Most problems already have some sort of solution for them. When you make a claim that your solution is better than the existing solution you often provide a better UX in some respects. For this you have to make design decisions some of which don't have an accepted standard. This is where you are pushing the boundaries. On the other hand, UI style and UX naturally improves over time. Compare Windows 95 and Windows 7. There are certainly style and UX changes in the latter that are superior. A lot of people may not like Window's Ribbon interface but I think it was definitely an interesting new design, one which I think will in the long term prove to be better than plain drop down menus. So I guess I am making the claim that if you are really invested in your product you probably have ideas on how it could be improved and a lot of those ideas are uncertain but deserve time to be attempted.
