First-time poster here: I write on innovation topics, have been Lego-infatuated for maybe 45 years now. My kid and I were assembling the 2022 succulents kit (#10309) and I noticed a piece that looked like a Robin Hood-type hat. Turns out it was (Forestman hat - 6395137). I've since disposed of the box but I distinctly remember it saying somewhere that no net-new pieces were developed for that set. Can anyone confirm this? It's the jumping-off point for a post on compositional innovation.
I don't see anything on the box indicating that there are no new parts in this set:
I also briefly flipped through the instructions and didn't see a mention of this. However, I do not believe that there were any new molds created for this set. We can see this by looking through the Rebrickable inventory.
While it does not appear to me that any new molds were made for this set, there were several recolors. For example, both of these elements appeared for the first time in this set:
As of May 2023, at least one element has only been used in this set:
This set could still support your thesis. Injecting a new color of plastic into an existing mold is much cheaper and more economically efficient than machining a new mold, and demonstrates the sort of compositional innovation you are discussing.
