Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid circuit devices, particularly those using inverse shuttle valves, face challenges in providing a suitable mechanical configuration for a wide variety of fluids and applications, with issues such as poor reliability due to sliding seals and limited efficiency in handling high pressure differentials and fast switching actions.
Innovation Solution
A fluid circuit device with a pressure balancing valve that links at least two fluid volumes to a third volume, allowing fluid flow between the lower pressure volume and the third volume to maintain pressure equilibrium, which can be manufactured without sliding seals and is suitable for high-speed dynamic applications with tunable flow behavior and high pressure tolerance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inverse shuttle valves are used to balance pressure difference, then pressure equilibrium can be achieved, but reliability deteriorates due to sliding seals
Solution Approach 1:
The patent extracts and eliminates the sliding seal component from the pressure balancing valve design. By using a ball valve mechanism that opens and closes without sliding seals, the invention removes the source of reliability problems while maintaining the pressure balancing function.
Solution Approach 2:
The patent replaces the traditional sliding seal mechanical system with a ball valve mechanism. This substitution eliminates the need for sliding seals and their associated reliability issues, while achieving the same pressure balancing objective through a different mechanical approach.
2Stress or pressure
If traditional valve configurations are used, then manufacturing may be simpler, but pressure tolerance deteriorates in high pressure differential applications
Solution Approach 1:
The patent employs a dynamic ball valve mechanism that responds automatically to pressure differentials. The ball moves to open or close passages based on pressure conditions, enabling the valve to handle high pressure differentials dynamically without requiring complex manufacturing tolerances or precision sliding components.
Solution Approach 2:
The invention changes the operational parameters of the valve by using a ball mechanism that can withstand high pressure differentials. This allows the system to operate effectively in high pressure applications while maintaining ease of manufacture through simpler structural requirements.
3Reliability
If sliding seal configurations are used, then valve operation may be simpler, but reliability deteriorates due to seal wear and failure
Solution Approach 1:
The patent removes sliding seals from the valve operation mechanism, eliminating the component that causes wear and failure. The ball valve operates without sliding seals, maintaining operational simplicity while dramatically improving reliability.
Solution Approach 2:
The invention replaces durable but complex sliding seal mechanisms with a simpler ball valve design that, while potentially having shorter service life in some aspects, eliminates the critical failure point of sliding seals and provides sufficient operational reliability for the application.
4Manufacturing precision
If precision sliding components are required, then manufacturing precision must be high, but ease of manufacture deteriorates
Solution Approach 1:
The patent uses a dynamic ball valve mechanism that does not require precision sliding components. The ball moves freely to open and close passages based on pressure differential, eliminating the need for honed or fitted passages and significantly easing manufacturing requirements.
Solution Approach 2:
The invention replaces precision sliding mechanical components with a ball valve system. This substitution eliminates the need for high manufacturing precision in sliding surfaces, allowing for easier manufacture with standard tolerances.

Implementation Method 1
when there is a pressure difference between the at least one first fluid volume and the at least one second fluid volume, the at least one pressure balancing valve acts to provide a fluid flow path between the at least one third volume and the lower pressure of either the first fluid volume or the second fluid volume
