Solution Overview

Problem

Existing water sediment filter assemblies require shutting off the water supply to clean accumulated sediment, which is inconvenient and disrupts water flow.

Innovation Solution

A water sediment filter assembly with a housing having an upper and lower section, where the lower section is removably coupled to the upper section, and includes a flow diversion member, a screen member, and a drain port with a valve system that allows for easy sediment clearance without shutting off the water supply.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a drain port is added to empty accumulated sediment, then sediment clearing capability is improved, but the water supply must still be shut off to clean the sediment

Engineering Contradiction:

Improvesediment clearing capabilityVSAvoidwater supply interruption time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

A three-way valve is introduced as an intermediary component that mediates between the inlet, outlet, and drain port. This valve enables selective connection between different ports, allowing sediment to be directed to the drain port while maintaining water flow through the filter assembly, thus eliminating the need to shut off water supply for cleaning

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The three-way valve is designed to be rotatable or movable between different positions, dynamically changing the flow path configuration. By rotating the valve body, the operator can switch between normal filtration mode and sediment draining mode, enabling flexible operation without water supply interruption

Inventive Principle:

Principle #15Dynamics

2Ease of repair

If the lower section is removably coupled to the upper section, then ease of maintenance is improved, but device complexity increases

Engineering Contradiction:

Improveease of maintenanceVSAvoidhousing structure complexity

Core Design Contradiction:

Ease of repairVSDevice complexity

Solution Approach 1:

The housing is segmented into an upper section and a lower section that are removably coupled together. The lower section containing the screen and sediment collection chamber can be independently removed for cleaning and maintenance, while the upper section remains in place, simplifying the maintenance process without requiring complete disassembly of the entire filter assembly

Inventive Principle:

Principle #1Segmentation
