Overview • Problem statement • Background information • Product design specifications (PDS) • Components- Holding device- Heating mechanism- Temperature recorder/regulator • Final Design • Future Aspects • Questions
Problem statement Design a portable incubator that: • ships embryos and oocytes • maintains a temperature of 38 °C • is lightweight • is inexpensive • stores temperature data
Background Information • Demand for embryo and oocytes shipping • Current shipping devices:- cost $600 - $ 1200- battery powered- temperature not stored- shipping costs up to $80
Operational PDS • Maintain temperature at 38.5 C • Temperature recorded every half an hour • Withstand temperature changes (-20–100 F) • Weigh less than 12 lbs • Cost less than $250 • Power supply that lasts 30 hours • User friendly
Safety PDS • Meet air cargo shipping requirements • Airport customs friendly • Non-toxic chemicals • Enclosed circuitry • Safe handling
Components • Holding devices • Heating mechanism • Temperature storing/regulating
Temperature Storing/Regulation • Sensor in nutrient solution records temperature • Temperature data logger stores data • Negative feedback system regulates resistive • heating
Final Design Figure 1 (3/9/2002)
Final Design A. Temperature sensor C.Hole in PDMS B. Connection to battery D.Resistive wiring for heating
Final Design A. 4 slots for PDMS D. Connects to battery B. 9V Battery E. Connects to temp. recorder C. Temperature readings
Future Plans • Begin phase change chemical testing • Design the desired temperature display • Build the temperature data logger • Make precise specifications for PDMS • Build a prototype
