Every quick connector is a material artifact that bears a quick connection function, and conversely.
First-Order Logic TheoryTeoria em Lógica de Primeira Ordem
[Definition]∀x (QuickConnector(x) ↔ MaterialArtifact(x) ∧ ∃f (QuickConnectionFunction(f) ∧ bearerOf(x,f))) — Steps 1–3: genus + identity-giving function
[Function axiom: QuickConnectionFunction]∀f (QuickConnectionFunction(f) → ∀p (realizedIn(f,p) → QuickConnectionProcess(p)) ∧ ∃p (QuickConnectionProcess(p) ∧ realizedIn(f,p))) — Step 1: ∀ preserves type-type identity; ∃ rules out vacuous functions never realised
[Process participation signature]∀x ∀f ((QuickConnector(x) ∧ QuickConnectionFunction(f) ∧ bearerOf(x,f)) →
∃m (PortionOfFluid(m) ∧ participatesIn(m,f)) ∧
∃e (PortionOfFluid(e) ∧ participatesIn(e,f)) ∧
processType(f,FluidTransport)) — Step 5: typed participants in the realising process
