Attending trade shows is a great way to get ideas.
The ProFood Show, March 26-28, is coming up in Chicago and I'll be walking around to see how different liquid and solid food products are handled, processed, and packaged.
This gives an idea what my factory could look like in the next several years and introduces me to vendors that might be a good fit for ingredients, packaging, and equipment. Even if you don't make food, seeing how things get made with brand new machines on an expo floor usually sparks some ideas for improvements in your studio.
I don't have an affiliation with the show. I have found that pre-registering is relatively inexpensive, and that usually a free registration code can be found with a quick search or by contacting an exhibiting vendor and asking nicely for a code so you can visit their booth.
