How many "systems" are there within the LEGO brand, and how many ways can you connect two pieces?
I think most LEGO builders are are of at least four current "systems" within the LEGO Group umbrella:
...there are definitely others from the archive such as:Which systems am I forgetting?
- System (standard LEGO Bricks and pieces)
- Bionicle (you could argue it is under the Technic umbrella)
(I excluded Galidor as it isn't really buildable.)
An alternate way to look at the various systems within the LEGO umbrella is by looking at the many ways two LEGO pieces can connect with one another:
Along the same lines as my first question - How else can two LEGO pieces connect that I forgot to include?
- LEGO Brick Connection
- Technic Pin/Socket connection
- Technic Axle/Axle Hole connection
- Small Towball
- Large Ball and Socket (Bionicle)
- Click Hinges
- Rotation Joint
- Small Pin (for small wheels)
- Pully/small wheel clip holder
- Clip/Bar/Handle/Ring/Hollow Studs/Minifig Hands
- Duplo Brick Connection
(I know there are a variety of illegal connections that take advantage of the LEGO Brick geometry, but that's not the focus of my question.)
Lastly, When thinking about your own LEGO collection, do you draw a hard line between these systems
(ex: Technic vs. System vs. Bionicle), or do you organize your collection based on the fundamental connection types
I described above, or do you organize in a different way
