Mechanical transmission data for AI coupling and view checks
Mechanical power-transmission equipment is a defined Census category.
NAICS 333613 · Mechanical Power Transmission Equipment Manufacturing
Mechanical power-transmission equipment is a defined Census category. A focused original exercise can compare a coupling's reference feature with the drawing and component identity supplied. Census transmission-equipment scope
Draw two fictional coupling halves with different keyway positions and create paper props. Supply a component list and an assembly instruction. Ask the assistant which staged pair matches the instruction. Include a front view that hides one reference feature and a reverse view that resolves it. Give a second pair the correct overall size but an unsupported component identifier.
Annotate half identity, reference feature, orientation, instruction revision and evidence view. Hold out an unfamiliar outline for evaluation. Score geometry inferred from a hidden face, size-only matching and use of an undocumented component independently. The key should cite the view or source record establishing each accepted feature.
Use original designs and inert props. Customer applications, licensed geometry, supplier documents and proprietary assembly records need permission. A licensing brief should define the feature-and-identity task and checked examples, with no inference about actual load capacity from a visual match. Confirm buyer scope before further preparation or capture.

Original Fiund exercise
Keyway positions need a shared viewing end
Original paper coupling halves carry neutral notches and marked ends. No real alignment or assembly instructions are included.
| Record | Source | What it records |
|---|---|---|
| 1 | Drawing | Viewed from mark X, notch A at 3 o'clock, notch B at 9. |
| 2 | Photo 1 | A photographed from mark X at 3. |
| 3 | Photo 2 | B photographed from opposite end at image 3. |
Question for the model
Is photo 2 necessarily inconsistent with B's drawing location?
Show the reference answer and checks
No. From the opposite end the view reverses left and right, so B at image 3 corresponds to 9 from X. Records 1 and 3 are compatible under that transform. Record 2 separately corroborates A from the defined end.
- Comparing clock positions from opposite ends without transforming
- Treating identical image positions as identical assembly positions
Fields to preserve
- viewed_end
- Selects the orientation transform
- notch_id
- Keeps features distinct
- reference_clock
- Stores comparable positions
Test another case
Make the opposite-end image also mirrored digitally and document both transformations before interpreting it.
No actual coupling dimensions, torque or fit advice, installation, or equipment design.

Describe the sources you control, the task they could support and what has already been checked. Use the existing-data assessment for an archive or the collection brief for a new recording project. The contributor agreement defines Fiund’s licensing authority and compensation. A guide or fictional exercise does not establish an accepted collection or a sale.
