Criteria & Constraints

The engineering process begins...

• when a team brainstorms new ideas.

• when a team identifies the need or solution to a problem.

• when a team develops a prototype.

• when a team makes iterations to their prototype.

• option

• standard

• opportunity

• restriction

Which describes the "Define the Problem" part of the Engineering Design Process?

• Identification occurs when someone realizes that a problem exists that needs to be solved.

• Definition occurs when someone realizes exactly what the problem is and the requirements the solution must meet.

• the requirements the solution must meet, such as what it must do.

• the limitations on the solution, such as a maximum size or budget.​

Which describes the "improving" part of the Engineering Design Process?

• by thinking of possible solutions to the problem.

• considering the pros and cons of the possible solutions.​

• by trying them out to see how well they work.​

• thinking of ways the design could be better. ​

One day in November, Marisol opened her locker and had to quickly jump back to avoid the cascade of her belongings falling to the floor. “Oh no,” she yelled. “This isn’t cool!” Marisol quickly began to scoop her things back into her locker, but after putting everything away, she was late to her next class. Unfortunately, this wasn’t the first time the locker avalanche had happened. “I’ve got to find a way to organize my locker,” she said to herself. What stage of the Engineering Design Process is this?

• Identifying/Defining a Problem

• Developing Ideas

• Evaluating Ideas

• Criteria/Constraint

In order to generate possible ideas for her own locker, Marisol used her smartphone to take photographs of her friends’ lockers—or at least photographs of those that were organized. She would have to make an organizer herself. Since her parents only gave her a few dollars a week for allowance, she’d have to make an organizer for less than $3. This would describe what part of the engineering design process?

• The constraints

• The criteria

• Developing Ideas

• Evaluating Ideas
