What is Engineering Design? (Focused on Mechanical and Automotive Industries)
Engineering design is the fusion of scientific principles and creative thinking to develop products or systems. In the mechanical and automotive sectors, this process considers durability, energy efficiency, safety, cost-effectiveness, and aesthetics. It encompasses optimizing complex mechanical and dynamic systems, integrating innovative technologies, and enhancing production efficiency.
In the mechanical sector, engineering design focuses on developing industrial equipment, mechanical systems, and production tools. In the automotive sector, vehicle performance, aerodynamics, safety, ergonomics, and sustainability take center stage.
