Solution Overview

Problem

Existing valve devices require significant energy to operate and maintain fluid control, lacking an efficient mechanism for fluid regulation without an electric supply.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If a conventional valve device is used to regulate fluid current, then fluid control is achieved, but significant energy is consumed

Engineering Contradiction:
Improveenergy consumptionVSAvoidfluid control reliability
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The patent replaces conventional mechanical drive mechanisms with an electrodynamic drive system comprising a stator and armature. The armature, when energized, interacts with the stator's magnetic field to generate rotational motion that pivots the connection part, thereby controlling the valve member's position and regulating fluid flow with minimal energy consumption.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The connection part serves multiple functions: it acts as a structural support for the valve member, provides an electrical connection pathway for the armature, and functions as a pivotable linkage for the electrodynamic drive. This multi-functionality reduces the need for separate components, thereby reducing overall system energy requirements while maintaining reliable fluid control.

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

2Adaptability or versatility

If an electric drive device is added to regulate valve position, then fluid channel cross-section can be adjusted, but device complexity increases

Engineering Contradiction:
Improvecross-section adjustment capabilityVSAvoiddrive mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the drive mechanism, connection structure, and electrical connection into a single integrated assembly. The armature is electrically connected to the connection part, which itself is pivotally mounted on the valve housing. This consolidation allows cross-section adjustment capability while minimizing the number of discrete components and simplifying the overall device structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connection part is designed to be pivotably mounted rather than fixed, allowing dynamic adjustment of the valve member's position. This pivotable connection enables the system to achieve variable cross-section regulation through controlled rotation, providing adaptability without requiring complex multi-component mechanisms.

Inventive Principle:
Principle #15Dynamics

3Use of energy by moving object

If the armature is made movable relative to the stator for electrodynamic drive, then energy-efficient operation is achieved, but sealing reliability may be compromised

Engineering Contradiction:
Improveenergy consumptionVSAvoidsealing reliability
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The patent employs a flexible membrane as the valve member that responds to the positional changes of the connection part. This membrane can conform to sealing surfaces and maintain reliable sealing even as the connection part pivots and the armature moves relative to the stator, thus preserving sealing reliability while enabling energy-efficient electrodynamic operation.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The connection part acts as an intermediary between the electrodynamic drive (armature and stator) and the valve member. It translates the armature's relative motion into controlled positioning of the valve member, ensuring that sealing contact is maintained reliably while the armature moves freely relative to the stator for energy-efficient operation.

Inventive Principle:
Principle #24Intermediary (Mediator)
