Transcript Warm Up

Warm Up
On the notecards on your table, complete the
following;
1. List the different forms of Transportation
Technology.
2. List the four key components of flight.
3. Convert 10.28 cm to inches
The Engineering
Design Process
From Problem to Solution
Objectives
Students will be able to;
• Develop abilities to apply and analyze the design process.
• Identify a problem, and develop a process in order to solve it.
• Identify criteria and constraints and determine how these will affect the
design process.
• Identify and list the 12 steps of the design process.
THE
BIG PICTURE
What is Engineering?
Engineering is the discipline, skill, and profession of applying
science, math, social, and practical knowledge in order to meet
the desires and needs of people.
Breakdown
Your table will be given a set of items with different steps of the problem
solving process.
With your table, organize the steps in the order you feel an Engineer would
go through to solve a problem.
Be Prepared to defend your sequence of steps. You have 3 minutes to
discuss and order your steps.
Is That Right?
How did you do?
What order did you put the steps?

How do you know if a problem exists?
EXPLORE IDEAS!
Failure is an Option!
If you design fails, don’t give up! Re-Design and keep on trying,
giving up is never an option!

Our Problem
Solving Process
Design Process Breakdown
1. Define the Problem
The Engineer must determine
what the problem is that needs
to be solved.
Cable Car Example
• You must build a cable
supported car that will
traverse 15 feet along the
line as quickly as possible,
while holding a passenger.
Design Process Breakdown
2. Brainstorm Ideas
Brainstorm Ideas! This step
typically involves making a
mind map, a list and possible
thumbnail sketches.
Cable Car Example
• Create a small box and use
the balloon to push it
forward
• Make a rubber-band
powered car
• Origami style box, straw
attaches to cable…
Design Process Breakdown
3. Research & Generate Ideas
Research possible solutions
and see if something similar
has been created.
Cable Car Example
• Style like a current ski-lift
• Use the dome shape design
that can be attached to a
cable…
Design Process Breakdown
4. Identify Criteria &
Constraints
Find out any rules and
restrictions the design has.
What is required in it? What is
the time restraint?
Cable Car Example
• Must only use the given
resources
• Must travel 15 feet
• Passenger must not fall
Design Process Breakdown
5. Explore Possibilities
Rate different ideas using a
decision matrix to determine
which is the best solution.

engineer selects the highest
rated design.

Design Process Breakdown
7. Develop a Design
The engineer will sketch a
multiview drawing of their
chosen solution.
Cable Car Example
Design Process Breakdown
8. Develop a Prototype
Using the sketches, create a
scaled model or prototype of
the design.
Cable Car Example
Design Process Breakdown
9. Test and Evaluate
Test your prototype and
analyze the outcome of the
test.
Cable Car Example
Design Process Breakdown
10. Re-Design
If needed, re-design the
product in order to solve the
solution more effectively.
Cable Car Example
Design Process Breakdown
11. Create or Make the Final
Design
Make the full scale version of
the solution.
Cable Car Example
Design Process Breakdown
12. Communicate Results
The engineer will communicate
the results of their product to
peers or clients.
Cable Car Example
Design Time
You are to create a poster showing
how the design process works.
• Come up with a problem to solve
(e.g. I need to create a device that will feed
my dog.)
• Explain and Illustrate each step of
the design process.
• Your poster should be neatly
drawn and colored.
Review
If I am making a multiview drawing of a design, which step am I doing?
Develop a Design
Which step of the design process involves making a mind map or a list?
Brainstorming
Which two steps of the design process use a decision matrix?
