Clothing Hanger Sorting with 1 MHz Data Reading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for sorting clothing on transport hangers are inefficient due to the need for large distances between hangers to read data, limiting sorting capacity and quality.
Innovation Solution
A method and device that operate a reading device at a frequency of at least 1 MHz, allowing for rapid data reading and sorting of closely spaced transport hangers, with an antenna that can read data wirelessly and move hangers at high speeds, reducing the distance between them to increase sorting performance without sacrificing quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transport hangers are spaced at large distances to enable data reading, then data reading reliability is improved, but sorting performance deteriorates
Solution Approach 1:
The patent changes the operating frequency parameter of the reading device from conventional low frequencies to at least 1 MHz. This parameter change enables the reading device to read data from transport hangers at high speeds even when hangers are closely spaced, thereby maintaining data reading reliability while improving sorting performance by allowing higher transport speeds and closer hanger spacing.
2Productivity
If transport speed is increased to improve sorting performance, then productivity is improved, but data reading accuracy deteriorates
Solution Approach 1:
The patent employs a reading device operating at a frequency of at least 1 MHz, which enables the system to read data accurately even at high transport speeds of up to 300 hangers per minute. The high-frequency operation allows the reading device to complete data acquisition quickly, maintaining accuracy despite the reduced interaction time caused by higher speeds.
3Productivity
If distance between transport hangers is reduced to increase sorting capacity, then productivity is improved, but data reading reliability deteriorates
Solution Approach 1:
By operating the reading device at a frequency of at least 1 MHz, the patent enables reliable data reading even when transport hangers are spaced only 50-150 mm apart. The high-frequency operation allows sufficient data to be read from each hanger within the reduced time window created by closer spacing, thereby maintaining reliability while doubling sorting capacity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach significantly increases sorting capacity, allowing up to twice as many hangers to be sorted per minute while maintaining high accuracy, and enables continuous uninterrupted transport, enhancing overall sorting performance and efficiency.

AI summary
The method involves transporting a set of transporting hangers (11) along a rail system (10), and reading relevant data of pieces of clothes by a reading device (20) from a data storage of the respective transporting hanger or the piece of clothes hung on the transporting hanger. The pieces of clothes are sorted depending on the data, and the reading device is operated with a frequency of 1 mega Hertz (MHZ). The transporting hanger is transported past to the reading device with 50 millimeter to 150 millimeter distance. An independent claim is also included for a device for sorting pieces of clothes hanging on a transporting hanger.
