Innovation Solution
A depressurizing device comprising a valve base, a flexible member, and a top cover, with a pressure chamber and an outgassing chamber, where the flexible member's depressurizing valve deforms to open or close ports, forming outgassing channels for quick and automatic depressurization, eliminating the need for solenoid valves and allowing for easy replacement and cost-effective production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a solenoid valve is used for depressurization, then the depressurization function is reliable, but the cost increases and replacement becomes expensive
Solution Approach 1:
The patent extracts the depressurization function from the solenoid valve and transfers it to the pump body itself through the integrated valve structure (valve inlet, valve outlet, and depressurization channel). This eliminates the need for separate solenoid valves, reducing cost while maintaining the depressurization function through the built-in mechanical valve mechanism.
Solution Approach 2:
The patent merges the depressurization function with the pump body by integrating the valve structure directly into the pump housing. The valve inlet, valve outlet, and depressurization channel are combined into a single integrated component, eliminating the need for separate solenoid valve assemblies and reducing overall system cost.
2Reliability
If a solenoid valve is used for depressurization, then the depressurization function is reliable, but the device complexity increases
Solution Approach 1:
The patent merges the depressurization function with the pump body by integrating the valve structure directly into the pump housing. The valve inlet, valve outlet, and depressurization channel are combined into a single integrated component, eliminating the need for separate solenoid valve assemblies and reducing overall system complexity.
Solution Approach 2:
The pump body is designed to serve multiple functions: it acts as both the pump housing and the valve body. The integrated structure performs both pumping and depressurization functions, reducing the number of separate components needed and simplifying the overall device architecture.
3Reliability
If a solenoid valve is used for depressurization, then the depressurization function is reliable, but the replacement cost increases when damaged
Solution Approach 1:
The patent merges the depressurization function with the pump body by integrating the valve structure directly into the pump housing. The valve inlet, valve outlet, and depressurization channel are combined into a single integrated component, eliminating the need for separate solenoid valve assemblies and reducing overall system complexity.
4Productivity
If the depressurizing valve deforms quickly, then the depressurization efficiency is faster, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies local quality by creating a concentrated depressurization channel with specific geometric characteristics (narrower width) that enables rapid valve response. The localized channel design focuses the fluid flow and pressure differential, allowing the valve to deform and open quickly without requiring high overall manufacturing precision across the entire pump body.
Solution Approach 2:
The patent changes the geometric parameters of the depressurization channel, specifically making it narrower in width compared to other channels. This parameter modification creates a more efficient pressure differential that accelerates valve deformation and opens the valve faster, improving depressurization speed while maintaining manufacturability.
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 faster depressurization efficiency and reduces production and replacement costs by using flexible member outgassing channels formed through injection molding or thermoforming, enabling quick and low-cost manufacturing and maintenance.
Implementation Method 1
The depressurizing valve is configured to deform caused by the affect of an atmosphere in the pressure chamber, so as to selectively close the first depressurizing port or leave the first depressurizing port to form a second outgassing channel

AI summary
A depressurizing device includes a valve base, a first valve, a flexible member, and a top cover. The valve base has a pressure chamber and an outgassing chamber. Top and bottom surfaces of the pressure chamber have an opening and a first valve port respectively. The first valve is located in the pressure chamber and covers the first valve port. The flexible member is disposed on the valve base and has a depressurizing valve and a first outgassing port, the depressurizing valve covers the opening, and the first outgassing port is communicated with the outgassing chamber. A first outgassing channel is at least formed on the flexible member and communicates the pressure chamber to the outside of the valve base. The top cover is disposed on the flexible member and has a first depressurizing port and a second outgassing port.
