Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spacing between the ethylenically unsaturated group and the phosphate moiety in phosphate monomers is varied, then coating performance such as adhesion, corrosion resistance, and durability is improved, but the complexity of monomer structure design and formulation increases
Solution Approach 1:
The patent systematically varies the spacing parameter (number of atoms) between the ethylenically unsaturated group and phosphate moiety in the monomer structures. By changing this specific structural parameter, the invention optimizes coating performance including adhesion, corrosion resistance, and durability while maintaining a relatively simple monomer design approach.
Solution Approach 2:
The patent focuses on optimizing a specific local region of the monomer molecule - the spacing between the ethylenically unsaturated group and phosphate moiety. By concentrating the optimization effort on this critical local structural feature rather than redesigning the entire monomer, the invention achieves improved coating performance without excessive complexity.
2Reliability
If a specific molar ratio of monoester to diester monomers (at least 1.5:1) is used, then coating performance and substrate durability are enhanced, but the precision required in formulation and manufacturing increases
Solution Approach 1:
The patent specifies a particular parameter range for the molar ratio of monoester to diester monomers (at least 1.5:1). By defining this quantitative parameter, the invention achieves enhanced substrate durability while providing clear formulation guidelines that balance performance requirements with manufacturing feasibility.

AI summary
A curable composition is described, where the composition comprises, consists essentially of, or consists of a monomer of Formula (1) and a monomer of Formula (2), wherein a molar ratio of the monomer of Formula (1) to the monomer of Formula (2) is at least 1.5:1 and wherein the curable composition is substantially free of water. Also described is the cured composition, a substrate coated by the curable composition and a process for preparing the monomers of Formula (1) and Formula (2). The curable composition is useful to serve as a coating for a battery, especially for the external surface of a battery.
