Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter devices, particularly Bernoulli filters, are limited by their size, which restricts the volume flow of liquids they can filter and require increased pump output during cleaning, leading to operational inefficiencies and reduced availability.
Innovation Solution
A filter device with multiple cylindrical filter elements arranged in parallel, allowing for increased volume flow without significant size increase, and a compact design, where each filter element can be cleaned independently to maintain continuous operation with reduced pump output and backwash volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single filter element is used in conventional Bernoulli filters, then the device structure is simple, but the volume flow capacity is limited and device size is large
Solution Approach 1:
The filter system is divided into multiple filter elements (at least two) that are arranged in parallel within a common housing. Each filter element can be independently cleaned while others remain operational, thereby increasing the overall volume flow capacity without significantly increasing the device size. The housing accommodates multiple filter elements through strategic spatial arrangement.
Solution Approach 2:
The filter elements are arranged in a parallel configuration within the housing, utilizing three-dimensional space efficiently. This spatial arrangement allows multiple filtering paths to coexist within a compact volume, increasing capacity without linearly increasing device dimensions.
2Reliability
If the filter cleaning element is inserted axially into the filter element, then contactless self-cleaning is achieved, but increased pump output is required during cleaning
Solution Approach 1:
The filter system is segmented into multiple independently operable filter elements. During cleaning of one element, the others continue to filter, maintaining system availability. The cleaning operation on individual elements requires reduced pump output compared to cleaning a single element in a conventional system, as the load is distributed across multiple parallel elements.
Solution Approach 2:
The parallel arrangement of filter elements enables continuous filtering operation during cleaning maintenance. While one or more elements are being cleaned, others remain in service, ensuring uninterrupted useful action. This eliminates downtime and maintains high operational availability.
3Productivity
If multiple filter elements are arranged in parallel, then volume flow capacity increases and operational availability improves, but device complexity increases
Solution Approach 1:
Multiple filter elements are merged into a single integrated housing structure with common inlet and outlet connections. The housing unifies the multiple elements, providing a compact assembly that reduces overall structural complexity despite containing multiple components. Shared mounting structures and fluid distribution manifolds simplify the overall device architecture.
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 parallel arrangement of filter elements reduces the overall size of the device, increases the volume flow capacity, and enhances operational readiness by allowing continuous operation during cleaning, with reduced pump output and backwash requirements, improving the filter's efficiency and availability.
Implementation Method 1
This axial insertion of the filter cleaning element increases a flow velocity in an area of an inner surface of the filter element due to the narrowing of the cross section, as a result of which substances adhering to the filter element are flushed away

AI summary
The filter (1) has housing (2) that is provided with an inlet (4a-4d) through which to-be-filtered liquid is admitted and an outlet (14) through which liquid is delivered. Cylindrical filter elements having openings for filtering particles of liquid are formed in housing. A filter cleaning element is inserted in a region of inner surface of filter element, so as to increase the flow rate of liquid in filter element. The filter elements are arranged parallel in main portion. An independent claim is included for method for filtering liquid.
