What is Engineering?
 Short Answer → Audience Suggestions first
 Technical Product Creation 
• The Output of ALL Engineering is
– The Solution to a Practical Problem
– Fulfillment of a Practical Need
• Long Answer → Technology Creation
Through the Application of the Quantitative
(Number-Based) Academic Disciplines
– Mathematics
– Sciences; e.g., Physics, Chemistry, Biology
– Empiricism (Experiments and Tests)

Engineering vs. Science
 Engineering is Closely Related to
Science & Math, but it is NOT the SAME
Scientists seek to
UNDERSTAND WHAT IS,
while Engineers seek to
CREATE THAT WHICH
NEVER WAS

Professor, and the Father of Modern
AeroSpace Engineering

Theodore Harold Maiman was born in 1927 in Los Angeles, son of an
electrical engineer. He studied engineering physics at Colorado
University, while repairing electrical appliances to pay for college, and then
obtained a Ph.D. in Physics from Stanford in 1955. Theodore Maiman
constructed this first laser in 1960 while working at Hughes Research
Laboratories (T.H. Maiman, "Stimulated optical radiation in ruby lasers",
Nature, 187, 493, 1960). There is a vertical chromium ion doped ruby rod in
the center of a helical xenon flash tube. The ruby rod has mirrored ends.
The xenon flash provides optical pumping of the chromium ions in the ruby
rod. The output is a pulse of red laser light.

Engineers take BASIC
Scientific Discoveries and turn
them into things that are
USEFUL to people. In that role,
Engineers are the agents of

Design is the Pinnacle
 The GREATEST Accomplishment in the
Engineering Profession → Design of a
SUCCESSFUL Product
 There are NO Right or Wrong Solutions
to a Design Problem
• There are only Successful & UNsuccessful
Solutions → Largely the result of Creativity
 In my ENGR11 Design Class: I can’t
define a Successful Design, but I know
one when I see one…

WHAT do I DO in the Classroom?
 This, ITSELF, is a DESIGN PROBLEM
• Develop DESIGN PROJECTS that Must
– Involve Applied Science
– Be Age Appropriate (Very Difficult Constraint)
– Be Inexpensive; $0 to Design, 20$ to Build
– Be of 4-16 weeks duration
– Be Carefully DOCUMENTED SomeHow
 A Documentation-Set is the Ultimate OUTPUT of
Design Engineering as required by Practicality
• The Design Project may be individual or
team Based (too much emphasis on teams)

Design → OPEN Ended Problem
 In my ENGR11 Design Class: I can’t
define a Successful Design, but I know
one when I see one…
 Two Major Types of Engineering Design
• Clean Sheet - No Constraints other than
$’s & time
– Example (Circa 1950): Design a Random
Access Computer Memory → Result ≡ HDD’s
• Technology (Code) Constrained
– Example: Design the Electrical Power Wiring

Design: Engineering vs Industrial
 Engineering Design MUST Include an
applied-SCIENCE Component
 Design Engineering is NOT
• “Tinkering” → Intuitive “Cut & Try”
– “Intuition is often WRONG
• INDUSTRIAL Design → Focus
is on “Form”, or “Curb Appeal”
– Industrial Design Goal → Make it LOOK Cool
– Engineering Design Goal →
Make it WORK Cool

WHAT do I DO in the Classroom?
 An Easy One to Start: Dissection &
Documentation
• a.k.a., “Reverse Engineering (Design)”
• Students Disassemble a common object
(e.g. a power screw driver) to
– Understand how the major components interact
– Document the parts
 Locate Part numbers
 Count Quantities
 Use Tools
 Loose Fear of the Physical
