Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter arrangements in laundry treatment machines do not ensure optimal and reproducible filling of the receiving space for impurities, leading to inefficient utilization of space and random deposition of impurities.
Innovation Solution
The filter arrangement features passage openings arranged and dimensioned to create a throughput gradient, ensuring that the liquid enters the receiving space in a predetermined manner, with the passage area's total area per unit area decreasing from an initial area to an end area, promoting controlled deposition of impurities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If uniform passage openings are used in the filter arrangement, then the structure is simple and easy to manufacture, but the receiving space is not optimally filled and impurities are deposited randomly
Solution Approach 1:
The passage openings are designed with varying characteristics in different regions of the filter arrangement. Specifically, the openings have different sizes, shapes, or distributions in different zones to create controlled flow patterns that guide liquid and impurities toward specific deposition areas, thereby optimizing space utilization while maintaining manufacturing feasibility
Solution Approach 2:
The passage area is divided into multiple zones with different opening characteristics. This segmentation allows different regions to serve different functions - some areas promote liquid flow while others facilitate impurity deposition, creating a structured filling pattern without requiring overly complex overall design
2Quantity of substance
If a large receiving space is provided for impurity deposition, then more impurities can be stored, but the space utilization becomes inefficient if filling is random
Solution Approach 1:
The filter arrangement is designed with pre-determined flow paths and deposition zones established by the passage opening configuration. This preliminary structuring ensures that as liquid flows through the filter, impurities are systematically directed to specific areas, guaranteeing efficient and reproducible filling of the receiving space from the outset
Solution Approach 2:
The passage openings utilize variations in geometric parameters (size, shape, distribution) to control flow dynamics. By adjusting these parameters across different regions, the system creates optimal conditions for systematic impurity deposition, maximizing the effective utilization of the receiving space volume
3Duration of action of stationary object
If the filter arrangement is designed for long-term lifetime lint deposit, then regular cleaning is reduced, but the available space for impurity storage is limited
Solution Approach 1:
The passage openings are designed with specific dimensional parameters and distributions that optimize both the capacity and duration of filter operation. The varied opening characteristics create efficient flow patterns that maximize impurity capture rate while maintaining structured deposition, enabling the filter to operate effectively for extended periods with adequate storage capacity

This design optimizes the filling of the receiving space by ensuring that impurities are deposited in a preferred direction, maximizing the available space for storage and maintaining a controlled flow, resulting in efficient and orderly filling of the filter area.
Implementation Method 1
the passage openings in the passage area are arranged and/or dimensioned in such a way that there is a throughput gradient for the liquid over the passage area, so that the flowing liquid enters the receiving space in a predetermined manner

AI summary
The filter system comprises a filter device (26) for filtering off impurities (4) carried by a liquid (3) that flows through a laundry treatment machine, and a receiving chamber (20) for the deposition of impurities (4) that are filtered off, said receiving chamber comprising at least one passage region (24) with a plurality of through-openings (28, 29, 30, 31, 32) for the liquid (3). The aim of the invention is to provide a filter system which has a receiving chamber for receiving impurities to be deposited that can be filled in a structured and reproducible way and is thus optimally utilized. The through-openings (28, 29, 30, 31, 32) in the passage region (24) are arranged and/or dimensioned such as to result in a throughput gradient (38) over the passage region (24), the flowing liquid (3) thus flowing through the receiving chamber (20) in a defined manner such that the receiving chamber (20) is filled and the impurities (4) are deposited in a preferred direction (40).
