AMI: Design process

Engineering Design Process

​

The Engineering Design Process

• Involves defining and solving problems or meeting needs 

• Must identify features that a successful solution must have

• Steps aren't always followed in order

Identifying Needs

• Engineering solution begins with a need

• May come from individuals, groups, or society

Open Ended

What do you think is a need from society? Why?

Define Engineering Problems 

• Criteria = features or qualities the solution should have

• Constraints = limitations that engineers face during the design process

Examples of Criteria

• Who needs the solution

• What the solution should do

• Ways the solution may affect society

Examples of Constraints

• Cost

• Time

• Resources

Multiple Choice

An engineer is designing a phone case and they want it to withstand a drop of 10 feet. Being able to withstand a drop of 10 feet would be a

• Criteria

• Constraint

Multiple Choice

An engineer is trying to design a phone case, but only has two months to do so. Having two months would be a

• Criteria

• Constraint

Poll

What do you think an engineer should do if their solution does not meet the criteria or constraints?

• Nothing, the solution should stay unchanged.

• Go back and modify the solution to better meet the criteria and constraints.

• Choose a different problem to solve that is not based on society's needs.

• Give up completely and forget about society's needs.

Imagine you were designing a house. What do you think a criteria (feature/quality) would be? What would a constraint (limitation) be?
