Change over Time

Define the Problem

Analyze the evolution of a product and trace it from its beginning to its current use or end. Then select a product from a hobby or interest that has undergone noticeable improvements over some time period.

Develop a Design Proposal

Create a timeline and history of ClocksChange in Clocks Throughout

History◦A clock is an instrument used to

indicate, keep, and co-ordinate time◦“Clock" refers to any device for

measuring and displaying the time.

Develop a Design Proposal Early Clocks

◦Sun Dials – Used the movement

of the sun to move the shadow across the face of the clock

◦Water Clocks - Water clocks were among the earliest timekeepers that did not depend on the observation of celestial bodies

◦Sand Clocks - An hourglass (sandglass, sand timer, sand clock) measures the passage of a few minutes or an hour of time

Develop a Design Proposal

Pendulum and Spring Clocks◦ The pendulum clock was invented in

1656 by Dutch scientist Christiaan Huygens, and patented the following year.

◦ Earliest pendulum clocks used weights to power the clock

◦ Windup clocks have been around for nearly 400 years. When they were first invented, windup clocks were the most advanced machines of the time.

Develop a Design Proposal Modern Age - Digital and Quartz

◦Quartz - A quartz clock is a clock that uses an electronic oscillator that is regulated by a quartz crystal to keep time

◦ LED -A light-emitting diode, LEDs are used as indicator lamps in many devices, and are increasingly used for lighting

◦ LCD - A liquid crystal display (LCD) is a thin, flat electronic visual display that uses the light modulating properties of liquid crystals
