Weekly Progress
My company determined to invent ‘water heater’. We would add function about ‘save the
energy’ into this one so I chose to search the data about ‘pressure’ because the pressure is the one
thing that can help to save the water; if there is enough pressure, the water quality is as equal as
you want in few minutes.
There are two pressure switches; those are pressure switch and flow switch. Pressure switch
works when the pressure is as equal as the set value. This switch can damage to the transformer
when the water heater was working but don’t have any exit for water.
And the second one is flow switch. Flow switch works when the flowed water is as equal as the
rated value. This switch can use with faucet so there is few pressure, this switch can still work.

Engineering Analysis
Strong Point
- Both of switches are used in different work, so we had to choose the most suitable switch for
work.
Weak Point
- The pressure switch is risker for users than the flow switch.
Next Week Job
I will search another data that is ‘memory function’ for saving the water quantity we used in each
day.
