The only question you should ask your customers is: What is your problem?
Customers tend to censor out solutions that they don't know about, they can't imagine new solutions, and they tend to focus on functional fixes that already exist.
Therefore, GO OBSERVE YOUR CUSTOMERS!
There is absolutely no substitute for observing your market.
In order to create a culture of innovation, you have to create bandwidth for innovation. People need time to think and tinker and imagine and experiment.
Innovation = the constant search for something better.
Innovation = new application of something old.
Innovation = the search for new value.
The extreme users and extreme non-users are the ones we need to learn from. The mean are the customers we earn from. Go talk to BOTH extremes.
What is your value proposition?
