Basically the answer is always the same in UX design. Go back to users to understand what would/could work and get the inspiration from there.
Often a time I will be doing things like ethnographic observations to see what and how people do things in real world and what problems they might be experiencing.
You might even do this by watching various YouTube videos of real people doing things that you are designing for.
User testing is a great source of this 'inspiration' as well.
You can look at how others have solved the problem and try and do it better.
You can drink more RedBull and hope for inspiration! ;-)
You can also lobby to have me work with you in the company (jason@flexewebs.com) and I can coach you to become a person who always has at least 4-5 ideas for every problem. I'm available at the moment.
Hope that helps. Best regards.
