Robotic Rice Cookers
Wahiawa Middle School -
rice cooker was invented in Japan to meet
domestic needs. Women usually cooked the
rice by hand, but as women began to enter the work force, the need to
cooking time became desirable. Before
WWII, a majority of the Japanese women worked in family businesses such
small stores or family farms, giving them flexible hours.
By 1950, about 48% of the women were in the
work force. Instead
of having to watch
the rice cooking, time could be better spent preparing the rest of the
doing other chores. In 1956, the first
effective rice cooker was sold.
It is no surprise that the
women working coincided with the testing of better rice cookers.
success of the rice cooker as a household appliance was due to the
rice in Asian countries. Rice was usually
the staple diet in these countries & in Hawaii.
This made the rice cooker more of a necessity in Hawaii
and many Asian countries, than a convenience as it was on the
1997, 80% of the women in the work force in Japan
worked in the public and
private sectors. This was a big increase
compared to 1960, during which only 40% of the working women worked in
and private sectors and 60% worked in family
businesses or were self employed. The
shift to jobs in the
public and private sectors decreased the flexibility of their working
the United States,
only about one in three women was in the work force in 1950. Contrast this to nearly three out of every
women in the work force by 1998.
time dedicated for cooking has become more limited, increased
automation in the
rice making process is desirable. If the
rice could already be prepared by the time people returned from work,
could be started faster. At present
there are timers to start the rice cooking process but that
leaving the rice soaking in water all day, leading to mushy rice.
If there was a rice cooker that could wash the rice at a set
then begin the cooking process, people would have perfectly fresh
them when they returned home. That is what
our solution tries to solve.
