Solution Overview

Problem

The increasing number of household appliances with individual water filters leads to management inefficiencies, increased replacement costs, and potential incompatibilities, while hub-type systems may provide high-level purification leading to rapid filter exhaustion and insufficient water supply.

Innovation Solution

A centralized water purification apparatus with multiple filters and customizable purification paths provides purified water to various appliances, allowing for different levels of purification and ensuring sufficient supply.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If each home appliance includes a separate water filter, then water purification can be performed for each appliance, but the management becomes complex and replacement costs increase

Engineering Contradiction:
Improvewater purification qualityVSAvoidfilter management complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent consolidates multiple water filters into a single hub-type water purification apparatus that serves multiple home appliances. Instead of each appliance having its own filter, the filters are merged into one centralized system with multiple outlet ports, simplifying management while maintaining purification quality for each appliance.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The hub-type water purification apparatus is designed to serve multiple functions and multiple appliances simultaneously. A single purification system provides purified water to various appliances through different outlet ports, making the system universal and eliminating the need for separate filters in each appliance.

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

2Reliability

If each home appliance includes a water filter, then water purification is available for each appliance, but the appliance size increases

Engineering Contradiction:
Improvewater purification capabilityVSAvoidappliance volume
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The water filter function is extracted from individual home appliances and placed into a separate hub-type purification apparatus. This allows the appliances to be smaller since they no longer need to accommodate filter components, while the purification capability is maintained through the external hub system.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If different home appliances use different water filters, then each appliance can be optimized for its specific needs, but compatibility issues arise and maintenance becomes inconvenient

Engineering Contradiction:
Improveappliance-specific optimizationVSAvoidfilter compatibility and maintenance
Core Design Contradiction:
Adaptability or versatilityVSEase of repair

Solution Approach 1:

The hub-type water purification apparatus uses a standardized filter system that serves all connected appliances uniformly. This universal approach eliminates compatibility issues between different appliances while maintaining ease of maintenance, as all filters are identical and can be replaced in a single location regardless of which appliance requires purified water.

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

4Reliability

If the hub-type water purification apparatus provides high-level purified water to all appliances, then water quality is consistent, but the filter exhausts rapidly and sufficient purified water cannot be generated

Engineering Contradiction:
Improvewater quality consistencyVSAvoidfilter service life
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The hub-type water purification apparatus provides different levels of purification for different outlet ports based on the specific needs of each connected appliance. Not all outlets require the same high level of filtration, so the system applies appropriate purification levels locally to each outlet, extending filter life while maintaining sufficient water quality for each application.

Inventive Principle:
Principle #3Local quality
