Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a transparent sealing agent is applied to cementitious products, then the product surface is sealed, but it is difficult to visually ensure adequate coverage and the agent degrades under UV light

Engineering Contradiction:

Improvesealing performanceVSAvoidcoverage verification

Core Design Contradiction:

ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent applies color changes by incorporating pigments into the sealing agent formulation. This allows the sealing agent to be visually detected on the cementitious product surface, enabling workers to verify adequate coverage. The colored sealing agent maintains its sealing function while adding visual detectability to resolve the coverage verification difficulty.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The patent converts the harmful effect of UV degradation into a benefit by using UV-reactive pigments or dyes that change color or intensity when exposed to UV light. This allows the sealing agent to indicate its presence and coverage through color changes triggered by UV exposure, transforming the previously harmful UV factor into a useful detection mechanism.

Inventive Principle:

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

2Reliability

If a transparent sealing agent is applied to cementitious products, then the product surface is sealed, but the agent is susceptible to UV degradation affecting adhesion

Engineering Contradiction:

Improvesealing performanceVSAvoidUV degradation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent converts the harmful effect of UV degradation into a benefit by using UV-reactive pigments or dyes that change color or intensity when exposed to UV light. This allows the sealing agent to indicate its presence and coverage through color changes triggered by UV exposure, transforming the previously harmful UV factor into a useful detection mechanism.

Inventive Principle:

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

Solution Approach 2:

The patent applies composite materials by formulating the sealing agent as a composite system containing resin, pigment, and optionally filler materials. This composite formulation provides both the sealing function and UV resistance, with the pigment component protecting against UV degradation while the resin provides adhesion and sealing performance.

Inventive Principle:

Principle #40Composite materials

3Productivity

If a paint coat is applied directly onto a sealing agent, then the coating process is simplified, but the sealing agent does not provide sufficient adhesion

Engineering Contradiction:

Improvecoating process efficiencyVSAvoidadhesion

Core Design Contradiction:

ProductivityVSStrength

Solution Approach 1:

The patent applies composite materials by formulating the sealing agent as a composite system containing resin, pigment, and optionally filler materials. This composite formulation provides both the sealing function and UV resistance, with the pigment component protecting against UV degradation while the resin provides adhesion and sealing performance.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent applies parameter changes by modifying the chemical composition parameters of the sealing agent formulation. By adjusting the resin type, pigment concentration, and filler content, the patent optimizes both adhesion strength and sealing performance, enabling direct paint application over the sealing agent.

Inventive Principle:

Principle #35Parameter changes
