INTEGRATING SCIENCE, TECHNOLOGY, ENGINEERING AND MATHEMATICS (STEM) INTO THE HOME ENVIRONMENT

Trendy Tennies

ENGINEERING TASK

You have been asked by a popular shoe company to design a new trendy tennis shoe for unique needs of their four customers. Pick one of the customers and design a tennis shoe to meet their needs. You decide to use everyday products to construct the tennis shoe prototype.

CUSTOMER 1—OLAF

Age: 3 (Frozen 2)
Shoe size: Kid’s 3
About: Olaf has a layer of permafrost to keep him from melting. He enjoys riding Sven and hanging out with Else in Arendelle.

CUSTOMER 2—SERENA WILLIAMS

Age: 39
Shoe size: Women’s 10.5
About: Serena is an American professional tennis player and has won 23 Grand Slam singles titles.

CUSTOMER 3—HULK/BRUCE BANNER

Age: 49
Shoe size: Unknown; feet change sizes
About: Bruce is a brilliant scientist. As Hulk, he has unlimited superhuman power, can leap great distances, and can heal injuries within seconds.

We also encourage you to use materials and tools in and/or around your home environment.

PROTOTYPE

Prototype is a term we will use often, so what does it mean? One way to think of a prototype is a rough draft on a paper. Here are two videos that explain a prototype in engineering.

STEP 1—RESEARCH

Let’s do research on the customer or user you selected as we want to design an appropriate shoe. As you search and find interesting things about your customer, be sure to write them down.

Next think about how you will use the information about your customer in the design of the shoe. For example, what is the intended purpose (e.g., running)? How will you make your prototype uniquely stylish, a one-of-a-kind design?

STEP 1—RESEARCH

Below is another place to learn more about the design of the shoe such as the thickness of the sole or bottom of the shoe.

Additional shoe design elements for you to research may include (a) flexibility, (b) traction, and (c) ankle support.

STEP 2—PLAN

On a sheet of paper, sketch your shoe design and list the material you will use for your prototype shoe. You are free to use the material in the kit and/or material in your home.

It is okay to ask others to also sketch a design.

STEP 3—TRACE

Trace someone’s foot to use in your design. Next, estimate the length of the foot print in inches.

STEP 4

Create and test your prototype.

STEP 5—IMPROVE

How would your customer rate your prototype?

Based on your customer and your research, what changes and/or additions might you make to improve your prototype? Explain why. Continue to redesign the prototype until you get a 5-star rating.

DID YOU KNOW?

Biomechanical engineers are involved in designing shoes and other products such as backpacks and child safety car seats. They must understand the mechanics of how our bodies move to design products that are comfortable, safe, and enhance human performance. Check out https://youtu.be/Pu0lp7apU1Y
