Solution Overview

Problem

Existing cleaners face issues with usability, maintenance, and power consumption due to foreign substances like hair and thread wrapping around the drum brush, leading to inefficiencies and increased energy use.

Innovation Solution

A cleaner design featuring a scraper with inclined portions and recessed areas that guide foreign substances away from the drum brush, combined with a housing structure that includes guide protrusions to prevent entanglement and facilitate easy removal of substances.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a drum brush is used to sweep the cleaning surface, then foreign substances are efficiently induced into the suction portion, but foreign substances wrap around the drum brush

Engineering Contradiction:

Improvecleaning efficiencyVSAvoidforeign substance wrapping

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The scraper extracts foreign substances wrapped around the drum brush by guiding them away from the brush surface through its inclined portions, separating the harmful wrapped substances from the cleaning mechanism

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The scraper acts as an intermediary component between the drum brush and the suction portion, facilitating the removal of wrapped foreign substances before they can cause harm to the cleaning process

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If foreign substances wrap around the drum brush, then cleaning performance deteriorates, but maintenance complexity increases

Engineering Contradiction:

Improvecleaning performanceVSAvoidmaintenance complexity

Core Design Contradiction:

ProductivityVSEase of repair

Solution Approach 1:

The scraper enables self-service maintenance by automatically guiding wrapped foreign substances away from the drum brush during operation, allowing the brush to self-clean without requiring user intervention for maintenance

Inventive Principle:

Principle #25Self-service

3Productivity

If foreign substances wrap around the drum brush, then cleaning effectiveness is maintained, but power consumption increases

Engineering Contradiction:

Improvecleaning effectivenessVSAvoidpower consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The scraper extracts wrapped foreign substances from the drum brush surface, preventing the increased power consumption that would result from the brush struggling to rotate with wrapped debris

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A cleaner may include: a housing including a suction port; a drum brush in the housing and that is rotatable; and a scraper including: an edge including: a first inclined portion inclined along a first direction, a second inclined portion inclined along a second direction opposite to the first direction, and a recessed portion at least partially formed by the first inclined portion and the second inclined portion, wherein at least a portion of the scraper is configured to contact the drum brush, and the first inclined portion and the second inclined portion are configured so that, with rotation of the drum brush, a foreign substance attached to the drum brush is moved in the second direction.
