Design Problem
Temperature sensitive pharmaceuticals
• Vaccines, medicines, and diagnostics
Transport
• The current system is ineffective
Storage
• No energy grid in most remote areas
When pharmaceuticals are spoiled, there is a
high expense in terms of resources and lives

Design Brief
Develop a cooling device for
transport to and/or storage in
remote areas
But How?
•
•
•
•
Reliable cooling within required range
Maintaining cooling for extended periods
Self-reliant energy source
Monitoring of temperature range in device
Transport Background
• 130 million shipments of temperature
sensitive pharmaceuticals each year
• Cost of batch of spoiled vaccine $10,000
• “Cold Chain” is a series of cold places
used to store product during transport
• Failure when too hot or too cold
• Remote locations have higher chance
• Not always known if failure occurred
Storage and Dispensing
• Remote villages often lack a
power grid
• “Vaccine Day” programs not
effective
• Medications often administered
by untrained personnel
• Trained refrigeration technicians
not available

• Instant cold packs
• Self cooling beer cans
Constraints and Specifications
• Consistent temperature
• 2-8 ºC for most pharmaceuticals
• Self-sufficient
• Self contained energy
• Relatively inexpensive
• $500-$700
• Easy to use and fix
• No specialized knowledge
• Must be reliable
• Fool proof and damage proof
