Solution Overview

Problem

Existing valve actuating devices in water filtration systems are complex, difficult to operate, and prone to secondary pollution due to their intricate structure, which complicates the separation of the valve seat and body, hindering the smooth flow of liquids.

Innovation Solution

A valve actuating device with a simple structure featuring a body and suspension device, such as a claw with a protrusion and connecting arm, that penetrates through holes in the valve seat to separate the valve body from the seat, allowing liquid flow and easy operation by hand, without additional fixing, and can be made of materials like PP, PE, or nylon.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a spiral axial movement mechanism is used to actuate the valve, then the valve can be opened and closed, but the structure becomes complicated and operation becomes difficult

Engineering Contradiction:
Improvevalve operationVSAvoidactuating mechanism structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the complex spiral axial movement mechanism and replaces it with a simple lifting motion. The valve body is separated from the valve seat through vertical displacement only, removing unnecessary rotational and axial components while achieving the same valve opening function.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using a spiral motion that combines rotation and axial movement, the patent inverts the approach by using pure vertical lifting motion. The valve body is lifted straight up from the valve seat through the through-hole, achieving valve opening without any rotational component.

Inventive Principle:
Principle #13The other way round (Inversion)

2Object-affected harmful factors

If the valve structure is complex, then the valve can be sealed properly, but it causes secondary pollution and is difficult to operate from inside the liquid container

Engineering Contradiction:
Improvesecondary pollutionVSAvoidvalve opening operation
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent segments the valve body from the valve seat, allowing the valve body to be completely separated and lifted through the through-hole. This segmentation enables simple external operation without complex internal mechanisms, reducing the risk of secondary pollution from complicated internal structures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the operational dimension from internal spiral motion to external vertical lifting. By moving the valve body vertically through the through-hole from the outside, the operation becomes simpler and less prone to causing secondary pollution compared to internal mechanisms.

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

3Productivity

If the valve body is tightly sealed to the valve seat, then the valve closes properly, but it hinders smooth liquid flow when open

Engineering Contradiction:
Improveliquid flow smoothnessVSAvoidvalve sealing
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent designs the valve body with a lifting action that preliminarily separates it from the valve seat through the through-hole before full opening. This preliminary separation ensures smooth liquid flow path is established early, while the valve body maintains sealing capability when closed through proper positioning.

Inventive Principle:
Principle #10Preliminary action
