Solution Overview

Problem

Panels installed with bevels are susceptible to liquid penetration at the joints, leading to moisture absorption and swelling, and existing moisture protection methods are inadequate.

Innovation Solution

A method involving forming a bevel between panel edges and impregnating them with an impregnating agent, such as 2-methoxy-methylethoxy-propanol, to create a moisture-resistant seal that overlaps with subsequent surface finishes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If bevels are formed on panel edges to improve appearance and chip resistance, then aesthetic quality and edge durability are improved, but liquid penetration susceptibility increases due to V-shaped joints collecting water

Engineering Contradiction:
Improvebevel shapeVSAvoidliquid penetration
Core Design Contradiction:
ShapeVSObject-affected harmful factors

Solution Approach 1:

The panel edges are impregnated with hydrophobic agents before installation, creating a preventive moisture barrier that blocks liquid penetration at the bevel joints before water can collect and infiltrate the panel structure

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The V-shaped bevel joints that naturally collect water are treated with hydrophobic impregnation, converting the harmful water collection property into a beneficial feature where the same geometric structure that collects water now channels water away due to surface tension effects on the hydrophobic-treated surface

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

2Ease of operation

If panels are installed with floating joints to allow flexibility and easy replacement, then installation ease and adaptability are improved, but moisture protection deteriorates as joints become susceptible to liquid penetration

Engineering Contradiction:
Improveinstallation easeVSAvoidmoisture protection
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

Panels are pre-impregnated with hydrophobic agents at the factory before installation, ensuring moisture protection is built into the panel structure itself rather than relying on post-installation sealing of joints, thus maintaining both installation flexibility and moisture protection

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The hydrophobic impregnation is applied specifically to the panel edges and bevel surfaces where moisture penetration is most likely to occur, providing localized protection at critical areas without affecting the overall floating installation system

Inventive Principle:
Principle #3Local quality

3Device complexity

If panel edges are left exposed to allow simple construction, then manufacturing complexity is reduced, but moisture absorption and swelling increase

Engineering Contradiction:
Improveconstruction simplicityVSAvoiddimensional stability
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The panel edges perform self-protection through hydrophobic impregnation, where the treated surface automatically repels moisture without requiring additional protective structures or complex sealing mechanisms, thus maintaining construction simplicity while ensuring dimensional stability

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The surface properties of panel edges are modified through chemical impregnation, changing the hydrophobicity parameter of the edge materials to create a moisture-resistant barrier that prevents water absorption and maintains dimensional stability under varying humidity conditions

Inventive Principle:
Principle #35Parameter changes
