Compostable Water Filter with Gasket Seal and Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water filter pitchers often experience filter housing dislodgment during pouring, leading to spills due to poor seating of the filter assembly, and they lack efficient mechanisms for controlling water flow and easy cleaning.
Innovation Solution
A water filtration apparatus with a conically-shaped vessel and filter assembly featuring a gasket for secure seating, drip ports, and a pour channel system that includes flow control tabs and a biodegradable filter device with replaceable components for easy maintenance and composting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional plastic filter housing is used, then the filter can be easily manufactured and assembled, but the filter assembly becomes dislodged during pouring causing spills
Solution Approach 1:
The patent employs a flexible gasket seal between the filter housing and pitcher body that can deform to maintain a secure seal during pouring operations. This flexible sealing mechanism prevents the filter assembly from becoming dislodged while maintaining ease of operation during pouring.
2Reliability
If the filter housing is securely sealed to prevent spills, then backflow prevention is improved, but cleaning access becomes difficult
Solution Approach 1:
The filter assembly is segmented into separable components including the filter housing, gasket, and filter insert. This segmentation allows the components to be easily removed for cleaning while maintaining a secure sealed connection during operation to prevent backflow and spills.
3Reliability
If a non-biodegradable plastic filter housing is used, then the housing is durable and reusable, but it cannot be composted and creates environmental waste
Solution Approach 1:
The patent transitions the filter housing material from conventional non-biodegradable plastic to a biodegradable material that maintains sufficient structural durability during use but can be composted after the filter insert is removed, thereby reducing environmental waste while maintaining operational reliability.
4Ease of manufacture
If the filter insert is permanently fixed in the housing, then assembly simplicity is improved, but replacement and maintenance become difficult
Solution Approach 1:
The filter insert is designed with a dynamic, removable connection to the housing that allows for easy insertion and replacement. This dynamic design enables simple assembly during manufacture while facilitating convenient filter insert replacement during maintenance without compromising the overall assembly simplicity.
