ENGINEERING DESIGN
ENGINEERING
“The art of directing the great sources of power in nature
for the use and convenience of man.”
“The science-based profession by which the physical
forces of nature and the properties of matter are made
useful to mankind in the form of structures, machines,
and other products or processes at a reasonable
expenditure of time and money.”
“The application of scientific and mathematical
principles to practical ends such as the design,
manufacture, and operation of efficient and economical
structures, machines, processes, and systems.”
ENGINEERING
Hoover Dam. It took nearly
500 workers 4 1/2 years,
working 24-hour-a-day
shifts, to build in the 1930's.
NASA¹s fourth space shuttle,
the Atlantis made its maiden
flight on October 3, 1985.
ENGINEERING METHOD
“The use of heuristics to cause the best
change in a poorly understood situation
within the available resources.”
Heuristics- anything that provides a
plausible aid or direction in the solution of
a problem.
“The heuristic-based reasoning used by
engineers is a universal method for
problem solving."
CONCEPTUAL DESIGN
“Conceptual design is just like it soundsthe generation of a concept.”
Concept- 1. A general idea derived or
inferred from specific instances or
occurrences. 2. Something formed in the
mind; a thought or notion. idea. 3. A
scheme; a plan:
lunar orbit rendezvous
NASA engineer John Houbolt explains how men would
get to the moon and back using "lunar orbit rendezvous." Houbolt
pushed NASA hard for the concept and its adoption in 1962 laid
the groundwork for success 7 years later.
ANALYTICAL DESIGN
Analytical design
examines each
component within a
system to ensure that it is
optimized.
Analyze- To examine
methodically by
separating into parts and
studying their
interrelations.
Mathematical and
modeling tools are used
to help eliminate
expensive prototyping.
