Solution Overview

Problem

Existing fluidic control and regulation technologies, such as valves, are often complex, bulky, and designed for specific types of fluids, lacking versatility and ease of use for multiple fluid types, and they often have moving parts in direct contact with the fluid, which complicates their construction and maintenance.

Innovation Solution

A compact valve module with an integrated micro-servomotor actuator that controls fluid flow in multiple lines using a rotary cam mechanism, allowing for simultaneous regulation of at least two fluid circulation lines with a simple, segmented, and easy-to-clean design, featuring elastically deformable duct portions and a U-shaped support body for efficient fluid control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If conventional valve designs are used, then fluid control function is achieved, but device complexity and bulkiness increase

Engineering Contradiction:
Improvevalve construction complexityVSAvoidfluid control reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The valve device is segmented into distinct functional components: a body housing, a movable closure member, and a drive mechanism. This segmentation allows each component to be optimized independently while maintaining overall system reliability through modular assembly and easier maintenance access.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The valve device incorporates a multi-functional design where the closure member serves both as a flow control element and as a mechanical linkage for the drive mechanism. The body housing integrates multiple functions including structural support, fluid distribution, and actuator mounting, thereby reducing overall device complexity.

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

2Adaptability or versatility

If valves are designed for specific fluid types, then performance for that fluid is optimized, but adaptability to other fluid types decreases

Engineering Contradiction:
Improvefluid type versatilityVSAvoidfluid-specific optimization precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The valve is designed with universal compatibility features including chemically resistant materials suitable for multiple fluid types, standardized connection interfaces, and a closure member geometry that effectively controls various fluid viscosities and densities. This allows a single design to maintain adequate performance across diverse fluid applications.

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

Solution Approach 2:

The valve system allows for parameter adjustments including closure member position, spring tension, and actuator force to optimize performance for different fluid types. These adjustable parameters enable the same physical device to adapt to varying fluid properties while maintaining manufacturing precision through standardized components.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If moving parts are placed in direct contact with fluid, then flow control effectiveness is improved, but contamination risk and maintenance complexity increase

Engineering Contradiction:
Improveflow control effectivenessVSAvoidfluid contamination risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The drive mechanism is extracted and positioned outside the fluid pathway, connected to the closure member through a sealed transmission mechanism. This extraction eliminates direct contact between the actuator and fluid, preventing contamination while maintaining flow control effectiveness through the sealed linkage system.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

A sealed intermediate mechanism serves as a mediator between the external actuator and the internal closure member. This intermediary component transmits mechanical motion while maintaining fluid isolation, allowing effective flow control without direct contact between moving parts and fluid, thereby reducing contamination risk.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Volume of moving object

If a compact valve design is implemented, then space efficiency is improved, but ease of assembly and maintenance may deteriorate

Engineering Contradiction:
Improvevalve module volumeVSAvoidassembly ease
Core Design Contradiction:
Volume of moving objectVSEase of manufacture

Solution Approach 1:

The compact valve module is segmented into standardized sub-components that can be pre-assembled and tested independently before final integration. This segmentation enables compact overall dimensions while maintaining assembly ease through modular construction, allowing quick replacement and maintenance of individual components without disassembling the entire device.

Inventive Principle:
Principle #1Segmentation
