Laundry Bag Handling with Buffer Station to Reduce Sorting Bottlenecks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry handling systems face inefficiencies due to manual filling of dirty laundry into automatic sorting stations, which creates bottlenecks and requires operators to wait for capacity, leading to suboptimal workflow and capacity limitations.
Innovation Solution
A method and system that involves direct manual filling of dirty laundry into bags at a first handling station, followed by intermediate storage and buffering, allowing for continuous operation and increased capacity through sequential handling and sorting, including automatic transport between stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual filling of dirty laundry into automatic sorting station is used, then the sorting station can process laundry, but the system capacity is limited by the sorting station's receiving capacity creating bottlenecks
Solution Approach 1:
The patent introduces a buffer station that stores laundry bags before they enter the sorting station. Operators can continuously fill bags at the filling station, and the buffer station holds these bags until the sorting station is ready to process them. This preliminary storage action eliminates the need for operators to wait for the sorting station's capacity to be available, thereby resolving the contradiction between processing capacity and operator waiting time.
Solution Approach 2:
The buffer station acts as an intermediary between the filling station and the sorting station. It decouples the filling operation from the sorting operation, allowing them to proceed at different rates without causing bottlenecks or idle time. This intermediary storage mechanism enables continuous operation of the filling station while the sorting station processes laundry at its own pace.
2Device complexity
If the sorting station has limited capacity for receiving laundry, then it can be managed, but it creates a bottleneck for the whole handling system
Solution Approach 1:
The patent adds a temporal dimension to the system by introducing intermediate storage at the buffer station. Instead of only spatial arrangement (filling station -> sorting station), the buffer station adds a time-based storage layer that allows laundry to be held and released according to sorting station availability. This dimensional addition increases overall system capacity without requiring the sorting station itself to be larger or more complex.

AI summary
A method and system for handling and transporting laundry in bags/sacks by means of laundry handling stations and a transport system for transporting the bags/sacks to, through and/or from and/or between the laundry handling stations. The method includes receiving one or more containers of dirty unsorted laundry at a first laundry handling station, emptying the container(s) of dirty unsorted laundry and putting dirty unsorted laundry into the laundry handling station by removing dirty unsorted laundry from each container, and handling the dirty unsorted laundry in the first laundry handling station and then transporting the laundry from the first laundry handling station to a second laundry handling station.
