Axiomatization Decision Log
1
Identity-Giving Function
Function class
FiltrationFunction
⊑ DesignedFunction
Realized in
FiltrationProcess
⊑ MechanicalSeparation
Filter cartridge shares the same identity-giving function as the broader Filter class already enriched in our ontology. The function is to collect/remove particles from a fluid stream through physical or chemical separation mechanisms.
2
Genus Determination
Filter
Filter cartridge is clearly a subtype of Filter (already enriched in our ontology). The parent candidates include 'Filter' which is the most specific and appropriate genus. FILTER ELEMENT from ISO 15926 suggests it's a component, but filter cartridge is itself a complete filtration device that can be installed as a unit, making Filter the correct genus rather than treating it as a mere part.
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
Every filter cartridge must have a filter medium (the functional element) and a housing structure that creates the cartridge form factor for replaceability.
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
PortionOfFluid
— containing suspended particles or contaminants
Outputs (O)
PortionOfFluid
— reduced particle/contaminant content
PortionOfSolid
— collected particles retained in filter medium
Transformation (T)
physical separation of particles from fluid stream with retention in filter medium
Filter cartridge accepts contaminated fluid and produces cleaned fluid plus retained contaminants. The transformation is purely physical separation without changing fluid composition beyond contaminant removal.
5
Axiom Mode Decision
Necessary conditions only
— modelled as a primitive universal
(⊑, SubClassOf). Identity is grounded in designed
function and cannot be reduced to a property checklist.
Constructive type where the structural differentia (cartridge geometry and replaceability) is necessary but making it sufficient under OWA could lead to false positives - other equipment containing replaceable filter elements might be incorrectly classified as filter cartridges rather than their proper specialized categories.
Disjointness Axioms
FilterPress
C1: FilterPress. C?: Strainer [kind_ambiguous]. Filter press uses compression/decompression cycles incompatible with cartridge replacement; strainer typically uses fixed mesh incompatible with cartridge medium replacement
Cross-Standard Observations
All three sources provide nearly identical definitions focusing on the particle collection function and the cartridge form factor. ISO 15926 additionally notes it's an ARTEFACT and FILTER ELEMENT, confirming its manufactured nature and component relationship to larger filter systems.
