Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermosetting composite materials for sanitary articles like sinks and washbasins face challenges in balancing ease of cleaning, hydrophobicity, mechanical strength, resistance to impacts and temperature variations, and aesthetic appeal, often compromising one characteristic for the improvement of another.
Innovation Solution
A thermosetting composite material comprising a polymeric matrix with a mixture of isobornyl methacrylate, cyclohexyl methacrylate, and 2-hydroxyethyl methacrylate, along with a filler material combination of crystalline and amorphous inorganic particles, optimized for mechanical strength, scratch resistance, and thermal stability, while maintaining ease of cleaning and aesthetic quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If glass beads are used as filler material to improve ease of cleaning and hydrophobicity, then water absorption decreases and cleaning ease improves, but mechanical strength and resistance to impacts deteriorate
Solution Approach 1:
The patent uses a composite filler system combining glass beads (200-1500 μm) with mineral particles (0.1-2 mm) in specific proportions. The glass beads provide surface impermeabilization and ease of cleaning, while the mineral particles contribute to mechanical strength and impact resistance. This composite approach allows simultaneous achievement of both cleaning ease and mechanical strength that single-fillers cannot provide.
2Strength
If cross-linking agents are increased to improve scratch resistance and surface compactness, then surface hardness and scratch resistance improve, but elasticity and resistance to thermal shocks deteriorate
Solution Approach 1:
The patent optimizes the cross-linking agent content within a specific range (10-50% by weight with respect to total binding agents) and uses a combination of acrylic binding agents with different cross-linking densities. This parameter optimization ensures sufficient scratch resistance while maintaining adequate elasticity and thermal shock resistance by avoiding excessive cross-linking that would make the material too rigid.
3Ease of operation
If hydrophobicity is enhanced to improve ease of cleaning, then water repellency and cleaning efficiency improve, but adhesion and mechanical bonding deteriorate
Solution Approach 1:
The patent creates different surface properties through the filler distribution: glass beads concentrate at the surface level providing hydrophobicity and ease of cleaning, while the mineral particles and binding agents in the bulk material provide strong adhesion and mechanical bonding. This spatial differentiation of properties allows simultaneous achievement of both hydrophobicity and adhesion.
