Trigger-Activated Vented Valve for Pressure Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional valves face issues with pressure reduction in enclosed fluid sources, leading to partial vacuums, and existing solutions like discrete vents are prone to leaks, clogging, and malfunction.
Innovation Solution
A valve design that enables coincident fluidic coupling and uncoupling of fluid delivery and compensation passages with a single trigger, maintaining pressure by allowing simultaneous fluid delivery and compensation flow into the source, eliminating the need for separate vents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If a discrete vent is provided in the fluid source to maintain pressure, then pressure reduction is prevented, but the device complexity increases and reliability decreases due to additional failure points
Solution Approach 1:
The patent combines the vent function with the valve body by integrating a vent passage directly into the valve structure. This eliminates the discrete vent as a separate component, thereby maintaining pressure reliability while reducing device complexity. The vent passage is formed as an integral part of the valve housing, removing potential failure points associated with separate vent components.
Solution Approach 2:
The valve body is designed to perform multiple functions: it serves as both the main valve structure for fluid delivery control and as the housing for the vent passage. This multi-functionality eliminates the need for a separate discrete vent component, thereby improving reliability by reducing the number of parts while maintaining pressure control capability.
2Stress or pressure
If a discrete vent is provided to maintain pressure, then pressure reduction is prevented, but the device complexity increases due to additional parts
Solution Approach 1:
The vent passage is merged with the valve body structure, eliminating the discrete vent as a separate component. This integration reduces the total number of parts and simplifies the device while maintaining the pressure control function. The vent passage is formed directly in the valve housing, removing the need for additional vent components.
3Ease of operation
If a single trigger operates both fluid delivery and compensation passages, then ease of operation improves, but the device complexity increases due to coincident coupling mechanism
Solution Approach 1:
The trigger mechanism is designed to simultaneously control both the fluid delivery passage and the vent passage through a single operational input. This coincident coupling is achieved by integrating the trigger actuation mechanism with both passage controls, allowing one trigger movement to open or close both passages simultaneously, thereby improving ease of operation while the integrated design minimizes additional complexity.
Solution Approach 2:
The single trigger is designed to perform multiple functions: it controls both the fluid delivery passage and the vent passage. This multi-functionality allows a single component to manage both fluid flow and pressure compensation, improving ease of operation by reducing the number of controls needed while the integrated design keeps the complexity manageable.
4Stress or pressure
If discrete vent is used, then pressure compensation is achieved, but harmful factors increase due to potential leaks and clogging
Solution Approach 1:
The vent passage is integrated into the valve body, eliminating the discrete vent component that is prone to leaks and clogging. This integration reduces the number of potential failure points while maintaining pressure compensation functionality. The unified structure minimizes interfaces where leaks could occur and reduces areas where debris could accumulate.
