Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
EquipmentSupportFunction ⊑ DesignedFunction
Realized in
EquipmentSupportProcess ⊑ PlannedProcess
The identity-giving function is to provide structural support for equipment during manufacturing, transportation, handling, and installation phases. This distinguishes skids from other support structures by their mobility and multi-phase support capability.
2 Genus DeterminationDeterminação do Gênero
Assemblybfo:Object (BFO_0000030)
No domain-specific parent exists in the enriched classes that captures support structures. A skid is a causally unified artefact with physically connected components (frame, mounting points, lifting lugs) that can be assembled/disassembled, making it an Assembly rather than a simple MaterialArtifact. The parent candidates (ARTEFACT, SUPPORT) are too broad and map to MaterialArtifact level.
3 Differentia SpecificaDiferença Específica
∃bearerOf.EquipmentSupportFunction ⊓ ∃hasComponentPartAtAllTimes.SupportFrame ⊓ ∃participatesIn.HandlingProcess

A skid is distinguished by being designed specifically to support other equipment items and facilitate their handling, transportation, and installation through a structural frame.

The differentia combines the specific support function with structural characteristics (support frame) and operational capability (handling process participation). This distinguishes skids from other assemblies and support structures.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

These parts are essential for any skid to fulfill its support function - the frame provides structural integrity and mounting points enable equipment attachment.
Process Participation SignatureAssinatura de Participação em Processo
InputsEntradas
{'type': 'EquipmentItem', 'count': '1+', 'constraints': 'portable equipment requiring support'}
OutputsSaídas

TransformationTransformação
mechanical support and mobility enablement
Skids take equipment items that need support/transport and output the same items in a supported, transportable configuration. The transformation is purely mechanical - providing structural support and enabling handling.
