Solution Overview

Problem

In easily polymerizable substance treatment apparatuses, the horizontal upper surface of support beams leads to liquid adhesion and polymerization, causing blockages in vapor-liquid flow paths and reducing treatment efficiency, which is typically addressed by increasing polymerization inhibitor usage, making it uneconomical.

Innovation Solution

A support beam with a folded-back portion inclined downward at an angle (0°<α<90°, preferably 5°<α<60°) to prevent liquid adhesion and polymerization, allowing liquids to flow freely and reducing polymer formation without increasing inhibitor amounts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the folded-back portion of the support beam has a horizontal upper surface, then the structural stability and reinforcement effect are improved, but liquid adhesion occurs leading to polymerization and blockage of vapor-liquid flow paths

Engineering Contradiction:

Improvestructural stabilityVSAvoidliquid adhesion and polymerization

Core Design Contradiction:

StrengthVSObject-generated harmful factors

Solution Approach 1:

The patent applies asymmetry by changing the folded-back portion from a symmetric horizontal surface to an asymmetric inclined surface. The inclination angle α is set between 5° and 60°, creating an asymmetric geometry that prevents liquid accumulation while maintaining structural stability. This asymmetric design ensures liquid flows off the surface rather than adhering to it.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The patent applies curvature by replacing the flat horizontal surface with an inclined surface that has a specific angular orientation. This curved/angled surface design prevents liquid from pooling by creating a slope that directs liquid flow away from the support beam structure, thereby preventing polymerization.

Inventive Principle:

Principle #14Spheroidality (Curvature)

2Reliability

If polymerization inhibitor amount is increased to prevent polymerization on the horizontal surface, then polymerization prevention is improved, but treatment economy deteriorates

Engineering Contradiction:

Improvepolymerization preventionVSAvoidpolymerization inhibitor consumption

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The patent extracts the polymerization problem from its root cause (liquid accumulation on horizontal surfaces) by removing the horizontal surface geometry. By taking out the problematic horizontal configuration and replacing it with an inclined surface, the need for polymerization inhibitors is eliminated, thus preventing polymerization without increasing chemical consumption.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent converts the potentially harmful effect of liquid adhesion into a beneficial flow pattern. By designing the inclined surface, the liquid that would normally adhere and cause polymerization is now directed to flow freely off the surface. This converts the harmful adhesion effect into a beneficial self-cleaning flow pattern that prevents polymerization without requiring additional chemicals.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Ease of manufacture

If the support beam uses a conventional horizontal folded-back portion, then ease of manufacture is improved, but treatment efficiency deteriorates due to blockages

Engineering Contradiction:

Improvesupport beam fabricationVSAvoidtreatment efficiency

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The patent applies parameter changes by modifying the geometric parameter of the folded-back portion from a horizontal angle (0°) to an inclined angle (α between 5° and 60°). This parameter change maintains ease of manufacture through standard fabrication processes while dramatically improving treatment efficiency by preventing liquid accumulation and polymerization that would block vapor-liquid flow paths.
