Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
SeparationFunction ⊑ DesignedFunction
Realized in
SeparationProcess ⊑ PlannedProcess
The identity-giving function is separating solid particles from fluids through physical filtration. This aligns with the already-enriched SeparationFunction in our ontology, used by separators and centrifuges. All definitions converge on this separation capability as the defining characteristic.
2 Genus DeterminationDeterminação do Gênero
MaterialArtifactbfo:Object (BFO_0000030)
No domain-specific superclass exists in the parent candidates that is appropriate. 'FunctionalObject' and 'Artefact' are too abstract, 'PipeFitting' is too narrow (strainers can be standalone units), and 'other mechanical equipment' is not a proper ontological class. Strainers are typically monolithic or simple assemblies that function as single causally unified objects, making MaterialArtifact the appropriate BFO root.
3 Differentia SpecificaDiferença Específica
∃bearerOf.SeparationFunction ⊓ ∃hasComponentPartAtAllTimes.FilteringElement ⊓ ∃participatesIn.SolidLiquidSeparationProcess

A strainer is distinguished by bearing a separation function realized through a physical filtering element that separates solid particles from fluids.

The differentia specifies the particular type of separation function (solid-liquid separation) and the necessary physical means (filtering element with screens/perforations). This distinguishes strainers from other separation equipment and from non-separating fluid equipment.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

These are the minimal universal parts required for any strainer to function - a filtering mechanism and a body to contain it. Specific configurations (basket shape, Y-shape, etc.) are subtype-specific.

TransformationTransformação
mechanical separation of solid particles from fluid stream
Strainers take a contaminated fluid input and produce a cleaner fluid output plus captured solid waste. The transformation is purely mechanical separation without phase change or chemical alteration.
Disjoint WithDisjunto com
HeatExchanger Pump Compressor
C4: HeatExchanger, Pump, Compressor. Strainers perform mechanical separation while heat exchangers perform thermal energy transfer, pumps add mechanical energy to fluids, and compressors increase gas pressure. These represent incompatible process signatures.
