I know I was stretching it, its just StarTrek is so damn inspiring sometimes. Ok how about this one, I have to admit I took it from StarTrek too though;
A dual-door system which opens automatically when someone approaches the doors; the right door going to the right - INSIDE the wall, the left door going to the left - INSIDE the wall (I KNOW WTH!) on the opposite side of the right door. Its somewhat radical but I think something like this COULD be accomplished. Ofcourse you'd have to modify the walls somewhat, but that shit just gets too technical for me.
And that button you press on your breast to talk - I mean FAN-T-ASS-TIC, imagine pressing your breasts all day long to talk about something

) so invent a female version of it where you need to put a whole palm of the hand on the breast in order to talk, I think you get a winner there!!
