Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve systems lack flexibility and are bulky, heavy, and costly, making them unsuitable for applications where space and weight are critical, such as in aircraft, as they require multiple valves for different fluid flow configurations and do not allow for easy addition of new fluid supplies or applications post-installation.
Innovation Solution
A multi-way valve assembly with two rotatable valve elements and a locking mechanism that allows for various flow path configurations, enabling operation as both two-way and three-way valves, with the ability to connect multiple fluid conduits and reconfigure after installation, using a solenoid to control the relative rotation of the valve elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate valves are installed to provide different fluid flow configurations, then the system can achieve required flow control functionality, but the overall size, weight, and cost of the system increases
Solution Approach 1:
The patent combines multiple valve functions into a single integrated valve assembly. The housing contains multiple ports (first port, second port, third port, fourth port) that can be connected through different flow paths by rotating the ball element. This merging of multiple valve functions into one assembly reduces the overall number of separate valves needed, thereby decreasing total weight while maintaining versatility in fluid flow configurations.
Solution Approach 2:
The valve assembly is designed as a universal multi-functional unit where a single ball element with multiple flow channels can direct fluid flow between different port combinations. By rotating the ball element to different positions, the same valve assembly can provide various flow configurations (e.g., first port to second port, first port to third port, etc.), eliminating the need for multiple specialized valves and reducing overall system weight.
2Adaptability or versatility
If multiple separate valves are installed to provide different fluid flow configurations, then the system can achieve required flow control functionality, but the overall size of the system increases
Solution Approach 1:
The patent merges multiple valve functions into a single compact housing that contains all necessary ports and flow paths. The integrated design allows the valve assembly to occupy a smaller footprint compared to multiple separate valves, while still providing the ability to control fluid flow between different port combinations through rotation of the ball element.
Solution Approach 2:
The universal valve assembly design allows one compact unit to perform multiple flow control functions. The ball element with its multiple flow channels can be rotated to connect different port pairs, providing various flow configurations within a single small footprint, thereby reducing the overall area required compared to installing multiple separate valves.
3Adaptability or versatility
If traditional valve systems are used, then the system can provide basic flow control, but the system lacks flexibility for adding additional fluid supplies or applications after installation
Solution Approach 1:
The valve assembly incorporates a dynamic ball element that can be rotated to different positions to change flow paths. This dynamic capability allows the valve to be reconfigured after installation by simply rotating the ball element to different orientations, enabling connection of additional fluid supplies or applications without requiring complex mechanical reconfiguration or additional components.
Solution Approach 2:
The universal design of the valve assembly with multiple ports and a multi-channel ball element provides inherent flexibility for post-installation reconfiguration. The same valve structure can support various flow configurations and can be adapted to connect different fluid supplies or applications by rotating the ball element, without increasing structural complexity.
4Adaptability or versatility
If multiple valves are installed to provide different fluid flow configurations, then the system can achieve required flow control, but the cost of the system increases
Solution Approach 1:
The patent merges the functionality of multiple separate valves into a single integrated valve assembly. Instead of installing multiple individual valves to achieve different flow configurations, the unified assembly provides all necessary flow paths within one unit, thereby reducing the quantity of valves from multiple to one and reducing overall system cost.
Solution Approach 2:
The universal valve assembly provides multi-functionality that replaces multiple specialized valves. A single ball element with multiple flow channels can perform the functions of several separate valves, reducing the number of components needed and thereby reducing the total cost of the valve system while maintaining adaptability for different fluid flow configurations.

AI summary
A multi-way valve assembly includes a valve housing having a plurality of fluid ports, a first valve member having one or more first flow channels defined therethrough and a first shaft, rotation of which causes rotation of the first valve member relative to the housing, the first valve member defining a cavity, and a second valve member arranged within the cavity of the first valve member and having one or more second flow channels defined therethrough and a second shaft. Rotation of the second shaft causes rotation of the second valve member relative to the housing. The assembly also includes a locking mechanism configured to, in a locked position, cause the second valve member to rotate with the first valve member relative to the housing and, in an unlocked position, to permit the second valve member to rotate relative to the first valve member and the housing.
