the detachable buckling connection. The flanging on the rubber part can be connected to or separated from the framework independently, allowing the rubber part to be replaced without replacing the entire framework assembly.
Solution Approach 2:
The connection between the rubber part and framework is made dynamic rather than static. The buckling connection allows the rubber part to be attached during operation for reliability, yet can be detached when needed for replacement, adapting the connection state based on operational requirements.
2Ease of manufacture
If a ringlike shell structure is formed around the cavity to create the vacuum chamber, then the cavity is formed for vacuuming, but the structural strength of the framework decreases leading to deformation and cracking
Solution Approach 1:
The framework is segmented into load-bearing structural members and the non-structural cavity-defining portion. The ringlike shell structure is separated from the main framework, allowing the framework to maintain its strength while the shell provides the necessary cavity formation for vacuuming.
Solution Approach 2:
Different parts of the structure are given different qualities: the framework maintains high structural strength for load-bearing, while the ringlike shell provides the local cavity formation functionality. This local differentiation allows each component to optimize its specific function without compromising the other.
