The last straw
You're tired, you're stressed and you're dealing with a fussy child who woke up on the wrong side of the bed. You place your one lifeline (a venti cappuccino) into your Uppababy cupholder and BOOM it flips over and spills all over the floor. Annoying, right?
I analyzed the old cupholder to see where we could improve. My proposed solution consisted of a higher center of gravity, a more secure cup holding mechanism and a keyed snap feature to lock rotation.
I thought through several concepts for a moldable assembly strategy. Several options were considered including over-mold tabs, snap fit spring fingers and friction fit trapped TPU parts. We ended up with an elegant two-part assembly; the main cup and a ring of flexible fingers both molded in BPA free Tritan.
