Solution Overview

Problem

Cyclone preliminary separators in the craft area are not easily transportable and storable due to their design, which hinders their handling and usage efficiency.

Innovation Solution

A box-shaped cyclone preliminary separator with a vertical tensile-resistant coupling system, allowing for stacking and easy handling, along with a particle ascension container designed for efficient stacking and transport, and an adapter frame for stable vertical stacking with a suction device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional cyclone pre-separator is used, then particle separation function is provided, but transportability and stowability are poor

Engineering Contradiction:
ImprovetransportabilityVSAvoidhousing shape
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The patent applies the opposite principle by using a box-shaped (cuboid) housing instead of a curved or conical shape. The housing comprises vertical side walls and a horizontal top surface, creating a rectangular prism geometry that enables efficient stacking and storage in trade environments while maintaining the cyclone separation function.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Reliability

If a conventional coupling system is used, then connection with particle collection container is achieved, but vertical tensile resistance is insufficient

Engineering Contradiction:
Improvecoupling stabilityVSAvoidcoupling mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The coupling system is segmented into distinct upper and lower coupling means with specific geometric features. The lower coupling means include downwardly projecting engagement structures on the housing, while the upper coupling means have corresponding upwardly projecting structures on the particle collection container, creating a modular and reliable connection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling mechanism uses asymmetric geometric features including downwardly and upwardly projecting engagement structures that interlock in a specific orientation. This asymmetric design provides inherent vertical tensile resistance while maintaining ease of assembly and disassembly.

Inventive Principle:
Principle #4Asymmetry

3Adaptability or versatility

If stackable system compatibility is added, then storage efficiency improves, but device complexity increases

Engineering Contradiction:
Improvestacking compatibilityVSAvoidhousing design
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The box-shaped housing serves multiple functions: it maintains the cyclone separation chamber, provides structural support, enables stacking compatibility with standard trade equipment, and facilitates transport. The universal cuboid geometry allows integration into various stacking systems without requiring additional components.

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