Design and Technology

The document discusses approaches to design and technology. It defines technology as a system created by humans using knowledge and organization to produce objects and techniques for specific goals. Design is the process of converting an idea into information that can be used to make a product. Both engineering and industrial design are important in product development, with each discipline dominating depending on whether function or appearance is prioritized. The format that design information is conveyed in has evolved over time from informal drawings to formal blueprints to modern computer-aided design drawings.

Design and Technology

Unit 1 :Approaches to
design
Technology is one of the keywords
of our world, yet it is also one of the
most confused. As an analytical
category it seems necessary for our
understanding of all of humanity’s
history, and indeed beyond.
The word “Techne” is widely accepted
to mean “skill” and “art.” The
reconciliation of both interpretations
of the Greek word are facilitated by an
appeal to the logical connection that
exists between them: to create
anything requires skill and art. Both
skill and art may be considered as
metonyms for creation.
Technology is defined as “a system created
by humans that uses knowledge and
organization to produce objects and
techniques for the attainment of specific
goals”. Examples that currently exist, such
as the laser, the television, or the computer,
all qualify as technology according to the
criteria of this definition.

Design is the process of converting an idea


into information from which a product can
be made. From an engineering perspective,
the application of scientific concepts,
mathematics, and creativity to envision a
structure, a machine, system, or artifact
that performs a pre -specified function is
the definition of design.

mechanics of the arranged
parts, and

together

In designing a product, both form and


function are important, both disciplines
(engineering and industrial design) are
crucial in the development of the final
information from which a product can
be made.
The degree to which each discipline
dominates the design varies from product to
product. The design of a fighter plane is
going to depend more on the principles of
aerodynamics than on requirements of
appearance or what pleases the eye. The
design of fabric, on the other hand, is
dominated by needs of appearance.
The change in design process

The outcome of the design process is the information that can be


used to build it. The format of this information has changed over the
years.

Informal drawings :
In a primitive society, people designed things without being
conscious of the effort. Stone-Age tools, doors to mud dwellings,
and protection for the feet are examples of products that were
developed with no formal drawing or awareness of the design
process.
The change in design process


Formal blueprints:
Design by drawing or sketching existed
in some form or the other for more than
5000 years, it became more formalized
with time.

Design drawings :
The modern design process emerged with the
growth of the industrial society. Design by
drawing provided a designer much greater
flexibility to manipulate the design compared
to the pre-industrial society craftsmen. This
flexibility allows manipulation of the design
without incurring the high cost of building the
product then changing it. The design-by
drawing process, however, does not guarantee
success.

Drawings in electronic format
(computer-aided design(CAD)):
