Introduction

• Early prototype built by Greeks around 250 B.C.
• First mechanical clocks were massive and made in
  14th century.
• Early alarm clocks were found in Germany in the
  early 15th century.
• Alarm clocks became popular in late 1870s.

Electrical Engineering

• Power supply battery or 120V of AC power from
  wall socket
• Generates a 60 Hz signal
• Screen shows a typical LED seven-segment display

4
Electrical Components

• Capacitors
• Resistors
• Transistors
• IFT and OSC coil
• Tuning Capacitor
• Integrated circuit (IC) chip
• Loopstick Antenna
• etc

5
Mechanical Engineering

• Hard plastic casing
• Controls located at the top of the clock
• Antenna for radio located internally
• Speaker located at top of the clock

6
Industrial Engineering

• The alarm clock fits all expected needs,
• such as an ability to waking the user,
• easy usage, power cord, etc.
• Performance needs are met with cheap
• cost, visibility in the dark, reliability,
• Durability, etc.
• There are no exciting functions of the
• alarm clock to mention. This is a basic
• cheap model, with basic functions.
• Business prospects show that the clock
• would create a positive income and would
• be worthwhile producing.

Conclusion

• The purpose of a clock has been to tell time
• There have been many way to tell times over the
  course of human history.
• From Egyptian shadow clocks to Chinese water
  clocks.From basic to digital
• The alarm clock forcefully tells time, and as
  such its most convenient way, is by our beds.

...

• We have been able to deconstruct a simple alarm
  clock.
• In order to think of new way to engineer a better
  product for the future.
• Taking into account costs, safety, parts,
  electronics, materials, design and consumer
  benefit.
• There will always be a market for scheduled alarm
  signals.

The Future

• The future is always smaller. Compact
• Personal use
• Future possibilities for the alarm clock lie in
  touch screen as with popular technology.
• A smaller design with easy user access, edit and
  input.
• Rather than a Repeated buzzing as a reminder of
  the past. We can opt for enjoyable music for a
  brighter tomorrow.
