Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deicing solutions are either corrosive, environmentally harmful, ineffective at low temperatures, or require complex applicators, and they often produce dust and debris, failing to provide a universal, eco-friendly, and easy-to-use deicing liquid formulation.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If chloride salts (NaCl, MgCl2, CaCl2) are used for deicing, then deicing effectiveness is improved, but corrosion damage to vehicles and infrastructure increases
Solution Approach 1:
The patent changes the chemical composition parameters by replacing chloride salts with non-chloride alternatives (acetates, formates, carbamates, oxalates, succinates), fundamentally altering the chemical properties to eliminate corrosion while maintaining deicing effectiveness through freezing point depression
Solution Approach 2:
The patent uses composite material formulations combining multiple non-chloride deicing agents with complementary properties (e.g., calcium magnesium acetate combined with other salts) to achieve both effective deicing and environmental compatibility, creating a synergistic mixture that addresses both performance and corrosion concerns
2Object-affected harmful factors
If non-chloride deicers (acetates, formates) are used, then corrosion is reduced, but dust emissions increase
Solution Approach 1:
The patent combines non-chloride deicing agents with dust suppressant materials (clay, cement, organic polymers) in composite formulations, where the dust suppressants bind to particles and reduce airborne dust while the non-chloride salts provide deicing function, simultaneously addressing both concerns
Solution Approach 2:
The patent introduces dust suppressant materials as intermediary substances that mediate between the non-chloride deicing agents and the environment, preventing dust generation from the deicer application while allowing the deicing chemicals to perform their function
3Temperature
If deicing formulations are applied at temperatures below -9°C, then deicing action is maintained, but reaction speed decreases
Solution Approach 1:
The patent adjusts chemical composition parameters by selecting deicing agents with appropriate solubility and reaction characteristics for low-temperature conditions, and optimizes concentration ratios to ensure rapid dissolution and effective freezing point depression even at sub-freezing temperatures
Solution Approach 2:
The patent introduces solvents and surfactants as intermediary substances that facilitate rapid dissolution and distribution of deicing agents on ice surfaces, enhancing reaction speed by improving contact and dissolution kinetics before the chemical deicing action begins
4Speed
If liquid deicers are used instead of granular products, then deicing speed is improved, but applicator complexity increases
Solution Approach 1:
The patent optimizes viscosity parameters of the liquid deicer formulation to ensure it flows easily through simple spray equipment while maintaining effective application coverage, adjusting concentration and additive ratios to achieve ideal rheological properties for conventional applicators
