Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pool and spa filters are not designed to be rolled or unrolled for use and cleaning, limiting their flexibility and efficiency in filtering debris-laden water.
Innovation Solution
A filter assembly that can be rolled into a spiral shape for use and unrolled for cleaning, featuring mesh panels with spacers creating gaps for fluid flow and adjustable mesh sizes to bypass clogged areas, allowing continuous filtration and easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a filter is designed as a traditional fixed structure, then it provides stable filtration, but it cannot be easily cleaned or maintained
Solution Approach 1:
The filter assembly is designed to be dynamically configurable between rolled and unrolled states. The mesh panels and framework can be unrolled from a compact rolled position to an extended cleaning position, allowing easy access to all filter surfaces for maintenance while maintaining a space-efficient rolled configuration for operation.
Solution Approach 2:
The filter assembly is divided into multiple mesh panels (first, second, third panels) that can be independently accessed and cleaned. Each panel is separated by spacers, allowing targeted cleaning of specific sections without requiring complete disassembly of the entire filter structure.
2Productivity
If mesh panels are placed close together to maximize filtration area, then filtration efficiency increases, but cleaning becomes difficult
Solution Approach 1:
Spacers are introduced as intermediary elements between adjacent mesh panels. These spacers maintain optimal spacing that allows cleaning fluid to flow between panels while keeping the panels close enough to maximize filtration surface area within the available space.
Solution Approach 2:
The spacers extract the cleaning function from the panel structure itself, providing dedicated channels for cleaning fluid flow. This separation allows the mesh panels to be positioned closely for maximum filtration area while the spacers ensure cleaning accessibility.
3Stability of the object's composition
If the filter structure is made rigid for structural stability, then it maintains shape during operation, but it cannot be rolled or folded for storage and cleaning
Solution Approach 1:
The framework is constructed with flexible components including flexible ribs that connect the mesh panels. These flexible elements provide structural stability during operation while allowing the entire assembly to be rolled and unrolled for storage and cleaning operations.
Solution Approach 2:
The framework transitions from a rigid static structure to a dynamic flexible structure. The flexible ribs and connection points allow the framework to adapt its configuration, maintaining structural integrity when extended for filtration while enabling rolling motion for storage and access.
4Adaptability or versatility
If a single mesh size is used throughout the filter, then the structure is simple, but it cannot adapt to different debris sizes or clogging patterns
Solution Approach 1:
Different mesh panels are equipped with different mesh sizes tailored to specific filtration needs. The first, second, and third panels can have progressively different opening sizes, allowing each section to handle specific debris size ranges. This local differentiation improves overall filtration adaptability without requiring complete system redesign.
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
Enables efficient debris filtration with adjustable mesh sizes and bypass capabilities, facilitating easy cleaning and maintaining filtration efficiency even when panels become clogged.
Implementation Method 1
mesh panels of the assemblies need not necessarily be sized identically, hence providing different levels of debris filtration within a single assembly
Implementation Method 2
fluid may be capable of flowing through at least some panels and at least some gaps so that obstruction of one path does not prevent flow through an assembly
Data Source
AI summary
Filter assemblies are described which may be rolled for use and unrolled for cleaning. Rolling an assembly may form a spiral path for fluid to flow. Fluid also may flow through mesh panels of the assembly unless such panels are obstructed, as by debris.
