👉 Differential engineering is a design methodology that focuses on understanding and optimizing the behavior of mechanical systems by analyzing the differences in performance, efficiency, and functionality between two or more designed components or subsystems. It involves creating a detailed model that captures the dynamic interactions and responses of these elements under various conditions, allowing engineers to identify discrepancies and areas for improvement. By systematically addressing these differences, differential engineering aims to enhance overall system performance, reduce manufacturing costs, and improve reliability. This approach is particularly valuable in complex systems where the interaction between components can significantly impact the final product's effectiveness and durability.
