Good designers try to generate as many possible solutions as they can. Look at whether each possible solution meets your design requirements. Some solutions probably meet more requirements than others. Reject solutions that do not meet the requirements.

Development involves the refinement and improvement of a solution, and it continues throughout the design process, often even after a product ships to customers. A prototype is an operating version of a solution. Often it is made with different materials than the final version, and generally it is not as polished. Prototypes are a key step in the development of a final solution, allowing the designer to test how the solution will work. The design process involves multiple iterations and redesigns of your final solution.
You will likely test your solution, find new problems, make changes, and test new solutions before settling on a final design. Professional engineers always do the same, thoroughly documenting their solutions so that they can be manufactured and supported. What is the Engineering Design Process? Teacher Tool Box. Define the Problem The engineering design process starts when you ask the following questions about problems that you observe: What is the problem or need?
Who has the problem or need? Why is it important to solve? Do Background Research Learn from the experiences of others — this can help you find out about existing solutions to similar problems, and avoid mistakes that were made in the past. So, for an engineering design project, do background research in two major areas: Users or customers Existing solutions.
