In Terry Pratchett's marvellous Discworld series, I loved his inventor, Bloody Stupid Johnson, whose ideas never seemed to quite work the way the inventor had envisaged!
So in your created world, who are your creative people, your inventors, your engineers etc? It helps to bring a world to life if we the readers can see at least part of how your world works for those who live in it. What are the technologies? Are your societies developed or are people held back by the lack of progress?
Does your world have anyone whose inventions go wrong or whose ideas get pinched by someone else? (There is a whole raft of stories there about how someone would cope with that/get their ideas back and so on).
