Solution Overview

Problem

Existing water extractors in environmental control systems are bulky and consume large amounts of space, and multiple extractors are fluidly coupled to different components, leading to inefficiencies.

Innovation Solution

A water separator with a condensing material insert that directs airflow radially through sidewalls with discrete flow passages, allowing moisture to coalesce and be collected efficiently, potentially eliminating the need for a separate water collector.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional water extractors are used in environmental control systems, then moisture removal function is provided, but device volume and space consumption increase

Engineering Contradiction:
Improvemoisture removal functionVSAvoiddevice volume
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The patent combines the water separation function and water collection function into a single integrated water extractor assembly. The separator component directs moisture to the collector component within the same housing, eliminating the need for separate extraction and collection devices. This merging reduces overall device volume while maintaining effective moisture removal capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The water extractor assembly performs multiple functions within a single device: it separates moisture from airflow, collects the separated moisture, and provides a unified drainage solution. This multi-functionality allows the device to replace what would traditionally require multiple separate components, thereby reducing space consumption while maintaining comprehensive moisture management.

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

2Reliability

If multiple separate water extractors are used in environmental control systems, then moisture removal is achieved, but system complexity and fluid coupling requirements increase

Engineering Contradiction:
Improvemoisture removalVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates separation and collection functions into one assembly, reducing the number of separate extractors needed in the system. This consolidation simplifies fluid coupling requirements and reduces system complexity while maintaining effective moisture removal across the environmental control system.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If traditional bulky water extractors are used, then moisture separation is achieved, but space efficiency deteriorates

Engineering Contradiction:
Improvemoisture separationVSAvoidspace efficiency
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The collector component is positioned within or adjacent to the separator component, with both housed in a compact integrated structure. The moisture-separated airflow passes from the separator directly into the collector portion, creating a nested or tightly coupled arrangement that minimizes the overall footprint while maintaining effective moisture separation and collection.

Inventive Principle:
Principle #7Nested doll (Nesting)
