Solution Overview

Problem

Existing faucet filters require the removal of the aerator and are cumbersome to install, and they lack versatility for connection to vessels other than faucets.

Innovation Solution

A filter attachment that removably couples with the faucet without removing the aerator, featuring flexible covers for pressure relief and reversible design, allowing for easy cleaning and secondary fitments, enabling quick installation and versatility across different vessels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing faucet filters require removal of the aerator and screwing to a separate structure, then the filter can be installed, but the installation process becomes timely and cumbersome

Engineering Contradiction:
Improvefilter installation stabilityVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The filter attachment is divided into separate components including a filter housing, aerator assembly, and mounting elements that can be independently assembled and installed, enabling quick attachment without complex screwing operations

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The aerator is pre-assembled with the filter components during manufacturing, so that during installation only a single attachment operation is needed rather than multiple assembly steps, significantly reducing installation time

Inventive Principle:
Principle #10Preliminary action

2Device complexity

If existing faucet filters are designed for fixed faucet installation, then the filter structure is simple, but the filter lacks versatility for connection to vessels other than faucets

Engineering Contradiction:
Improvefilter structure complexityVSAvoidvessel connection versatility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The filter attachment incorporates multiple mounting interfaces and adapter configurations that enable it to be installed on various vessel types including faucets, bottles, and containers, making a single device suitable for multiple applications without requiring complex redesign

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The filter design includes adjustable and reconfigurable mounting components that can adapt to different vessel geometries and opening types, allowing the same filter unit to dynamically adjust to various installation scenarios rather than requiring fixed specialized designs

Inventive Principle:
Principle #15Dynamics

AI summary

Disclosed is a filter attachment that removably couples with a faucet or other vessel. The attachment includes a flexible cover holding the filter on the vessel and that acts as a pressure relief mechanism if the water pressure of the faucet is above a predetermined threshold. Another flexible cover may be located on the opposite side of the attachment to allow reversible use and cleaning by backwashing. The attachment may further include a removable cap on one side that includes a flexible cover and that couples to the remainder of the attachment in a removable manner so as to allow other fitments to couple to the attachment.
