The document discusses solving the problem of short battery lifespan in common watches. It aims to increase battery lifespan to reduce e-waste and save money on battery replacement. The root cause is identified as the limited storage of electricity in coin batteries. Potential solutions proposed include powering watches with piezoelectric batteries that can recharge through vibration or incorporating additional safety features.

2. The Problem Statement
Common watches in the consumer market are
found to be consisting problems such as
•Short battery lifespan
•Used of battery increase the number of e-
waste

3. Benefit
If the problem solved:
• Save money from buying battery
• Reduce the number of e-waste
Impact
If the problem solved:
• Reduce the number of landfill
• Battery’s lifespan increase

5. Problem definition:
How to increase the lifespan of battery used in
common watch
Root cause :
Limited storage of electricity stored within a coin
battery

6. S-Curve Analysis and Trend
With no exception, development of common watch follows this pattern as well as
other engineering product.

7. Time Frame Stage Evolution Engineering Trend
1600 - 1657 Birth
Pocket watches
- Evolving of clock
watches into typical
pocket watch
shape, rounded
and flattened with
no sharp edges
Increase ideality
1920 - 1950 Growth
Wrist watches
- An alternative to
allow user to access
to watch while
keeping both hands
full on the controls
Stage of technological
evolution

8. 1950 - 1969 Growth
Electric watches
- First generation electric-
powered watch is being
introduced
- It keeps time with a
balance wheel powered
by a solenoid
Stages of technological
evolution
1990 Maturity
Radio controlled
- Watch's quartz oscillator
is set to the correct time
daily by coded radio time
signals broadcast by
government-operated
time stations using a radio
receiver in the watch
- Allow to have long-term
accuracy as atomic clocks
which control the time
signals
- Capable of receiving
synchronization signals
from various time stations
worldwide
Stages of technological
evolution

9. Potential Ideas in predicting the future
of common watch
Power the watches using piezoelectric
• Rechargeable
• Rechargeable through vibration and
distortion. ( motion of walk cause vibration)
Additional features
• Increase individual safety by introduce
incorporated distress signal
• Automatic time notification
