Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current washing methods for textile laundry items are inefficient, requiring extensive time and mechanical stress, which leads to wear and tear on the items, and involve significant resource consumption for testing various detergent formulations.
Innovation Solution
A method utilizing dual asymmetric centrifugation to accelerate the washing process by rotating a washing container about two axes, one outside and one through the container, to enhance diffusion of the washing fluid, reducing washing time to under a minute without mechanical movement of the items, and a device designed for this purpose with multiple washing cells and temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional washing methods with mechanical movement of laundry items are used, then washing effectiveness is achieved, but washing time is extended and mechanical wear on items increases
Solution Approach 1:
The patent replaces traditional mechanical washing actions (agitation, tumbling, rubbing) with a centrifugal field generated by rotating the washing container at high speed. The centrifugal force drives fluid circulation and diffusion through the laundry items without requiring mechanical movement of the items themselves, thereby reducing washing time and mechanical wear simultaneously
Solution Approach 2:
The patent changes the physical parameters of the washing process by introducing high-speed rotation (centrifugal acceleration) to alter fluid dynamics and diffusion rates. By controlling rotation speed and fluid flow parameters, the system achieves effective washing in reduced time without excessive mechanical stress on the laundry items
2Reliability
If numerous test washings are conducted to evaluate different detergent formulations, then comprehensive testing is achieved, but time consumption and resource usage increase significantly
Solution Approach 1:
The washing container is divided into multiple independent washing cells that can operate simultaneously. This allows parallel testing of multiple detergent formulations under different conditions, significantly reducing the total time required for comprehensive evaluation while maintaining reliable results through controlled individual cell environments
Solution Approach 2:
The washing device is designed as a universal testing system that can evaluate various detergent formulations, concentrations, and conditions within the same apparatus. The standardized washing cells with controlled parameters enable consistent comparison across different test cases, reducing the need for separate testing setups and minimizing overall testing time
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
The method significantly reduces washing time, minimizes mechanical stress on laundry items, and allows for efficient testing of multiple formulations and conditions in a single process, enabling rapid evaluation of detergent effectiveness while maintaining item integrity.
Implementation Method 1
dual asymmetric centrifugation of the washing container loaded with the laundry items and the washing fluid, whereby the washing container is rotated about a primary axis running outside of the washing container, and at the same time about a secondary axis running through the washing container
Implementation Method 2
the washing process takes place not primarily in a traditional manner by mechanical movement of the laundry items within the washing container, but on the basis of diffusion, i.e. by accelerated diffusion of the washing fluid through the laundry items and of the contamination out of the laundry items

AI summary
The invention relates to a method and a device for washing textile items to be washed, wherein the items to be washed and a washing liquid are introduced into a washing container. Then the washing container is dually asymmetrically centrifuged. During the dual asymmetrical centrifuging, the washing container is rotated about a first axis of rotation, which extends outside of the washing container, and simultaneously about a second axis of rotation, which extends through the washing container and is at an acute angle to the first axis of rotation. The washing process is thereby intensified and significantly accelerated.
