Terminology for parts
From apm
Things that influence terminology:
- (1) material: kind of material used
- (2) size: size of structure
- (3) type: structural or machine (or structure-of-machine)
- (UC) context of intended usage in convergent/hierarchical assembly
- (C) composability
- (M) exchange/replaceability
- (S) selfcontaindness
- (B) exterior geometry
Guideline for basic usage of common terms:
Strong suggestion: Try to not use these terms willy nilly unconscious about their meaning, but
rather try to use them based on what best fits the context.
- (0) part – perhaps the most general term
- (UC) assembly – something that already has been assembled from two or more parts
- (UC) sub-assembly – same as assembly but in the context of the next higher assembly level
- (UC) element – a part that is meant to become assembled or already is assembled into a bigger assembly
- (S) fragment – a part that in some sense can be considered a as a cutout of a bigger part => assembly needs welding/fusing/...
- (S) unit – something that is in some sense a self contained whole
- (B) block – a part with low aspect ratio exterior shape, usually convex
– the term focuses on this external shape and is preferably used for structural elements with not too much internal features of importance - (C) component – something composable with other components (unless noted typically reversible)
- (M) module – something that can be exchanged/replaced with some part that is internally different somehow
- object – seems too general – may be disjoint parts? ...
- thing – seems too general – a thing may not be a physical part

Crystolecule or Gemstone-like molecular element (GME)
- (1) material: – gemstone-like but not necessarily with diamond-like structure
- (2) size: – large molecule sized
- (3) type: – can be structural element or machine element
- (UC) usage: – part that is meant to be part of bigger assembly
Diamondoid crystolecule
- (1) material: – diamond like structure
- (2) size: – large molecule sized
- (3) type: – can be structural element or machine element
- (UC) usage: – part that is meant to be part of bigger assembly
Diamondoid crystolecular machine element
- (1) material: – diamond-like structure (implies atomic precision AP)
- (2) size: – large molecule sized (implies lower nanoscale)
- (3) type: – machine part
- (UC) usage: – part that is meant to be part of bigger assembly
- (1) material: – gemstone-like but not necessarily with diamond-like structure
- (2) size: – as big as crystolecules or sometimes quite a bit larger – still nanoscale
- (3) type: – can be structural element or machine element – perhaps more machine elements since these may come with larger minimal size
- (S) usage: – self contained unit – not a fragment that needs to be fused – no unpassivated welding sinterface bonds left – all further assembly by reversible form closure or weak non-covalent bonds – (meant to be part of bigger assembly is implicit)
- (1) material: – gemstone-like but not necessarily with diamond-like structure
- (2) size: – large molecule sized
- (3) type: – typically structural – fragments of machine parts pose challenges like locking degrees of freedom for covalent welding
- (S) usage: – fragment that is meant to be part fused to bigger part (potentially irreversibly)
diamondoid molecular machine element (DMME) and diamondoid molecular structural element (DMSE)
- (1) material: – diamond-like structure (implies atomic precision AP)
- (2) size: – large molecule sized
- (3) type: – can be structural element or machine element
- (UC) usage: – part that is meant to be part of bigger assembly
molecular machine element (MME) and molecular structural element (MSE)
- (1) material: – no constraints
– though something with at least topological atomic precision is typically assumed since molecular sized elements without any atomic precision hold limited functionality
– that is: they can barely be called machine/structural elements - (2) size: – large molecule sized
- (3) type: – can be structural element or machine element
- (UC) usage: – part that is meant to be part of bigger assembly
