This weekly report discusses the progress of an engineering student group working on a water heater product. The group identified functions for their water heater including displaying water usage and temperature. They researched the basic circuit of water heaters and identified controlling stable temperature as an ongoing problem. Their analysis found increasing efficiency as a strong point but noted they lacked sufficient data and found adding new functions to water heaters challenging. Their next steps are to discuss function details and study electronics and circuits further.

Weekly Progress
Finally,This week we have a real product.It’s water heater.Function of our product are
Show how much water we used
Control stable temperature of water
Show temperature of water.
We had many problems about how to control stable temperature.And we started to research
about basic circuit of water heater.

Engineering Analysis
Strong Point
- Our group has a function that can be increase efficiency of water heater.
Weak Point
- We had too less data.
- Water heater is hard to find a new function.
Next Week Job
- Discuss about the details of function.
- Study about electronic device and circuit about function more than this week.
