Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
ActuationFunction ⊑ DesignedFunction
Realized in
ActuationProcess ⊑ PlannedProcess
Reusing the ActuationFunction from the already-enriched 'actuator' class, as pneumatic actuator is a subtype that shares the same identity-giving function but differs in power source mechanism.
2 Genus DeterminationDeterminação do Gênero
actuatorbfo:Object (BFO_0000030)
The parent_candidates list shows 'actuator' as already enriched in our ontology. All three source definitions clearly position pneumatic actuator as a subtype of actuator, differing only in the power source (pneumatic vs. electric, hydraulic, etc.).
3 Differentia SpecificaDiferença Específica
∃hasOperatingMedium.PneumaticPower

operates using pneumatic power (compressed air)

The pneumatic power source is the minimal differentiating condition. All definitions consistently specify 'operated by pneumatic power' as the distinguishing characteristic from other actuator types.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

These parts are universally required for pneumatic operation - pressure conversion mechanism, air supply interface, and pressure containment - regardless of linear/rotary subtype.

TransformationTransformação
pneumatic to mechanical energy conversion
Converts compressed air energy into mechanical work (force/torque and displacement). The specific motion type (linear/rotary) varies by subtype but all share this energy transformation signature.
Disjoint WithDisjunto com
electric actuator hydraulic actuator
C1: electric actuator, hydraulic actuator. Incompatible power source signatures - pneumatic vs. electric vs. hydraulic operation are mutually exclusive mechanisms
