In the research phase of the engineering design process, engineers carry out an in-depth study of the project. This phase involves a thorough investigation to understand the problem from various sources like academic literature reviews, design consultations, and engineering design principles. The purpose of most design projects is to develop an object, structure, or process that meets the needs of customers and stakeholders. A customer is someone who will use the designed object; customers usually pay for the product.
Solving Everyday Problems Using the Engineering Design Cycle
Having chosen your approach, the next step is to refine and improve the solution to create a design proposal. This stage can be ongoing through the length of your project and even after a product has been delivered to customers. By researching past projects you can avoid the problems faced by others. You should speak to people from various backgrounds, including users or customers.
Ideas for a STEM Project
Students can use other materials to supplement the silk bridge, but have a $10 budget. Given scrap cardboard, paper towel tubes, scissors, and glue, how could a student invent their own backscratcher? Engage in the process of how real engineers design products to meet a desired function. These questions are in tune with the design specifications developed in substep B.2 – Specify Requirements. I feel that students should use their hands and maybe some tools (scissors, ruler).
EDP STEM Lesson Plans and Files (pdf files)
I recommend exploring short YouTube videos about product sketching by experienced industrial artists. For example, product design sketching master, Anton Ruckman, creates a photo camera with a blue pen. This tutorial is just over three minutes and the process is sped up. Fictional stories and historical contexts can serve as the PBL backdrop for STEM learning through EDP.
Summary of Step A – Analyze a Need
The final phase in the engineering design process is production. After this stage, the team launches the product in the market and it gets into the hands of end-users. Therefore, it is a critical stage as mistakes are not affordable and the stakes are high. Testing and evaluation may reveal weaknesses of the design or indicate ways in which the design may be improved. At this point, the design may be refined to better meet the criteria and constraints. Sometimes, testing and evaluation show that a design will not work, so that a different design concept must be selected; in this case, the process goes back to the “Select a design concept” step.

Student teams design, construct, test and improve small working models of water treatment plant processes to filter out contaminants and reclaim resources from simulated wastewater. They keep to a materials budget and earn money from reclaimed materials. They test them with flowing water, representing blood moving through the heart. Students learn about how biomedical engineers create assistive devices for persons with fine motor skill disabilities. They do this by designing, building and testing their own hand "gripper" prototypes that are able to grasp and lift a 200 ml cup of sand.
C.3 – Justify Changes to the Plan
To conclude, conduct the post-activity assessment described in the Assessment section to help students relate the project to some aspect of their own lives. This role-reversal exercise asks students to imagine they are members of the target population and develop three questions that they would ask the project engineers. A basic understanding of the steps of the engineering design loop. While these steps are not covered in this activity, a visual aid is provided for review. The prototype should be designed with cost-effectiveness in mind and can be made from different materials than the final product. It's also common to leave finishing touches off early prototypes so that you can concentrate on the overall concept.
C.1 – Plan the Build (and Maybe the Test)
The engineering design process provides a systematic approach to problem-solving, and best practices should be followed when designing products, systems, and infrastructure. Examples of engineering design can be seen in industries such as automotive design, aerospace design, civil engineering design, consumer product design, and environmental engineering design. By following the engineering design process and best practices, engineering design can create innovative and effective solutions to complex problems. The engineering design process involves making a series of decisions. Each decision must be carefully considered and justified based on various factors such as function, safety, cost, and feasibility. Throughout the process, engineers must weigh the benefits and drawbacks of different options and choose the best course of action based on their knowledge, experience, and the available resources.
This includes relating the project's problem or need to some aspect of our personal lives. Ultimately, we want to design something that would help us if we were experiencing the same problem or need as our target population. The final stage of the engineering design process is to share your results. You can create reports, presentations, and displays as needed to share the functionality of your product and why it's the best solution to the problem at hand. Since the process requires teams to often repeat steps multiple times, you may be concerned about the development phase being prolonged. However, the ability to identify potential issues early reduces overall project duration, as less time is spent on revisions later on.
Often there are existing solutions for problems we face if we just consider how to adapt them to our specific situations. Therefore, it’s good practice to conduct background research on your chosen problem and gather data from existing studies or experiments. Use your design proposal to make a prototype that will allow you to test how the final product will perform. Prototypes are often made from different materials than the final version and are generally finished to a lesser standard. The prototype is rigorously tested under various conditions to validate its functionality and performance.
This process is different from the Steps of the Scientific Method, which you may be more familiar with. If your project involves making observations and doing experiments, you should probably follow the Scientific Method. If your project involves designing, building, and testing something, you should probably follow the Engineering Design Process. If you still are not sure which process to follow, you should read Comparing the Engineering Design Process and the Scientific Method.
Students learn how biomedical engineers work with engineers and other professionals to develop dependable medical devices. Student teams brainstorm, sketch, design and create prototypes of suction pump protection devices to keep fluid from backing up and ruining the pump motors. Design and construct a bridge for a local city that will have a high strength-to-weight ratio and resist collapse.
