Solution Overview

Problem

Existing gas humidification, cleaning, and cooling devices face inefficiencies due to high flow resistance, suboptimal gas-moisture exchange, and structural instability, particularly in larger systems, where plate elements can lead to instability and are difficult to clean without damage.

Innovation Solution

The solution involves creating a self-stabilizing installation element with offset plate elements arranged in multiple dimensions, connected via snap-in or pin-hole connections, and featuring perforated corrugated plastic or grid mat designs for enhanced gas-liquid interaction, reducing flow resistance and improving moisture retention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If plate elements are arranged in close contact to form channels for gas flow, then gas treatment function is achieved, but flow resistance increases and gas-moisture exchange efficiency decreases

Engineering Contradiction:
Improvegas treatment efficiencyVSAvoidflow resistance
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent transitions from traditional planar plate arrangements to a three-dimensional hollow spherical structure with radially extending channels. This dimensional change allows gas to flow through multiple pathways simultaneously (radial, tangential, and axial directions), dramatically reducing flow resistance while increasing the effective gas-liquid contact surface area for improved treatment efficiency

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

Solution Approach 2:

The hollow spherical elements create an inherently porous three-dimensional structure with numerous interconnected channels and void spaces. This porous architecture provides multiple flow paths for gas while maintaining large surface area for moisture exchange, effectively resolving the contradiction between flow resistance and treatment efficiency

Inventive Principle:
Principle #31Porous materials

2Quantity of substance

If plate elements are made large to increase wetting surface area, then moisture retention improves, but structural stability decreases in larger systems

Engineering Contradiction:
Improvemoisture retentionVSAvoidstructural stability
Core Design Contradiction:
Quantity of substanceVSStability of the object's composition

Solution Approach 1:

The patent divides the wetting surface into numerous small hollow spherical elements rather than using few large plate elements. Each sphere maintains structural stability while collectively providing extensive wetting surface area. The modular spherical units can be arranged in stable configurations without the instability problems of large-scale plate structures

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention uses composite construction with hollow spherical shells containing internal support structures (such as radial ribs or nested spheres). This composite design maintains structural integrity and stability while preserving the hollow interior space for gas flow and the outer surface for moisture retention

Inventive Principle:
Principle #40Composite materials

3Ease of manufacture

If paper plate elements are used for gas flow channels, then ease of manufacture improves, but cleanability deteriorates due to risk of destruction

Engineering Contradiction:
Improvemanufacturing easeVSAvoidcleanability
Core Design Contradiction:
Ease of manufactureVSEase of repair

Solution Approach 1:

The patent employs plastic materials for the hollow spherical elements, which are more durable and cleanable than paper. While plastic may be slightly more complex to manufacture than paper, the ability to thoroughly clean and maintain the structure without risk of destruction provides long-term operational advantages that outweigh the minor manufacturing complexity increase

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

4Ease of repair

If plastic plate elements are used instead of paper, then cleanability improves, but gas-moisture exchange efficiency remains suboptimal

Engineering Contradiction:
ImprovecleanabilityVSAvoidgas-moisture exchange efficiency
Core Design Contradiction:
Ease of repairVSProductivity

Solution Approach 1:

The patent creates a three-dimensional arrangement of hollow spheres with radially extending channels, transforming the traditional two-dimensional plate structure. This dimensional change provides vastly increased surface area for gas-moisture exchange while maintaining the cleanability advantages of plastic material. The radial channel configuration ensures efficient gas flow through the moisture-retaining structure

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

Solution Approach 2:

The use of spherical geometry provides optimal surface area to volume ratio, maximizing the wetting surface area available for gas-moisture exchange. The curved spherical surfaces and radial channels facilitate efficient gas flow patterns and moisture distribution, achieving superior exchange efficiency compared to flat plastic plates

Inventive Principle:
Principle #14Spheroidality (Curvature)
