You should do brainstorming sessions with your team where you diverge and then converge. What I mean is: 1) get a white board/wall, post-its, and markers. 2) have everyone, independent of each other, write ideas on post-its and put on the wall. Don't judge ideas, just put them. Lots of them. Don't put your names on the ideas. 3) when you literally run out of steam, which could be a couple of hours later or even more, as a team start discarding ideas that don't make sense or work for your team. 4) you may have to do this a few times so that you get a feel for the process. In the end you should have some really good ideas that you as a team have agreed upon.
