Solution Overview

Problem

Conventional spray nozzles face issues with low assembly performance, dimensional accuracy requirements, and clogging in the self-oscillation type, and limited angle adjustment and spray orifice clogging in the ball jet type, while full-cone nozzles have small vane components and poor side-angle dispersion.

Innovation Solution

A spray nozzle design combining multiple nozzle-divided bodies with integrally formed vane elements for rotating liquid and enhanced assembly, featuring flat surface portions with groove or rib patterns for directional control, and engagement mechanisms for easy assembly, allowing for high precision and flexibility in liquid spray adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a full-cone nozzle with a vane component is used to generate swirling flow, then liquid dispersion over a wide angle is achieved, but assembly performance is low due to the small size of the vane component

Engineering Contradiction:
Improveassembly performanceVSAvoidvane component size
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The nozzle is divided into multiple nozzle-divided bodies that are combined together. Each divided body contains a vane element integrally formed therein, eliminating the need for separate small vane components and improving assembly performance while maintaining the swirling flow generation capability.

Inventive Principle:
Principle #1Segmentation

2Reliability

If a self-oscillation type spray nozzle is used to achieve superior liquid spray performance, then spray performance is improved, but manufacturing complexity increases due to the need for precise water channel design and high dimensional accuracy

Engineering Contradiction:
Improveliquid spray performanceVSAvoiddimensional accuracy of water channel
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The complex water channel is segmented into multiple nozzle-divided bodies. Each divided body contains simplified flow path elements and vane elements that are integrally formed, reducing the dimensional accuracy requirements for each individual component while maintaining overall spray performance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The vane element and flow path element are merged into a single integrally formed component within each nozzle-divided body. This eliminates the need for separate precision-critical components and reduces manufacturing complexity while achieving the desired spray performance.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If a ball jet type spray nozzle with a spherical penetration hole is used to increase angle adjustment freedom, then angle adjustment flexibility is improved, but spray orifice clogging becomes more likely

Engineering Contradiction:
Improveangle adjustment freedomVSAvoidspray orifice clogging resistance
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The spherical penetration hole is segmented into multiple flow path elements distributed across several nozzle-divided bodies. This segmentation prevents clogging by providing multiple alternative flow paths while maintaining angle adjustment flexibility through the modular structure.

Inventive Principle:
Principle #1Segmentation

4Ease of manufacture

If multiple nozzle-divided bodies are combined to improve assembly performance, then assembly performance is improved, but device complexity increases

Engineering Contradiction:
Improveassembly performanceVSAvoidnumber of components
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The nozzle is segmented into a limited number of standardized nozzle-divided bodies that can be easily assembled together. Each divided body is a self-contained module with integral flow path and vane elements, making assembly straightforward while avoiding excessive component proliferation.

Inventive Principle:
Principle #1Segmentation
