Sample answer
“In designing a switch coupler for high-speed rail, I prioritize material selection to ensure it can withstand high loads and environmental conditions. For instance, using high-strength steel minimizes deformation. I conduct thorough load calculations and stress analysis, ensuring compliance with Chinese railway standards. Additionally, I focus on designing for easy maintenance, which reduces downtime. During my previous project, we successfully implemented a new coupler design that increased reliability by 30%.”
