Product Development

The economic success of industrial factories

depends on their ability to identify the needsof customer and to quickly products that meetthese needs and can be produced at low cost.

Design Philosophy

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.


28/64

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 DesignDesign Philosophy

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.

What is Industrial Design?


36/64

UniversitiKuala


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

Also known as Engineering Design

Focuses on function on the product instead of

Design Philosophy

What is Engineering Design?

A systematic, intelligent generation andevaluation of specifications for products whoseform and function achieve stated objectivesand satisfy specified constraints.

Create a component, system or process thatcan perform a specific duty optimally andsubject to certain constrains.

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.


45/64

UniversitiKuala


teDesign Level

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.


47/64

UniversitiKuala


te

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.

Mechatronics systems or products are varied, fromvery simple devices up to very complex ones such ascars, trains and airplanes.

The major drawback of the design-by-disciplineapproach is that fixing the design at variouspoint in sequence causes new constraint,resulting from the design at that point; to becreated and passed on the next discipline?

Mechatronics design approach is based on concurrent,instead of sequential, approach to discipline design,resulting in product with more synergy.

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.

Conceptual Design

The following are the discrete activities that weconsidered under conceptual design: Customer need identification Problem definition Gathering Information Concept generation

Concept selection

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).

Concept generation: It is involved with creating abroad set of concepts that potentially satisfy the

problem statement.

Concept selection: Evaluation of the generatedconcept, modifying and evolving into a single

preferred concept.

Embodiment Design

Embodiment design also called as preliminary designis the place where flesh is placed on the skeleton

of the design concept.

Beyond this design phase major changes become

very expensive.

Embodiment Design

Product architecture: PA is concerned with divingthe overall design system into subsystems pr

modules. In this step it is decided how the physicalcomponents of the design are to be arranged andcombined to carry out the functional duty.

Configuration design: Configuring parts andelements.

Mechatronic Design ApproachPrototyping

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.
