What is Industrial Design?

May-13

2

The Industrial Designers Society of America (IDSA)

defines Industrial Design as:

Industrial design (ID) is the professional service of creating and

developing concepts and specifications that optimize the function,

value and appearance of products and systems for the mutual benefit

of both user and manufacturer.

ID goals

May-13

3

Product utility -safe, easy to use, and intuitive

Appearance - form, line, proportion, and color

Communication of corporate image - through the visualquality

Ease of maintenance and repair

Low (mfg) costs

ID Importance to product design

May-13

4

Ergonomics needs

Ease of use

Ease of maintenance

User interaction with the product

Minimum knowledge of using it safety.

Aestheti cs needs

Amount of product differentiation required

The importance of pride of ownership, image.

Motivation to the design team (for their pride in product)


5/23

Product types from the ID point of view

May-13

5

Technology-driven products

Engineering or technical requirement is paramount

ID has little involvement

Extreme cases of Intel chips and GE engines

User-driven products

Usually there is a high degree of user interaction for these products.

The functionality and/or its aesthetic appeal are important

ID works closely with marketing and engineering throughout the

process.

Technology-driven products

During the later phases of product development

In concept generation for user interface

In concept testing for for customers for feedback.

In detailed design and refinement for packaging and marketing

User-driven products

Throughout the entire process

In need analysis for identifying customer needs.

In concept generation for creating multiple concepts

In concept testing for creating models

In system level design for refining promising concepts

IN detailed design for selecting final concept and coordinating eng-mfg.-marketing efforts.

Phase -1 : Identification of needs

Small size & weight = thin phone

Performance features:VGA camera, large keys with back lighting, color display withgraphics, Bluetooth for wireless headset

Ergonomics: good user comfort, buttons were designed based on accepted industry

standards, flip phone allowed answering or ending calls, new software for navigation, textmessaging

Durability :withstand 1 meter drop test

Materials :laser cut keypad, laser etching, magnesium hinge, anodized aluminum

housing, composite antenna

Appearance :futuristic look, became a status symbol, pride among owners
