Components in Products
• Some products are a single
components (nail, bolt, fork, coat
hanger, etc.)
• Some products are assemblies of
many components (ball point pens,
automobiles, washing machines, etc.)
• All components are manufactured.
• Manufacturing means, literally, “Made
by Hand”.

Materials Selection for Paper Clips
Questions for consideration:
• What material properties are
required?
• What manufacturing attributes are
required?
• Would the material and processing
strategy change if the desired
quantity was 10,000 vs. 1 million
per day?
Figure I.2 Examples of the wide variety of materials and geometries for paper clips.

Product Design Process
Figure I.4 (a) Chart showing the
various steps involved in design
and manufacturing a product.
Depending on the complexity of
the product and the type of
materials used, the time span
between the original concept and
the marketing of the product may
range from a few months to many
years.
(b) Chart showing general
product flow in concurrent
engineering, from market analysis
to selling the product. Source:
