Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum generator systems face issues with air leakage leading to vacuum environment destruction, slow operation, and complex structures due to the need for external valves to break the vacuum, making them inconvenient and difficult to maintain.
Innovation Solution
A vacuum breaking device with a main housing featuring an air supply port, vacuum interface and generating chambers, a pilot valve controlled by an electromagnetic pilot valve assembly, and a pneumatic on-off valve, along with an adjusting mechanism for the throttle passage, allowing for efficient control of vacuum states and quick breaking of the vacuum environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If natural air leakage is used to break vacuum after closing the vacuum generating path, then the vacuum environment is destroyed, but the breaking speed is relatively slow
Solution Approach 1:
The patent introduces a pilot valve as an intermediary component that uses a small amount of compressed air to control the opening of the main vacuum breaking valve. This mediator mechanism enables rapid vacuum breaking without requiring direct large-scale air introduction, thus improving breaking speed while maintaining reasonable structural complexity.
Solution Approach 2:
The patent employs pneumatic principles by using compressed air through the pilot valve to actuate the vacuum breaking valve. The pneumatic pressure differential created by the pilot valve enables rapid opening of the main valve, achieving fast vacuum breaking through fluid pressure control rather than mechanical actuation alone.
2Ease of operation
If an external on-off valve is used for air jet to break vacuum, then the vacuum can be broken, but the structure becomes complicated and operation becomes troublesome
Solution Approach 1:
The patent merges the vacuum breaking function directly into the vacuum generator body by integrating the pilot valve and vacuum breaking valve within the main housing. This combination eliminates the need for separate external valves and control systems, simplifying both the overall structure and the operation required to break vacuum.
Solution Approach 2:
The vacuum generator is designed with multi-functionality by incorporating both vacuum generation and vacuum breaking capabilities within a single integrated device. The pilot valve serves dual purposes in controlling both vacuum generation and vacuum breaking operations, reducing the need for separate specialized components.
3Reliability
If soft material is used for sucking at the vacuum port to maintain vacuum, then vacuum maintenance is good, but automatic air leakage is impossible
Solution Approach 1:
The patent employs dynamic control of the vacuum state through the pilot valve mechanism. The soft sealing material maintains vacuum reliability during normal operation, while the pilot valve dynamically introduces air when activation is required, enabling both reliable vacuum maintenance and controlled vacuum breaking without compromising either function.
