Not knowing if something has a proper solution is a pretty normal state of affairs. Make a plan how to analyze it: for the next n days, what are you doing each day. Collect data x, run analysis y, book time on machine z, etc. Really write it down the activities and deliverables for each day for the next 2 to 3 weeks to start.

It does not mean there is no space for creativity - the plan will not last as new things come to light, but the plan means you move forward in a structured manner.
