The technological world 1. The design process and the specifications

The Design Process Three phase : Design Production Marketing

Design No Yes Identify a need Analyze the technological problem Has the problem already been solved Write a set of specification Prepare a design plan Make a technical drawing Manufacture a prototype Test the prototype : Does it meet specifications? Apply for a patent No Yes

Production Prepare a manufacturing process sheet Prepare a flow-process grid Manufacture de product Write an instruction manual and maintenance manual Production

Discard or recycle the product Market the product Maintain de product Discard or recycle the product Marketing

Perspective The physical perspective The technical perspective The economic perspective The industrial perspective The human perspective The environmental perspective

The physical perspective Concerns all the natural elements ( air, water, earth) Example : Exposed to rain = rust This Photo by Unknown Author is licensed under CC BY-SA

The technical perspective Factors that affect the operation of the object Example : Maximum speed of the bicycle How long the batterie last

The economic perspective All cost the designer has to take into account ( production cost, selling price and maintenance costs) This Photo by Unknown Author is licensed under CC BY-SA

The industrial perspective Everything about industry : Where is it manufactured The production facilities The tools The work force The completion deadline This Photo by Unknown Author is licensed under CC BY-SA

The human perspective The people who will use it, maintain and repair the product. Example : The object is liked, easy to maintain. Aesthetics, safety and comfort

The environmental perspective Concerns the effects on the environment. Example : Less pollution Recyclable This Photo by Unknown Author is licensed under CC BY-NC-ND
