It's not important to write your ideas on physical or digital notebook, what matters is changing the environment and the activity.
For example, I often ride a bicycle, about 10 hours at a time, sometimes I listened to music and thought about problems (most of the time I imagine what the product looks like, how to interact, what the process is, etc. This feels so amazing) while riding my bike, and recorded the results of my thinking in an resource manager(used as a note-taking app) I created. In this way, I solved many problems, made my brain clearer, and released the fatigue of the week.
