Which stage of the engineering design process involves exploring designs that have been previously created by others?

The stage of the engineering design process that involves exploring designs created by others is the research phase. In this phase, engineers gather existing data, previous work, and relevant literature to inform their current project. This research helps to identify established solutions, understand existing technologies, and avoid reinventing the wheel. By reviewing what has already been done, engineers can build upon previous innovations and learn from past successes and failures. This foundational knowledge is crucial for generating new ideas and refining design concepts.

During the research stage, engineers often look into case studies, patents, academic articles, and design benchmarks, which provide vital insights into what has been done in similar projects. This understanding of existing designs enhances creativity and informs decision-making in later stages of the design process.
