Preliminary Design is the initial phase in the design process where concepts and ideas are developed into a more structured format. This stage involves creating sketches, models, or prototypes to visualize how the final product will look and function. It helps identify potential challenges and opportunities early on, allowing for adjustments before moving forward. During this phase, designers consider various factors such as materials, costs, and user needs. Collaboration among team members, including engineers and stakeholders, is crucial to ensure that the design aligns with project goals. This groundwork sets the stage for more detailed design work in subsequent phases.
