Multi-Way Valve Assembly With Lockable Reconfigurable Flow Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve systems lack flexibility and are cumbersome due to the need for multiple valves to manage both two-way and three-way fluid flow configurations, which increases size, weight, and cost, particularly in applications where space and weight are critical, such as in aircraft.
Innovation Solution
A multi-way valve assembly with two rotatable valve elements that can be configured to create various flow paths, allowing operation as either a two-way or three-way valve, enabling connection to multiple fluid conduits and allowing for reconfiguration post-installation, utilizing a solenoid for locking and unlocking the valve elements to adjust flow paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple valves are installed to provide both two-way and three-way fluid flow configurations, then the system can achieve the required flow control functionality, but the overall size, weight, and cost of the system increases
Solution Approach 1:
The patent combines multiple valve functions (two-way and three-way flow control) into a single integrated valve body with multiple ports and internal flow paths. This merging eliminates the need for separate two-way and three-way valves, reducing system weight while maintaining configuration flexibility through internal flow path design
Solution Approach 2:
The valve assembly is designed as a universal component that can perform both two-way and three-way fluid flow control functions within a single device. The multi-port configuration and internal flow paths enable the valve to adapt to different flow control requirements without requiring multiple specialized valves, thereby reducing overall system weight
2Adaptability or versatility
If multiple valves are installed to provide both two-way and three-way fluid flow configurations, then the system can achieve the 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 valve body with integrated flow paths, reducing the spatial footprint required for housing multiple separate valves. The consolidated design minimizes the area occupied by valve assemblies while maintaining all necessary flow control capabilities
Solution Approach 2:
The universal valve assembly provides both two-way and three-way flow control in a single compact unit, eliminating the need for multiple valves that would occupy separate spaces. This multi-functional design reduces the overall system footprint while maintaining configuration flexibility
3Adaptability or versatility
If multiple valves are installed to provide both two-way and three-way fluid flow configurations, then the system can achieve the required flow control functionality, but the cost of the system increases
Solution Approach 1:
The patent combines multiple valve functions into a single manufactured unit, reducing the total number of components that need to be sourced, inventoried, and installed. This consolidation lowers material costs, assembly costs, and maintenance costs while providing the same flow control flexibility as multiple separate valves
4Weight of stationary object
If a single valve assembly is used to provide multiple flow configurations, then the system size and weight are reduced, but the valve assembly must be more complex to accommodate multiple flow paths
Solution Approach 1:
The valve body is segmented into multiple functional zones with distinct flow paths and ports, allowing complex multi-way flow control to be achieved through organized internal segmentation rather than a monolithic complex design. This segmentation simplifies the understanding and manufacturing of the valve while maintaining weight reduction benefits
