Unit 1 Essential Question
How can Biologically Inspired Design be used with the Engineering Design Process to create unique solutions to problems?
Week 1 Overview
Learning Objectives
Students will examine existing products to discover the product requirements using the Four-Box method. Students will understand that engineers research prior and existing solutions to improve existing products and people’s evolving needs.

After identifying a problem, we must work to make sure we understand the problem (point to EDP Chart if printed out). This includes research to see if there are products that already address the problem and the needs of our user. These are called existing solutions. Engineers often analyze existing solutions 1) to understand how the current solutions work and 2) to understand if the existing solution is not fulfilling customer needs (and if so, why).

Today we will practice analyzing existing solutions to a variety of products using reverse engineering. Then, we will try to guess the requirements that the product was designed to fulfill. Requirements are a set of expectations our design/solution must have to make sure it fulfills the needs of the user and solves our problem.

Identifying requirements help us to make sure we understand the problem we are trying to solve so that we can actually solve the problem. Today we are going to practice deriving requirements from a variety of products before creating requirements for our “things that get dirty” problem tomorrow.

Teacher Note: Students will work in groups to examine Product Cards and complete the 1.1.3. Requirements Analysis - Product Organizer

Who are the users? Where is the product used?

What function(s) does the product perform?

What are the performance metrics?

What are the specifications?

Evaluate 15 min (Group-to-Group)

Now, your group will partner with another group to share individual products and requirements. Based on the comments of your peers, your team will revise your requirements.
