What is made during the generation of ideas phase in the engineering design process?

During the generation of ideas phase in the engineering design process, conceptual sketches are created as a means to visually represent and explore potential solutions to a given problem. This phase is crucial for brainstorming and allows designers to think creatively and express their ideas in a tangible format. Conceptual sketches serve several important functions: they help in visualizing concepts, facilitating communication among team members, and allowing for quick modifications based on feedback and further idea development.

In contrast, prototypes, testing strategies, and final solutions are developed in later stages of the design process. Prototypes are physical representations created after ideas have been fleshed out and are intended for testing and validation. Testing strategies come into play once prototypes are available, aiming to evaluate the effectiveness of the design. Final solutions are the end products that emerge from the comprehensive design process following multiple iterations and refinements of initial ideas. Hence, conceptual sketches are uniquely aligned with the exploratory nature of the idea generation phase.
