Pool Filter With Universal Openings and Anchoring Footings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pool filters face limitations in design flexibility due to single inlet and outlet arrangements, often requiring different sized fittings and tools, and lack anchoring mechanisms, which can lead to instability during seismic events, potentially causing hazardous chemical leaks.
Innovation Solution
A pool filter design with multiple equally sized openings for fluid inlet, outlet, and drain, and an anchoring system using footings with anchor members to secure the filter to a support surface, allowing for universal fittings and enhanced stability against natural disasters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single inlet and outlet arrangement is used, then the pool filter structure is simple, but the flexibility in piping system design is limited
Solution Approach 1:
The housing is designed with multiple openings of substantially the same size that can serve different functions (inlet, outlet, drain) depending on the piping configuration. This universal design allows the same housing structure to accommodate various piping layouts without requiring different sized openings, thereby increasing adaptability while maintaining structural simplicity.
2Ease of manufacture
If the drain outlet is made smaller than the fluid inlet and outlet, then the housing structure is simplified, but different sized fittings and tools are required increasing manufacturing costs
Solution Approach 1:
The drain outlet opening is designed to be substantially the same size as the fluid inlet and outlet openings, rather than being smaller. This parameter change eliminates the need for different sized fittings and tools, simplifying manufacturing processes and reducing costs while maintaining structural simplicity.
3Reliability
If the pool filter is set directly on pads without anchoring, then the installation is simple, but the filter may tip over during earthquakes or hurricanes causing chemical leaks
Solution Approach 1:
The anchoring system is integrated into the housing structure in advance, with features such as openings for anchor bolts or interlocking mechanisms that allow the filter to be securely anchored to the support surface during installation. This preliminary incorporation of anchoring capabilities ensures stability during seismic events without requiring complex separate anchoring components.

AI summary
A pool filter for use in pool piping or other fluid conveyance system. The pool filter may include a housing defining a fluid chamber for receiving one or more filters. Multiple openings may be defined in the housing for receiving and removing fluid from the fluid chamber. The openings may be approximately the same size and may be located on the housing at similar elevations and/or radial sectors. One or more footings may be joined to the housing. Each footing may include a base portion for receiving anchor members to anchor the housing to a support surface. The footings may be designed to transfer to the support surface predetermined lateral or other forces imposed upon the pool filter by events such as earthquakes and hurricanes. The footings may be separate components joined to the housing by tabs and/or mechanical fasteners.
