Washer Scrubbing Tool Seat for Manual Stain Pretreatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fabric treating appliances often fail to completely remove certain stains during wash cycles, prompting users to manually address these stains before washing.
Innovation Solution
A fabric treating appliance with a rotatable basket and a scrubbing tool seat that allows for manual stain pretreatment using a removable scrubbing tool, which can be used to apply and dispense cleaning agents directly to stains, enhancing stain removal capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If preprogrammed wash cycles are used, then the washing machine operates automatically and conveniently, but certain stubborn stains cannot be fully removed
Solution Approach 1:
The scrubbing tool enables preliminary manual stain treatment before the main wash cycle. Users can apply cleaning agents and mechanically scrub stains beforehand, preparing the fabric for more effective machine washing. This preliminary action addresses stains that automated cycles alone cannot handle.
Solution Approach 2:
The scrubbing tool acts as an intermediary device between the user and the fabric. It provides a mechanical means (scrubbing bristles) and chemical means (cleaning agent application) to treat stains manually, bridging the gap between automated washing limitations and effective stain removal.
2Reliability
If manual stain treatment is performed before washing, then stain removal effectiveness improves, but user time and effort increase
Solution Approach 1:
The scrubbing tool is designed for easy self-service operation. The removable brush head and simple structure allow users to quickly apply cleaning agents and scrub stains without requiring complex procedures or extensive time investment. The tool makes manual pretreatment an efficient, user-friendly process.
3Reliability
If a scrubbing tool is added to the washing machine, then stain removal capability is enhanced, but device complexity increases
Solution Approach 1:
The scrubbing tool is segmented into separate components: a removable brush head and a handle. This segmentation allows the tool to be easily attached and detached from the washing machine, and the brush head to be replaced or cleaned independently. The modular design adds functionality without permanently complicating the washing machine structure.
Solution Approach 2:
The scrubbing tool serves multiple functions: applying cleaning agents, mechanical scrubbing, and can be used on various fabric types and stain locations. This multi-functionality justifies the added component by providing versatile stain treatment capabilities within a single integrated tool.

AI summary
A fabric treating appliance having a cabinet with an interior and having a top wall defining an access opening. A cover is provided that is movable relative to the cabinet between an open position and a closed position to selectively close the access opening. A shroud extends between the cabinet and the tub. A scrubbing tool seat is located in one of the top wall and the shroud and a scrubbing tool is removably disposed in a scrubbing tool seat.
