Hmm, I'm not so sure. Couldn't this also be considered a Kaizen approach? The engineer is making a small, incremental improvement to the process to reduce defects. That seems like the kind of continuous improvement that Kaizen is all about.

Ooh, a quality engineer question! This is right up my alley. I think the answer is clearly Poka Yoke. The engineer installed a device that physically prevents the cabinet from being closed if the medication caddy is not in place. That's the definition of a Poka Yoke, a mistake-proofing mechanism.
