A Coffee Mug Error Proofed Against Tipping?

by Mark Graban on January 24, 2013 · 2 comments

I saw this at an office supply store today (but didn’t buy it). For all of the coffee making problems I have, tipping mugs over isn’t one of them (knock on wood).

This mug is advertised as having a clever mechanism that allows the mug to be lifted only vertically, preventing it from tipping over and spilling. Has anybody seen this in action? It seems to illustrate the Lean concept of mistake proofing or error proofing, does it not? For me, using a travel mug (or disposable cup) with a lid at least prevents tipping from becoming a mess (since only a small amount of coffee drips out of the drinking hole).

Though I haven’t seen this one in action, I have used mugs like these on boats. These do the trick !

That mug you shared looks like the simpler, more creative, less expensive way to solve the same problem…
