how to write a case study?

I’m a student and need to write a few case studies to apply for an internship, but I don’t know what to include.

Also, how should I approach a case study where the design is only styling, not solving a functional or human factors problem?

Thanks in advance!

Talk about the thought process behind the styling. Do the forms mean anything, where did the inspiration come from, how does it relate to the product. Many designers use metaphors or meaning behind the shapes and forms and details thay use.

thanks! that helps, but is there a format, or other things I should include?

Format should be the process. What was the initial problem or brief. Then what did you do and where did you draw inspiration from to create the design. Then talk about the implementation on how you solved or resolved or addressed the initial brief and goal.

thank you everyone!
