Engineering Design Process

​What is the Engineering Design Process?

A step-by-step approach used to ​find a solution to a need.

1. Identify the NEED (problem), CRITERIA (things the solution must have) and CONSTRAINTS (limitations that will make designing the solution difficult).

2. ​Brainstorm multiple possible solutions for the problem.

3. ​Choose the most promising solution and build a PROTOTYPE (rough draft of the solution used to prove the idea will work like it is supposed to.

​What is the Engineering Design Process?

​​4. Test the prototype and get FEEDBACK (information about the PROS (good things) and CONS (bad things) of the design.

​5. ITERATE (repeat steps 2-4 to modify and improve the design. Continue iterating until a satisfactory solution is found.

​6. Communicate the results of the solution to others. The more people who have access to your solution, the better!

Multiple Choice

Which of the following best describes the NEED?

• Pizza crust has gluten

• Your friends arrive in 30minutes.

• One of your friends can't eat gluten

• You are hungry

Multiple Choice

Which of the following is a CRITERIA?

• Must be able to feed you and your friends

• Can't contain gluten

• Friends arrive in 30 minutes

• You only have 5 dollars

Multiple Choice

Which of the following is a CONSTRAINT?

• Everyone likes tacos

• You don't have any spices

• Corn chips are gluten free

• You have peanut butter and jelly

Multiple Choice

The step where you identify many different possible ideas to solve the problem is called:

• Identifying the need

• Brainstorming

• Building the prototype

• Feedback

Multiple Choice

The step where you first build the design

• Rough draft

• Feedback

• Prototype

• Brainstorm

Multiple Choice

Information gained by testing the prototype

• Feedback

• Results

• Conclusion

• Need

Multiple Choice

The engineering design process is said to be "iterative" because

• It is difficult

• It is a set procedure

• It always starts with a need

• It is repeated many times until a solution is found

Multiple Choice

Which of the following is the worst way to communicate results?

• Post the results online

• Publish the results in a magazine

• Market and sell your design solution

• Tell a friend

​Design Criteria and Constraints

​Criteria (Design must):

• ​Prevent egg from cracking

• ​Land on crash pad tarp

• ​Be as cost effective as possible

• ​Each iteration must be built and tested in one class period.

​Constraints (Design can't):

• ​Use any outside materials

• ​Cost more than $25

• ​Only 3 iterations allowed
