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