I often get collectibles like this.
They are just out of reach of a jump. So, is there a way to jump just a small bit higher (or by another mechanic to just get a little bit higher) to get those pieces?
You can use many characters attributes and skills to acquire these.
There are mainly two options that can be accessed simply by progressing the game and thus are available for free:
the Wind Catcher gadget can be used to place a wind current anywhere;
if you have the Traveler as Geo (available as soon as you enter the Liyue region), their elemental skill can create a platform to climb;
Other options are available, but they all require access to limited characters that as now can only be acquired from the gacha wish system (either with paid or free currency you get from rewards in the game):
Also, characters height differs, sometimes it could be enough to switch to higher one. For example, Kaeya is one of the tallest characters available for free.
I see you're using the anemo traveler in your screenshot, these "just out of reach" puzzles in Liyue are usually designed with the geo traveler in mind because he/she can easily summon a boulder and climb atop to reach the item.
Try changing your traveler to Geo at the nearest statue and give it another shot.
