Vacuum Suction Cup Locking Structure for Long-Lasting Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum suction devices face challenges in maintaining a strong suction force over time, are inefficient in assembly, and incur high manufacturing and replacement costs due to the use of springs, which degrade quickly and require frequent rotation for initial assembly, leading to inconvenient usage and increased costs.
Innovation Solution
The vacuum suction device incorporates a cover with fixing pieces that move along curved surfaces of elastic stoppers, forming a double lock structure to enhance suction force and prevent separation from the adhered surface, eliminating the need for springs and simplifying assembly by using molded elastic stoppers integrated with the height adjustment member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring is used to maintain vacuum suction force, then the suction plate can be lifted and adhered to the adhered surface, but the spring is prone to performance degradation over time and requires replacement
Solution Approach 1:
The invention extracts and eliminates the spring component from the vacuum suction device. Instead of using a spring to maintain the lifting force, the patent uses a rotatable cover that directly lifts the suction plate through a lifting protrusion, removing the reliability issues associated with spring degradation while maintaining the vacuum adhesion function.
Solution Approach 2:
The invention replaces the expensive and maintenance-prone spring with a simple, durable rotatable cover mechanism. The cover can be easily rotated to lift and lower the suction plate without any elastic components that degrade over time, effectively using a simple mechanical advantage instead of a consumable elastic element.
2Reliability
If a spring mechanism is used for adhering the suction plate, then vacuum suction can be achieved, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The invention removes the complex spring mechanism and its associated assembly steps (winding, positioning, securing). The simplified design uses a rotatable cover with a lifting protrusion that directly interacts with the suction plate, eliminating multiple components and assembly operations while maintaining reliable vacuum adhesion.
Solution Approach 2:
The invention merges the lifting function and the adhesion control function into a single rotatable cover operation. By combining these functions, the patent eliminates the need for separate spring mechanisms and their complex assembly requirements, reducing the overall device complexity and assembly time.
3Device complexity
If the suction plate is directly pushed to the adhered surface, then the structure is simple, but the suction force is weak and the plate is easily separated
Solution Approach 1:
The invention introduces a dynamic lifting mechanism where the rotatable cover can be rotated to lift the suction plate, creating a dynamic system that adjusts the plate's position relative to the adhered surface. This dynamic capability allows the plate to be pressed firmly against the surface for strong adhesion while maintaining structural simplicity through the use of a single rotating component.
Solution Approach 2:
The invention adds a rotational dimension to the simple push structure. By rotating the cover around a vertical axis, the lifting protrusion moves in a circular path to lift and lower the suction plate, transforming a simple linear push into a controlled dimensional movement that enhances suction force without significantly increasing structural complexity.
