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 SAMEScientists seek to

UNDERSTAND WHAT IS, while Engineers seek to CREATE THAT WHICH

NEVER WAS- Theodore von Kármán, CalTech

Engineer Applied Scientist The First Laser Laser Sheet-Metal

Cutting Machine

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.

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 orteam 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 WiringSystem for a Buidling

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
