Design Conjecture Four, Porta-Cool
The Porta-Cool is a compact cooler and eating area that is perfect for families on the go. Features included in the Porta-Cool include a double lined cooler to store fresh food and beverages, a removable cutting board, a tabletop to share a meal with family inside of the car or the trunk of the car, built-in storage and a door that slides over to seals this area when the car is in motion, and four cupholders to accommodate every passenger's beverage.
The conceptual design of the Porta-Cool was inspired by an article discussing how the needs of humans are changing with the emergence of new technology. Technology is increasing at a rapid rate which has allowed for the development of self-driving cars. In turn, the driver no longer needs to keep an eye on the road to drive but rather can enjoy the ride alongside other passengers.
