The engineering process is a sequence of steps that engineers use to design functional products and processes. It is an iterative method that can be used to design prototypes or improve existing solutions. It’s also an excellent technique to improve your problem-solving capabilities and develop the “design under constraints” mentality. The engineering design process is a lot like the scientific method, however engineers use creativity and design.
Identify the Problem
Engineers first need to determine what the project needs to be successful. This requires a lot of thinking and the engineer must often consider limitations (e.g. In generating ideas for solutions, engineers must consider constraints (e.g., time materials, tools, and time). This step requires an engineer also to evaluate all possible solutions by identifying strengths and weaknesses, and then selecting the most suitable solution for achieving the objective of the project.
Generate Ideas
Engineers can select from a range of methods to generate solutions, ranging from brainstorming, discussions to 2D CAD modeling and animation. The solutions that are generated can be visualized and compared with the requirements of the issue to help find the best solution.
Now that the final solution is decided It is now time to create a model of the item. It could be as simple as a sketch on paper or as complex as a model that is constructed using the CAD software. This step gives engineers the chance to test the final product and determine if it is in line with the intended goals.
