Single-Motor Multifunctional Valve Assembly for Lower Weight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multifunctional valve assemblies are heavy and complex due to the use of individual motors for each valve, which increases weight and operational complexity.
Innovation Solution
A lightweight multifunctional valve assembly is designed with a single motor operating both a first portion with 3-way valve functionality for controlling a first fluid and a second portion with 3-way valve functionality for controlling a second fluid, incorporating an integrated and replaceable filter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual motors are used for each valve in multifunctional valve assemblies, then each valve can be independently controlled, but the weight and operational complexity of the system increases
Solution Approach 1:
The patent combines multiple valve functions into a single integrated valve body with multiple ports and internal passages. This single valve replaces what would traditionally require multiple separate valves and motors, thereby reducing overall system weight while maintaining the ability to control multiple fluid flows independently through the shared valve mechanism
Solution Approach 2:
The invention creates a multifunctional valve assembly where a single valve body performs multiple functions by directing different fluid flows through various combinations of ports. The valve can simultaneously or independently control multiple fluid paths, eliminating the need for separate dedicated valves for each function and reducing total system weight
2Ease of operation
If individual motors are used for each valve, then precise control is achieved, but the device complexity increases
Solution Approach 1:
The patent merges multiple valve functions into a single integrated valve body with a unified control mechanism. This consolidation reduces the number of separate motor-valve assemblies from multiple to one, thereby reducing device complexity while maintaining precise control over multiple fluid flows through the shared valve mechanism
Solution Approach 2:
The invention designs a universal valve body that can perform multiple valve functions simultaneously or sequentially. By creating a single multifunctional component rather than multiple single-function components, the system achieves precise control over multiple fluid paths while reducing overall device complexity
3Reliability
If traditional valve assemblies are used, then reliable fluid control is achieved, but the weight increases
Solution Approach 1:
The patent combines multiple fluid control functions into a single valve body, reducing the total weight of the valve assembly while maintaining reliable fluid control. The integrated design ensures proper sealing and flow control for multiple fluid paths without requiring multiple separate heavy valve assemblies
