Solution Overview

Problem

Existing multiport valves lack the ability to efficiently change flow configurations between multiple inlet and outlet ports, failing to provide selective and secure fluid stream direction in multiple positions without mixing.

Innovation Solution

A five-port valve design with a rotatable stemshell and channels that allow specific inlet ports to connect to specific outlet ports through various angular positions, preventing fluid mixing by using bores and channels to direct flow paths while allowing selective operation by actuators.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a multiport valve is designed to provide multiple flow configurations, then the valve's versatility and adaptability improve, but the device complexity and difficulty of achieving precise flow path control increase

Engineering Contradiction:
Improveflow configuration versatilityVSAvoidvalve structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The valve body is divided into separate port sections with distinct inlet ports (2, 3, 5) and outlet ports (1, 4), allowing independent control of multiple flow paths. The internal passages are segmented to create separate routing options for different fluid streams, enabling four distinct flow configurations without requiring a single complex mixing chamber.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The valve utilizes three-dimensional spatial arrangement of ports and internal passages to achieve multiple flow configurations. By positioning ports at different locations on the valve body and creating three-dimensional routing paths within the valve, the design enables selective connection of inlet ports to outlet ports through vertical and horizontal passage variations, achieving versatility without increasing operational complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If the valve provides multiple flow paths simultaneously, then the productivity and functionality improve, but the risk of fluid stream mixing increases

Engineering Contradiction:
Improveflow path efficiencyVSAvoidfluid stream mixing
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The internal passage system is segmented into separate, physically isolated routing paths that connect specific inlet ports to specific outlet ports. Each flow configuration uses dedicated passages that prevent cross-contamination between fluid streams, ensuring that multiple flow paths operate simultaneously without mixing while maintaining high productivity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The valve body acts as an intermediary structure with defined internal passages that mediate between inlet ports and outlet ports. These passages serve as controlled intermediaries that guide fluid streams along predetermined paths, preventing direct mixing while enabling efficient flow distribution across multiple ports simultaneously.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If the valve uses a rotatable stemshell mechanism, then the ease of operation and flow path selection improve, but the manufacturing precision requirements increase

Engineering Contradiction:
Improveflow path selection easeVSAvoidstemshell angular positioning
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The stemshell is designed as a rotatable component that can dynamically change angular position to select between four distinct flow configurations. This dynamic mechanism allows operators to easily switch between flow paths by rotating the stemshell to predetermined angular positions, where each position aligns internal passages with specific port combinations, providing ease of operation while maintaining reliable flow control.

Inventive Principle:
Principle #15Dynamics

AI summary

A multiport valve has a plurality of inlets and outlets with selected positions to selectively direct fluid differently through the valve based on the position of the valve. A cylindrical exterior stemshell rotates internal to a housing to position channels and/or bores to provide the desired flow paths. Some flow paths are channels which extend linearly from one port to another, whether formed into an exterior surface, parallel to an axis of rotation of the stemshell, or pass from an inlet to an outlet in the exterior surface of the stemshell, preferably separated from flow from flow to an internal passage, which is preferably colinear with the axis of rotation, for at least some embodiments.
