Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter devices for adsorption transport systems require complex valve structures and multiple check valves, leading to reduced pressure efficiency and increased costs due to their complicated internal flow path design when switching between negative and positive pressures.
Innovation Solution
A filter device with a shuttle valve that selectively switches between negative and positive pressure paths using a single valve disc, featuring parallel negative and positive pressure-side filters and a constriction portion in the positive pressure-side flow path to enhance responsiveness and prevent backflow of foreign substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple check valves are used to switch between negative and positive pressure paths, then the filter device can effectively remove foreign substances under both pressure conditions, but the internal flow path structure becomes complicated, reducing pressure efficiency and increasing costs
Solution Approach 1:
The patent combines the functions of multiple check valves into a single shuttle valve that can switch between negative pressure and positive pressure paths. This merging of functions reduces the number of components and simplifies the internal flow path structure while maintaining the ability to effectively filter foreign substances under both pressure conditions.
Solution Approach 2:
The shuttle valve is designed as a multi-functional component that can handle both negative pressure and positive pressure operations. This single valve performs the roles that would otherwise require multiple separate check valves, thereby reducing device complexity while maintaining reliability in foreign substance removal.
2Reliability
If multiple check valves are used to switch between negative and positive pressure paths, then the filter device can effectively remove foreign substances under both pressure conditions, but pressure efficiency is reduced due to the complicated structure
Solution Approach 1:
By merging multiple check valve functions into a single shuttle valve, the patent reduces the number of flow path transitions and pressure drops associated with multiple valves. This improves pressure efficiency while maintaining the effectiveness of foreign substance removal under both negative and positive pressure conditions.
3Reliability
If multiple check valves are used to switch between negative and positive pressure paths, then the filter device can effectively remove foreign substances under both pressure conditions, but various costs increase due to the complicated structure
Solution Approach 1:
The patent merges multiple check valve functions into a single shuttle valve assembly, reducing the total number of components that need to be manufactured and assembled. This simplification lowers manufacturing costs while maintaining the reliable performance of foreign substance removal under both pressure conditions.
Solution Approach 2:
The shuttle valve serves as a universal component that handles both negative and positive pressure operations, replacing multiple specialized check valves. This multi-functionality reduces component variety, simplifies inventory management, and lowers overall manufacturing and maintenance costs.
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 filter device achieves a simpler and more logical flow path structure, improving pressure switching efficiency and reducing costs by using a single valve disc to switch between filters, effectively removing foreign substances from gases under both negative and positive pressures.
Implementation Method 1
a filter for negative pressure, a check valve which allows the flow from the adsorption pad side to the negative pressure source side are connected in series
Implementation Method 2
a shuttle valve is disposed between the first port, and the negative pressure-side and positive pressure-side filters, and the shuttle valve has a valve disc such that when a negative pressure is supplied to the first port, the valve disc opens communication between the first port and the negative pressure-side filter

AI summary
A negative pressure-side flow path having a negative pressure-side filter and a positive pressure-side flow path having a positive pressure-side filter are connected in parallel between a first port and a second port, and a shuttle valve is installed between the negative pressure-side flow path and the positive pressure-side flow path, and the first port, thus when a negative pressure is supplied to the first port, the first port is caused to communicate with the second port through the negative pressure-side flow path, and when a positive pressure is supplied to the first port, the first port is caused to communicate with the second port through the positive pressure-side flow path.
