In the US at least, please stop analyzing these types of social interactions literally. The subtext is quite different. Basically, "Hi, how are you doing?" is the equivalent of "Hi, I'm being a pleasant person going through this standard cultural greeting." Expecting something more from this pattern shows a poor understanding of the culture.
Breaking out of this is easy. As other people have mentioned, simply departing from the script is effective. For example, you can follow-up "Hi, how are you doing?" with "How's your day been going?" or "It's pretty busy in here." There's also subtext here and it's basically "I'd like to engage in a conversation."
I'm not even sure how you ask a person how they're doing in a way that lets them know you mean it without sounding condescending.
