Button and small-fastener data for AI hole-pattern checks

Fasteners, buttons, needles and pins form a defined Census category.

Fasteners, buttons, needles and pins form a defined Census category. An original button exercise can focus on component identity, hole arrangement and the reference face in a supplied drawing. Census small-fastener scope

Design fictional flat and shank-style button props, a component register and an order card. Give two variants the same diameter but different attachment features. Ask which component matches the order. Include a top view that hides the reverse feature and a bag with a readable family name but an absent variant suffix. The key should preserve both gaps.

Annotate component, variant, attachment feature, reference face and evidence view. Hold out a new outline for evaluation. Score diameter used as complete identity, a hidden reverse feature guessed and family information extended to an unidentified variant independently. A complete case should supply the second view and matching component record.

Use original designs and harmless props. Customer garment designs, licensed artwork, supplier declarations and production files need source-specific authority. A licensing brief should identify the feature-review task and checked examples. Confirm buyer requirements before preparing a larger archive or further authorized capture.

Original Fiund exercise

Two mounting styles share a face outline

Original paper button shapes include a rear-view sketch. A fictional order names a mounting style.

Fictional records supplied to the evaluator
RecordSourceWhat it records
1OrderFace shape round; mounting style shank.
2Front photoRound face, no visible through holes.
3Rear photoA protruding loop is visible on the same mock button.

Question for the model

What evidence supports the mounting style?

Show the reference answer and checks

Record 3 directly shows the rear loop, supporting the fictional shank style requested in record 1. Record 2 supports round face but cannot establish the mount by itself. Store front appearance and rear attachment evidence as separate observations for one item.

  • Inferring the mount from a round face
  • Using absence of front holes alone as proof of a rear loop

Fields to preserve

face_shape
Checks the visible style
rear_attachment
Identifies the mount
view_pair_id
Ensures the two faces belong to one button

Test another case

Use front and rear photos of different items with identical faces; require stable specimen linkage.

No commercial button designs, customer specifications, attachment instructions or durability claims.
