We worked with a team of engineering students at the University of Wisconsin Platteville during this year's spring semester. Their task was to come up with new, leakproof, lid design concepts for our Temperfect mug. Here are some of the designs that made it to the prototype stage.
The ones they focused on were actuated through the lid with magnets on a sliding, and locking, puck which actuates the sealing mechanism on the inside, also carrying one or more magnets. It worked well in their testing, with a leak-free seal against up to 5 psi internal pressure.
This kind of project is good for us because it generates fresh ideas and gets them tested, and good for the students to get experience with a real-world problem (not to mention a degree!). Thanks Sam, Joah, Parker and Adam, (and the staff at UW-P) it was a pleasure working with you! (dean)
