Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional car waxes lack high water-repellency and effective water-droplet rolling performance, which are essential for maintaining the cleanliness and longevity of surfaces.
Innovation Solution
A composition comprising 100 parts by weight of wax, 0.1 to 40 parts by weight of silicone oil, 10 to 500 parts by weight of C6 to C30 hydrocarbon mixtures, 1 to 200 parts by weight of nano-particles, and 1 to 40 parts by weight of resin, which forms a hydrophobic film on surfaces, enhancing water-repellency and water-droplet rolling performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional car waxes with wax as main component are used, then workability and gloss are improved, but water-repellency and water-droplet rolling performance are insufficient
Solution Approach 1:
The patent uses a composite formulation combining multiple wax types (petroleum wax, beeswax, carnauba wax) with silicone oil, hydrocarbon mixtures, and nano-particles to achieve both good workability and superior water-repellency. This composite approach allows the composition to exhibit properties that individual components cannot provide alone, resolving the contradiction between ease of application and water resistance performance.
Solution Approach 2:
The patent optimizes the proportion of each component within specific ranges (e.g., silicone oil at 0.1-40 parts, nano-particles at 1-200 parts per 100 parts of wax) to balance workability and water-repellency. By carefully controlling composition parameters, the formulation achieves both good applicability and high water resistance, resolving the performance contradiction.
2Reliability
If nano-particles are added to improve water-repellency, then contact angle is improved, but water-droplet rolling performance does not meet expectations
Solution Approach 1:
The patent combines nano-particles with silicone oil and specific hydrocarbon mixtures to create a composite surface treatment layer. This combination not only increases the contact angle for better water-repellency but also provides the lubricity needed for water droplets to roll off effectively, resolving the contradiction between static water resistance and dynamic rolling performance.
Solution Approach 2:
The nano-particles create localized hydrophobic regions on the surface while the silicone oil and hydrocarbon mixtures provide a continuous lubricating matrix. This local quality differentiation allows different areas of the coating to perform different functions: nano-particles for high contact angle and silicone oil for droplet mobility, thus resolving the rolling performance issue.
3Ease of operation
If temporary surface treatment film is formed, then ease of application is improved, but binding force with material surface is weak
Solution Approach 1:
The patent uses specific wax components (petroleum wax, beeswax, carnauba wax) with appropriate melting points and adhesive properties, combined with silicone oil and hydrocarbon mixtures, to achieve optimal balance between ease of application and binding strength. The composition parameters are optimized to ensure the film adheres sufficiently to the surface while remaining easy to apply, resolving the contradiction between application convenience and adhesion strength.
