Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum generation devices face limitations in flow rate sensitivity during vacuum destruction, component size scalability, and ease of maintenance, as well as complexity in automatic processing operations, with existing connection systems causing deformation and operational issues.
Innovation Solution
A vacuum-keeping multistage vacuum-generating and vacuum-destructing valve design featuring a vacuum-destructing two-port two-position valve in a flow conducting passage, a reversal preventing valve, and a secure connection plug system with insertion holes and clips, along with side seats for fluid channels and bolt fixation, allowing for enhanced flow rate sensitivity, easy replacement, and flexible multi-unit assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the capacity of the vacuum generation device is increased, then the vacuum generation capability is improved, but the size of the vacuum-destructing valve and other components must be increased by a lot
Solution Approach 1:
The flow conducting passage is segmented into multiple paths: a first passage for vacuum generation and a second passage for vacuum destruction. This segmentation allows the vacuum-destructing valve to operate independently with a smaller size while the overall device capacity is determined by the combined system architecture rather than being constrained by a single large valve component.
2Strength
If a barbed fixing member is set in completely tight engagement with the through hole, then the connection strength is improved, but replacement of the connection plug becomes unavailable
Solution Approach 1:
The connection system transitions from a static tight-engagement design to a dynamic system with controlled engagement. The barbed fixing member is designed with specific geometric features that allow it to be inserted and secured tightly during normal operation, while also permitting controlled removal through a specific motion or mechanism, thus providing both strong connection and replaceability.
3Strength
If an excessively large size of the barbed fixing member is used, then the coupling strength is improved, but deformation at the coupling site occurs
Solution Approach 1:
The barbed fixing member incorporates local quality variations in its structure, with different sections having different properties. The barb portions are designed with optimized dimensions and shapes that concentrate the coupling strength where needed while distributing the mechanical stress to avoid deformation at critical coupling sites. This localized optimization allows achieving high coupling strength without excessive overall size.
4Object-affected harmful factors
If an excessively small size of the barbed fixing member is used, then deformation at the coupling site is avoided, but the strength of coupling is reduced
Solution Approach 1:
The barbed fixing member utilizes composite structural design combining different geometric forms and material properties in a single component. The structure integrates rigid barb portions for strong engagement with softer or more flexible sections for stress distribution, creating a composite structure that achieves both high coupling strength and resistance to deformation without requiring excessive size.

Function Achieved in This Case
The solution enhances the sensitivity of vacuum destruction responses, simplifies maintenance and assembly, and supports more complex automatic processing operations by increasing the flow rate of pressure fluid and allowing for secure, removable connections and flexible multi-unit configurations.
Implementation Method 1
When the pneumatic source (904) moves through the fluid passage (905) to pass through the operation of the vacuum-generating valve (906), an existing positive pressure is converted into a negative pressure, so that the vacuum port (902) generates a vacuum suction force
Implementation Method 2
the pneumatic source (904) flowing into the inlet opening (9071) of the vacuum-destructing valve (907) drives a valve outlet port (9073) to have the pneumatic source (904) to discharge through the outlet opening (9072) thereby releasing the vacuum

AI summary
A vacuum-keeping multistage vacuum-generating and vacuum-destructing valve includes a main body, which includes an introduction port, a vacuum port, a discharge port, and a vacuum-generating valve, in combination with a vacuum-destructing valve. The vacuum-destructing valve is arranged in combination with a flow conducting passage formed in the main body and connected to the vacuum port to allow a pressure fluid received through the introduction port to partly flow through the vacuum-destructing valve, and a vacuum-destructing two-port two-position valve is arranged in the flow conducting passage to increase flow rate of the pressure fluid passing therethrough to make a response of the vacuum port more sensitive in switching to a vacuum-destructing state. The ports of the main body are arranged in a detachable manner to increase service efficiency and ease part replacement. Two side seats are arranged to couple multiple such main bodies together to cope with complicated automatic processing operations.
