engineering design Process

#3

Multiple Choice

Engineers are people who....

• Solve Problems

• Design and Build new Things

• Work Together

• All of these things!

What is the engineering design

Process?

• The design process is a purposeful

method of planning practical solutions to
problems.

• The design process is never final; there

are always multiple solutions to a problem.

• The design process is influenced by

requirements called criteria and
constraints.

Multiple Choice

Engineers follow the Engineering Design Process

• True

• False

What is engineering design?

• engineering design is a

creative planning process
that leads to useful
products and systems.

• There is no perfect design.

• Requirements of a design

are made up of criteria and
constraints.

Multiple Choice

The first step of the Engineering Design Process is to:

• Build

• Eat a pancake

• Ask

• Take a nap

What is the most important step?

Multiple Choice

After we Ask, the next step is to:

• Watch a youtube video

• Imagine

• Improve

• Have a dance party

The adopted GTT design
process combines
several steps.

What steps are combined?

Multiple Choice

After we Imagine, we can start to:

• Plan

• Ask

• Find a partner to help

• Play outside

Defining the problem is like
conducting detective work. You
must examine the evidence and
form some
conclusions.

Examples:

engineering design a vehicle that can
communicate with other vehicles to prevent
accidents.

engineering design an athletic shoe that
decreases the amount of sprained ankles when
worn on hardwood gym floors.

Why is it important to

Brainstorm?

Brainstorming involves
bringing a group of people
together to generate many
different ideas.

Examples:

“Make the athletic shoe out of plastic.”

“The shoe needs to grip the floor; the
bottom should be made of rubber.”

“The ankle support should be stiff.”

“Don’t forget the air vents.”

All ideas are considered important–
none are criticized!

What is your way to

Research?
Research may require going to the
library, using computer databases,
writing letters, performing
experiments, and asking questions.

Multiple Choice

After we have our plan, it is time to:

• Create

• imagine

• Have a second pancake

• Draw Spongebob

Are there too many

ideas?
Develop multiple ideas that will
solve the problem and meet the
requirements. The alternatives
may all be quite diverse.

Criteria:

✔ What should the product look like so

that people will buy it?

Constraints:

✔ Will it be completed by the deadline?

✔ What size should it be?

How do you choose

the Best Idea?
Decide on an idea that best meets the
criteria, fits within the constraints, and
has the least amount of negative
characteristics.

List the strengths and weaknesses of
each alternative.

Optimization – Making improvements
to the design idea for better
performance or increased safety

Trade-off – Giving up one desirable
trait for another (i.e., giving up on using
a certain material so that the object is
more affordable)

What is a Prototype?

Model building is used to gather
additional information and test
design ideas.

Examples:

Realistic drawings or renderings help you
visualize what the solution will look like in real
life.

Scale models or mock-ups are small,
accurate representations of the final product.

3D CAD (computer aided designs) can show
objects in action.

A prototype is a working model; it looks and
functions just like the finished product.

Multiple Choice

Now that we have created our first attempt, its time to:

• Improve

• Plan

• Take your dog for a walk

• Do chores

How do you
Evaluate?
Models of design solutions must
be tested and important
questions must be answered
during the evaluation.

Is it safe for people and the environment?

Is it comfortable?

Is it affordable?

Is it aesthetically pleasing (does it look
good)?

Will it last as long as it needs to?

Does it meet the criteria and constraints?

Does it work?

What do you do after

testing your idea?

After studying all test data and
evaluating design solutions, you
may need to make changes.

Now is the time to improve a design –
before production begins.

During the improve design phase, you
may consider new ideas.

What is your favorite

way to share your

results?
Share your design ideas with
others to prove the design is
worthy of manufacturing.
