Engineering design is the creative and systematic process of turning ideas into functional, practical, and safe solutions. It lies at the heart of engineering, serving as the bridge between concept and implementation, and it plays a pivotal role in shaping our world. Engineers conduct research to gather information and explore potential solutions. This phase involves examining existing designs, materials, and technologies. Engineers assess the generated concepts, weighing their feasibility, effectiveness, and potential impact. Evaluation criteria include technical, economic, and social factors. A prototype is a physical representation of the design. Engineers build prototypes to test and refine their ideas, identifying flaws and optimizing the design.
