Laundry Capture Point Detection for Single-Item Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for capturing laundry items from a pile are inefficient, often grabbing multiple items or failing to capture any, leading to incorrect treatment and reduced performance due to the reliance on unfavorable grabbing points.
Innovation Solution
A method that uses topography analysis, preferably through 3D imaging or laser scanning, to determine optimal points on the laundry for capture by a suction or grabber device, ensuring precise and controlled capture and separation of individual items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional grabbing methods are used to capture laundry items from a pile, then the capturing process is simple and quick, but multiple items are grabbed simultaneously or no item is captured, leading to unreliable separation
Solution Approach 1:
The system performs preliminary actions by determining the topography of the laundry item and identifying suitable capture points before the actual capturing operation. This advance preparation ensures that when the grabbing means operates, it targets the correct location, guaranteeing reliable capture of a single item rather than multiple items or failure to capture.
Solution Approach 2:
The patent replaces simple mechanical grabbing with a system that uses optical or imaging technology to detect topography and identify capture points. This substitution of mechanical intuition with sensing and information processing enables precise targeting of capture points, significantly improving reliability while managing complexity through automation.
2Productivity
If conventional grabbing methods are used without topography analysis, then the system is simple to operate, but capturing efficiency drops due to incorrect capture points and repeated failures
Solution Approach 1:
The system performs preliminary topography determination and capture point identification before the actual capturing operation. This advance analysis of the laundry item's surface characteristics enables the grabbing means to target optimal locations, ensuring successful capture on the first attempt and maximizing productivity without requiring complex repeated operations.
Solution Approach 2:
The patent introduces an intermediary system between the grabbing means and the laundry item - specifically, the topography determination and capture point identification system. This intermediary layer processes information about the laundry's surface characteristics and translates it into precise positioning instructions, bridging the gap between simple grabbing mechanics and intelligent capture.
3Reliability
If the capturing means targets arbitrary points on laundry items, then the operation is straightforward, but capture fails when the targeted point is unfavorable
Solution Approach 1:
The patent replaces arbitrary mechanical targeting with a sensing-based system that detects topography and identifies suitable capture points. By using optical or imaging technology to analyze the laundry item's surface characteristics, the system automatically determines optimal capture locations, eliminating the need for manual judgment and ensuring high success rates.
Solution Approach 2:
The system enables the laundry item to essentially select its own capture point by analyzing its own topography. The topography determination system identifies features of the specific item (folds, edges, surface characteristics) and automatically determines the most suitable capture location for that particular item, allowing each item to be handled according to its unique characteristics.

Function Achieved in This Case
Ensures reliable and efficient capture of individual laundry items, improving processing efficiency by identifying suitable points for grabbing, such as edges or corners, and orienting the capturing means accordingly, reducing errors and increasing throughput.

AI summary
A method for capturing an item of laundry in a reliable and efficient manner. Washed items of laundry usually leave a washing machine intertwined with one another as a pile of laundry. Before the items of laundry that come out of a washing machine in this way are subjected to further treatment steps, for example mangling or sorting, they have to be separated. In the method, the topography of the item of laundry is ascertained and at least one point of the item of laundry at which the item of laundry is intended to be captured and/or preferably can be captured by a capturing means is determined on the basis of this topography. The item of laundry is captured by the capturing means by specific control of the capturing means at this point.
