Agitator assembly with scrub brush for a fabric treating appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fabric treating appliances, such as washing machines, lack an efficient mechanism for pretreating stains and dispensing wash additives directly during the wash cycle, relying on separate dispensing cups and indirect methods.
Innovation Solution
An agitator assembly with a removable cap, scrub brush, and centrifugally actuated dispensing cup system that allows for direct application of treatment chemistry to fabrics and efficient dispensing of wash additives during the wash cycle, featuring a scrubbing surface and graduated dosage gauge for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate dispensing cup system is used for wash additives, then the dispensing function is achieved, but the device complexity increases and user convenience decreases
Solution Approach 1:
The patent combines the dispensing cup, dispensing mechanism, and cap into a single integrated assembly that attaches to the agitator. This merging of previously separate components (dispensing cup, cap, and agitator system) simplifies the overall device structure and improves user convenience by providing a unified, easier-to-operate system for adding wash additives.
2Productivity
If indirect water-based treatment is used, then the washing process is simplified, but stain pretreatment effectiveness is reduced
Solution Approach 1:
The patent enables preliminary stain treatment by allowing users to apply treatment chemistry directly to stains on fabric items before the wash cycle begins. The cap with its open top and scrub brush provides a mechanism for pre-application of chemicals and mechanical scrubbing action, preparing the fabric for the subsequent wash cycle and improving overall cleaning efficiency.
Solution Approach 2:
The cap serves as an intermediary tool that bridges the user and the fabric item during pretreatment. It provides a platform for applying treatment chemistry directly to the fabric and incorporates a scrub brush for mechanical action, facilitating the pretreatment process without requiring separate tools or complex procedures.
3Adaptability or versatility
If a removable cap with scrub brush is added, then stain pretreatment capability is improved, but the device complexity increases
Solution Approach 1:
The cap is designed to perform multiple functions: it serves as a cover for the dispensing cup, provides an open top for direct application of treatment chemistry to fabric, incorporates a scrub brush for mechanical scrubbing action, and can be removed and reattached as needed. This multi-functionality increases adaptability for different treatment needs while avoiding the need for entirely separate devices.
