Solution Overview

Problem

Conventional cyclonic dust-separating apparatuses in vacuum cleaners have poor dust separating efficiency due to a single cyclone unit and require cumbersome removal for dust collection, with potential air leakage issues from unstable installation.

Innovation Solution

A multi cyclone dust-separating apparatus with a body unit and cover unit that can move horizontally, allowing easy coupling and decoupling, and featuring a horizontal movement permitting part to prevent collision and ensure a tight seal, even when unstably positioned.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a multi cyclone dust-separating apparatus is used to improve dust separating efficiency, then dust separating efficiency improves, but the entire apparatus must be removed from the cleaner body to empty the dust-collecting unit, making it troublesome to operate

Engineering Contradiction:
Improvedust separating efficiencyVSAvoidease of emptying dust-collecting unit
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The dust-separating apparatus is divided into a first cyclone unit and a second cyclone unit that can be independently removed from the cleaner body. The second cyclone unit with its dust-collecting unit can be detached separately, allowing users to empty dust without removing the entire apparatus, thus resolving the contradiction between maintaining high dust separating efficiency and improving ease of operation.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If the air inflow part has a vertical surface coupled with a vertical surface of the dust separating apparatus connecting part, then the structure is simple, but air leakage occurs when the apparatus is unstably arranged or wrongly positioned

Engineering Contradiction:
Improvestructural simplicityVSAvoidseal tightness
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The air inflow part is designed with a curved surface that corresponds to a curved surface of the dust separating apparatus connecting part. This curved interface provides better sealing performance compared to vertical surfaces, preventing air leakage when the apparatus is unstably arranged or wrongly positioned, while maintaining reasonable structural simplicity.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Device complexity

If a single cyclone unit is used, then the device complexity is low, but dust separating efficiency is poor

Engineering Contradiction:
Improvenumber of cyclone unitsVSAvoiddust separating efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The dust-separating apparatus incorporates both a first cyclone unit and a second cyclone unit, each capable of separating dust from air. This segmentation into multiple functional units increases dust separating efficiency while keeping each individual unit relatively simple in structure, resolving the contradiction between device complexity and productivity.

Inventive Principle:
Principle #1Segmentation
