Solution Overview

Problem

Conventional faux-rust finishing technologies pose health hazards and environmental risks due to the use of acidic solutions and are complex and inconvenient to operate.

Innovation Solution

A flower pot with a faux-rust effect is achieved by applying a layer comprising water, additives, dispersant, lubricant, ethylene glycol, dodecyl alcohol ester, emulsion agent, ferrous metal ore powder, thickener, sterilizing agent, and preservative, using a method that includes a primer, faux-rust effect layer, reactance layer, and finishing layer, allowing for a safer, simpler, and more environmentally friendly process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional faux-rust finishing technology uses acidic solutions to create rusting effects, then the rusting pattern and texture can be achieved, but health hazards and environmental risks increase

Engineering Contradiction:
Improverusting pattern textureVSAvoidhealth hazards and environmental risks
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical composition parameters of the faux-rust solution by replacing acidic components with alkaline components (sodium hydroxide, potassium hydroxide, ammonium hydroxide) and adding organic compounds (acetone, alcohol, ether). This parameter change maintains the ability to create rusting patterns while eliminating the harmful acidic effects on health and environment.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent converts the previously harmful acidic solution into a beneficial alkaline solution that still achieves the desired rusting effect. The harmful acidity is transformed into beneficial alkalinity combined with organic compounds, which creates the same aesthetic rusting pattern without the associated health and environmental hazards.

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

2Manufacturing precision

If conventional faux-rust finishing processes are used to create metal corrosion effects, then the desired texture can be achieved, but the process becomes complex and inconvenient to operate

Engineering Contradiction:
Improvemetal corrosion effect textureVSAvoidprocess complexity
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The patent merges multiple functions into a single faux-rust solution formulation that combines alkaline agents and organic compounds in one mixture. This unified approach simplifies the application process compared to conventional multi-step acidic treatments, making it more convenient to operate while maintaining the desired metal corrosion texture effect.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent creates a simplified copy of the conventional acidic faux-rust process by developing an alkaline-based solution that replicates the rusting pattern and texture effects without requiring the same complex procedural steps. This copied approach achieves identical aesthetic results with greater operational simplicity.

Inventive Principle:
Principle #26Copying
