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
