Perforated Laundry Drum Queuing for Separate Wash-Dry Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated laundry systems, such as those disclosed in U.S. Pat. No. 6,671,978 and U.S. Publication No. 2007/0169519, are limited in their ability to handle multiple loads with different washing and drying settings, often resulting in clothes sticking to the washer drum or getting snagged during transfer, leading to improper mixing of laundry and undesirable results.
Innovation Solution
An automated laundry system utilizing a plurality of perforated clothes drums that can be queued and processed individually, with a washer/dryer unit and user interface capable of storing and applying distinct washing and drying settings for each load, ensuring separate processing and transfer without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a single washer drum is used to transfer laundry automatically, then automation is improved, but clothes may stick to the drum sides or get snagged, causing improper mixing of laundry
Solution Approach 1:
The patent divides the laundry processing system into multiple separate washer drums (first washer drum, second washer drum) instead of using a single drum. Each drum processes a separate load of laundry independently, preventing clothes from different loads from mixing while maintaining automated operation. The loads are transferred separately through individual transfer mechanisms to the dryer.
2Device complexity
If all loads are washed at the same settings, then device complexity is reduced, but adaptability to different washing requirements is lost
Solution Approach 1:
The patent implements different washing settings for different washer drums (first washer drum with first settings, second washer drum with second settings). Each drum can be configured with specific temperature, cycle type, and other parameters appropriate for its designated load type (e.g., whites vs. colors), allowing customized washing while maintaining automated operation.
3Productivity
If multiple loads are queued in a single drum, then productivity is improved, but manufacturing precision of load separation deteriorates
Solution Approach 1:
The patent uses multiple separate washer drums (first washer drum, second washer drum) to process different loads simultaneously or sequentially. This segmentation maintains precise load separation while improving overall productivity by allowing parallel processing of multiple loads with different settings.

AI summary
An embodiment of the present invention is directed to an automated laundry system. The system includes a number of perforated clothes drums, each of which holds a single load of laundry, and a washer/dryer unit. The washer/dryer unit includes a loading rack for queuing the drums for subsequent washing, a clothes washing component adapted to sequentially receive the drums from the loading rack and wash the respective loads of laundry therein, a clothes drying component adapted to sequentially receive the drums from the clothes washing component and dry the loads of laundry therein, and a holding rack for sequentially receiving the drums from the clothes drying component and holding the drums for a period of time.
