Product Realization
For this product development I worked with Mikey, Abby, Harrison, and Joyce from the Design classes. Our initial ideas were a thermos that can prevent burns, a universal paperclip, or a shoelace buckle. After meeting we settled on the Thermos with our initial designs pondering ways to inform the user about the internal temperature of the Thermos. The first test build was using a conductive material to bridge heat from the inside of the material to the outer. For the proof of concept I constructed a cylinder made to hold a bottle with a steel wire contact attached via a hairband. A rudimentary search stated 45-50 degrees Celsius is the upper limit of what heat humans can handle. When testing with heat I quickly found that the PLA had reached what is called it's glass transition temperature where it is still solid yet has become flexible and malleable, this was also concerning as the hot water leached chemicals from the plastic and started emitting fumes and discolouring the water.
