Solution Overview

Problem

Portable water filtering systems are inefficient in allowing immediate consumption of filtered water without contamination, lack a method for easy dispensing within refrigerators, and fail to provide real-time indication of filter effectiveness or water quality.

Innovation Solution

A water pitcher system with a container design that includes separate regions for unfiltered and filtered water, a valve assembly for dispensing filtered water without removing the system from storage, and a meter housing for testing water quality using a total dissolved solids meter.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the user waits for water to completely filter through the filter before dispensing, then the filtered water quality is maintained, but the user experiences loss of time and reduced productivity

Engineering Contradiction:
Improvefiltered water qualityVSAvoidwaiting time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The container is divided into an upper chamber for unfiltered water and a lower chamber for filtered water, with the filter positioned between them. This segmentation allows filtered water to be dispensed from the lower chamber while unfiltered water continues to filter above, enabling simultaneous dispensing and filtering operations without contamination risk.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system pre-filters water into the lower chamber before dispensing is needed. Once filtered water accumulates in the lower chamber, it can be dispensed immediately without waiting for the filtering process to complete, as the filter continues operating on unfiltered water in the upper chamber.

Inventive Principle:
Principle #10Preliminary action

2Loss of time

If the user tips the container to dispense small amounts of water during filtering, then immediate consumption is possible, but plain tap water contaminates the filtered water

Engineering Contradiction:
Improveimmediate consumptionVSAvoidwater quality
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The container is divided into an upper chamber for unfiltered water and a lower chamber for filtered water, with the filter positioned between them. This segmentation allows filtered water to be dispensed from the lower chamber while unfiltered water continues to filter above, enabling simultaneous dispensing and filtering operations without contamination risk.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The filter acts as an intermediary barrier between the upper chamber containing unfiltered water and the lower chamber containing filtered water. This intermediary structure prevents direct contact and potential contamination between the two water types, allowing independent access to either chamber.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If the system is removed from the refrigerator for dispensing, then easy access to filtered water is achieved, but water spills and collisions with other items occur

Engineering Contradiction:
Improvedispensing accessibilityVSAvoidwater spills
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The dispensing valve assembly is extracted from the main container body and positioned separately, allowing the user to operate the valve to dispense water without removing the entire container from the refrigerator. This separates the dispensing function from the storage function, enabling easy access while maintaining stable storage.

Inventive Principle:
Principle #2Taking out (Extraction)

4Ease of operation

If the filter is replaced based on estimated usage or visual indicators, then the system is simple to operate, but the consumer may replace the filter too soon or too late

Engineering Contradiction:
Improvefilter replacement simplicityVSAvoidactual filter effectiveness
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

A TDS meter is integrated into the system to provide real-time feedback on the quality of filtered water by measuring total dissolved solids. This objective measurement allows the user to determine when the filter actually needs replacement based on its performance rather than estimates, preventing both premature and delayed replacement.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The subjective visual indicators or calendar-based filter replacement systems are replaced with an objective electronic TDS measurement system. This substitution provides accurate, real-time data on filter effectiveness, replacing the mechanical/calendar-based estimation method with a scientific measurement approach.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
