Axiomatization Decision Log
1
Identity-Giving Function
Function class
ShakingFunction
⊑ DesignedFunction
Realized in
ShakingProcess
⊑ MechanicalSeparation
The identity-giving function is the capability of shaking - creating vibrating or oscillating motion. This is what distinguishes a shaker from other equipment types. The shaking motion is typically used for separation, agitation, or material handling purposes.
2
Genus Determination
Assembly
bfo:Object (BFO_0000030)
Causally unified material artefact composed of physically connected,
separable MaterialComponent parts. Satisfies
Assembly ⊑ MaterialArtifact ⊑ bfo:Object.
No specific equipment superclass exists in the parent_candidates. A shaker is a mechanical device with multiple physically connected components (motor, vibrating mechanism, screen/container) that work together as a single causally unified unit. It fits the Assembly pattern as it has removable subcomponents but maintains a single causal boundary for maintenance purposes.
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
All shakers require a vibration source and a shaking element. Specific implementations vary (screens for separation, tables for compaction, etc.) but these core components are universal.
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
MaterialEntity
— mixed or heterogeneous material requiring agitation or separation
Outputs (O)
MaterialEntity
— agitated material or separated fractions
Transformation (T)
mechanical energy applied to create vibrational motion for material processing
Shakers take material inputs and apply vibrational energy. Output may be the same material in agitated state or separated into multiple fractions (as in shale shakers separating cuttings from mud).
5
Axiom Mode Decision
Necessary + Sufficient
— modelled as a defined class
(≡, EquivalentClass). Automatic classification is
appropriate for this concept.
Disjointness Axioms
Centrifuge
C4: Centrifuge. Centrifuge uses rotational centrifugal force rather than vibrational motion. Static filters use passive filtration without mechanical agitation. These represent incompatible mechanical transformation signatures.
Cross-Standard Observations
ISO 15926 provides the most generic functional definition, while SLB and OnePetro focus specifically on drilling mud separation applications (shale shakers). The functional approach captures both the generic vibrational equipment class and its specialized drilling applications.
