The Engineering Clinic: A Four-Year Design Sequence

1
Engineering Design

• To create effective designs you must
• Recognize a need realize (potential) client
  expectations.
• Develop technical specifications.
• Generate multiple feasible designs.
• Choose the best solution.
• Evaluate your solution.

2
Example of Product Design
Eero Saarinen, architect Fred Severud, structural
engineer

• Stainless Steel
• 630 Feet Tall
• 630 Feet Wide
• Equilateral Triangle

3
Example of Process Design
MacDonald Construction Company

• Foundation 60 feet deep
• 42 Fabricated sections shipped on gondola cars
• Creeper derricks and vertical tracks built onto
  side of arch

ObjectivesWhat is Quality?

• After this presentation you will be able to
• Generate a list of customer attributes
  associated with a quality consumer product.
• Construct a House of Quality to determine how
  customer attributes map into a set of specific
  engineering characteristics.
• Develop a set of engineering specifications for
  a quality consumer product.

Quality. You know what it is, yet you don't
know what it is.  ...some things are better than
others, that is, they have more quality.  But
when you try to say what the quality is, apart
from the things that have it, there's nothing to
talk about.  But if you can't say what quality
is...how do you know that it even exists?  ...but
for all practical purposes it really does exist. 
Why else would people pay fortunes for some
things and throw others in the trash pile? 
Obviously some things are better than
others...but what's the "betterness"? ...What the
heck is quality?  What is it? Zen and the Art
of Motorcycle Maintenance Robert Pirsig, 1974

• Beauty is in the eye of the beholder
• In terms of quality, we can restate this as
  follows
• Quality is in the eye of the customer.
• Customer Attributes (CAs)
• What are the physical attributes that a customer
  might associate with a quality product?

Beauty is in the eye of the beholder In terms
of quality, we can restate this as
follows Quality is in the eye of the
customer. Customer Attributes (CAs) What are
the physical attributes that a customer might
associate with a quality product? Customer
Attributes are vague subjective vary with
individual based on personal values

Engineering CharacteristicsWhat is Quality?
Engineering Characteristics(ECs) What are the
engineering characteristics responsible for
creating the customer attributes associated with
a quality product. Engineering
Characteristics are specific technical can
either positively affect or negatively affect a
CA trade-off against one-another
