Solution Overview

Problem

Existing water valves are complex in structure and difficult to control due to the need for dual waterways and mechanical switching mechanisms, which are cumbersome and inefficient, especially when solenoid valves fail.

Innovation Solution

An outlet valve design featuring a valve body with a solenoid valve and manual operating member, incorporating a waterproof membrane and plugs to control water flow without requiring mechanical action for switching, simplifying the structure and control process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a double waterway switching mode is used with solenoid valve and mechanical valve, then the valve can continue to function when one control mechanism fails, but the structure becomes complex requiring two waterways and a special switching valve core

Engineering Contradiction:
Improvevalve functionalityVSAvoidstructure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the solenoid valve and manual operating member into a single integrated valve body structure, eliminating the need for separate switching mechanisms. The first and second waterways are merged into one unified waterway system that can be controlled by either the solenoid valve or manual operating member, reducing structural complexity while maintaining redundancy for reliability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The valve body is designed with multi-functionality, allowing the same waterway structure to be controlled by both automatic (solenoid valve) and manual operating members. This universal design enables the valve to function reliably through multiple control paths without requiring duplicate waterway systems or specialized switching components.

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

2Ease of operation

If a special switching valve core is arranged between two waterways, then switching control is achieved, but the structure becomes more complex

Engineering Contradiction:
Improveswitching controlVSAvoidstructure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the special switching valve core from the design. Instead of using a complex switching mechanism, the invention directly connects the solenoid valve and manual operating member to the waterway system, allowing each control mechanism to independently manage water flow without requiring an intermediate switching component.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical switching valve core with a simplified control architecture where the solenoid valve (electromagnetic actuation) and manual operating member directly control water flow through the unified waterway. This substitution eliminates complex mechanical switching while maintaining effective control functionality.

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