Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If conventional deicing agents like sodium chloride are used, then deicing effect is achieved, but the duration of action is short and repeated application is needed

Engineering Contradiction:
Improveduration of deicing effectVSAvoidfrequency of application
Core Design Contradiction:
Duration of action of moving objectVSQuantity of substance

Solution Approach 1:

The patent combines conventional deicing agents (sodium chloride, calcium chloride, etc.) with organic additives including proteins (casein, whey, soy), molasses, and carbohydrates to create a composite deicing composition. This composite formulation extends the duration of deicing effect by improving adhesion to road surfaces and reducing premature wash-off, allowing the deicing agent to remain effective for longer periods without repeated applications.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The organic additives (proteins, molasses, carbohydrates) act as intermediaries that enhance the performance of conventional deicing agents. These substances improve wetting properties, increase adhesion to asphalt and concrete surfaces, and modify the release characteristics of the deicing agent, thereby extending its effective duration on the road surface.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If deicing agents are applied frequently to maintain effectiveness, then deicing performance is maintained, but damage to road surfaces increases due to repeated freezing and thawing

Engineering Contradiction:
Improvedeicing performanceVSAvoiddamage to road surfaces
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The composite formulation with organic additives reduces the need for repeated applications by extending the duration of each application's effectiveness. This decreases the number of freezing-thawing cycles that deicing agents induce in porous asphalt, thereby reducing mechanical stress and damage to road surfaces while maintaining reliable deicing performance.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The invention modifies the physical and chemical parameters of deicing compositions by adding organic substances that alter adhesion, wetting, and release characteristics. These parameter changes allow for less frequent applications, reducing the cumulative harmful effects on road surfaces while maintaining effective deicing performance throughout winter conditions.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If highly porous asphalt is used to improve drainage, then safety under rainy conditions is improved, but more deicing agent is needed as it flows away with melt water

Engineering Contradiction:
Improvesafety under rainy conditionsVSAvoidamount of deicing agent needed
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The organic additives (proteins, molasses, carbohydrates) serve as intermediaries that improve the adhesion of deicing agents to highly porous asphalt surfaces. These substances enhance wetting properties and create a bonding effect that prevents deicing agents from being washed away by melt water, thereby reducing the total quantity needed while maintaining effectiveness on drainage-improved surfaces.

Inventive Principle:
Principle #24Intermediary (Mediator)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The combination of native protein and molasses in the deicing composition improves deicing agent retention and reduces surface damage by maintaining effectiveness over a longer period and minimizing corrosion, thus reducing maintenance needs and safety risks.

Implementation Method 1

The sodium chloride works as a deicing agent by dissolving into precipitation on roadways and lowering the freezing point, thereby melting ice and snow

Methodology Applied
Scientific EffectFreezing point depression:

Implementation Method 2

due to better adhesion properties of the deicing composition compared to use of the deicing agent alone, less deicing agent will be blown away and the deicing agent is retained on the road for a longer period of time

Methodology Applied
Scientific EffectAdhesion: Adhesive

Implementation Method 3

When the air/ground temperature becomes sufficiently low, an aqueous solution which is present in the channels of the asphalt will expand upon freezing, thus, creating mechanical stress in the asphalt

Methodology Applied
Scientific EffectThermal expansion: Thermal Expansion
