Purpose and description
Enable an AI agent to recognise a hand fan, assess its usable condition and determine appropriate handling, cooling, display or preservation actions.
A hand fan is a manually waved implement with a broad surface that displaces air, chiefly to promote personal cooling through increased air movement over the skin.
It can be Classify an example as a fixed or folding hand fan and distinguish it from a powered fan.; Determine whether and how a folding fan may be opened or closed.; Assess suitability for manual fanning from grip, mass, clearance and condition.; Locate damage in the surface, supports or joints and restrict affected actions.; Choose supported storage or display arrangements for its construction and condition.; Record decoration and attributed cultural uses with evidence and uncertainty..
Distinguishing features
The user moves the implement itself through the air using a grip or handle; a powered rotor does not generate its airflow.
Its intended air-moving action uses an exposed broad surface rather than air expelled from a compressed chamber.
A fixed surface can qualify: folding is an optional construction feature, not the defining test.
A folding example opens into a usable air-moving surface; foldability alone does not distinguish it from an umbrella or folding screen.
Purpose, design or documented identity distinguishes a hand fan from a card, plate or other object temporarily waved for cooling.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 16 findings · 27 questions.
Fan identity and boundaries Establishes what makes an example a hand fan and which construction form it represents.
A broad surface, a folding mechanism or a fan-shaped silhouette alone does not establish membership.
Manual air-moving identity
Connects the implement's design and documented purpose to manually generated airflow.
Hand fan membership
Record evidence that the object was designed or identified as a manually waved fan, including when its current role is display or ceremony.
- What design features or documentation identify this as a hand fan? definition
- Does its airflow come from waving the surface, a powered rotor or another mechanism? boundary
Fixed and folding forms
Distinguishes surface architectures without making folding mandatory.
Surface deployment form
Describe whether the working surface is permanently spread, unfolds on supports or is formed by spreading slats.
- How is the broad air-moving surface formed and, if applicable, deployed? definition
- Which observed features distinguish this form from a miniature umbrella, screen or incidental fanning object? boundary
Manual fanning and control Describes the hand-powered action, working envelope and evidence of useful air movement.
A hand fan's practical performance depends on how it is held and moved as well as its surface.
Grip and stroke
Records the intended holding area and clearance for repeated movement.
Usable fanning motion
Identify a supported grip and motion that avoid stressing the surface or striking nearby people and objects.
- Where can the fan be held without loading a fragile leaf, decorative attachment or loose support? action
- What are its mass and open dimensions, and what clearance does the intended stroke require? measurement
Air movement assessment
Keeps observations of airflow tied to explicit operating conditions.
Conditional airflow performance
Record airflow or user observations with opening state, distance and fanning motion rather than treating performance as a fixed property.
- Under what opening state, stroke rate, stroke range and distance was air movement assessed? measurement
- Does the observed air movement meet the stated use need without requiring unsafe handling? action
Surface, supports and opening Maps the fan's working surface to its supporting parts and deployment mechanism.
Fixed sheets, supported leaves and linked slats require different checks and handling actions.
Surface and support assembly
Records how materials and attachments form a surface that tolerates fanning.
Component and attachment map
Identify the surface, supporting sticks or frame, grip and their connections, preserving uncertainty about materials.
- Which materials form the surface, supports and grip, and how were those identifications established? provenance
- How is the surface attached, and which connections carry loads during waving? definition
Folding travel and restraint
Addresses pivots, folds, links and opening limits only where present.
Supported opening sequence
Record the intended opening direction and range, including any restraint or closure feature actually present.
- What pivot, folds, links or other features guide and limit opening? definition
- How can the fan be opened and closed without forcing resistance or trapping its surface? action
- What opening range is supported by observation or documentation? measurement
Damage, care and use readiness Connects fan-specific defects to decisions about operation, repair, cleaning and storage.
A fan may still open despite damage that makes repeated waving or further folding inappropriate.
Surface and joint failures
Checks the working surface, folds, supports and grip connections before use.
Defect-to-action assessment
Locate tears, split sticks, loose pivots, failing attachments or sharp fragments and relate each observation to permitted movement.
- Where are tears, splits, loose connections or deformation located relative to folds and load-bearing parts? measurement
- Which defects require stopping fanning, avoiding folding or obtaining a repair assessment? action
Care and supported storage
Selects care and resting positions from construction, condition and significance.
Material-sensitive care
Record justified cleaning and storage actions without assuming that all fans tolerate moisture, pressure or repeated closure.
- What material or finish evidence supports the proposed cleaning method? provenance
- Should this fan rest open, partly open or closed, and what support prevents strain on its surface and joints? action
Decoration, context and handling Captures features and documented roles that may change how a fan is interpreted or used.
Decoration and cultural significance can affect handling decisions even when a fan remains mechanically usable.
Decorated surfaces and marks
Records imagery, inscriptions and maker marks in relation to the fan's surfaces and opening state.
Evidenced fan attribution
Separate visible marks and motifs from inferred maker, date, origin or symbolism.
- What marks, inscriptions or images are visible, on which side and at what opening state? measurement
- Which sources support any claimed maker, date, place of origin or meaning? provenance
Documented role and operation permission
Links everyday, ceremonial, performance or collection roles to appropriate actions.
Role-dependent handling
Record documented use and applicable handling restrictions without deriving them from appearance alone.
- What evidence establishes this fan's everyday, ceremonial, performance or collection role? provenance
- Do its condition, owner instructions or documented cultural protocols permit fanning, demonstration or display? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
