Terminology for parts

From apm
Jump to: navigation, search

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

Crystolecular unit

  • (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)

Crystolecule fragment

  • (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
