Solution Overview

Problem

Existing surface cleaning apparatuses, such as hand vacuum cleaners, face challenges in efficiently cleaning particulate matter that accumulates on the outer surfaces of porous members like screens or filters within cyclones, requiring frequent manual intervention for maintenance.

Innovation Solution

A hand vacuum cleaner design featuring a moveable cyclone sidewall and cleaning member that automatically translates into a cleaning position, allowing for enhanced exposure and removal of particulate matter from the porous member without user intervention, utilizing biasing mechanisms like springs to facilitate this process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a porous member is positioned in the cyclone chamber air outlet to separate particulate matter from air, then air treatment effectiveness is improved, but the porous member accumulates particulate matter on its outer surface requiring frequent manual cleaning

Engineering Contradiction:
Improveair treatment effectivenessVSAvoidmaintenance convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The cleaning member is configured to automatically contact and clean the porous member surface as it rotates within the cyclone chamber, enabling self-cleaning functionality without manual intervention. The relative motion between the cleaning member and porous member ensures continuous removal of accumulated particulate matter.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously removes accumulated particulate matter from the porous member surface through the rotating cleaning member, effectively discarding the accumulated debris and recovering the cleaning capacity of the porous member for continued operation.

Inventive Principle:
Principle #34Discarding and recovering

2Device complexity

If manual cleaning of the porous member is required, then device complexity is reduced, but loss of time for maintenance increases

Engineering Contradiction:
Improvecleaning mechanism complexityVSAvoidmaintenance time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The cleaning member rotates continuously within the cyclone chamber, providing ongoing cleaning action that prevents excessive accumulation of particulate matter on the porous member surface, thereby reducing maintenance intervals and time loss.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system performs self-cleaning through the automatic rotation of the cleaning member, eliminating the need for manual disassembly and cleaning operations, thus significantly reducing maintenance time without requiring complex external cleaning systems.

Inventive Principle:
Principle #25Self-service
