What is Engineering?
Meeting today’s challenges and creating tomorrow’s future by practically applying
scientific knowledge.
Isn’t engineering the same thing as science?No!!
Engineering
Using technological and scientific knowledge to solve practical
problems.
ScienceThe study of our natural world through observation, identification, description,
experimental investigation and theoretical explanations.
Discovers The World That Exists.
Creates The World That Never Was.
-Theodore Von Karman
EngineersPeople who
are trained in and use
technological and scientific knowledge to solve practical
problems.
What is Engineering?Using technological and scientific knowledge…
Science explains how
a magnet works.
What is Engineering?…to solve practical problems.
Engineering uses a magnet to be able to
see inside the human body.
What is Engineering?Using technological and scientific knowledge…
Science explains how
we can capture images on a
camera.
What is Engineering?…to solve practical problems.
Engineering creates a pill that has a camera to take pictures of
the human digestive tract.
What is Engineering?…to solve practical problems.
Engineering created a table
saw that can cut through wood, yet
will stop immediately if it hits human flesh.

What is an Engineering Technician?
A worker that is highly trained to perform specific tasks and generally
follow procedures developed by engineers.
What’s the difference?
• 4-5 year Bachelor’s Degree
• $70,000-$100,000 average salary
• Designs, Invents, Improves- Supervisor
Engineer Engineering Technician
• 2 year Associate’s Degree
• $45,000 - $60,000 average salary
• Hands-on; Works for an Engineer
What is an Artisan?
A skilled manual worker • Artisans do primarily hands-on work.• Artisans are usually paid hourly; not
by salary.• Artisans follow procedures and plans
designed by engineers.
Ergonomics
How humans interact with man-made objects. The goal of
ergonomics is to create and environment that is well-suited
to a user’s physical needs.
Footprint
The area covered by something, such as
machinery or equipment
Engineers Design Solutions
What does design mean?
-to create a plan for the construction of an object or a
system; invent
Engineers Follow A Process
The Engineering Design Process is a step-by-step problem-solving strategy, with criteria and constraints, used to develop many possible solutions and
then choose the best one.
The Engineering Design Process
Step 1- ASK
What is the problem?What exactly are you being
asked to do?
Step 1- ASK
What are the requirements?
What MUST your solution do?(Be a certain size? Hold a certain
amount of weight?)
Step 1- ASKWhat are the constraints?
A constraint is a limit to the design process. It may be things
such as appearance, funding, space, material, and/or human
capabilities.
Step 2- IMAGINE
Brainstorm IdeasBrainstorming is a method of
shared problem solving in which all members of the group
spontaneously generate ideas in an unrestricted discussion
Step 2- IMAGINEChoose the Best IdeaDiscuss your ideas. Determine if they meet the requirements and constraints. Then use a Decision Matrix to compare each idea and
decide which one is the best.
Decision Matrix
A tool for systematically ranking alternatives
according to a specific set of criteria
Option-List the things that are good about this design.
List the things that are not so good about this design.
Design Matrix
Option 1- A tripodList the things that are good about this design.
• Uses less paper
List the things that are not so good about this design.• Hard to balance the
book on top• Legs might slide
apart
Example Design MatrixPaper Table Challenge
Option 2- Four Tubes- one at each cornerList the things that are good about this design.
• Will support the book evenly
• Shouldn’t slide apart
List the things that are not so good about this design.• Uses more paper
Example Design MatrixPaper Table Challenge
Step 3- PLANDraw Your Design
Create a detailed drawing that clearly shows what your solution will
look like. This should include the exact criteria for your design.
Criteria
Criteria is the desired specifications(elements or features) of a product or
system.
Step 3- PLAN
Gather Your MaterialsMake sure you have everything
you will need to create your design.
Step 4- CREATE
Follow Your PlanUse your drawings and materials to actually build, create, prepare,
etc. your design.
Step 4- CREATE
Test It OutTry it and analyze the outcome.
Analyze
Analyze means to examine carefully and in
detail so as to identify causes, key factors, possible results, etc.
Step 5- IMPROVEDoes it meet the requirements?
If not, begin the process again to find a solution to this problem. If
so, begin the process again to make it better.
Step 5- IMPROVEDoes it meet the
constraints?If not, begin the process again to find a solution to this problem. If
so, begin the process again to make it better.
Step 5- IMPROVEWhat changes can you make to improve your
design?Engineers are ALWAYS trying to improve their design! They are
NEVER “Finished!”
