Vacuum Suction Assembly With Double Locking Against Shock Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum suction devices face challenges in maintaining a strong suction force over time, are inefficient to assemble, and have high manufacturing costs due to the use of springs, which degrade quickly and require frequent replacement, and are prone to separation from surfaces due to external shocks.
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 assembly efficiency, eliminating the need for springs and reducing component count, while the elastic stoppers provide a stable adhesion mechanism.
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 to form a vacuum-applied state, but the spring degrades quickly and requires frequent replacement, increasing maintenance costs and reducing reliability
Solution Approach 1:
The patent replaces the degradable spring with molded elastic stoppers made of elastic resin material. These stoppers are designed to be non-degradable and maintain their elastic properties indefinitely, eliminating the need for replacement. The stoppers are integrated into the height adjustment member through molding, creating a permanent solution that does not require maintenance.
Solution Approach 2:
The patent substitutes the mechanical spring system with an elastic material-based system. Instead of using a metal spring that degrades over time, the invention uses molded elastic stoppers that leverage the elastic properties of resin material. This substitution eliminates the degradation issue inherent in metal springs while maintaining the same functional outcome of lifting the suction plate.
2Reliability
If multiple components (cover, spring, height adjustment member) are used to achieve vacuum adhesion, then the suction force can be maintained, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple components into fewer integrated parts. The elastic stoppers are molded directly into the height adjustment member, eliminating the need for separate spring components. The fixing pieces are integrated into the cover. This merging reduces the number of parts that need to be assembled while maintaining the vacuum adhesion functionality.
Solution Approach 2:
The height adjustment member serves multiple functions: it provides the structural framework, incorporates the elastic stoppers for lifting the suction plate, and integrates the fixing groove for securing the fixing pieces. This multi-functionality reduces the overall component count and simplifies the assembly process.
3Device complexity
If the suction plate is pressed directly against the adhered surface, then the structure is simple, but the suction force is weak and the plate separates easily under external shocks
Solution Approach 1:
The patent introduces a dynamic lifting mechanism where the suction plate can be raised off the adhered surface by the elastic stoppers when the cover is rotated. This creates a controlled gap that maintains the vacuum seal while allowing the plate to be positioned optimally. The system transitions from a static pressed state to a dynamic adjustable state, improving resistance to separation forces.
Solution Approach 2:
The patent adds the vertical dimension of lifting to the horizontal pressing action. Instead of only pressing the plate against the surface, the elastic stoppers provide vertical lift that creates a gap. This dimensional change allows the vacuum seal to be maintained through the gap while reducing direct contact pressure points that could lead to separation under shock.
4Reliability
If the cover is rotated to wind the spring and lift the suction plate, then vacuum adhesion is achieved, but the assembly of the spring and cover is inconvenient and requires multiple rotations
Solution Approach 1:
The elastic stoppers are pre-formed through molding in the height adjustment member, eliminating the need for separate spring installation. The fixing groove is also pre-formed in the height adjustment member. This preliminary preparation of components through molding makes the assembly process straightforward and does not require multiple rotations or complex manipulation during assembly.
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 device achieves enhanced suction force, improved assembly efficiency, reduced manufacturing costs, and increased durability by using molded elastic stoppers, which prevent separation from surfaces and maintain adhesion even under external shocks, allowing for semi-permanent use.
Implementation Method 1
a plurality of elastic stoppers having a certain curved surface are formed in a height adjustment member... each of the fixing pieces moves along a curved surface of each of the elastic stoppers
Implementation Method 2
a state of a space between the adhered surface and the suction plate is changed to a vacuum-applied state, whereupon the suction plate is sucked by the adhered surface
