Solution Overview

Problem

Cyclone dust collectors in cleaners face efficiency reduction and clogging due to dust accumulation on their inner walls, making it difficult to effectively separate dust from the air and requiring complex cleaning processes.

Innovation Solution

Incorporating a rotating cleaning member with a deformable material that contacts the inner wall of the cyclone, potentially coupled with a brush or auxiliary cleaning member, to remove dust accumulation and prevent clogging, while being integrated with a detachable structure for easy maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a cyclone dust collector is used to separate dust from air, then dust filtering efficiency is improved and it becomes semipermanently usable, but dust accumulates on the inner wall causing clogging and efficiency reduction

Engineering Contradiction:
Improvedust filtering efficiencyVSAvoiddust accumulation on inner wall
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The cyclone dust collector is designed to automatically remove dust accumulated on its inner wall using the suction force generated by its own driver. The suction force creates a cleaning flow that moves along the inner wall, preventing dust accumulation and clogging without requiring external intervention or additional cleaning mechanisms.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The dust accumulation problem is converted into a benefit by utilizing the suction force that causes dust to accumulate in the first place. The same suction force is directed to create a cleaning flow along the inner wall, transforming the harmful accumulation effect into a useful self-cleaning mechanism.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

2Productivity

If the cyclone dust collector operates continuously, then productivity is improved, but dust accumulation on the inner wall increases causing clogging

Engineering Contradiction:
Improvecontinuous operation capabilityVSAvoiddust filtering efficiency
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The self-cleaning function operates continuously during the entire operation of the cyclone dust collector. The suction force continuously generates a cleaning flow along the inner wall, ensuring that dust is removed as it accumulates, allowing the device to maintain high filtering efficiency throughout continuous operation without periodic shutdowns for manual cleaning.

Inventive Principle:
Principle #20Continuity of useful action

3Ease of manufacture

If the cyclone dust collector is designed with a simple structure, then ease of manufacture is improved, but it becomes difficult to remove dust from the inner wall

Engineering Contradiction:
Improvestructural simplicityVSAvoiddust removal difficulty
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

Instead of designing complex manual cleaning mechanisms or easily removable inner walls, the cyclone dust collector uses its own operational suction force to automatically clean the inner wall. This self-service approach maintains structural simplicity while effectively solving the dust removal problem.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The suction force, which is essential for dust separation and would naturally cause dust to accumulate on the inner wall, is repurposed to create a cleaning flow that removes dust. This converts a potentially harmful side effect into a beneficial self-cleaning function without adding structural complexity.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)
