As you look at the different dates in history and the corresponding phone pictures you'll realize that even though the function of the phone has not changed that much (before call waiting, answering machines, cordless, and cellular phones) there were still so many different styles and shapes.

This occurred so that the phone could continually meet the needs of the customers. The phone would change to become more comfortable, more aesthetically pleasing, and better functioning.

A big factor in the phone changes is the development of new materials. Different materials can cause a whole new design. Structure is closely linked to the materials that are used.

KEEP IN MIND AS YOU TRY TO FIGURE OUT A DIFFERENT MATERIAL TO USE THAT YOU MAY ALSO WANT TO THINK OF A NEW SHAPE OR STYLE THAT WILL BEST FIT THE NEW MATERIAL.
