![]() ![]() Ultimately, we want to design something that would help us if we were experiencing the same problem or need as our target population. This includes relating the project's problem or need to some aspect of our personal lives. ![]() So, your challenge would be to find out how to meet the requirement of receiving good grades under the given time constraints.īack to our engineering project - our final step today is to develop a project definition within each of our design teams. Although worthwhile, these time constraints may impinge on the amount of time you have to study. At the same time, you may be constrained by other activities such as work, sports, sleep, spending time with friends, and so on. For example, you may be required by your parents to receive good grades. A constraint is a restriction on the degree of freedom you have in providing a solution to a need or problem. A requirement is a need or a necessity it's what a particular product or service should do. Is the target population ultimately one individual, a group of individuals, a specific community, or a larger, identifiable population? Is the target population from a specific location (country, region, town), demographic (age or gender), or other identifying characteristics (health condition or employment)? How is our target population connected?Īfter we understand our project need and our target population, we will identify our project's requirements and constraints. ![]() Next, we want to identify our target population, which is the group of people who will benefit from our project. Instead of asking "what do we want to design?" we ask " why do we want to design that?" and "what problem and or need will our design ultimately be solving?" Who remembers all of the steps? The steps include: ask to identify the need and constraints, research the problem, imagine possible solutions, plan by selecting the most promising solution, create a prototype, test and evaluate the prototype, and improve and redesign as needed.įollowing this process, we start out by identifying the need for our engineering project. Remember, the engineering design process is a specific set of steps that engineers use to organize their ideas and refine potential solutions to engineering challenges. (Show the design loop graphic by overhead projection or handout.) First, let's review the engineering design loop. However, before we can dive into the design/build/test stages, let's take a start at the beginning and gather some information about the project. You will have a chance to get creative and work hands-on with a variety of materials. Today we are beginning an engineering design project! Similar to real-world engineering, our project requires strong teamwork, research, design, building, testing and communication. (Have an overhead transparency of the Engineering Design Loop Visual Aid ready to display in a prominent place in the classroom, or else make copies of the same graphic to use as handouts.) While these steps are not covered in this activity, a visual aid is provided for review. Optimize a design by addressing desired qualities within criteria and constraints.ĭefining the Problem Worksheet (pdf) Visit [ to print or download.Ī basic understanding of the steps of the engineering design loop.
