Here's a few examples of Octave Displacement using Arps, which I liked.
All this involves is moving a note in an Arp down an octave and continuing the Arp in that octave.

Is "arpeggio" really that hard to write? Apparently.

Here is another Octave Displacement using Arps.
This example uses three separate Octave Displacements.

I don't think that octave displacement is the proper term for this because you're not "displacing" notes. Your latest example is an ascending arpeggio pattern repeated over different chords, the pattern being chord tones 3-1-3-5-7-(5) - with the 5th repeated to serve as a pickup note to the next chord arpeggio.
-
Yeah so octave displacement would be like if you had a pattern of any kind …
say … C E G B …
The order of pitch letter names never changes, but at some point you can take one of the notes up or down the octave and continue from there
-
Or you play get together with a few people playing instruments that are 1 or more octaves apart and play the same line "unison" except not all at the same time. Cool, spatial displacement!

BTW, done right (on a single instrument) the principle can also be called a "fugue"

Still, many fugues begin like canons, where a newly entering voice repeats the theme in a different register. Do they only officially become fugues when something a bit more complex starts to happen?
(IIRC the original by Reincken is for 2 melody instruments + BC)

All the extra stuff like stretto, pedal points and clever stuff with retrogrades and what have you are finessing the basic structure. To my limited knowledge they seem to a natural development of modulating verset structure, which would make sense. I always feel they have a lot in common with preludes, weirdly.
You also have things like Fughettas that are not totally proper fugues. The two part inventions have aspects like a fugue, but are not quite fully fledged fugues. I think in this case you tend to see the canonical entires at the octave rather than the fifth which is more common in ‘proper fugues’ but something tells me this isn’t a hard and fast rule either .
On the other hand we all think of Bach as the fugue guy but his fugues were unusually rigorous for the era. I expect the romantics picked up a lot on what he did when defining their ideas of fugue.
It’s a bit of theme. It’s really quite hard to pin down the exact nature of things like Sonatas and Ricercars. Even the Passacaglia might be a ground bass or Rondo style form depending on the country and time period.

I like it! Super easy and effective!

Regardless of what you call this, it's a great way to practice arpeggios over chord changes, i.e., play the diatonic chord tones in various combinations and use chromatic passing tones to connect the arpeggios. And this exercise can be as simple or complex as you want, for instance, you could start with only 1 or 2 chord tones from each chord and play them in various rhythms, then add 1 or 2 more chord tones, etc.

C E G B || C E G B || C E G B || C E G B
underlined notes down an octave.
simple move to create variations for arpeggios and melodies.
worth practicing and assimilating in my opinion.

If you only start the arpeggio on the root note, you could miss out on some great sounding Octave Displacement phrases.
Below: This Octave Displacement phrase starts on the note C of a Dm7 arpeggio.
