What is Design?
Definition of design is not unique
Creating something new that never been donebefore.
Very broad meaning and practiced not only
by engineer but also artist, architect, songcomposer, etc.

To Design is:
to plan and fashion artistically or skillfully to intend for a definite purpose (Webster)
to create something the that has neverbeen
To design is to pull together something new orarrange existing things in a new way to satisfya recognized need (of society).

Industrial Design concerns with the overallphysical appearance of a product and consists
of many elements, the arrangement of which iscritical to the aesthetic and function of theproduct.

Unity:use of similar elements throughout thedesign, think of the product as a whole instead of
individual components. Style:addition of a decoration to a product, newstyles are created to generate consumer interest.
Mass:provides a sense of heaviness. Proportion:relationship between parts of a product.
Balance:it gives the product equilibrium. Contrast:it is used to emphasize or de-emphasize
certain elements in design.Color:used to evoke emotions

Design Philosophy
The Four Cs of Design
Creativity: Requires creation of somethingthat has not existed before or not existed in
the designers mind before. Complexity: Requires decisions on many
variables and parameters.
Choice:Requires making choices between many
possible solutions at all levels, from basicconcepts to smallest detail of shape.
Compromise: Requires balancing multiple andsometimes conflicting requirements.

Adaptive design: the designers work will beconcerned with adaptation of the existing of
existing design. No need special knowledge and skill in
design.Development design: The designer starts from
existing design but the final outcome may differmarkedly from initial product. Need scientific training and design ability.
New design: Only small number of designs arenew design.

Innovation Level in DesignBasically new inventions are rare although lucky breaks dooccur. The following are categories of innovation:
Simple innovation, for example, side steps on
minibus vehicles. Direct solution to a problem, for example, new
placement of brake lamps in order to be clearlyseen by the driver of the car behind.
Adaptation of an old principle to an old problemto achieve a new result, for example, GDI(Gasoline Direct Injection) technology used in thegasoline engine.

Application of new principles to a new use,
for example, the ABS(Anti-Lock Braking
System) used to improve car brakesperformance and GPS (Global PositioningSystem) for navigation.
Serendipity,a rare discovery that led to a
great invention, for example, the carinvention at the end of the 19th century andthe internet invention of the informationtechnology era.

Conceptual Design
Conceptual design is the process by which thedesign is initiated, carried out to the point of
creating a number of possible solutions andnarrowed down to a single best concept.
It is the phase of design which requires the
greatest creativity, involves the most uncertaintyand requires coordination among many functions inthe business organization.

Customer need identification: The goal of thisactivity is to completely understand the customers
need and to communicate them to the design team.
Problem definition: The goal of this activity is tocreate a statement that describes what has to be
accomplished to satisfy the needs of the customer.Problem definition produces a product designspecification (PDS).

Prototype: an approximation of the product alongone or more dimension aspects.
Prototype includes concept sketches, mathematicalmodels as well as fully functional preproductionversions of the product.
Prototyping is the process of developing suchapproximation of the product.
