Five critical goals of industrial designers while developing a product

1. utility: products human interface should be safe, easy to use and

intuitive.

2. Appearance: form, line, proportion and color3. Ease of maintenance and repair

4. Low cost: impact on tooling and production cost

5. Should reflect corporate design philosophy and mission

1. Ergonomic needs

-how important is ease of use?:fire extinguisher

-how important is ease of maintenance?: clear paper jam in printer-how many user interactions are required for the product functions?

More the no. of interactions more the need for ID ex. Door knob vs.

laptop

-how novel are the user interaction needs? incremental improvement

over existing design

-safety: childs toy

2. Aesthetic needs

- Is visual product differentiation required?: products with stable market

and technology.-how important is pride of ownership, image and fashion?

-will an aesthetic product motivate the team?

The impact of ID on Cost

1. Direct cost: no. and type of designers, duration of project

2. Manufacturing cost: less if ID is involved earlier in the PD process

3. Time cost: extended lead timeThe benefit of ID

1. Increased product appeal and greater customer satisfaction

2. translates into price premium and/or increased market share


9/11


How ID helps to establish a corporations identity.

A companys identity emerges primarily through what people see:

advertising, logos, signage, uniforms, buildings, packaging and product

design

The industrial design process

1. Investigation of customer needs

2. Conceptualization

3. Preliminary refinement

4. Further refinement and final concept selection

5. Control drawings

6. Coordination with engineering, manufacturing, and external vendors

Timing of ID involvement

-user driven products: identification of customer need in concept

development process-technology driven product: late in the concept development process
