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

VSEngineering 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

Engineering Contradiction:
Improveflow control configuration flexibilityVSAvoidsystem weight
Core Design Contradiction:
Adaptability or versatilityVSWeight of stationary object

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

Inventive Principle:
Principle #5Merging (Combining)

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improveflow control configuration flexibilityVSAvoidsystem footprint
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

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

Inventive Principle:
Principle #5Merging (Combining)

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improveflow control configuration flexibilityVSAvoidsystem cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

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

Inventive Principle:
Principle #5Merging (Combining)

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

Engineering Contradiction:
Improvesystem weightVSAvoidvalve assembly complexity
Core Design Contradiction:
Weight of stationary objectVSDevice complexity

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

Inventive Principle:
Principle #1Segmentation

AI summary

A multi-way valve assembly comprising: a valve housing (3) having a plurality of fluid ports (30); a first valve member (14) having one or more first flow channels defined therethrough and a first shaft (11), rotation of which causes rotation of the first valve member relative to the housing, the first valve member defining a cavity; a second valve member (21) arranged within the cavity of the first valve member and having one or more second flow channels defined therethrough and a second shaft (7), rotation of which causes rotation of the second valve member relative to the housing; and a locking mechanism (23, 24, 26, 27) 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.
