Pool Filter Lid Assembly with Biasing Clips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and complexity of large pool filter systems, particularly due to oversized housings and cumbersome maintenance access, pose challenges for manufacturers and consumers alike, as existing designs require expensive molds and difficult maintenance procedures.
Innovation Solution
A pipeline filter assembly with a base assembly, outer wall, and lid assembly featuring a self-threading mechanism with lock notches and biasing clips, allowing for easy disengagement and re-engagement of the lid for maintenance, reducing the need for oversized molds and improving accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If larger filter housings are used to provide adequate filtering surface area, then filtering efficiency is improved, but manufacturing cost and device complexity increase
Solution Approach 1:
The filter housing is divided into multiple segments: a base assembly with support collar, an outer wall section, and a lid assembly with upper collar. This segmentation allows each component to be manufactured separately using smaller, less expensive molds while maintaining the overall filtering surface area through the distributed structure of multiple components working together.
2Reliability
If larger filter housings are used to accommodate bigger filters, then filtering capacity is improved, but housing size and material requirements increase
Solution Approach 1:
The segmented housing components nest together efficiently: the base assembly supports the outer wall section, which in turn supports the lid assembly. This nested arrangement maximizes the use of internal volume for the filter element while minimizing the external housing volume, as each segment fits within the overall footprint of the previous segment.
3Device complexity
If traditional filter lid designs are used, then structural simplicity is maintained, but maintenance accessibility deteriorates
Solution Approach 1:
The lid assembly is designed with dynamic fastening features including biasing clips and spring-loaded latches that allow the lid to be easily opened and closed. The biasing clips engage with the outer wall section to secure the lid during operation, while the spring-loaded latches provide automatic engagement and disengagement, making maintenance accessible without requiring excessive force or complex tools.
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
This design reduces production costs by allowing smaller molds and easier maintenance, making the filter system more affordable and user-friendly while maintaining a watertight seal and efficient filtration.
Implementation Method 1
The lid assembly can include at least one biasing spring wherein an end of the biasing spring abuts the interior surface of the housing and biases its corresponding biasing clip to a locked position around a corresponding lock notch.
Implementation Method 2
The upper collar has at least one housing that projects from the upper collar, the housing having an interior surface, and at least one biasing clip pivotally mounted within the housing for releasable engagement with the lock notch.
