Solution Overview

Problem

Existing fluid treatment devices, such as humidifiers and coolers, face challenges in optimizing fluid flow resistance and surface contact area between mat elements, which affects the efficiency of gas treatment and cooling processes.

Innovation Solution

The installation device features mat elements with a thickness gradient, allowing for vertical alignment and application of water as a working fluid, which flows and drips along the surface, creating an enlarged contact area with the treated fluid in counter-current or cross-current flow configurations, utilizing corrugated or lattice structures to enhance surface exposure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If mat elements are arranged with constant thickness, then manufacturing is simple, but flow resistance increases and surface contact area is reduced

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidflow efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The mat elements are designed with a thickness gradient, where the thickness varies continuously from one side to the other. This local variation in thickness optimizes the flow properties by reducing flow resistance in thicker regions and increasing surface contact area in specific zones, while maintaining manufacturing feasibility through extrusion or molding processes that can accommodate gradual thickness changes.

Inventive Principle:
Principle #3Local quality

2Ease of operation

If mat elements are arranged vertically aligned, then installation is simplified, but surface contact area with working fluid is reduced

Engineering Contradiction:
Improveinstallation simplicityVSAvoidsurface contact area
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The mat elements are designed with a thickness gradient that introduces a dimensional variation along the vertical alignment. While the elements remain vertically aligned for easy installation, the varying thickness creates additional surface area exposure to the working fluid, effectively utilizing the thickness dimension to increase contact area without compromising installation simplicity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Productivity

If working fluid flows parallel to mat elements, then flow resistance is low, but surface contact time is reduced

Engineering Contradiction:
Improveflow rateVSAvoidcontact time
Core Design Contradiction:
ProductivityVSDuration of action of moving object

Solution Approach 1:

The thickness gradient creates a curved or inclined surface profile on the mat elements rather than a flat parallel surface. This curvature causes the working fluid to follow a more extended path along the mat element surface, increasing contact time while maintaining relatively low flow resistance. The gradual thickness variation guides the fluid flow smoothly along the inclined surfaces.

Inventive Principle:
Principle #14Spheroidality (Curvature)
