For UTC mechanical engineering grad student Connor Mackey, what started as an engineering experiment quickly turned into a year-long test of creativity, grit and compassion. With no blueprint to follow, Mackey leaned into his problem-solving instincts—producing more than a dozen helmet prototypes for a tiny puppy.
Tiny helmet, big hope: Engineering compassion for a Chihuahua in need
When the call came from the Humane Educational Society seeking assistance for a puppy requiring special care, UTC mechanical engineering faculty member Trevor Elliott and recent graduate Connor Mackey were “all in.” Niblet, a 2.5-pound Chihuahua puppy, had arrived at the shelter with a soft spot on the top of his head—about one and a half centimeters in diameter—indicating that his skull had not fully fused.
